how can I randomize my MAC address every time my WiFi is turned on?
Given the increased prevalence of systems which track people's movements by their Mac addresses I'd like to obscure mine.
I have a rooted galaxy note 2 with busybox installed.  I can change my MAC address like so:
busybox ifconfig wlan0 hw ether 11:22:33:44:55:66

however, if I disable and re-enable my wireless, or I reboot my phone, it gets forgotten.  is there somewhere I can put a script so it will be run every time my wireless turns on?

Give pry-fi a try

How about Chainfire's tool Pry-Fi which was announced over at XDA?
It works great and it is available via the official Google play-store at:

https://play.google.com/store/apps/details?id=eu.chainfire.pryfi

Here’s a screenshot showing the tool in action…

I tried Pry-Fi.  Despite my phone being listed as tested, it caused wi-fi to become entirely unusable.  I couldn't even see any networks to connect to.  I had to uninstall to get access to my home network again.

You could do that using e.g. Tasker, the mighty automation tool:

Condition: Monitor Start (i.e., Tasker was started; alternatively: Device Boot, i.e. boot process finished)
Task: Run Shell, with your command as parameter

If you like it more fancy, you could even use Variable Randomize to generate a different MAC each time...

Would this trigger as part of the process of going online or shortly afterward?  If possible I'd like to not broadcast the hardware's MAC at all.

This would trigger where you defined it, as described: Monitor start is when Tasker gets activated, which is usually immediately after boot (or when you start/restart Tasker, or activate its Monitoring service manually). If you use Device Boot as condition, it would only get "triggered" after boot, but not when you start/restart the Tasker monitor manually. So in both cases, it would be applied immediately after boot. I cannot say whether network initialization might be faster.

The activation would have to track when wi-fi is turned on, and change the MAC before any packets are broadcast.  I'm not all that confident that that could be relied on, but perhaps I'm wrong.

@mc0e If you have doubts on that, add a second profile with a different condition (something that triggers on network changes), and apply the same task to it :)

In addition to the other answer with Tasker ("You could do that using e.g. Tasker, the mighty automation tool:"), here a little Task (description export) with randomizing the MAC:
TestMacChanger (130)
    A1: Variable Set [ Name:%count To:0 Do Maths:On Append:Off ]
    <randomstart>
    A2: Variable Randomize [ Name:%random Min:0 Max:15 ]
    A3: Variable Convert [ Name:%random Function:Decimal to Hex Store Result In:%rhex ]
    A4: Test Variable [ Type:Length Data:%rhex Store Result In:%len ]
    A5: Variable Set [ Name:%rhex To:0%rhex Do Maths:Off Append:Off ] If [ %len eq 1 ]
    A6: Variable Convert [ Name:%rhex Function:To Upper Case Store Result In: ]
    A7: Variable Set [ Name:%mac To:%mac:%rhex Do Maths:Off Append:Off ] If [ %mac Set ]
    A8: Variable Set [ Name:%mac To:%rhex Do Maths:Off Append:Off ] If [ %mac !Set ]
    A9: Variable Add [ Name:%count Value:1 Wrap Around:0 ]
    <randomend>
    A10: Goto [ Type:Action Label Number:1 Label:randomstart ] If [ %count < 6 ]
    A11: Variable Set [ Name:%mac To:00:11:22:33:44:55 Do Maths:Off Append:Off ] If [ %mac !Set ]
    A12: Flash [ Text:%mac Long:On ]
    A13: Run Shell [ Command:su
busybox ifconfig wlan0 hw ether %mac Timeout (Seconds):0 Use Root:On Store Output In:%output Store Errors In:%error Store Result In: Continue Task After Error:On ]
    A14: Flash [ Text:%error Long:Off ] If [ %error Set ]

This is doing a loop for 6 random hex values to get a random mac as e.g. 01:4F:89:BA:3F:0C
Then it is setting this random mac as own mac.
I can see the new mac with this command:
busybox iplink show wlan0

After a reboot the old mac is reset.

Use Chainfire's app called Pry-Wifi which does exactly that.

As things move forward, I've got a new phone (a Pixel 5a), which has such a built in option, but that's for Developers.
First I had to enable the developer feature (see here for original):

Open Settings » About Phone
Click on Build Number 7 times

Next, I went to the Developer feature (you can use the search feature if you have a slightly different phone):

Open Settings » System » Advanced » Developer options
Scroll down to "Wi-Fi-enhanced MAC randomization" and Enable

As you probably know, the default is to generate a random MAC address once per network, address that gets saved once and for all unless you change the above flag. So with the default, if you use different WiFi networks, it at least will use a different MAC for each connection point.

Thanks.  https://source.android.com/devices/tech/connect/wifi-mac-randomization has some more info on this.

I feel like this could be done with a bash script or editing the init file to include the command you have here.

This isn't helpful; what would OP put in the script? Where would it go?

This is really a repeat of stuff I've put forward in the original question.  I have no problem writing a script, but I don't know where it would need to go in order to be triggered each time my phone goes online.

In addition, that would require modifying the boot image; init scripts are part of that. Any modifications of init files in the "mounted file system" will be lost after boot (see e.g. initrd @ Wikipedia for details).

If I get a way to set the MAC address that survives the NIC going up and down, that's a step forward, even if I have to modify the script after each phone reboot.  Especially so if it means the MAC address gets set before any packets get broadcast each time the wifi link goes up.

Color note backup
I am using android jelly bean 4.1.2. I took the backup of color note notes then i have formatted my mobile. Now when I try to restore what I already took a backup I couldn't find the backed up notes in color note restore option. The problem is that I couldn't find the backup data inside the color note application to restore it though I have it in my memory card.

Can you post the path with file name that you are looking for?
may be something like /sdcard/colornote/backups/2013-12-8_back.xxx

storage/sdcard/colornote/backups/

i have the backup where is specified above

But this is not been shown inside the color note application from which i can restore

So my assumption is that the path is empty. Have you tried searching the file on the entire /sdcard if you remember the name of the file or only a bit of it?

No i have all the files there in the specified path

Would seem to be closely related to How to restore ColorNote notes after factory reset?

I downloaded colornote, made a backup on the sdcard and found they store two files for each back up(.dat & .idx). I found this on /sdcard/data/colornote/backup/ , have a look at there.

ya i have those both files @ ironblossom.....Can i do anything with those files explicitely

Turns out .dat is for the password of the note and .idx is the note itself.What you get from Setting>>Backup>>SDCard Backup at the saved back up data?

You have to go to the path /sdcard/data/colornote/BACKUP/ and there should be the idx and dat files. If you have them and you want to backthem up, it asks for the password. I solved this problem by adding another android device.

Take another android phone and install colornote
Make a new note and save it
Go to settings and turn off AUTO SYNC. Now you can backup manual
It will ask you about a new master password ( type in 0000 or whatever)
Now connect your android phone and copy the whole folder and paste it into the second device in the same colornote folder /sdcard/data/colornote/backup/
Start colornote on the second device.
If you go to backups, you will see the backup from your first device

The backup will work now and you can easily write it down or take pictures of your notes to put them back on your first device.

"U" is not a word. Please don't use txtspk here.

How can I get the lock screen sounds from Android 4.3 back? (upgraded to 4.4)
I have a Nexus 7 and I updated to android 4.4 after the upfate had been downloaded and waiting for a week. I miss the crisp sounds of the 4.3 lock screen, it made me like my device. Now its all changed without warning and I'm upset left feeling like my device isn't really mine. Is there a way to fix this? Likewise time/battery/WiFi icons at top have changed from blue to gray. Anyway to change just these two aspects without rooting or factory reset? Thanks.

A factory-reset will not help you for either of them. Both are intentional design changes with Kitkat – so you either can have Kitkat with those, or downgrade to 4.3 to get your former feelings back, sorry. While there might be ways for the sounds (if you can get hold of the sound files, and set them accordingly), there's no way for the notification area (at least not without root) I know of.

You could probably download a custom Rom from xda and find and extract the sound files from
/system/media/audio/

You should be able to put them into the relevant folder on the 'sdcard'
/sdcard/alarms/
/sdcard/Notifications/
/sdcard/Ringtones/

where they will get picked up by the OS.
As for the notification icons, without rooting and customising the relevant files (I'm not sure exactly which) there is no way to change them from white to blue.

I think some of the sounds are actually part of system APK's and would require recompiling the specific parts of the system, or perhaps something with Xposed Framework. The same can be said of notification icons. I could easily be wrong about the sounds though.

WidgetLocker will allow you to adjust the lock screen sounds, the only downside is you can't use it with a pin. The status bar was a change to make android look better, you can't change that without changing ROMs or using Xposed Framework.
https://play.google.com/store/apps/details?id=com.teslacoilsw.widgetlocker

System sounds are stored in a folder accessible without root. I forget the path, but all you have to do is replace the files with the sound you want.

The path would be required to answer this question.

How to pay for my kids apps?
Here is the story. I have two kids (5-7 years), they have their Android tablets... and I have the credit card. I have created two google accounts, each for one tablet. I want to buy apps for them, but I don't want to enter any details of my credit card to their google accounts, because the theory is that they will be using these accounts in future to communicate, browse etc. I don't want them charging my card without my knowledge.
A while ago, when buying something in the google play store, I was able to select between one of the tablet accounts and my own account. I then had to enter the password to my own account and was able to install the given app. Now this seems no longer to be possible.
I am lost. I am a 40+ year old Un*x user and I am confused and frustrated by Android. Is there a way of buying apps for my kids that is safe?

While I already answered giving you an alternative approach, just for curiosity: What Android version are those tablets on? AFAIK you still can chose the account used for "Play shopping", provided it was configured on the device.

There's a much easier way, but it may not be supported in all countries: Buy them each a Google Play Gift Card, and attach it to their accounts. They come in different "sizes", so you can limit the amount they can pay. No identification stuff connected to the cards, and once they're used up there's no more use for them (of course, you can buy the next one).
Another positive aspect: you might decide to let your kids use them themselves. The danger is just as high as the value of the card (though content might pose a risk). So it's like "pocket money" for learning "monetary responsibility" :)

That would be indeed a perfect solution... if there were gift cards for 5 EUR and less (we are talking "70 c fruit ninja" here). And, if I were able to buy them online. But I think this is the way I'll try to go.

By default one still has to input the password before installing paid content from Playstore, so there's an additional layer of "security". Agreed, with the smallest card coming for EUR 15, you could buy an entire fruity ninja army. But your kids grow, and might soon need some useful apps for school ;)

A friend of mine asked me about this a few days ago and I told him I wasn't sure.  This is a very good idea, and I will mention it to him.

“but it may not be supported in all countries” yeah here is the point where this fails ☹

In Playstore, the user is prompted for the password (unless you disabled it) every time before a purchase can be made.
So what you can do is, make a Google Account JUST for playstore Apps that's logged in across all your and your kids Google Devices.  Have every device logged in to that account on top of whatever other accounts your kids personally use on the given device.
That way you can buy whatever apps you want, but they can't since, even tho their device is logged in and has access to all the apps you purchased thru your Google Apps account, they can not purchase new ones without your password.
They can't see the details of your CC since Google will prompt for the password every time the user attempts to access Account Information.

you can buy them on play.google.com and send them to the device.
Add their devices to your account, and send the apps after purchase

This doesn't prevent them from using his card to buy apps themselves. If their devices are attached to his account, then they can potentially use his account if they know his password or if he stays logged into Gmail on his desktop, etc.

@dotVezz  only „if they know his password” (unless he had disabled prompting for the password for every purchase)

I have the same problem. My kid wants a some small amount to spend on in-app purchases but the gift card is too big an amount. What i am trying to do as a work around is : set up a paypal account and transferred that small amount into it. Then linked my kid's google account to that paypal account with the limited amount.. keeping my fingers crossed that it will work. Google Playstore is frustrating!!

@ale it might be phrased a bit unfortunate, but why isn't it an answer? Summing it up: "You can use Paypal in playstore. So setup a PP account with some pocket money in it, connect it to your kid's account, and that's it."

You get two choices when you accept to buy an app on the device you want to install app on. Pay or send URL for payment to whoever. So send URL to yourself or whoever is going to pay via email which will auto pop up when you select... Send URL... .. I send to my Gmail account then click link on pc or phone and follow instructions to pay . Easy

why is this downvoted?  does it no longer work?

Built-in storage not detected
well I just bought a lenovo s920, at the first time I'm doing a system update and it works fine, then I'm doing another system update S920_ROW_S114_130626_TO_S920_ROW_S117_130815 (79.83MB), I dont know if it's failed or what, after that my built-in storage not detected. I keep getting notification "Damaged Built-in storage" that asking me to format and even I'm doing it, it cant be format.
My Storage setting become like this:
INTERNAL STORAGE
Total Space: 3.62GB
Available: 379MB

BUILT-IN STORAGE (no information)

then when I check spaces with app Freespace:
Cache /cache:         Total space->   123.08MB
Internal /data:       total space-> 1,008.29MB
Preload /preload:     total space->   197.01MB
Protect_s /protect_s: total space->     8.89MB
System /system:       total space->   788.39MB
                                    2,125.66MB

so there's missing around 1,400MB.
I guess this is built-in storage, how can I recover it? and create it again as built-in storage.

The problem was a hardware problem, nothing I could do about it.
I took it to a service center and got the hardware replaced.

HMM the only thing I can think of would be to get clockwork or something similar and format the space and reflash the rom.

where are the free books the kindle app offers?
According to its description on Google Play, in the third sentence, it says that the books are free. I installed the Kindle app and went to the Kindle Store and all the books I looked at so far all have to be purchased.
Where can the free ebooks be downloaded from? Because when I click 'books on device' in the kindle app, it shows none (so I'm guessing I need to download them from somewhere).

Welcome to the Android Enthusiasts! Our site works best with only one question asked per post, so we took the freedom to remove the second one. No need for a separate question for that: Guess the difference between an app and a hardware device should be clear :) Besides, the Kindle tablets are just running Android and the Kindle app, so from that point there's no difference. // As for the free books: Yes, there are some. But the majority is, as you found out, to be paid for.

@Izzy hm okay, interesting. Right yea I thought if you buy the kindle ebook reader then the books will be for free but guess not. And hm okay thanks.

No, Amazon usually makes money via content. But see my answer below: I recommend Moon+ (using the Pro myself): supports a load of different formats, and has many nice libraries pre-configured (including my own bookserver :) If that answers your question, please don't forget to click the check-mark next to the answer, to help others see your issue was solved.

You can try this blog https://kindlebooks.blog/

The majority of books on sites like Amazon, Barnes & Nobles, and the like, are definitly payed for. All of them offer some free books to get you in, but you end up in a "closed ecosystem": you can read them only with their dedicated readers, as they often use their own formats (Amazon) or at least some DRM.
If you want to go for free content, you're much better of chosing an eBook reader app supporting the open ePub format (some exemples include, but are not restricted to: Moon+ Reader, FBReader, and Aldiko. At least the first two already ship with a load of free libraries pre-configured, which they can access directly from inside the app.

This isn't what OP is asking.

When it comes to DRM-free eBook files, you need to purchase that too. Plus, you can push these DRM-free eBooks to your Kindle cloud.

Not quite correct, Sachin. There are tons of DRM free eBooks you can simply download. Just not at Amazon. And let's not go hair-splitting: OP obviously wanted to get "free eBooks" in the first place, and Kindle was just the instrument he thought fitting (keyword: X-Y). And no, I won't discuss that here, unless the OP states it himself :)

From Kindle Store, you can only get popular classics for free. But, Kindle is integrated with many of free eBook providers. For example, on Open Library, you can click Send to Kindle link while viewing a free title (Amazon authentication will be required).
See Amazon's Free eBooks Collection page. It gives you all required instructions to get free eBooks from various sites.

Also, there's no difference if you read a book with Kindle app on Nexus 7 or Kindle eBook Reader device.. except Kindle eBook Reader device doesn't have color display & would provide a very-very long battery life.

There is a difference, if you are prime member, you can only borrow a book on Kindle hardware device. (no option to borron in Android Kindle app)

Device Steadily Discharging While Plugged Into AC?
Question: My device (Galaxy Note 2 running the stable CyanogenMod release) is charging extremely slowly and discharges while it's plugged into AC power.
What happened to cause this and what's happening now:
My device has been wonderful for over a year. Yesterday it ran down to about 10% and I borrowed a friend's charger. It charged up to 100% surprisingly quickly. I then let it drain down to about 3% before putting it on the charger. I came back to see the OS wasn't booted and it was in the charging screen (provided by the BIOS?). I then left it to charge for several hours and it only got about 10%. Then I was using it and it drained down to 0% while it was plugged in the entire time. The icon showed the charging animation and the Battery Status page (the one with the graph) said that it's charging on AC. Every couple minutes the battery loses another percent even while it's plugged in. While in the BIOS charging screen, I left it to charge for about 6 hours and it ended up with only 34% charge. It would normally be fully charged much earlier than this. Plugging it into my computer via USB seems to also make it discharge. I have tried two different chargers (but the same cable for both chargers and the computer).

I fixed the problem by switching cables.
The cable must have gotten a bad connection so the wires dedicated to power could carry less current. You might try bending the cable in a certain direction to get a better connection, but the real solution is to replace the cable.

my phone is also running on cyanogen and unfortunately I have the same problem, this problem may be due to kernel.
here is the solution which I use also.
buy an extra charger of different model say htc  and use this charger till it's charging well, then use the original charger.repeat the procedure if necessary.
it sounds so strange but works luckily.

I normally use a charger from Motorola. I use that one most of the time, but the one that comes with the Note 2 also doesn't work. I see no difference between chargers.

I've also experienced this issue on my Galaxy Nexus running CM10.

Why do I need more than 200 megabytes of disk space to install an APK?
I started to get not enough space errors when updating or installing APKs, but I have 200 megabytes of free space on my internal storage, 2,68 gigabytes on my internal sdcard, and 3,62 gigabytes on my external sdcard. I can't imagine what could use more storage than 200 megabytes in the process of installing a 4 megabytes APK. I'm constantly deleting apps, moving them to sdcard, but I only end up having less and less space remaining. How does this work? I want to understand the inner mechanism of how storage is handled when installing APKs, or in situations that can affect it, so maybe I could write an app to help this procedure.
Edit: I'm using BAM Android on a Samsung Galaxy S2 (i9100).

internal memory space is required to store app data and cache, it doesn't matter much if you move your apps to sdcard app data and cache still gonna be in internal memory.
this problem can be solved by rooting.
if not willing then try some apps playstore which delete cache and auto move apps to sdcard

Galaxy Nexus I9250 stuck on x logo after updating yakju to takju
My Galaxy Nexus I9250 gets stuck on X logo after I updated yakju to takju (4.2 factory images for takju).
How I can fix this?

It would help if you have more details.

You can flash back to factory to save your phone.

Download latest image of your Galaxy Nexus Link.
For example, if you download android 4.3 takju, unpack
You will see flash-all.bat or flash-all.sh. If you're using Windows, run flash-all.bat with your phone connected the PC and drivers installed. And under Linux , run flash-all.sh

How to disable/remove ALL cell functionality
I have a Kyocera Event (Virgin Mobile) running stock Android 4.0.4.
This is only used as a media player for about 90 minutes ONE DAY per week. I am looking for a good way to extend battery life as much as possible as it can only be charged one day a week as well.
Steps taken:

Disabled google account sync
Turned off all location services
Turned "Mobile Data" off

I know it's asking a lot, but I am really hoping to get the battery to last a week if possible.
Any suggestions for extending battery life?

Hot tip: our battery-life tag-wiki, with links to e.g. What can I do to increase battery life on my Android device? and similar questions. Also, some more details might help: Do you need any SIM activity (calls etc.) at all? If so: no chance for 1+ week. Do you have root access on the device? That gives additional possibilities like underclocking, greenifying, etc.

What's wrong with just turning it off for the other six days?

@DanHulme There is a buggy app in use that loses it's configuration if the app gets closed. The users have very limited tech skills and I am hoping to not have to train them to configure this program every time they need it.

When selecting an USB extension cable to extend power cord, what are the relevant considerations?
I want to use USB extension cords to extend the USB power cords for my Android device.  What are the factors that could affect normal charging behavior?  (Consider "normal charging behavior" to be charging speed and long-term effects on the device battery when using only the manufacturer power cord/adapter.)

To be honest I think that its affected by the voltage on the USB port. Some ports are only .5V while others are 1V.

You can also download an app called galaxy charging current that will give you the charge rate of the cable. I know not to go too cheap of a cable because it can sometimes take longer to transfer things.

This cable has received A LOT of good reviews and is made of quality copper and does allow more electricity through to devices!! Check it out :D

Sync certain contacts between two devices/google account
Is there any way of syncing selected contacts from one android device/google account to another?
Consider the following example:
Person A  and Person B share real life contacts, but on their smartphones, each person has to maintain contact details on their own. The data is there, so why do not share this?
The following ideas came to my mind:

Create a new, shared account. All contacts that should be shared are stored in this account. On each smartphone, contact syncing for this account is enabled. This should work just fine on android smartphones. But the contacts of the shared account are not accessible through the web interfaces of the individual accounts!
Use Gmail Shared Contacts for Google Apps. The drawback here is, that this does not work for generic @gmail.com addresses.

Is there any other way (android app, software for Windows/Ubuntu, own contact server, ...) to sync common contacts in a way, that the contacts are present both on android devices and through the normal google webpages?

I asked a very similar question over at Web Apps. The long and short of it is: No, not really. Some third-party services might be helpful.

The approach at http://android.stackexchange.com/questions/60825/transfer-contacts-from-android-to-google-contacts could be used to copy contacts from one to the other and back. But alas, it doesn't automagically keep them synchronized.

Syncing fails after changing Google Apps user's email
A few days ago, I changed the primary email of a Google Apps user from user@domaina.com to user@domainb.com
Ever since doing so, Android refuses to sync using either the new or old email address, but I can still log in on the web using both.
Both domains are controlled by my Google Apps organization, and attempting to reconnect the accounts after a factory reset gives me an incorrect password error.
The device is running Android 2.3.3 if it makes a difference.

Have you tried changing the password, and trying to log-in again with the new password?

I realized last night that since I have 2 factor auth enabled for my account, I might have to generate a new application-specific password in my google account settings.
I generated a new one and successfully synced with my new email using it.

How to install CyanogenMod on my HTC Desire SV
My HTC Desire SV isn't listed as a supported device for CyanogenMod. How can I get CyanogenMod to work on it?
I'm very new to this. So, I could use some help.

Sad to say, CyanogenMod is not working on this model and will not work in the future too.
You could find enough help from communities like xda-developers. One link that might help is: http://forum.xda-developers.com/showthread.php?t=2293155
There are some custom-rom developed by members of xda.
Never ever ever ever forget to backup your stock ROM.
There can be a lot of bugs in these customROM. Common issues found for desire aka MAGNI are screen flickering, wifi problem, sd-card not being detected etc.
I would suggest you to first root your mobile and try installing safeStrap bootloader as your first babysteps before taking a leap into installing the customROM. XDA is the only place where you could get this done.

Nexus 4 not recognised by Windows 7 machine after KitKat update
I have a Nexus 4, which I used to be able to connect to my Windows machine via USB, to test my code on. When I plugged it in, if I tried to run an application on it from Eclipse, Eclipse would tell me that there were no devices, and ask me if I wanted to start a virtual device, unless of course I waited a bit, until Windows popped up a dialog box asking me if I wanted to treat the Nexus 4 as a directory for photos, or audio, etc.
Now however, Windows never gets to the point of showing me that dialog box, so Eclipse will always tell me there are no connected devices. How do I fix this?

I'm not a Windows user. But from similar questions I've read, it might be necessary to re-install the drivers. Are you just unable to access the device, or is it not detected at all? Have you checked your Windows device manager for "unknown devices"? Do you get any popup when connecting it?

Can you see 'Nexus 4' listed in Device Manager under 'Portable Devices'? Mine was initially listed under 'Other Devices' with a yellow warning symbol until I installed the drivers.

Turns out that uninstalling and reinstalling the drivers solves the issue. The strange part is that before I uninstalled the drivers, the name on the driver said it was for a Samsung Galaxy device, which the Nexus 4 clearly is not.

Most likely you'd need a mouse with a scrolling wheel :) Honestly: Have you tried whether it works? What happens if you scroll? As long the answer is not "nothing", you could check with Moony's config and adjust it accordingly.

I have to get a mini USB to USB to test. I don't expect it's in config because what I am asking is unusual. No there's no mouse setting in Moon+. I am asking if there's a software driver/tool which translates mouse wheel movements into swiping commands which Android understands and which any Android software responds to.

How do you know there's no "mouse setting" in Moon+? Sure it's not labeled such, as it's rather unusual (as you already noted). My hope for you is the scrolling event submitted by the mouse might match one of the other events which can be configured. Small chance, but at least it is.

If it's a setting that deals with the mouse, why would it be labeled something that doesn't mention mouse!? You're talking about low level programming. People usually don't use a mouse with Android and among the tens of Android apps I used, none mentioned mouse in any of their settings.

It wouldn't be labeled such because it was not intended for this. Let me explain by an (incorrect) example: couldn't it be the scroll-up event triggers the same "interrupt" as the volume-up key (unlikely, but I wrote it's incorrect)? In that case, wouldn't Moon+ react as if you had pushed the volume-up key? And if so, couldn't you use that for your purpose, substituting "scroll-up" with what's named "volume up" in Moon+?

There's no scroll or mouse setting.

This answer shows that you can capture touch input from the raw device (`/dev/input/event2') to a file, and then play it back whenever you like. You could then automate an event to play back the captured touch input each time you want to scroll.

Are you suggesting I program this? I am not an Android programmer. I am looking for a tool.

If your Xperia tablet is rooted... use an app called Tasker. It is able to emulate to send touch and swipe events to the screen. I have used it in several apps to scroll the screen up. Of course you can use Tasker if the device isn't rooted, but I'm not sure if you can send shell commands.
In Tasker, create a new task, Action category CODE--> RUN SHELL--> input swipe X1 Y1 X2 Y2
Check out this link: http://www.pocketables.com/2013/07/how-to-emulate-touch-input-using-tasker-and-root.html
You can also use Tasker to send button events to emulate a directional pad. Just send x amount of clicks in order to scroll the appropriate amount of the screen.
Now you just have to figure out how you want to trigger that task to run.
If this works, let me know!

And how to bind that to the mouse? AFAIK there's no way to tell Tasker the mouse input directly, but I might have missed that.

Can I downgrade from Kitkat to JellyBean on my Moto X?
I have a stock (non-rooted) Moto X that 'upgraded' itself to Kitkat recently.  Is it possible for me to go back to Jelly Bean?
(Deliberately leaving out the reasons since that's not the point of the question.)

possible duplicate of Can I downgrade to an earlier version of Android after installing an OTA update?

I'm not VTCing this question, because I think the steps for downgrading a Moto X will be different from the steps for downgrading a Nexus device.

The full guide can be found here but i've included the steps below in case that page is not available.
NOTE: All of your personal information, data, accounts and so on will be deleted so make sure you have a backup

On your computer Android SDK must be installed: learn how to install Android SDK on Windows, or learn how to set up ADB on MAC OS X / Linux.
Also, on the same computer the Moto X drivers must be installed.

Download the RSDLite app from here.
Save the file on your computer.
Also, install the program.
Get the Moto X stock Android OS from this page.
On your computer, unzip the downloaded update file.
Then, from the folder that will be created right click on the file
  with .XML extension.
Select “open with” followed by “notepad” or any other XML editor
  from your computer.
Find the following string and delete it: “step operation=”getvar”
  var=”max-download-size”.
Save and close the notepad window.
Open the RSDLite program on your computer.
Take your Moto X and connect your phone with the PC via USB cord.
On your PC now open a command prompt window (start -> run -> cmd).
On the cmd window type: adb reboot bootloader.
Your phone will be rebooted in fastboot mode.
From RDSLite, click on the three-dot browse file button and select
   the .XML file.
Up next, click on “start”.
Wait while the process is running on don’t press anything else.
When the firmware is successfully installed you will be able to
   unplug the USB cord.
Good; now reboot your smartphone.

The first Android version of the Moto X was Android 4.2.2 Jelly Bean. As a consequence you can downgrade your Moto X until Android 4.2.2 only, not Ice Cream Sandwich (Android 4.0.x).

This is not an answer, would be best made as an edit or comment.

Why isn't it an answer? It may be wrong (because OP is confusing - "ICS" in title, and "Jelly Bean" in body) but it is a valid answer.

I am using samsung note3.I am using wifi in my office.For some couple of days wifi connects but no internet access
I checked lot of forums and discussion but could not find any solution thus posting this for support. I tried lot of solutions given in forums but didnt help.
in mobile - wifi detected password accepted but cannot do anything relate to internet. Shows no access.in Google playstore it keeps loading loading and loading and in end says no access. Cannot sync gmail / google talk . Cant FB.
In Short in Mobile cannot access internet even though wifi is connected and gives xcellent signal.
It worked when I brought the mobile, it worked for a month and all of a sudden without changing any settings it has stopped almost for last 15 days.
I thought it was something with my mobile - I took my mobile to friends and relatives place and also to mobile shop..everywhere without changing any setting in mobile it connects with their wifi, also get internet access and can do everything.

Seems like your office network team had block your mobile from accessing internet. There is nothing to do with your device issue.
If your device connects to wifi excepts your office wifi then this is not your device issue. If you want to start it again contact your network team.

Might be,But probably what would have they done?

Blocked your device in the firewall, using a MAC filter... there are many things a network admin can do. Have you tried to browse the intranet (not internet, but your company's local pages)? If that works, it's rather the firewall setup to not let you out. A MAC filter wouldn't let you in at all (i.e. you wouldn't even get an IP address via DHCP).

Thank you for the information..I tried downloading a film...that might be the reason if they have blocked..let  me know is there any option to get rid of this issue other than contacting network administrator?

Expand RAM on Micromax Canvas A76- Android 4.2.2
I want to use my SDcard to expand my RAM. I am falling short of RAM memory and due to which I need at least 500 MB more RAM space. For this, I have a class10 8 GB microSD card. Can anyone suggest how do I expand my RAM on my device. If any efficient apps are available in the Play Store, please let me know.
P.S. I am a new Android user.
Suggestions and help are always welcome! :)

Welcome to the Android Enthusiasts, Abhinav! First suggestion: Make the title and the text of your question match. What are you after: rooting your device, as the title suggests? Or "expanding your RAM"? → Assuming the latter, make that the title. If it turns out it requires rooting your device (which it certainly will), make that a second (separate) question (SE sites are Q&A sites, which work best using one question per post).

Thanks @Izzy! Point noted! I guess I have to go for rooting my device in either way. But, can you tell me if creating swap spaces in my memory card will really help in easing the burden over the RAM?

That might depend. Helpful resources: questions on swapper / questions tagged "swap". Studying those, you might get an idea about before/after conditions as well as possible side-effects.

You cannot expand your RAM to SDcard!
Instead you could create swap space in sdcard.
You could use applications like Swapper from google play store. The device must be rooted to do that.
Swap space may not be as fast as RAM.

How will creating swap space reduce burden over my device's RAM? If possible, could you please explain the usage of this swap space in context of Android environment?

For that, you also might wish to see Why don't most Android devices have swap area as typical OS does?. It might help in some cases; but there's most likely a reason why it's not "built-in" by default.

Ignore crack in Android screen (and entire front panel) or take some action
My Galaxy S3 was in my jeans pocket when I leaned over to pick something up that I dropped under the table. A few minutes later, when I took out my phone, I saw a long diagonal crack from one side of the phone, straight through the middle of the screen area and all the way to the further edge of the phone.
Thankfully everything still works.
My question is, is there anything I should do about it - i.e. replace the screen, layer it with transparent tape - or just leave it and everything will be fine (i.e. it can't get worse)?

Lots of screens are cracked and they still work.  Mine has had two cracks in it for over a year.  At first I put thin non glossy mending tape on each crack.  It was unnecessary no glass sticks out on it though I can feel them with a fingernail, so I just leave it bare.  For anything worse and still working you might use a screen protector, which I'd certainly do if the alternative was getting cuts on my fingers.  Would be interesting what your experience actually was as has been several months since you posted.

Good idea. Shortly after I wrote this question I placed a screen protector over the screen and it's worked completely as normal since then.

What is master key vulnerability in android?
What is master key vulnerability in Android? From looking at a few different sites, I understand that it is bypassing the authentication provided by signing of apps.
How can I detect an app is vulnerable to master key vulnerability. Can anybody please give an example?

You've already described correctly what that "master key vulnerability" is about. If your only source for new apps is Google Play, you're most likely on the safe side; danger from this seems to be restricted to side-loading via unknown-sources.
However: If you want to check whether your device is affected, there are several apps out there which promise to do this. E.g. Belarc Security Advisor describes itself as checking for several hundred security flaws known on Android (including the master key). If the check is "positive", there are also fixes available, like Master Key dual fix or the Master-Key Security Patch (a module for the Xposed framework).

Nexus 7 Share Dialog No Longer Showing Up After KitKat
Before the KitKat upgrade, tapping "Share" in apps would bring up a dialog that lists all apps that you can share to. After upgrading to KitKat, tapping this button only copies the link to the clipboard.
I should note that this only happens on some apps, like these listed below:

Chrome
Bacon Reader
Hacker News 2
Trello

Is there a way to bring back the old functionality?

That's a known bug with Kitkat, not only affecting the Nexus but other devices as well. We discussed that on chat lately. A work-around is using an app like AppChooser, which replaces the share menu. As a side-effect, it even gives you several improvements above the built-in share menu, as e.g. the possibility to chose between grid and list display, or have the list sorted alphabetically versus last-used (where the latter would have your most frequently used share-targets always on top). You can even hide apps you don't want to see in the share menu (and make them visible via the "show all" button).

AppChoser (source: Google Play)
The only alternative I know of is Andmade Share, which offers comparable features.

Cannot detect wifi
my Samsung galaxy tab 2 (7.0) cannot detect my home WiFi. but neighbors WiFi can be detected. please help me. but all my phones and laptops can detect my home WiFi.

Try changing the channel that the wireless is hosted on. I've had this recently with two different devices (one android) where my wireless did not appear in list of available SSID's. In both cases it was in the 5 GHz spectrum and moving my N to a different channel fixed the problem. Apparently certain driver don't implement the full spectrum properly.

It's not always a driver problem: not all channels are legal to use in some countries, so devices specific to your region will know which channels are legal and only use those channels. Devices from different regions will have different restrictions.

Good point! I was assuming all devices were from the same region, but I guess a number of my devices have modified firmware so I might just be finding the hard edges.

I think you should contact your home wifi broadband for assistance.If you already did this,I think the problem is in your own tablet

SGH-S730M SAMSUNG DESCOVER
i have my sgh-s730m Android phone my problem is my screen is being locked it appears EMERGENCY CALL can you help me on how to solve this kind of problem?

I don't know your device by the "technical name". But usually this indicates that there's either no SIM inserted/detected, or you didn't unlock the SIM (it's usually protected by a PIN), or the SIM is locked due to entering incorrect PINs. Can you provide some details on these facts? Does any of them match your current state?

You should call an operator to fix this kind of problem

Why? And what operator? Isn't there anything the OP can try before that? What is "this kind of problem", and what stands behind it? See my comment on the question itself: there are some things which should be veryfied before contacting service. The solution might be as trivial as putting a SIM card into the device.

I think the problem is already on the phone.I cant give what is the solution for this problem because I don't know what happened before this situation came up.In that case I suggest that you should take a test.Insert a new sim card or use another sim card.If you did this one and the same problem occurred again.I guess the problem is on your phone.OR when you did this and this problem didn't happened then the problem is on the sim card itself.

That should have been part of your answer :) Especially the example procedure of trying with different SIM cards. Would you mind to [edit] your answer, and include that part, so it's easier to make out? Thanks!

Find Proxy IP address used by Android app
I use the "Proxy Browser For Android" app on the android platform, developed by Abhinav Singh.
It uses a proxy to enable the user to browse anonymously.
I really wish to know the ip address used by the app.
My question is: How do you closely monitor the internet traffic on an Android ?
I am an Android developer, so I use ADB to connect Android to the pc, and issue commands to android from the pc. Is there an ADB command that I can use to see internet traffic or even get logs etc ? If not, then, is there an app for that ?

The easiest way to monitor Android internet traffic is to connect it to a Wi-Fi network and run Wireshark on the router. That way, you can do whatever you like on the Android device while watching the packets go past on the Wi-Fi router.
An on-device solution can be less convenient, because you have to do the activity you want to monitor, then switch to the monitoring app to see the results. In addition, you need to have root on the device to monitor other apps' network traffic. In some cases this can change the behaviour of the app you want to monitor, though I don't expect that'll be a problem for you. Network Log is an open-source example of an on-device network logging/monitoring app.

Thanks a lot, I've found this to setup wiresharp on wireless lan,http://wiki.wireshark.org/CaptureSetup/WLAN , but could you perhaps explain it in an easy way ?

@Dv_MH That would go a little beyond the scope of this site. We try our best to help out with specific Android questions, but rewriting the existing documentation for a non-Android tool is going a bit too far. I suggest you try it out yourself, and if you get stuck, see if anyone in the Wireshark community is willing to spend their time on this.

Meaning of version code name on Google Android ROMs?
While watching this, I wanted to find out the meaning of version code names like KRT16M? Is there any documentation for decoding what it means, or is it just a random hash code?

Per this:

... the first letter is the release family (e.g. KitKat), second letter is the branch code (Release or Testing), and the next three characters indicate date code (quarter beginning in Q1 2009, day number within quarter).

I know the K stands for KitKat, but not sure what the others mean. You might want to check the Codenames, Tags, and Build Numbers documentation for more information.
KRT16M would refer to android-4.4_r1, the Initial KitKat version, Nexus 5 (hammerhead).

When using "voice typing", how can I capitalize a proper noun?
When I press the speech-to-text button on my keyboard, I can dictate some text. Say I have a pub called the Red Lion that I want to mention. How can I get it to type "Red Lion" instead of "red lion"?
Letting it enter "red lion" and going back and editing it with a normal keyboard is very slow, because the popup menu of alternative transcriptions makes each edit take an extra click.

Related to this is: How to make voice typing use punctuation.

@ScottSeverance That's easy: you just name the punctuation mark you want to type. It insists on calling a full stop "period", and only works for the most common punctuation marks, but it's fine for short messages.

As of 2019 this still doesn't work reliably for me, either for punctuation or capitalization. Wish there was a better solution.

Picked up from this Ruben Roy answer in a more recent question:
You can use this comments to start and stop typing with capitals with the Google voice typing Android keyboard.
"Caps <word>"                           Type with an initial capital
"All Caps <word>"                       Type in all uppercase
"Caps On"                               Start typing words with initial capitals
"Caps Off"                              Stop typing words with initial capitals

Your first link is not for the Android version of voice recognition. Notice the keyboard command references.

hit or miss m afraid
Google voice to text is most likely to type the words "capitalise" rather than take the instruction

@freda Nobody even mentioned the word "capitalise", so there's no point complaining that it doesn't work.

None of these are currently working using google keyboard.

How do I show the upload status in the notification bar?
I have an HTC One.  I recently went to Settings --> Apps and disabled "Show Notifications" on one of the apps listed that prevented showing the upload status of whatever I upload (Facebook video, pictures, etc.) in the notification bar.  I can't remember for the life of me which "App" this was - how do I re-enable showing uploads on my notification screen?  I am using 4.3.

Most apps, if not all, have the Show Notifications checkbox. I suppose you'll just have to go through all your apps, and see which one was unchecked and check it again.

Read content of .thumbdata file
I don't know how I managed to delete all my pictures and unfortunately, it took me a few days to find out they where gone. I tried to recover them with DiskDigger, but I didn't have much luck with it (most of them were damaged).
I found 2 400Mb+ files called .thumbdata in the DCIM\.thumbnails folder and I was wondering if there is a way to extract data/thumbnails from it.

It contains 96x96 pixel versions of your photos. The file is simply a concatenation of JPEG files. You can split it into individual JPG files by searching for the signatures indicating the start and end of a JPG file, i.e. the two bytes FF D8 for the start and FF D9 as the end. If you can transfer the file to your computer and you can access Python, the following Python code will extract the files (name the file thumbdata3.dat):
#!/usr/bin/python

"""extract files from Android thumbdata3 file"""

f=open('thumbdata3.dat','rb')
tdata = f.read()
f.close()

ss = '\xff\xd8'
se = '\xff\xd9'

count = 0
start = 0
while True:
    x1 = tdata.find(ss,start)
    if x1 < 0:
        break
    x2 = tdata.find(se,x1)
    jpg = tdata[x1:x2+1]
    count += 1
    fname = 'extracted%d03.jpg' % (count)
    fw = open(fname,'wb')
    fw.write(jpg)
    fw.close()
    start = x2+2

The program will save the files with the names extractednnn.jpg, where nnn is a number.

Perhaps someone also knows how to extract the images from thumbdata5 files... this script gives some results, but they are a bit broken. (And the thumbdata files are big, but the extracted files make up much less in size.)

@imz--IvanZakharyaschev : The thumdata file is a sparse file. Open it with hexdump. While the file is large, there aren't many thumbnails in it.

Retrieving contacts from Nexus 4 with broken screen
My Nexus 4 is recognized by ./adb devices when connected via USB. Also USB debugging is enabled. Unfortunately the device isn't rooted so pulling the contacts db file doesn't work as I don't have access to the appropriate directories (I think). How can I retrieve my contacts in this situation?
Note I never synced my contacts with Google.

Please take a look at similar questions: I Need Help Getting Contacts from Broken Android! / How do I backup data (SMS/contacts) from a device with a broken screen? Both of them have answers which might solve your issue as well. If not, please [edit] your question and let us know how your situation is different, so we can find another way to help you.

if you got airdroid working you can use your pc screen.
https://play.google.com/store/apps/details?id=com.sand.airdroid
you can get the app installed through google play online.
is your screen broken meaning you cant see it, or it also doesnt accept input?

Thanks for the info. My screen was broken and would not respond to touch events. However the display still works. The solution I went w/ was issuing adb commands to open the contacts app, scroll up/down, view contact etc and just wrote down the info for each contact.

alternative ways to take screenshots on Galaxy
When there is a rubber-protector around the phone or the tablet, I find it extremely difficult to do a palm-swipe-to-capture action,  to get a screenshot.
That's due to the fact that the raised edges of the screen protector prevents my palm to completely flush on the surface of the phone.
Is there a way to get the screenshot any other way and a more convenient way?
Or an app that will do that? matye thru share via route??

http://android.stackexchange.com/questions/1759/how-to-take-a-screenshot-with-an-android-device has 16 answers. I would assume at least one will be usable.

Volume down and power button, or else home button and volume button. That's how most galaxy phones work, but a google of it shows tons of videos and descriptions for each Note model

changing the "hi galaxy" phrase. is it even possible?
Every once in a while, my note 3 wakes up on its own thinking somebody said "Hi Galaxy" and gets itself into the listening mode to start capturing what it hears from that moment on, then submits to Google for a search!
Boy! I had a few situations and eventually I had to turn off that awesome feature.
Is there a way to change this "hi galaxy" phrase to something less likely to be confused?
Can I personalize it?
Something like "ok Samsung, wake up now!" or "ok note 3, wake up now" etc...
the longer the phrase, the less likelyhood for an unintentional match, I assume.
Also, being able to personalize this phrase will prevent other people's getting your way... Imagine, the guy in the bus says "Hi galaxy" to his phone and all the galaxy devices in the bus within reach wakes up. LOL!

Open the S Voice app, and open its settings. You should be able to change it via Set wake-up command.
Here's the setting from my Samsung Galaxy S4:

no geffchang. that's a boolean setting. you'd think that would be the place to do so. but unfortunately, it is not.

@AverageJoe Uploaded the correct screenshot.

Wow! I can get there only when I take the path from "s find -> set wake-up command" route. Interestingly, for the note 3 I got (at&t), the setting you describe is not available; so "S Voice app -> open its settings" does not allow me to see "set wake-up command". but anyway, thanks to you, I used the s-find and get to that jem!

got it.:) Please see this link.  There, somebody else is also  making the same point that this setting is missing on note 3: http://support.t-mobile.com/thread/56280 also, even if I were to do the "sfind->set wake - up command", I'm unable to configure the function 2,3 and 4.  I wish there was a way to video capture the screen.

So, you were never able to change the command? I think you also misunderstood my previous comment. Although my answer helped you, it did not fix your problem. Instead, your solution fixed the problem. So I suggest adding your solution as an Answer (instead of it being just a comment), and accepting it later when you are able to (I think 2 days later). :)

Well, the fact of the matter is neither of our solutions fixed it. The problem is rooted in the note3 itself. Other samsung devices do not suffer from this. My method was a hack to get to the setting that you brought up (the Set wake-up command setting). In note 3, the only way you get there is by going thru the s find-> wake. But even that yields nothing because assigning various phrases are disabled on note3. In other words, your 2nd screenshot is available but disabled. It beats me as to why Samsung took this approach. I will keep your answer as still the one cause that's the closest.

The "Set Wake-Up Command" you mentioned (via  S Find-> wake), is just a help file on the actual commands. If you go to the following, you can change what the Note 3 responds to on the lock screen:
Settings -> Device -> Lock Screen -> Wake up in lock screen -> Wake-up function X
(Note this is just the lock screen when the phone is set to swipe mode, not while it's asleep. Neither does this affect S Voice, but you can still do some cool things.)

my buck stops at settings>device>lock screen.

cause right there, I see, Screen Security & Screen lock (none) and nothing else. You sounded like I should have seen Wake up in lock screen option.

The voice commands are part of the screen lock settings.  Touch the"screen lock" setting and it will take you to the"screen lock" settings which include "wake up commands". Once you check/turn on "wake up commands" you will have a new button below that should be called "set wakeup commands" or something similar.  I have a Galaxy S4.

How to remotely backup folders on stolen Android?
Most Android anti-theft apps can backup photos and text messages, but is there any app that can be installed through the web version of Google Play that can give me access to my folders and files to backup online if the phone is connected to WiFi?

The lost-phone tag you've used might include the key. Please follow up to its tag-wiki, which includes a few helpful links.

If you have a Dropbox account, you can use Dropsync to select which folders you want to sync to the Cloud.
I'm sure there are other solutions, but this is one thing you can consider.

Thanks geffchang, but how about a stolen phone that doesn't have DropSync on it?

@Qattaj I can't help you there, since I don't know. All I know is that some anti-theft apps let you WIPE / format the phone remotely. But if you needed an app to use AFTER the phone was stolen, I think that's too late. Anti-theft apps should be installed before the phone is gone; the same goes for Dropsync.

If you synchronized your device with gmail account, then login on your gmail, and check there for data.

You can’t and you shouldn’t be able to either. Lost means lost. It would be a huge security vulnerability if you could arbitrarily extract files from the device remotely. The time for backing up has come and gone.

Why would it be a security vulnerability? The device has an authorized Google account and OP wants to use the same account to remotely install apps in his device to get hold of certain data. What's wrong in that? That's the feature of Play Store.

View local website on an Android device
Web developer here.
I have two devices, a Samsung Galaxy S3 & a Samsung Note 10.1. I have developed a website which is running on PHP and I would like to view my website on these two devices without having to upload it to an online server. My local server is a WAMPSERVER.
I've heard that you could use Wi-Fi and connect to my PC's IP address however my wifi signal is very weak (I use a desktop upstairs, router is downstairs) so I would like a setup that requires me to physically connect my devices to my PC through a USB cable. Is there a way to do this?
Thanks in advance! :)

That's called reverse-tether. I took the freedom to attach the tag to your question. You can follow this link to see other questions (with answers) discussing this, and extract a solution fitting your situation. So much in advance: reverse-tether usually requires root access to the device. But AFAIK there are also USB-Ethernet adapters (I've just heard about, but have no experience with those).

Thank you @Izzy! I feel i'm on the right path to something.
I've tried typing in my PC's IP address however I get "Forbidden You don't have permission to access / on this server"

I don't know where you're "typing in" the address, so I cannot follow. But have you checked the link from my previous comment? Anything matching? Any success? My recommendation is starting with those, and then reporting back by either answering your own question (if you succeeded), or [edit] it with what you've tried and where you're stuck.

@Izzy, I'm getting internet from my PC to my phone so I know theres a connection happening.
Now, I want to be able to view my website on my phone. I've tried typing my PC's IPv4 address into my phone's web browser and the message I receive is "Forbidden You don't have permission to access / on this server". I tried typing the wampserver's IP address and I get no luck from that.

Ah! Now that get's clearer. Guess that part is rather an issue for Server Fault. Check your web server's logs for why it's rejecting you. Maybe it only accepts connections from localhost, or something alike.

Not sure how much help this is, but I've had success using the reverse tethering solution with IIS, so it must have something to do with your server. With IIS I connect using the Ip 192.168.0.0:port/{path of directory within IIS instance}
Hope this helps

Samsung Galaxy s3 can't edit contacts much
When I click on the 'edit' icon for a contact, the only options I get are to change their name, phone number and email address. The default profile picture disappears so I can't change their picture. Can't add additional information. Can't favourite them. I know you can go to favourites, or image gallery (and pick an image), and then pick a contact to allocate (as a favourite or the image), but my contact list turns up empty when I try this route. Even though I have contacts. Has anyone else had this problem or know how to fix it?

Are you using the stock Contacts app, or a 3rd-party app?

Excuse my ignorance, if by stock contacts app you mean the one that comes with the phone (orange phone book icon with white person outline), then that one :) thankyou

Figured it out - the contacts were saved to my SIM card, not my phone. I had to import all my contacts from my SIM to my phone and then I was able to edit them fully :)

Can't make gallery photos lock screen wallpaper (Samsung S3)
I can only make the preinstalled wallpapers the wallpaper for my lock screen. I can choose an image from my photo gallery, select and crop it and then save it, but the lock screen just stays the same. Anyone know how to fix this?

I have a Samsung Galaxy S4, but see if you can set a common wallpaper through a similar path: Settings > My device > Display > Wallpaper > Home and lock screens.
UPDATE 2013-12-06: Another solution you could try is to clear the default app for pictures. If it's a 3rd-party app like QuickPic, go to your phone's Application manager (via Settings), select the 3rd-party app, and do a Clear defaults.
Afterwards, open the Gallery app (not a 3rd-party app like QuickPic), pick a photo, left-soft-click to open a menu, and click Set as. You can pick either: Home screen, Lock screen, or Home and lock screens. Source.

Thankyou for your advice. Unfortunately neither the home or the lock screens change when I try to do it this way. The home screen will change if I change it on its own, but the lock screen won't budge :s

@Chelsea (1) Maybe you could try setting a photo from a gallery, or a live wallpaper. Then, restart and try it again? (2) Did you install any 3rd-party lockscreen?

Thanks for the suggestion, unfortunately it didn't work. I did not install any 3rd party lockscreen

@Chelsea Do you have another gallery app installed? Like Quickpic perhaps?

@Chelsea I updated my answer. See if that helps.

Hey! Sorry didn't get back to you sooner. Clearing defaults for the only picture viewer I have (Gallery) didn't work, but resetting defaults on all my apps did, so you put me on the right track :) thank you very much!

system.img file is missing after building Android source
I am attempting to flash a modified Android build to my Nexus 7 tablet.
I am following this tutorial from Google, and using the specific build commands found here for my device, full_grouper-userdebug.
With the device in fastboot mode and connected to the PC, I run the following commands:
$ . build/envsetup.sh (Initialize build environment.)
$ lunch full_grouper-userdebug (Configure the build for specific device.)
$ make -j8 (Build the source.)
$ make fastboot adb (Build fastboot and adb.)
$ fastboot -w flashall (Flash build to device.)
At this point, I receive the following error:
error: cannot open '~/<source path>/out/target/product/grouper/system.img'
When I issue a find command, nothing is returned:
$ find ~/<source path>/ -name system.img
$
Why does the file not exist? Without it, I do not know how to flash my modifications. Any ideas?
I am using Ubuntu 13.10.

Can you please direct me to a more appropriate place to ask?

OK. I asked there first, and was referred to this site...

You might want to look into Where can I ask questions that aren't Android Enthusiast questions?

It looks like the build did not complete successfully. Run make again. It should try to resume from the point the build failed, whereupon it'll encounter the same error again. Probably the error message will tell you what went wrong: possibly it's a problem with the software you need to build the source, or likely the way you've "modified" the build has caused the problem.
If you can't work out yourself what the error message means, then our sister site Stack Overflow will be able to offer specific help if you tell them the message and your situation.

wave hand & lock phone automatically
Is there any way to lock my Samsung Quattro (running Android 4.2) just by waving my hand upon it?

Guys, "How do I do X?" is not an off-topic subject. "How do I do X? Is there some app?" is not off-topic either. If you don't like the word "app", just leave it on the side of your plate.

You could use automation apps like Tasker to use proximity sensor to do this. But the problem will be that it will get locked/unlocked at unwanted situations (like while in bag or pocket).

Rule of thumb: if "is there an app for" can be re-phrased to "is there any way to (achieve this)", it's most likely on-topic. I just did so with this question.

I cannot promise that any of these solutions work on your device, but there are several apps listed which seem to be able to achieve this, as e.g. Air Gesture Control or Wave Control. Just try a search for "air gestures" on Play Apps.
Note: my links go to AppBrain, as that site is not limited to 16 search results. Being an alternative front-end to Google Play, you still can install your findings from the latter. AppBrain even offers Google Play links for each app.

After Droid firmware 4.3 update, no predictive text
I updated my droid firmware to 4.3 on Friday and had a fairly easy install ..except that my predictive text is missing in action. The setting is switched to ON (Galaxy S4 by the way) but the ribbon that usually appears above the keyboard with autocorrect suggestions is no longer there.
Can anybody help me please? I want my ribbon back. :)

What keyboard are you using? Some types of text box do not allow predictive text, for example: password fields. There are modules in Xposed framework (rooted devices only) that work around this issue. Is it completely gone from all text fields?

Hi @RossC, I'm using the standard Samsung Keyboard. The predictive text is missing from all apps that use the keyboard. Every single one. I wonder if there's a way to update the Samsung keyboard.

could you download Google keyboard from the Play Store (it's free) and see if you have the same issue. I'm loathe to recoommend the usual 'factory reset' option initially as you'll lose a lot of data. I updated my S4 to 4.3 and didn't have this issue myself. I've since rooted and put other ROMs on it. Maybe see if it is an input issue or the specific keyboard first.

@RossC, I think you could post that suggestion as an answer. I certainly think it's a fitting resolution to this issue.

I had this same issue. In my case I had a bunch of words I didn't want and didn't realize there was the options to reset the learned words. Therefore, I used the system's application manager to clear cache and data. After doing this it broke the ribbon. No matter what I did I could not get it back.
I tried just about everything, but the only way I could get it back was as follows: (please note I am rooted)
1) Switch default keyboard to something else
2) Load "Titanium Backup!"
3) Browse to the "Samsung Keyboard" app and "Wipe Data!"
4) Switch back to Samsung Keyboard and the ribbon is back! :)
I'm not sure why Titanium Backup!'s "Wipe Data!" worked better than the "Clear Cache/Clear Data" from the Android settings menu. I'm wondering if clearing the data from the Android menu a second time would have worked.
I just wanted to post this information to help whoever has this issue next. It definitely can be fixed by wiping the data for just Samsung Keyboard (no factory reset needed). I just didn't narrow it down to if you need Root access, and if you need to use Titanium Backup!
Good luck!

Sadly I ended up wiping my keyboard cache + data: net result is a phone that won't start. Apparently this is a good thing because they are now replacing my battery and screen for free plus upgrading the software :)

The thing that worked for me was downloading and using English (UK) as default.

Try Settings > Language and input > Samsung keyboard. Click the Settings icon (right side) > Predictive text, and turn it ON.

How to find out if my mobile data is working or defective?
I installed CyanogenMod 7.2 stable on my Samsung Galaxy Ace before, but it seems mobile data wasn't working. I decided to download the latest nightly build (2013-03-01) but still the mobile data doesn't work.
What are some ways to troubleshoot/test if my mobile data is working? Note: it was working before on stock ROM.

I found the problem: Roaming was active. That's why mobile data wasn't working.
Simply disabling roaming fixed the issue.

Put G+ back on share menu?
It use to be when I went to share a photo on from my Droid, a little menu would pop up with Facebook, G+, GMail, text messages, and more.
After what I think was an update, that menu changed.  G+ seems to have been removed and something called "Photos" has replaced it.  Tapping "More" lists a lot more apps but none of them are G+.
Choosing photos does not create a post on my G+ stream.  Instead it uploads the photo to some weird holding place that can only be accessed from the G+ web interface.
How can I get my G+ app back into the share menu?
Thanks in advance.
P.S. I have tried Andmade Share. It involves way too many taps.  First after tapping share, you have to tap more. Find Andmade share in that list and tap it.  Then Andmads Share shows an even longer list of apps.  From there you have to scroll to find G+.  Not the simple, tap share tap G+ post.

If the list you get after clicking "More" is too long, it scrolls. Could it be that you simply need to scroll the list to see Google+? If that's not it, does Google+ still show up in the app drawer (the list of all apps)?

Also, instead of Andmade, take a look at AppChooser. My personal preference. And besides: the "Photos" app is part of G+, afaik. Looks like they want to integrate the Galery app into G+ like they did the SMS with Hangouts.

It isn't in the More list.  I've scrolled.  It clearly was replaced by this Photos thing.

wireless crash in android 4.3 and 4.4
after updating my google nexus 4 android version to 4.3 , my wireless get crashed. in just one way. if it was on and i turn off my screen, and it goes in sleeping mode, after turnning on my screen it just crashed. always off , and in just two ways i could fixed it. restart or flight mode. sure i used flight mode. but it wasn't the big problem. the big one happened in version 4.4 . after this happend i can't fix it even by flight mode. just restart. now is there any solution for that?

it seems my problem was in my battery saver app (in this case 2x battery). i read a question in this site couple days ago. the problem of questioner was like me and he/she answer it, and said problem was from battery saver app. i think if i disable this option (wireless saver) it goes well. but just after disabling the hole app it fixed. for now i check it and i didn't have any problem.
p.s: i really forget the title of that question or link of it. if i find that, i set it here for others.

If that solves your problem then you can put it as an answer (and accept it) which will inform others the question has been solved.

ok. so i just copy and paste my answer. tnx.

multiple user for Android
I have a Le Pan Mini with Android 4.2.2. It's obviously not the greatest device but it's what I could afford and most importantly it has 4.2 which is supposed to support multiple users.
But it doesn't.
I am sure I have the 4.2.2 but users doesn't pop up in the settings menu. Any ideas on what I should do?

In Android 4.2, only tablets support multiple user profiles, not phones. This means it's up to the manufacturer to enable multiple users when they set up Android for the device (what's called system integration). Since the Le Pan Mini is a tablet, they should have turned on this support. You should report this bug to the manufacturer (and let us know what they say, to help future visitors).
It's sometimes possible to change this using a customized, unofficial firmware, but that relies on having a community of knowledgeable users who can do the work necessary to create a new firmware image: this is very hard without the manufacturer's support. Since your device is not a mainstream one, it's unlikely there are enough interested people with the necessary skills.

Get root and then install the Xposed framework:
http://mdc.gd/xposedfw
And then the MoDaCo Toolkit:
http://www.modaco.com/topic/361634-xmod-modaco-toolkit-for-xposed-framework/
Once everything is installed, and the MoDaCo module is activated inside Xposed framework (you need to go back into it once it's installed and running and do this), you can then enable multi-users in MoDaCo (as well as many, many other hacks - BE CAREFUL!).
After a reboot, go into your Android settings and there will be a "Users" section. Enjoy!
This all works perfectly on my Son's similarly cheap Ondo V701s. I have the primary account (which gets root access and other goodies), he gets a pared-down desktop with mostly games.
One thing to note; my "Onda Desktop" refused to function on the second user's account and I installed Nova, removed the default launcher. I'm guessing other Chinese tablet manufacturer's will have similarly flakey custom launchers. The Standard Android 4.4 launcher also works well (I briefly played with GoogleHome.apk v0.9.6.886092).

Disable all Samsung Stylus pen gestures (e.g. Samsung Galaxy Note)
When I hold the side button of my Samsung Galaxy Note's stylus pen pressed, it doesn't draw anymore but starts interpreting any stylus movement as a gesture (e.g. "go back", screenshot). Is there any chance to disable all gestures? Background: I have a drawing app that allows changing drawing mode when I hold the side button pressed. Until now pressing the button prevents the stylus from drawing but executing gesture actions.

Can't surf from PC when using Android as hotspot
I turned on mobile data and hotspot in my Samsung Galaxy Ace (On a Philippine carrier called "Globe"). I can surf websites just fine directly on Android.
Now, I connect my PC to Android's hotspot, it connects but it can't surf or ping websites.
It used to work before (used it some months ago) but now it doesn't. What could the problem?
Edit:
ipconfig screenshot:

This could be a local networking issue. Can you get the network configuration info from your PC? If you're on Windows, could you update your question with the output of ipconfig from a Command Prompt while connected to your hotspot? (Please edit your question with the information)

What carrier is the device on?

@dotVezz updated with ipconfig

@Compro01 This is a Philippine carrier, Globe.

I had the same, although intermittent, problem recently. Whilst it would be OK for periods of time, my connection would drop and be unable to connect to sites, whilst the phone connection was still OK. In the end I put it down to the fact I was still connected to my wired LAN through which I would normally connect to the internet (my main broadband connection was down for a few days, hence why I was tethering via mobile). If I disconnected completely from my LAN (which wasn't desirable) I would regain the mobile connection.

@w3d I see however my LAN is completely disabled when I'm connected to Android.

Out of curiousity: Could you post the output of the following in Command Prompt? ping 8.8.8.8

@dotVezz Timeout 100% loss. But, interestingly if my manually set my WiFi Adapter to use 8.8.8.8 and 8.8.4.4 as DNS servers, I can ping 8.8.8.8 and 8.8.4.4, however still not browse or ping any sites.

If you are using the built in Wifi Tethering in Settings, then Android might have automatically misconfigured the iproutes.
You can try clearing the data on the tethering app and settings to refresh the configuration. Open Settings -> Applications -> click Settings -> Clear Data.
Same procedure for the tethering app, Open Settings -> Applications -> click ">your tethering app here< -> Clear Data
and to add, I'm also a Globe/Sun subscriber :D

Try to ping DNS eg google DNS "ping 8.8.8.8 -t" if it replied, then your problem might be browser specific. Check if you do not have proxy settings set on your browser.
If it does not reply, make sure you do not have a VPN software installed on your Android device, Tethering will not work with VPN installed on Android. Also make sure you do not have active VPN on your PC too as this will change the default route of the network.

Try giving DNS configuration manually. It solved this issue for me.

Apparently some mobile operators block tethering by checking the browser "User-Agent" when you request a web page...I don't know if this still happens but it was widespread a few years ago.  Basically if the User-Agent doesn't say "I'm a phone" the request is blocked.  There are ways to change the User-Agent on some PC browsers so it might be worth giving that a try.

How can I get the Car Home app to work?
I'm running KitKat and can't locate the Car Home app on it. It's listed in the Play Store as "Installed" and also "incompatible with all your devices", also "not eligible".
There's a seeming incongruency in the app install versus availability, and an inability to access the the app on my devices: no icon, no ability to add a shortcut to the launcher?
I've not seen another app in the Play store reporting itself in this odd manner.  My immediate assumption is it has been discontinued and/or is installed in the Android OS but only makes itself available under certain conditions (e.g. a docking station is present).
There does seem to be discussion around the Internet about the Car Home app and docking station integration.
Back in Gingerbread days I used to open the Car Home app manually to use it.  I haven't checked for it in a while.
Currently I'm running a Nexus4 with KitKat but I think this doesn't seem to matter. The app also won't work with my Note 10.1 and is not available for the old Nexus S either (lost that phone though so I'm only going by what the Play store is reporting for it).
I've settled for using a third-party app for now, however if Car Home is part of Android and the Play store I would prefer to use it.

I use Car Mode Ultra. It's highly customizable and more useful than the old car mode from Google

There are 2 ways I have seen things that existed on the phone that did not have a application button, or shortcut.
AnyCut (or better cut) Anycut can make shortcut widget things for almost anything , all the normal things are already in it (the apps you know). There is also this huge list of junk that is not easy to navigate , and sometines is very poorly marked Like every settings item in existance.
Better cut attempts to assemble the data better in catagories, but not all items will exist in better cut.
With Anycut I have made direct buttons for deep settings items, and stuff I never even heard of.  Any Cut might be useful for finding stuff, and setting it up with an icon to run.
Any good explorer, with the option to see hidden, even though without root you wont be doing much with it.  Duel file manager, astro, ghost commander, just about any of them except the built in file managers which are often more simple.
With the explorers viewing and even searching for all items on the device, I found the jelly bean easter egg executable, and ran it, before ever knowing it was an easter egg.  Searching with a wildcard etc.  Most of these explorers have some way to run things that will run, or view.
Never know what you can find :-)  That is a few ways to look. I am runing testing now on the app called Ultimate Car Dock , it is large button interface voice interaction, shorts contactcs and apps. read and replay to messages with voice It is "ok" so many others did not even get this far. 7day trial pay app.
Analisis of UCD , it works , it has to be task ended with its services set to task end to stop working , or be reset in settings. It was not so easy to get it to stop, which is both good and bad, good that a lot of programs fail over time, so this did not.
Needs more settings to reduce the interaction as the method is learned, eventually a person wants to tell it to shut-up and visually present less info.
Has the same fatal flaw with voice recognition that most everything else has, a "translate to text first" approach, then "programatically compare the STT text" that was poorly recognised. (this method would work if there was a large "sounds like" compare for the limited choise triggers).
Other than that it was fully operational, very usable by clear speakers and TTS knowlegable, very frustrating for mumbling non-tech people.

What is this "com.android.backupconfirm"?
What is the package on my phone that is called com.android.backupconfirm? I tried Googling and found an answer on a random forum that said that is the UI for the backup confirmation dialog. While this sounds correct, could you explain why this isn't a part of the core but instead a separate package?

To what app should it rather belong? My guess is it's belonging to the dialog popping up when initiating adb backup, and which does nothing but asking you to confirm whether the remotely triggered backup should be executed (and if you want to protect it with a password). There is no related backup app in the core system, which you could start directly on the device, and which this could be part of.

After googling around a little, I found the source code of BackupRestoreConfirmation.java, which is used to build the package com.android.backupconfirm. Quoting from its comments:

Confirm with the user that a requested full backup/restore operation is legitimate.
  Any attempt to perform a full backup/restore will launch this UI and wait for a designated timeout interval (nominally 30 seconds) for the user to confirm.  If the user fails to respond within the timeout period, or explicitly refuses the operation within the UI presented here, no data will be transferred off the device.

So this confirms what I already guessed in my comment on the question itself: it's belonging to the dialog popping up when initiating adb backup, and which does nothing but asking you to confirm whether the remotely triggered backup should be executed (and if you want to protect it with a password).
As the comment is further speaking of a backup manager service, one could also think of the Google Cloud Backup (see: google-backup). So let me again stress some important keywords from the comment's start:

a requested full backup/restore operation

Google Cloud backup neither is a "full backup/restore operation", nor can it be "requested" by the user. The only backup service this applies to is adb backup.

FYI, not only backups/restores require this prompt, but also Restore Default Settings and Factory Data Resets need it.

Android 4.3 autoscreen turn on
This issue I noticed,once i updated my android to 4.3.
The issue is after every 1 min the lock screen automatically turns on.
There was no problem before.
Please help,i dont want to degrade to 4.1 again.
Device-Samsung Galaxy Note 2.

I don't think there's enough information here for us to help you. From what I've seen of similar issues in the past, there's probably some app that needs to have the screen on in order to function. What do you have that updates every minute? You might need to start taking apps off and using a process of elimination to find the culprit.

Full ack to Al's comment, and let me add something: A "full wakelock" does such things (turning the screen on to make sure the device is fully awake). To find the app requesting this, a useful resource thus might be How to deal with (orphaned) WakeLocks?

I'm having this problem as well, on the exact same device.

I don't have a Galaxy Note 2, but I would recommend just turning on Debug mode and running adb logcat and hoping that you can see the culprit make an announcement when it happens.

Using WakeLock detector from the wakelock thread, the only apps that seem to trigger a screen wakelock are the default messaging app and the package installer. I've turned both of these off, and the screen still keeps turning on.

Using Tasker?  (or Locale, Llama, etc)  Tasker has a compatibility setting that turns the screen on when checking certain conditions.

@smhmic, nope, I am not using Tasker or those other apps :(

@stringo0 Have you tried turning Sync off? Maybe there is a sync adapter that is misbehaving.

@Andris, yes I have. I'm starting to think it could be a hardware issue with mine.

I also recently upgraded my Note2 from 4.1 to 4.3 and was having the same problem. I installed the Wakelock Detector by UzumApps and found that the Noom Walk pedometer app was waking the screen. I uninstalled the Noom Walk app and the screen no longer wakes. The Noom developers have posted a test APK which can be found here: http://noom.uservoice.com/forums/207934-feature-requests-noom-walk-/suggestions/4147991-fix-noom-walk-on-the-samsung-galaxy-note-ii
I have not tried it yet. I may post more later if I try installing it.

That seemed to be it for me! The Wakelock detector didn't show the Walk app waking the screen, but uninstalling it has fixed it! No wake ups any more! Yay! Thanks for your help!

Glad I could be of assistance!

Android has different lock options - PIN, pattern, or facial recognition,.. .
Change current lock option to other and see if issue still exists.

Thanks for the suggestion @MAkS! It didn't seem to work. I changed it and it still turns on every minute.

Check if you have 'Daydream' turned on. Settings->Display->Daydream on Android 4.4. I was playing with my Nexus 7 and noticed that it would bring up the clock when I left it alone so it could be that. I must have turned it on when I was playing around with new features as it was introduced in Android 4.2.

Non GPS Positioning
I get map positioning in iPad without GPS.
Any clues on how to get the same thing in an Android phone?
I tried it on google maps, maps with me, always with wifi on and no result unless I'm connected to the wifi network.

Your device needs some source to extract the location info from. That's either GPS, or the network (in combination with cell and WiFi IDs). The IDs themselves give no position information, it's the databases on the network where those IDs are looked up in. Which means, you either need GPS, or a data connection (WiFi or mobile). Simply having WiFi on, but no data connection available, cannot do the trick.

Additionally, in order to get an approximate location from wifi alone, the AP you're connected to needs to actually be in the wifi location database - in addition to actually providing a data connection - which it often isn't.

I understand what you say. But in the case of my iPad, it does not have 3G, only wifi, and it positions itself on either purchased or cached (i.e.google maps)maps...

Go into the main Settings app. Find Location access (Location services on some phones) in the list of settings pages, and make sure all the settings in that page are on, in particular Wi-Fi & mobile network location (which might have a slightly different name, such as Use wireless networks).
When you turn this option on, there's a dialog warning you that this periodically sends the visible Wi-Fi networks to Google. This is how the location mechanism works, so you have to agree to it if you want this feature.
Even when it's on, it only works when you're connected to the internet (either through 3G or Wi-Fi). It works by sending Google the list of Wi-Fi networks you can see. Google has collected a database of Wi-Fi network names and real-world locations, so with this information, they can reply to your phone with its approximate position. Obviously this can only work with internet access.
The similar feature in the iPad works exactly the same way, only with a different database maintained by Apple instead of Google.

I am sorry. But I use my iPad which is wifi only all the time in different cities around the globe in this way: I get connected to the internet, cache a portion of a map, and then when I walk a city I get position display...

You can do this in iPad or iPhone anywhere.

Without actually being connected to the net. Apple uses crowdsourcing. They continuously assign positions to ip's by extracting that info from wifi / gps enabled devices, integrate this into a data base. And then when you load a map, it has that info embedded. So you walk the city, no internet, no gps and get perfect position display.

I am crazy with this cause I just got my first android phone and realized I m not able to do the same thing...

How can I update the radio-firmware for my Galaxy Note 2?
The radio on my Galaxy Note 2 has been acting up and I've read that this can be fixed by updating the baseband/radio-firmware.
Where can I find the firmware for my device? My device's baseband is currently shown as XXALIE. Is that the only firmware I can install or can I choose any of the XX ones.

Radio firmware is usually provided by the manufacturer directly. But you might want to check Where can I find stock or custom ROMs for my Android device? for additional sources; it's not a rare case that a source for custom ROMs points to recommended radio-firmware to be used along.

Try searching in the XDA forums. You would have better chances there.

XDA is the place to try. You'll need the USB drivers and ODIN to flash it, and to ensure NO Kies services are running. Ensure the modem is for the EXACT model of Note 2 you are using. Also Modems are region specific so the 'latest' one may not work on your network. Make sure you have a few downloaded, including your current one as backup before flashing a new one. (I recently made a complete mess of it myself so just a friendly warning!)

What size of SIM card Nexus 7 2013 LTE TMo comes with?
I cannot find any mention of which SIM the newest Nexus 7 32GB 2013 LTE TMo comes with.
Is it Mini-SIM?  Micro-SIM?  Nano-SIM?
The page only mentions that it comes with a SIM ejection tool and has Micro USB.

https://support.google.com/nexus/answer/3256561

Why is the question downvoted?  Is this information on the SIM card size of the device somehow available on the official page I've referenced that I've missed?

@cnst - I suspect people are downvoting because the answer is pretty easily obtainable via a google search for nexus 7 sim card size, the first result for which is the link  eldarerathis gave in their comment.

According to GSMArena, the Nexus 7 2013 uses a microSIM.
Google's help page on inserting the SIM further confirms this.
I would fully expect that Google would include a SIM of the appropriate size, unless they've completely reneged on their "Don't be evil" bit.
If not, just break out your scissors to cut it down to the appropriate size and shape.  The extra size is just empty plastic to make handling easier.  The only important bits are directly under the connector.

Well, my question was of what the appropriate size is.  It's not mentioned on the page.

The appropriate size is microSIM.  And unless Google is being mean, a microSIM is what they'd include with the tablet.

You're unfairly making fun of my question.  I'm not asking if they include a SIM card that's compatible with the tablet, that'd be a dumb question indeed.

@cnst - I'm not intentionally trying to make fun of it.  I'm just apparently misunderstanding what exact information you're asking for.

I'm just asking for the information that any decent manufacturer includes right on the specs page of their product, that's it.  E.g. http://www.apple.com/ipad-2/specs/ is pretty clear about saying Micro-SIM card tray (Wi‑Fi + 3G model), whereas there is no such mention on the Google spec pages for Nexus 7.

@Compro01 Even less than that! :> Take a look at new iPad Mini / iPad Air / iPhone 5 and their nanoSIM cards. If you use proper card cutter to cut SIM/microSIM cards to nanoSIM size, you'll clearly see, that outer parts of connector itself are also cut-off. I was shocked at first to find this out! :>

How to dismiss an individual entry from the Calendar Notifications list?
On my Nexus 5 phone running Android 4.4, if I have several calendar notifications come at the same time, I can easily dismiss them all at once by either:
1) pulling down the notification menu (screenshot below) and then swiping to the right over the entry labeled, say, "3 events" as seen here:

2) tapping on "3 events" from the notification menu to display the Calendar notifications list and then tapping the "Dismiss all" text at the bottom, like in this screenshot:

I'd like to dismiss individual event notifications from the calendar notification list seen in option #2 above, for those times when I get a couple activities done but not all at once.  I see no way to do that, though, other than to tap on each entry, which then pulls up its full calendar entry, and then tapping the back button, which brings me to my full calendar view, and then going back into the notification menu, selecting the events entry, and repeating.  Swiping to the right over an individual entry on the calendar notifications list does nothing.
Is there a quicker way to remove select entries directly from the calendar notification list that I'm missing?  On my old Android 2.3 phone, I could mark a little checkbox next to each entry on the calendar notification list and dismiss only selected reminders, but I see no way to do that in Android 4.4.

I have the same issue on Android 4.1 Jelly Bean.  And like you I used to be able to do it on my old gingerbread phone.  Annoying that is seems they actually took functionality away in later versions.

Keyboard punctuation
I just updated my phone (Galaxy S3) and I don't like the new way auto prediction works, it keeps trying to predict the next word instead of giving me quick access to the punctuation. Does any one know if there is a way to have the auto prediction just give you a list of punctuation once you hit the space bar instead of trying to guess the next word?
When I originally got my phone last year when ever I finished texting a word and hit the space bar, the auto prediction bar would show all my punctuation and that was great. Than I did an update a several months ago, and the auto prediction started giving me next word predictions instead, the only way I could find around that was to double tab the space bar, than hit backspace/delete, and that would allow my auto prediction to once again show the punctuation available. It was a few extra clicks but at least it was still quick access to punctuation and didn't slow down the flow to much. But with this latest update auto prediction only seems to give word suggestions, I can't find anyway to make it show me punctuation. Any help would be appreciated. Thanks all.

You might try a different keyboard.  Hacker's keyboard's (my preferred keyboard) autocomplete seems to do what you want.

I have a galaxy Note 2. I opened a new message and at the top of the screen is a keyboard symbol. I pulled down the screen to then be able to "choose input method" which I tapped on. I then tapped "set up input methods" and tapped the settings icon next to "Samsung keyboard" which then allowed me to de-select predictive text. I've now been able to customise my settings a little.

If you're using Google keyboard turn off Next-word suggestion option in settings. This way you will get the bar back after finishing each word.
