How to access the phone via adb; broken screen
My karbonn s2 screen got cracked ,i need to transfer my contacts on pc.i tried using droid at screen (adb).since i can't go to usb debugging option because of damaged screen.While using droid@screen it doesn't read the device.How to solve it ? any help would be appreciated!!

Yupp. And all the other "duplicates" of this frequent question (← Welcome to Android Enthusiasts! We have a nice search feature ☺)

If the Karbonn S2 has an HDMI output you can painlessly attach an external monitor.

By default your contacts are sync'd to Google.  You should be able to find your contacts by logging into Google and looking at contacts under gmail.
Also when you get your replacement Android, just setting up the same account that you did for your broken android will bring all your contact to the new android.
Of course if you, for some reason, disabled the automatic sync, this method wouldn't work.
But again, without any changes or having performed special configurations on your part.  This will work.

Update information for consideration:
For some (particularly me) my data is substantially more important than the hardware.  A resource to consider in gaining access to your android is to actually repair it.  It's more expensive than some of the suggestions and links provided by Dan Hulme, Izzy, AI E, Chahk, and andeldererathis.  But it's very likely to get you your important data.
First, the cracked screen won't stop your access to your device.  However, a damaged touch screen will prevent you from being able to access it.  To the surest way to resolve the issue is to invest in repairing the touch screen.
You may find the replacement part on Ebay or Amazon.  This is an idea of what would be involved:
Youtube: How to disassemble karbonn a15 completely:
Again, this is a hardware resolution to recovering your data.  Working with the tiny parts isn't something that most of us can handle.  So you'll have to search for a service center to do it for you.
While rather timely and expensive, it's not as costly as trying to hire clean room services to recover data from a hard drive.

Thanks, i checked that already but all in vain.I think i have disabled the automatic sync as you said.But how to get access the phone ,i need to recover all my msg and contact.does there  any other option  to solve it?

@ashish I updated my answer with a detailed "other option".

How to flash Android onto an empty Samsung GT-P3100 (OMAP4430)
I'm about to purchase a replacement motherboard for a Samsung Galaxy Tab 2 7.0 (GT-P3100) as the original one has developed a hardware fault.
Unfortunately the sellers (eBay) won't say if Android (or anything else) is preloaded on the boards.
So assuming that the boards come completely empty, how can I flash this board?  Would the OMAP4430 be configured so that it follows a boot sequence similar to the one described on OMAPPEDIA.  For example, could I load ClockWorkMod via a SD card or USB?
If USB is included in the boot sequence, what tools would I need to flash the system?

"Internet not available" error while trying to connect to wifi
I have a samsung galaxy chat B5330 device.
Whenever I try to connect it to wifi, I get various errors as follows,

Using DHCP :- Here it shows a "obtaining IP address" message but never connects.
Using Static IP :- It connects to wifi but then shows a "internet not available" error. I'm sure that internet is available as many others use it successfully using other android devices/laptops etc.

EDIT:
I found out that not all are able to use the wifi. Some do not get connected(stuck in "obtaining ip address"), some get the "internet not available" error, some connect and get internet but at very slow speeds(10 KBps download speed) while some lucky dudes get blazing speed(10MBps download speed)
Could this occur due to to many signals at same place? At any given place in campus, we get at least 2 strong and 1/2 weak wifi signals, not to mention some secured portable wifi hotspots from androids.
How do I solve this error.
Note that I don't own the router/wifi, it's open(No security, accessible by any student.)

Could that be a MAC filter on the routers end? Doubtful (if anybody else can connect fine with any device, even new ones which never had connected to it), but the first thing coming to mind.

@Izzy Could this be due to too many routers? There are 1 to 3 routers at every floor, so we always get at least 4 signals at any time(few from same floor and few from above and/or below).

I don't think so (or I would have the same trouble here, with always ~10 APs in reach). I'd rather say it depends on which AP the device tries to connect to, one of them might be the culprit. But that's rather not an Android specific question I bet. It better fits the "personal and home computer networking" topic covered by [SU] – as long as it's not "specific to corporate IT support and networks" (off-topic there).

Seems DHCP is not enabled on WIFI router, you may need to ask others to obtain DNS
address, to connect to internet, DNS info is required as well

How can I factory reset my Android Mini 7100 Phone?
I'm unable to go to recovery mode to factory reset (wipe my cache/data) my Android Mini 7100 Phone (Android GingerBread 2.3.x) because I forgot my phone lock combination.
I tried resetting it using:

Vol Down + Power,
Vol Up + Power,
Vol Up + Vol Down + Power,
Vol Up + Vol Down + Home + Power,

and the phone starts normally

When I press Home + Power, it goes to 'Test' mode.

I checked out this YouTube video but it did not work for me.
How do I go to recovery mode?

Normally, if you enter your password wrong a few times, and you've tried or can't unlock it with your Google account, it just offers to factory reset from the lock screen. Might this be an easier solution for you?

@DanHulme Thanks for the comment but the only options are Sign in and Emergency call. I don't know the gmail account used too.

How many Gmail accounts do you have? ("my Android Mini 7100 Phone" vs. "I don't know the gmail account used" seems a little contradicting)

@Izzy Sorry for the confusion. The phone was my sisters and she forgot password of the gmail account she used. That's why. Any solutions to get into recovery mode?

Personally not. But you might look here and watch a bunch of youtube tutorials on this (people often confuse the factory-reset with the hard-reset, though the latter is rather corresponding to "power unplug").

I think the easiest (and non-sketchiest) solution for this will be to help your sister recover her Gmail password. Once you have that, you can use the Android Device Manager to reset the phone password, or erase the phone memory from the computer.

This is the only solution I will post here because resetting an android without access to a gmail account is often done with less-than-ideal intentions.

Maybe you are missing or failing to do something very important:

Switch off your Phone
Press and hold the Vol Up + Vol Down + Home + Power buttons together until a dead Android image no command shows up
Press the power button to show recovery options
Navigate with the volume up button
Select and choose "Wipe data and factory reset"
Scroll to "YES" Use volume down button to choose. Wait till data
wipe is complete.
Now, select "Reboot system now"

Did you try ADB?, there may be a chance your device can be recognized by adb although its locked.
If adb can see your device than run the below command and wipe data and factory reset

adb reboot recovery

this only works if the user has enabled usb debuggin

Is Android connected with Ubuntu by the expected style?
I need a bluetooth connection between Android Ice Cream device and Ubuntu 14.04 laptop.
I am able to transfer ordinary files through a bluetooth connection which is attached as a picture below.
But when i
adb connect xxx.xxx.xxx.xxx
within SDK directory,
i hope some connection appear, but could not.
Also as you can see below there is an "OFF" in the picture.
I wonder if this is the key problem about my bluetooth connection.
I think my server is up, because application can run on emulator.

This site works best when your question is a single question with a correct answer. You seem to be prodding around different things, suggesting there's really one problem to solve behind all your questions. It might be easier if you [edit] your post to be a single question, about what you're really trying to achieve.

Don't know – depends on – yes – no idea. +1 to Dan's comment. Plus, most of the topics have already be dealt with here multiple times, so while "cleaning up" your question you could remove them – after finding a fitting solution via our [search] and our adb tag-wiki, for example ;)

I find bluetooth connections with Ubuntu to be a bit unreliable.  I have tried it on a number of machines.  I have also tried a variety of bluetooth adapters.  I'm not sure if it's the various adapters that I've been using.  I tried to find a recommended bluetooth manufactor specification, but didn't have luck.
It's not clear what you mean by

adb connect xxx.xxx.xxx.xxx

It's my understanding that you have to specify a port when you use the adb to connect (outside of using a direct connection from the USB).
You can have very reliable transfers and connection using your USB or your wireless.  Since you make a reference to adb, I'm sure you already have the Android SDK package installed.  So you have access to the adb transfer features (push/pull), using the USB connection.
To use the wireless connection for adb you have to first connect USB then activate the adb tcpip connection to your android.  This is done by issuing the following command and specifying the port you want to use.  After this activation you can unplug the usb cable and have adb wireless connection that will last until your android is rebooted.
$ adb tcpip 5123

In this example I specified a port that would be unlikely to be a default port for an automatic connection such as an avd.
After you have activated the wireless adb connection for the android you can connect to it by specifying it's IP address and port when issuing your connect command:
$ adb connect 192.168.1.102:5123

I believe your problems connecting adb has to do with your connection setup and parameters.

Tasker - Count The Amount Of Days Since A Certain Day
the title says is all
I want to create a task that holds a count from a certain date
My goal is then to use minimal text to display the amount of days, that part I know how to do it's just getting Tasker to do the sums
Any ideas?

You first have to convert both dates to seconds using Variable Convert.  Then subtract those two values to get the number of seconds between the two dates and convert that value to the number of days by /24/60/60 (hours/minutes/seconds).
Here is a sample task that illustrates using 08-01-2014 as %startdate and today (%DATE) which is 08-23-2014 as %today.  The result is 22 days.
A1: Variable Set [ Name:%startdate To:08-01-2014 Do Maths:Off Append:Off ]
A2: Variable Convert [ Name:%startdate Function:Date Time to Seconds Store Result In:%startdateinseconds ]
A3: Variable Set [ Name:%today To:%DATE Do Maths:Off Append:Off ]
A4: Variable Convert [ Name:%today Function:Date Time to Seconds Store Result In:%todayinseconds ]
A5: Variable Set [ Name:%secondssince To:%todayinseconds - %startdateinseconds Do Maths:On Append:Off ]
A6: Variable Set [ Name:%dayssince To:%secondssince / 24 / 60 / 60  Do Maths:On Append:Off ]
You could shorten this a bit by eliminating A3 and replacing %today with %DATE in A4.  Also, you could combine A5 and A6 by using (%todayinseconds - %startdateinseconds) / 24 / 60 / 60.  I split it up only to show the individual steps better.

Thanks for the reply! I ended up just figuring out the days and then adding 1 to it each day, but I will try this out for future reference!

No problem. I hope it helps you.

Samsung Galaxy S5 Mail download size problem
I think I've came across to some sort of bug in Samsung Galaxy S5, (SW-G900W8), Android 4.4.2, (Kernel 3.4.0-1947824).
The problem is, after the mail account being setup correctly, the default mail client on the phone will not download all the mail but only the headers.
The "MAxEmailBodyTruncationSize" setting on the exchange server was set to 50KB , 100KB and unlimited but it has not solved the problem.
Another samsung phone (not the same model) gets the settings correctly (50KB, 100KB, unlimited respectively).
SO I'm pretty sure this has nothing to do with the server. Do you have any suggestions? Other than maybe using another mail client on the phone?
Thanks,

We had the same issue, and also tried setting it to "unlimited" without that solving the issue. We think the S5 is reading in bytes and S4 in KB. Finally, entering the limit in bytes solved it for us.
Can you try to put 1000000 in the limits and re-create your account on the S5, what choices of limits to you have while setting up your device at that moment?

This is how I would fix the problem on a Galaxy S4.
Open up the following menus in your phone (with the S5, they may be slightly different):
Settings
Accounts
Email
Settings
Primary Account
Sync Settings
Size to retrieve emails
Within this menu, you should be able to adjust the settings (on your phone) for "Size to retrieve emails" and "While Roaming". Make sure both of these settings are set to download more than "Just Headers".

No, the settings can not be changed (I know how to change them), the only option is "Headers Only" whereas on most other phones it lists all the options. 5K, 10K etc etc

Well good luck with the S5. I'm sorry I couldn't help ya.

This is likely a bug introduced in one of the latest updates to Galaxy S5.
The functionality was working before for my phone: emails downloaded and you could set the size, but it stopped working during the summer (and I remember there was a system update downloaded).
I'm also using Exchange email on my Galaxy S5 and see the same symptoms (headers only downloaded, cannot change setting from Headers only). I have a second IMAP account configured, and that works normally (you can change the settings and message body is downloaded).
Unfortunately I haven't found a fix to this bug.

In case anyone is still looking for an answer, hopefully this will help out. All our S4,s, S5's and S6's had the same issue but only for the built-in AS client and only for those running Lollipop. So I did some testing and found something interesting:
The old set-activesyncmailboxpolicy is deprecated in our up-to-date E2013 servers. That command set the size as a straightforward number of KB i.e. a plain number with no qualifier. However, it appears the policy format has changed along with the editing command and it now takes a size qualifier of GB, MB or KB, with unqualified numbers now meaning plain Bytes. That suggests that the AS client in Lollipop is actually being quite strict as to how to read the new style, whereas Touchdown and Outlook clients seem to assume that unqualified numbers = KB as before.
So it's not really a bug, rather MS not thinking about backward compatibility as hard as they should have (how tough would it be to allow a B qualifier and assume unqualified was KB on all AS policies?). So all you need to do to 'fix' the issue you need to edit all your activesync policies with the new command and make sure to use an appropriate size qualifier. Btw - I've no idea if this applies to older versions of Exchange.
Example (for the Default policy - rinse & repeat for any additional ones):
set-mobiledevicemailboxpolicy -Identity Default -MaxEmailBodyTruncationSize 200KB -MaxEmailHTMLBodyTruncationSize 200KB

Phone Storage Problems
I am having an issue where I have no free space. I have deleted a few apps and removed cache from all and it gives me some free space. I then go to delete to a text message from microsoft and I cannot get to the menu to delete it and messages crash and I then have no free space again.
Anyone know how to fix this issue? Is the message causing the lack of space problem or is the lack of space causing the message app to crash?
Thanks
HenGreer

You're probably having a problem using your device because of lack of internal space for running programs.  You can use a very low level, low resource on the Android to remove programs.  Install the Android SDK package and use it to uninstall some of your apps to regain internal memory.  You can even use it to back up the apps on your computer so that after you have your android working again you can choose which ones to put back.
A good GUI program for managing your apps and deleting files from your android is Airdroid.  However, you might not be able to install Airdrod until you've made space using the Android SDK package.
You can start out with these commands:
(You'll have to activate Debugging from the settings menu in the android to use this option)
This give a list of all the packages:
$ adb shell pm list packages

You can remove an app by running:
$ adb uninstall [apt-name]

You can use the "-k" option to retain your data/cache in case you will be reinstalling the app after you have gotten your android functioning.
You can us this command to see how much memory you have.  This will allow you to know when you have retrieve sufficient memory to operate normally.  It'll also allow you to identify better, if the memory is really your issue.
$ adb shell cat /proc/meminfo

You can look at Is it possible to backup apk from an installed application? for more tips on using the adb command.

Dual SIM: Disable telephony features on second SIM
I have a Samsung Galaxy S Duos 2 (GT-S7582) with two SIMs. I'd like to use one of those SIMs for everything telephony related, the other SIM for everything data related. I managed to set the first card to be the default SIM for outgoing calls, and I deleted the APN for the first card so that only the second SIM is used for data.
However, I still receive calls for the number of the second SIM. I also get the choice to call using the second SIM, which I do not want.
How can I disable receiving calls from the second SIM? How can I fix telephony/data even harder to the individual SIMs?
Android version: 4.2.2
EDIT: As a first workaround, I disabled the default ringtone for the second SIM. This way only the display lights up, which is easy to ignore.

You may be able to semi-disable incoming calls on one sim. A lot of cell companies allow you to set up call forwarding and other options using special codes. Look up the shorts codes available for the carrier of the SIM for which you wish to block calls.

I have two SIMs sharing a number, and only one of those is in the dual SIM phone. Sadly, if I change the settings you mentioned, this affects both of these sims - meaning that I also cannot receive calls on my other (non-dual SIM) phone. In other words, I need a solution that is configured for the phone only.

Really? I didn't know you could ever have two SIMs sharing a number. So if you call the number, both phones ring?

Correct. It's called Vodafone UltraCard.

You can achieve this by applying call barring on the SIM.
Although I know this is a different Andriod version, I am sure you will find something similar to this on my OnePlus 2.

Phone app > Settings > Call settings > SIM 2 > Call barring > Incoming call barring

Can you please improve your answer by making a sentence or adding details.

@Maxime done as requested

Any idea how to do this on Android 11 (e.g. Pixel 4?)

Programmatically, how does "rooting" a device enable access?
From a layman point of view, one would say, "Oh, I'm unrooted so I am blocked and access is not allowed." I want the programmatic point of view; telling me how an unrooted device doesn't have access to the whole filesystem, etc., and how a rooted device has that access.
Examples:
1.Is the filesystem set by default to disallow reads/writes to /system, /sys, /data, etc.?
2.Is there something stored in /system or /data (such as a program, block device/file, etc.) that the unrooted OS runs that limits system-wide access on several tasks that rooted users have?
3.Does the default "unrooted" OS actually have system-wide prevention of unrooted access?
Because look at it this way: to "root" your device something must be changed, right? So the "rooting program" or process must entail how this restriction is circumvented. Does anyone here/can anyone link to anything (or explain it) that explains this process of how the rooting progress allows users access they weren't normally given by default (programmatically; not details on steps to follow in a rooting process and not info on how to root on your phone from a user's point of view; from a developer's point of view).
Best example: Say I'm an Android developer and I wish to learn how to create a rooting program. What would I, for example, need to know to do this?

The vendors want to make as much money off you as possible; and they don't want to have to provide tech-support if you shoot yourself in the foot. So the normal "user" of a phone does not have full rwx permissions everywhere. To root a phone, you need to "exploit" a mistake (a hole) left by the vendor in your version of hardware/software (they tend to fix them all the time) to run a program of your creation with full root (user id 0) permissions. That program can then leverage everything else.

Your question is less about rooting, as much more about how permission management works, and how partitions are mounted. You might wish to see our file-permissions tag-wiki for a start. These are rather generic Linux topics than an Android issue ;)

Root is a Linux term for the highest level administrator. To root your phone means giving yourself root level privileges. These privileges include being  able to manipulate the file systems protected partitions. To root is an exploit in Android to give yourself this ability.

Why does Yahoo Weather limit my wife to 2 locations but not me
Yahoo Weather allows me to add any number of locations.
When my wife, on the very same Nexus 5 phone, tries to add a third location, it asks her to delete one of her existing locations.
What's going on?

Have you checked if you and your wife are using the same version of Yahoo Weather?

I have checked.

This question appears to be off-topic because it is about a transient bug in an app.

And how would I, or anyone else, know that in advance? I mean, go ahead and close, but it seems a strange criterion.

When you say "on the very same Nexus 5 phone", do you mean that your wife also has a Nexus 5 phone, or did you create a second user profile on the same Nexus 5?

A second identical phone.

Could you post screenshots?

No, this was fixed on Aug 6.

Removing and reinstalling Yahoo! Weather on my wife's phone cured this. I guess Cousin Yahoo! has a bug.

Automatically runs Dolphin Browser on boot up
I am new here.
I have some android sticks. I use them to run a kiosk. That is some kind of newspaper on a big screen.
I runs in the dolphin browser.
I want that my clients just have to power on the screen and stick without having to click once.
Is this possible in adroid.
I use 4.2 and 4.3.

You might wish to check other questions tagged kiosk-mode – a tag I've just added to your question. Good luck!

you cant make dolphin run on startup, but you can use an app called Kiosk Browser Lockdown
https://play.google.com/store/apps/details?id=com.procoit.kioskbrowser&hl=en

There are a variety of apps specifically dedicated to autorunning apps on startup, as well as apps such as Tasker that could accomplish similar. Your kiosk suggestion is a good alternative, but your assertion that you can't run Dolphin on startup isn't supported by the facts.

How to Set the default storage of apps in my samsung galaxy young?
I have a samsung galaxy young. How can I Set The Default Storage of my apps from Internal memory to SD card. I can't Download Anything right now. Can you tell me how?

I'm pretty sure the same advices valid for other devices will apply to the GY as well. Specifically check: How to Install Android Apps to the SD Card by Default

You first priority is probably to clean-up downloaded files, cached files, old APF (installation) files to give yourself more room and operate more efficiently.   You can clear cache individual applications through settings > applications > clear cache.
Use any File Explorer to remove files no longer needed or no longer wanted from your
downloads.  Each browser normally has its own downloads folder.  "SD Maid" includes a File Explorer if you don't already have a separate application.
You can clear cache files much quicker by installing
"Clean Master"

get rid of "Junk Files" such as cached files

"SD Maid".  Some items within  are

"Overview"  help to see what you are working with.
"CorpsleFinder"  find and delete files SD Maid believes belong to your old/deleted applications
"AppCleaner"  is a premium feature so you can use "Clean Master" to get rid of cached files, would need to mount your removable SD card, and once mounted, you would have to unmount the card before you physically  remove your card.
Settings > Storage > External SD Card > Mount/Unmount SD card.

You have to set default storage individually per application.  Some applications would slow down everything if they used your removable SD Card storage, such as "play store", and applications that start at startup.
To move an application to your SD card:
Settings > Applications > choose application > "Move to SD card"
To choose applications:

A question about bricked phone (moto g xt1032)
I hav moto xt1032. In short I can only access recovery and cmw. However it seems that either my usb debugging was turned off or there is somehow some sort of malfunction and in cmw adb does not detect my device (I have seen posts claiming that cmw does not required usb debugging off to use adb but still it does not work while it used to work previously). Mount as usb does not produce any effect neither
I need to somehow push a stock rom into my phone so I can use cmw to install it. Adb not working, sideload does not work as well. So is there any way out of this? Thanks
update:
0- my fastboot recovery command is working so I tried flashing recovery from twrp which works.But it can not for instance mount as usb neither.
1- I have tried using fastboot update rom.zip it says android-info.txt missing (and some more txts)
2- I can use fastbppt to flash files into to a flash partition but I guess they are not reachable by twrp or other recovery apps

How do I get 2 way photo syncing with dropbox?
I have Dropbox auto uploading photos that I take.
What I'd like is to have deletions or reorganizations of my photos on the phone to be reflected in Dropbox and also the other way around?
How do I set this up?

This is not possible. Dropbox says:

Dropbox will not delete files from your mobile device after they are uploaded. The files on your camera, phone, tablet, or SD Card will remain on your device until you remove them manually.

To do this, you will need a third-party app, like Dropsync.

Samsung Galaxy GT s7562 WiFi stuck at "Turning On"
The WiFi on my Samsung Galaxy S Duos GT s7562 froze. It shows "TURNING ON" and stays forever like that.

I tried a hard reset. Still not working.
I tried some dialer codes (like *#*#526#*#*) to restart the WiFi drivers, etc. and the codes are not working. It's just dialing.

Are there any other solutions?

It stays same even after 2 or 3 hard resets.

I tried the previos mentioned steps from this page ->   http://techblogpremium.com/samsung-galaxy-s-duos-s7562-wifi-fix-method/

http://android.stackexchange.com/questions/78599/samsung-galaxy-gt-s7562-wifi-freeze-showing-turining-on

WiFi hardware was faulty. (This is a common issue)
The WiFi chip set no more working. So the whole motherboard should be changed.
Costs nearly 5000INR (80$).

guys if your problem is wifi on your phone and if you do hard reset and still not working, the problem is hardware, the wifi driver. hard reset is the solution for software only not hardware.

That was already pointed out in this answer: "WiFi hardware was faulty". Apart from that, don't confuse hard-reset with factory-reset. Hard-Reset is only a solution to "switch your device off" if that can't be accomplished by other means ;)

conversion printing app from landscape to portrait mode
I often work just with the smartphone (Galaxy Note 3, Android Kitkat 4.4, no root) without any computer.
After opening a landscape powerpoint-presentation with the smartphone, I want to print it in portrait mode (2 slides per page). Is there any solution?
If there is no direct printer app with Remote Print it would also be very nice if there would exist a conversion app to save a conversed ppp in portrait mode as a new pdf. I'm searching since several months and would be so thankful and happy if there would be a solution!

I don't think there's an "on-board solution". There are several printing apps available, maybe one of those offers what you're looking for.

One of the best apps for your (=my) aimis the app "Samsung Mobile Print".

Select 2 Up
Print it to your android device (use Google Cloud_Printer)
Wait a couple of minutes until your android device will download the new document (unfortunately this solutions converts colors to black/white, but for me it's okay)
Send the downloaded PDF to a normal Google-Cloud-Print or Remote-Print-App!

That's it!

Is displaying invalid content a violation on the play store
I have a suspicious app which requires all sorts of permissions Omega Status Bar.
I was facing an issue with the notifications,I reported this behavior to the developer and was surprised to know that the email-id given to contact them under the Email developer does not exist.(got a Delivery to the following recipient failed permanently error)

for which i have removed the app after that.Does google has any policy through which i  can report the app as an inappropriate app for having an invalid mail(invalid content displayed)
A link describing the related policy would be much helpfull instead of giving a simple yes or a no

You can report the app to Google. When visiting the app's page in the web version of the Play Store, there's a link for "Flag as inappropriate".
Under "Malicious or inappropriate Android apps" (and I'd say this probably qualifies) you are given two options for reporting the app. One through the Play Store app on your device, the other via a web site.

Application providers must adhere to the Google Play Business and Program Policies. If you see an application that doesn't follow these standards, you can report it by flagging it from the Google Play Store app on your Android device.

Open the  Google Play Store app.
Visit the application's page.
Scroll down and select Flag as inappropriate.

You can also report malicious or inappropriate apps to the Google Play team through the Android Developer Help Center.

While the app itself might not be "malicious" (though a comment reporting "push ads" might indicate that), the dev might simply have changed the email address and forgotten to update it on Play. Visiting the website looks like the domain has been abandoned (Godaddy placeholder) as well. So no matter what, there's no way to contact the dev but reporting the app to Google to figure out – and maybe leave a comment to warn others this might no longer be supported. +1 from me for the clear guidelines, Al!

@AI E. This is the Google Play site now which exact issue do I need to select for fake/in-valid mail id being associated with the application

What are these files in DCIM folder?
I was wondering if someone here knew what are these files:

I've put it in image format because their file names are weird? I just found out that these files are present in my sd card, inside the DCIM images folders and all images are gone except the thumbnails.
My images are gone and another problem is that I cannot delete them(maybe format but that's my last option i think). They stick in that folder and even moving isn't possible.
Any help or suggestions. Thanks!

Sorry I can't help but your SD card is defective. Try running a disk check on it on a PC, you may be able to recover some files. After that, reformat the card to use it again. However, in my experience, when a SD card has a defect you can't really fix it with format, it will break again. I recommend buying a new (and better) SD card

Thank you for your response.
Actually I can still use the SD card and access other files, but, yeah, those files are suspicious and probably harmful. And like what you've said buying one is the best and last option.

Back when computers still use floppy disks I saw these kind of files a lot. Floppies are not exactly known for their durability. These files are not really harmful, they are caused by mangled file information on the Allocation Table (which in turn is caused by a bad sector somewhere at the beginning of the disk)

@ThanhPhú You should write up your comments as an answer. After all, they do answer the question, "What are these files?"

Thank you @ThanhPhú, It seems that is the best answer for me. Thank you for information and advice!

These are not files but invalid file entries, caused by a corrupted allocation table on the SD card, which in turn is caused by a bad sector. A bad sector on the card is a good sign that card is defective and should be replaced.
You can try recovering some files by running a disk check program on PC.

How to trigger mouse-over in Android
I visit sites where some features like pop-up menus and tooltips are invoked by placing the mouse cursor over an item. I would like to use all the features while using my Android tablet. So, I'm looking for a way to simulate the mouse-over event in Android browser, especially in Android 4.1.2

I really wish there was an answer to this that worked with tool tips — otherwise some sites are really frustrating with Android.

The long-click is basically the same as a right-click which brings up context menus.
Things for mouse-over such as viewing titles, and link urls can be accomplished with bookmarklets.  I have examples bookmarklets to view all titles, and all href links, see "href:", "href-x:" and "parentips" on for instance  my dolphin gestures page.
You can invoke example by clicking on one of those boxed bookmarklets links.
To learn more about bookmarklets, if you are not familiar with them, I would suggest starting at http://www.squarefree.com/bookmarklets.

I see you assume I have installed Dolphin. Maybe I will if there is no other way. I wonder if Android addresses the problem somehow without installing third-party browsers

You can   implement boolmarklets  in any browser that has bookmarks and has Javascript withoutpt enabled.   I prefer Dolphin because gestures can be used to invoke a bookmark without using a keyboard.  I use boolmarklets in the default browser that comes with Android Gingerbread 2.3.4.     A big problem with Android is not havingreal scrollbars and why I am not using hundreds of bookmarkets on Android.    Click on the bookmarklets on the page I referenced and you will see they work in your browser.

This does not sound as though it works with tool tips (text displayed on mouseover) — or does it?

Long-press the item (to open its context-menu), then hit the "back" key (to leave the menu). Works on most devices. Explained e.g. here, scroll down to "Smartphones".

Long-press does not activate any menu. It starts text selection

Then you're not long-pressing on a link. I didn't check all combinations of mouseOver events, admitted. But when it starts text-selection, what happens then when you press "back"? Is the mouseOver executed or not?

Going necro on this since it was the most relevant thread I found when searching for a solution to this issue.
Based on the answer from @dmcritchie, I found the following works quite well to see tooltips when using Chrome on Android, which you'd normally only be able to see on mouse-over/hover when using Chrome on a laptop/desktop (Mac or PC).

When viewing this page on Chrome (Android app), open the menu, press ☆ to bookmark the page, then click "edit" on the notification that appears at the bottom of the screen to edit the bookmark.
Copy/paste the following to replace the name of the bookmark: πParenTips: Turns tooltips (title attributes) into parenthetical phrases. (https://www.squarefree.com/bookmarklets/sitespecific.html#paren_tips)
Copy/paste the following to replace the URL of the bookmark:

javascript:(function(){ var z=[],N,title,tc,j; function r(N) { if (N.title) z.push(N); var C=N.childNodes,i;for(i=0;i<C.length;++i)r(C[i]); } r(document.body); for (j in z) { N=z[j]; title=document.createTextNode("("+N.title+")"); tc=document.createElement("span"); tc.style.color="green"; tc.style.background="black"; tc.appendChild(title); N.parentNode.insertBefore(tc,N.nextSibling); N.parentNode.insertBefore(document.createTextNode(" "),tc); }})();

Hit the left arrow ← at the top to finish editing the bookmark.
The next time you're viewing a page in Chrome on your Android device and want to see all of the tooltips that you'd normally only be able to see on mouse-over when using a desktop browser, click in the address bar, type πParenTips (case insensitive), and click the bookmark you just saved/edited (it should show a ☆ before it). The javascript saved as the URL of the bookmark will reveal the tooltips in parentheses after every object on the page that has one.

If you want to take this a step further (which I did), you can and the javascript into a macro, and add it into the MacroDroid drawer. Then, rather than needing to remember the name of the bookmark, you can just slide open the drawer and click the macro to execute the functionality.
Here's the code for the macro. If you use MacroDroid and want to import it, just save this using a text editor as ParenTips(tooltips).macro.

If it doesn't seem to work on your device, you may just need to edit the coordinates for the UI Interaction(Click [x,y]) actions: (first one) to click the address bar in Chrome, and (second one) to click the enter/go key on your phone's keyboard.
Lastly, if you want to get rid of the parenthesized tooltips, just reload the page.

My Galaxy Tab 3 will only charge from the wall adapter from Samsung
I'm going on holiday soon and we planned to take a USB hub to charge all of our devices rather than take several wall adapters, however when I checked that my 7" Samsung Galaxy Tab 3 would charge, I found that it didn't. After investigating, I found that my iPad charger wouldn't charge it either and in fact the only that would charge it was the USB wall adapter that came in the box with the tablet, even though the port on the USB hub and the iPad charger are rated at 2.1 A (5 V).
When I plug the tablet into to a non-Samsung adapter powered off however, the screen flashes lighter and darker but nothing else happens which seems odd behavior to me.
What is the reason it will not charge by any other means, and is there a solution?

It is not a duplicate actually, as the problem is in the charger.  The "duplicate" post speaks about cable differences.  Please someone un-duplicate this question.

By the way, an explanation of the why can be found at http://android.stackexchange.com/questions/21144/how-much-power-does-a-galaxy-tab-10-1-charger-need-to-supply . It explains the problem for the Galaxy Tab 10.1 at least.

There is more to an adapter than just the current, although kudos to you for knowing that much.  The problems arise due to the fact that the USB-2 spec is for a maximum of .5 A at 5 V without some extra handshaking to ascertain that the device wants and can handle more.  For Apple devices, this is done in a certain way according to their "standard", which is different than PCs.  So, for a PC, you normally need a driver, and it sets up the port for the correct voltages.
Most aftermarket USB chargers are designed to work with Apple devices, and seem to have some differences that make them either more or less compatible with Android devices, but usually require what's called a "charge-only" cable or adapter, that shorts together certain pins of the connector to make the device charge at the higher rate.  These can be bought on Amazon from companies like Mediabridge.  But it's not 100% certain if any particular adapter will work with a particular device.  Unfortunately, some Samsungs won't work at all with some chargers, and work fine with others (I have an 8" Galaxy Tab 3).
If the tablet recognizes the charger at all, it will probably work with the charge-only cable/adapter, I think.  I have one charger where it doesn't even register that it's connected, and it won't work no matter what I do.  But it does work with most adapters, including the one I use for my wife's iphone.
With the tablet powered down (not standby), it should charge at .5 A, which will take much longer.  I'd try the charge-only adapter if you have time to get one before you leave.  Otherwise, you may just need to bite the bullet for now and bring an extra one for the tablet.

Thanks for your answer. This has made a lot of things more clear for me, especially why Apple devices don't charge when connected to the computer until the driver is installed... Also, through experimenting and after reading something online, I can make it charge by only pushing the USB cable in part way. Is this related to the pin idea? I did read that there is some kind of chip in the Samsung USB wall adapter.

I would guess that there is either a chip or some passive circuitry to set the voltage levels of the control wires to something other than simple shorting pins together.  FWIW, I have an LG G2 phone that charges fine from the Samsung charger, and every other charger I have, including iphone. So, it's possible to be more universal, but Samsung may not desire this.  This is one reason I probably won't buy any Samsung phones/tablets in the future.  Oh, and I don't know about pushing the cable in part way, except that it doesn't make sense to me or my electronics mind.  Sounds like a defect.

Yeah, this certainly sounds like it's something Samsung have done to make sure they get as much money as they can with us. The person on the Internet who said that pushing the cable in part way would work suggested it was something to do with the two longer pins at the sides of the USB socket which Samsung use in what I can only describe as their detection mechanism. I don't know if this explanation holds any truth - I'm more interested in software, but what I do know is the method works with several different leads. It's not a fluke.

I don't really even know which cables were the original ones, so I don't know.  But maybe it's somehow shorting the same two pins together that the charge-only adapter does. Anyway, I never heard that particular rumor.  But I have found that the charge-only cable works with some chargers, but not all of them.

Check the power output of your Galaxy Tab 3's wall adapter and see if the power output is greater than the 5V 2.1A power output of iPad charger.
If the Tab 3's USB wall adapter power output is greater than the iPad charger's USB wall adapter then that's likely why the non-Samsung power adapters aren't charging your Tab 3. The non-Samsang adapters aren't putting out enough power for the Tab 3.
I own the Galaxy Tab Pro tablet. The power output of its USB wall adapter is 5.3V 2.0A. My Tab Pro doesn't charge when I use my Galaxy Player 5.0's USB wall adapter, which outputs 5.0V 0.7A.
You could take the Samsung USB wall adapter with you and use it to charge both your Tab 3 and iPad while you're on the road. I only use the USB wall adapter for my Tab Pro to charge both the Tab Pro and the Player 5.0.

Thanks for your answer but the power output of the Samsung charger is 5V 2.0 A, which is what has been confusing me.

I have a galaxy tab 2 and an iPad.  The galaxy tab doesn't charge from the iPad charger and vice-versa.  It might be different with newer models.

Change default in-call & out-call ui or theme
Is there any app available in the store that lets me change the default in-call & out-call ui or theme of my kitkat?

There are several apps available on PlayStore like this or this one. However, you can't change the full "Theme" as such on Kitkat. You can change the look and feel of your home screens, caller screen, etc with the help of launchers (Nova Launcher, Themer, etc).

:Is there any free app with bigscreen options for all contacts?

Why date/time automatic adjustment didn't work?
Recently I went to Italy and bought a pre-paid TIM chip to use while there, because it was much cheaper than the ridiculously high prices of Rogers' roaming.
However, something quite puzzling happened. Whenever I changed batteries (I don't recharge my phone, I change battery to a full one and put the other one to recharge on an external charger) I would lose my date/time, it would reset to 1/Jan/2000. Manually setting it worked, but it was a bit annoying.
I didn't understand why the "Automatic (Use network-provided values)" setting didn't work. I was assuming that the phone would use NTP, and once being able to resolve DNS it should adjust the date/time, but it never did.
Doing some googling I found about NITZ, which apparently Rogers uses but Italian's TIM doesn't. My questions are:

is this the reason why automatic updates didn't work?
is there a way of changing these configurations? (use NTP instead of NITZ for example, or some other configuration that would make the automatic update work, other than installing an app)

Most likely.
If your phone is rooted, you can install an app that will sync the clock using NTP. (Just search for NTP on Google Play: there are many such apps.)

BAT500 is capacitor which hold charge when battery is removed. If capacitor discharge fast then time change to 1 June 2000. I am not sure that problem is with capacitor. You can check for it.
When you connect to network. it take local time zone. So I do not think you need to change NTP protocol.

ACRA init crashing after new rom flash
I recently flashed CM11 on my GS2, it was slimkat 4.4.2 earlier. I believe I did a dirty flash because all my apps and settings were present when I booted it. I used the "recommended" wipe on TWRP.
Some apps gave issues (particularly settings > developer) but wiping app data fixed that. However some apps, watchdog lite in particular is having crashes before it starts (everytime). From logcat, this looks to be due to ACRA init. Clear app data or even app reinstall doesnt fix it. Anyone have any idea?
The lowest exception I see is
E/ACRA    (10931): Caused by: java.lang.NullPointerException

This is for both Watchdog and Travel pocket, the other app that crashes. Any idea if I need to clear files on the SD card or something?
Is this the right forum for it? Or Superuser? or SO?

In my opinion, this is a valid end-user problem. I see no cause to migrate, although SO has more proficient users in stacktracing&debugging.

@onik I actually was thinking (perhaps selfishly) more in the lines of who might have the expertise to answer

How can I copy a NFC badge to my (rooted) Android phone for Daily Usage
For the Cafeteria a school we have NFC badges with which we pay meals or drinks.
I was wondering how is it possible to have the card on my phone? I lost it 5 times last year.
I've tried to copy the data on the card this didn't work so I possibly need to emulate the card on the phone.
Like i said it would be usefull to use it in such way and gives me something to brag about to my non geeky friends. B-)
My phone is rooted, Xposed Framework is installed (when this helps) I have Android 4.1.2 on My Xperia P it's stock.
Thanks in Advance

Not tested myself, but from its description NFC Porter looks like to be your candidate: replaces all identification cards and unifies them under a mobile app. Please let me know if that's what you're after – I will then make it an answer with some additional details.

Thanks Izzi it wasnt wat I'm  looking  for but seems i just haveto get the key of my lunch card.

The app will create a badge nativly and not port it from a badge, what i need to be done. So i will try this app and see what i can achoeve with it. Thanks for your Help

A closer look at their Pro version made me doubt as well it was your choice. Didn't see such an app yet (but definitely got your point). I'm just setting up a list of NFC apps you might wish to check with later (maybe in a few hours). Far from being complete, but if I jump into a candidate you'll find it there.

Depending on the type of card used in your school, copying is not a simple task: The data is may be cryptographically protected and you need to emulate the UID, an ID which gets transmitted by the card early in the communication process. Here are some tips:

At first you need to find out which type of NFC Tag our card is. You can use this app from the Google Play Store
If the card is a MIFARE Classic Tag you might be able to clone the data on it. These cards have had some security problems in the past.
Emulating the UID is not possible by default on Android (related)

But we developed an App which is capable of emulating the UID on some Android devices, for more information see the first answer here
It is also possible that your badge only uses its UID to know who you are. In this case there is no data saved on your card. If this is the case the app for emulating the UID could already be enough to have a badge on your smartphone ;-)

I hope this helps.

HTC Desire X doesn't come up after software upgrade
I want to apologize in advance if this isn't the proper forum for my question; it might be a hardware problem.
I got a message on my HTC Desire X that a software upgrade was available. (IIRC I was on 4.1) I checked if there was enough juice in the battery, enabled WiFi, and downloaded the upgrade. But when I clicked "install" the display simply went black, and the device hasn't given any signs of life since.
What I tried
1. Remove and re-insert the battery
2. Recharge the battery. This shouldn't have been necessary, since it had enough power, like I said. But strangely, even after 24h of charging the power LED remains orange
3. Factory reset: volume down + power button
The battery thing bugs me. It was a good battery (normal charging times) and now it doesn't work anymore. Does the charger rely in the CPU? For instance, if the upgrade really went bad and the CPU doesn't work properly, what about charging.
IF the upgrade didn't succeed, is there a way to get the device working again?

Does the device waken when plugged in? Maybe try booting it in Safe or Force Restart it. Was it rooted?

It isn't rooted. And no, it doesn't wake up at all, not even when plugged in. So how can I boot in Safe or Force Restart (whatever that means)?

Hold down the power an volume up button try that

@user68932 - Yes, I even tried that. (Though the documented factory reset is with the volume down button)

Disable the screenlock on Samsung Galaxy Tab with forgotten password?
I was given a Samsung Galaxy Tab last year for my birthday and I put a password on it but now when I try to get back into it I can't as I have forgotten the password.
I was just wondering if there is a way to disable the screenlock without deleting the files on the tablet.

Try Hard Reset.
To Hard Reset please follow the below steps.

With the device off, press and hold Volume Up, Power and Home button.
Release the Power button when you see the Samsung logo, but continue to hold Volume Up until the recovery screen appears.
Use the Volume buttons to navigate the menu and select wipe data / factory reset. Press Power to choose the selection.
Press Volume Up continue.

Note: These steps clear data from the device. SD card data like your photos and music are not erased unless you choose to format the SD card. You may have to lose some files, but some of them may be able to be recovered.

The question states "I was just wondering if there is a way to diable the screenlock without deleting the files on the tablet."

try multi tools http://forum.gsmhosting.com/vbb/f606/utility-android-multi-tools_1-0-reset-user-lock-gmail-wipe-data-azimbahar-1620378/

The link you posted leads to a method that works on FastBoot. Samsung devices (excluding the Galaxy Nexus) don't have FastBoot.

1 - 6 command do not require fastboot mode.

I guess you're right, I must have overlooked it. (I need sleep.)

Can't shut it off without entering the pin in my case...

If you had its bootloader unlocked before, the following steps are simple to follow.
1. (Skip if done) Flash a custom recovery
2. Reboot into that custom recovery, connect the Tab to a PC (with adb installed on it), open a command prompt and run these commands (bold text is typed manually)

ibug@ubuntu:~ $ adb shell
shell@android:/ $ su
root@android:/ # cd /data/system
root@android:/ # rm -f password.key gesture.key lock*
root@android:/ # reboot

and you'll see your Tab automatically reboots to the normal system, with lockscreen gone.

If you logged in with your Google account, you should be able to see a 'forgot password' option after you have entered the wrong password 5 times. Your Google password will let you reset it.
Though only Medium-Low security passcodes can let you do that. If you do a High secuity passcode it will just enlongate the time to wait until you can try combinations again.

Using IP to ping a real Android device that is plugged by USB from computer
I plugged my Android tablet to the computer with USB cable and looked at the IP of Android device and tried something like ping 160.xxx.yyy.zzz on the computer. There is no response.
I wonder, does being in a huge network that prevent one machine to see the other one affect to
pinging from one machine to another, even they are connected by a USB cable?

Did you connect the Android tablet via reverse tethering over USB or what network does it use?

@onik  i do not know what is reverse tethering.

Just connecting your Android with a PC over USB does not establish IP connectivity. Reverse tethering would be one possibility to achieve that, but there are also other means.

@Flow thanks. is there a mean that not need root access

@Flow i have WiFi both on my Android device and PC within a huge network that i think no device can ping another. But do you think in a small network like a home network, can i ping from my PC to my Android device?

@merveotesi If your Android device is connected to same network to which your PC also connected, then PING should work. But there is no relation between plugging USB and PING test.

@KeshavaGN There is no guarantee that ping works inside any network as long as the two devices are inside it. Especially in large infrastructures, there can be separate VLANs, rules against ICMP packets in firewalls etc.

@onik do you think adb connect can act as a connection like reverse tethering provides?

@merveotesi No, that's the opposite of what adb connect does. It makes an ADB connection to an IP address you can reach on the network, so that you can debug on the device as if it were plugged in by USB.

If your network is correctly setup, and both devices are on the same network then you can ping an Android device just fine. I've just tested it on my office network.
If your network administrator has configured the network such that devices can't ping each other, then obviously it won't work. Similarly, it probably won't work if your phone is on mobile data, since most carriers don't allow incoming pings to devices on their network.
Connecting the device with USB makes no difference at all: pinging is a network operation, so it goes over the network connecting the two devices.

Also worth noting: 160.xxx.xxx.xxx doesn't sound like a local network address. It's most likely the address of the mobile data connection, where ping (and other services) directed toward the device often is blocked by the carriers routers.

Getting files using adb shell
I have a rooted Galaxy S4 device which runs Android 4.4.2 & I'm trying to get the files of an application using adb shell, when I navigate to where my directory is and get the root access in shell and type
cp -R com.samsung.android.hostmanager C:\Useres\S4

I don't get any errors but the files isn't in the destination folder, I did try to use mv which seems to work as the application crashed on my device but even though I still didn't get the files.
Where I'm going wrong?

This won't work because C:\Useres\S4 isn't a path on your phone, it's a path on your PC. Normally you need to use adb pull from your PC to copy files from your phone, but when you need root to access those files, it's not quite enough. Izzy's answer here explains how to achieve this.

Thank you for the explanation, I did that, however, when I installed the adbd insecure and enabled the insecure adbd option, it says at the current status Binary: Insecure, USB debugging: Disabled, even though I did enabled that in the developer options and now when I type adb devices, I don't get my device name!! actually I wasnt able to get my device name after installing the appplication !

Preview Facebook Messenger's message on lock screen
I had this feature on for like 24 hours, but now it's gone. It's when Facebook messages would pop up onto my lock screen and I could see the message without having to actually turn on and unlock my phone. Now I cannot find how to change this.
Where is the setting for this feature?

I have noticed the same thing.
It appears the latest Facebook updates have actually removed the feature as there is no setting in the app for the lockscreen.

Internet becomes abeyant gradually on phone usage
Observed this problem in the following devices:

Samsung Galaxy Tab 2 GT-P3100. - Android JB.
Samsung Galaxy S Duos 2 GT-S7582. - Android JB.
Sony Ericsson Xperia Mini Pro Sk17i. - Android ICS.

When the phone is new or, fresh factory reset, the mobile Internet connectivity is really active. This means, messages in WhatsApp, email notifications from GMail occurs properly in time. But gradually on usage, say 2 - 3 months, these apps take more time to notify new messages when the screen is off. When the screen is ON, messages are received instantly.

Observed only in mobile Internet. (H+ or H - WCDMA auto mode).
Not observed when in Wi-Fi.
Facebook notifications are in-time and this problem is not observed by the app. Only WhatsApp and GMail tend to suffer.

What could be the problem? Any suggestions?

Are all the devices on the same carrier? That could well be the common factor here.

No, different carriers. And the first two HSPA+ and the third one EDGE.

Google Play Store behaving strangely: apps don't install
Lately, when I try to install apps from the GPS, the following things happen:

When I tap "install," the blue "waiting" bar shows up. (I don't know whether there's a better name for it.)
Instead of turning into a progress bar that shows the app downloading, the "waiting" bar just sits there. I eventually hit "stop".
When I go to the GPS on my computer, the apps I have unsuccessfully attempted to install show as installed, even though they're not. (And they don't show as installed on my phone.)

Has anyone seen this behavior before? What is the remedy?
EDIT. The phone is a Moto X, not rooted, on a cellular connection. It started maybe a week ago. I can't think of anything I might have done to provoke it.

A quick tip to help you write questions that people can understand and answer: don't abbreviate Google Play Store to GPS. GPS already means Global Positioning System, so you're likely to confuse readers.

Could you [edit] your question with some more details? What phone do you have? Have you rooted it and/or disabled any built-in apps? What kind of internet connection is it on, and have you tried using a different connection?

Second both comments above. I was already wondering whether one can download apps via satellite #D Additionally, as you've mentioned "before": with your [edit], please include what you did "before" the problem started – or whether it was there from the very beginning.

Moto X, not rooted, on a cellular connection. Haven't tried wifi. The problem started maybe a week ago, with no instigation from me as far as I can remember.

ADB Doesn't recognize device when on Clockwork Recovery Mode
I'm trying to install another rom on my Samsung Galaxy S3 and when in the Clockwork Recovery Mode, the ADB quits recognizing the phone. When I boot to the SO, the pc normally recognizes it, I gave authorization, I have usb debugging on. When I boot into recovery mode, it quits recognizing, thus not letting me upload the rom.

Assuming your computer is running Windows, try re-installing the USB drivers while the phone is in Recovery mode.

Is there a reason that you can't just copy the ROM file/s to your device's memory while it is on? Additionally, I've had much more success with TWRP than CWM. The latter has been much buggier in my experience.

@Chahk Sorry to mention, yes. Windows. And I tried that already with no success. I also tried installing alternative drivers, as instructed in some Cyanogenmod official wiki pages.

@filoxo I didn't know I could reach the same locations from the clockwork recovery as I can when the phone is connected. Could you give some more insight on that? Like where I should put the rom in order to later open from the recovery? Meanwhile I'll check out your suggestion.

I can only really speak for TWRP since I haven't touched CWN in ages. I usually download the ROM.zip file to my sdcard root (which is actually emulated, but it should be accessible while in recovery anyway). TWRP has a Mount option that you should use if you have a physical SDcard that isn't automounted. Then use that file to flash whatever you want. Flashing usually does not delete anything from your data partition (which is where the emulated /sdcard is mapped to). Feel free to chat if you need more info.

I had similar situation with Xiaomi Mi3 W. It was totally working while in OS, but not recognized by ADB when in recovery (CWM). In this particular case it was driver problem. When phone was working normally, it identified itself as MTP device, so Windows had neccessary drivers already installed. But when in recovery mode, it isn't neither MTP nor USB-flash device.
Check Windows Device Manager, it should show some unidentified device (with yellow question mark). If so, right-click it and choose "Update driver", then install standard ADB generic drivers provided by Google (they are labeled "Composite ADB Interface" or "ADB interface" or something like that). Then reconnect the device and see, if adb devices shows anything. It should now display your phone id and say it's in "recovery" state.

Facebook updates every two days
I just bought a Nexus 5 (US version) and for the past 2 to3 weeks I have noticed that Facebook  updates every time I am connected to Wi-fi, I mean I am a developer so I can imagine that updates come out but not so often I assume. Should I just turn auto update off or is there something else that can be done?

Are you a tester for the Alpha or Beta releases?

No, I have never enrolled in a tester program for Facebook!

Facebook does indeed update pretty often with random bug fixes as well as security, performance and stability updates. Often this depends on the company as well as the urgency of the update. Security updates tend to be urgent and are often shipped as quickly as the exploits are patched whilst minor bug fixes might be accumulated first and shipped as a larger update later on.
Automatic updates means less savvy users always have the latest version of the Facebook app and the relevant bug fixes and security patches.
If this bothers you, consider disabling automatic updates.
EDIT
This is the Facebook changelog taken from Changelog Droid

But I mean, is it so often that the updates come in, once ever day, or am I the only one facing these?

Take a look at the changelog I posted above and check if your updates correspond.

https://play.google.com/apps/testing/com.facebook.katana/
Check to ensure you are indeed not in the beta testing.

Unfortunately I am no more an android user.

Perfect voice recognition, but Voice Commands don't work
I'm using a Dutch Nexus 5 with stock Android 4.4.4 KitKat but have the voice language set to English (US). I have the latest files for offline speech recognition for English (US). Google Now, "OK Google"-detection and audio history are enabled, and it all works like a charm. It instantly responds to "OK Google", and transcribes my (English) statements flawlessly.
However, Google Now always starts a search. Whatever I say, it is never recognized as a command. So, whether I say Say 'How are you' in Spanish, Set alarm for 8 PM or just Help, it just starts a Google search on the exact phrase I said. Obviously that's not very helpful. How can I fix this?
(There are only three commands that I've found that do work: call, dial and text.)

Is your Nexus 5 stock, or running a custom ROM with GApps?

Also, you say "English (US)" is selected.  Is this in Google Search app preferences, or system-wide?

I believe the system-wide language setting must be set to English.  I'm searching for confirmation right now.  Can you try this in the meantime?

@Chahk I can confirm. Due to your previous comment I tried changing it to English, and lo and behold voice commands worked. I was just typing it up as an answer as you commented.

Found confirmation: Voice commands only work when the system is set to the following locales only: English, French, German, Italian, Japanese, Korean, Russian, Spanish, or Brazilian Portuguese.

According to Google's help pages on using Voice within the Search app, the Voice Actions only work for a limited set of languages:

For most of these tips, you need to be using Android 4.1+ in English,
  French, German, Italian, Japanese, Korean, Russian, Spanish, or
  Brazilian Portuguese. Some voice actions are not available in all
  languages and countries.

They are not referring to the Search app's "Language" setting, as that only governs language in which search results are returned.  You must change the system-wide Language setting to one the supported locales under Settings -> Language & input.  Unfortunately there is currently no way to use Voice Actions under other locales.  Google however are always improving their Search app, so it's possible that Voice Actions will become available in your country's language soon.

Setting the system-wide language to English (US) (in addition to having the voice search language set to English (US)) made Voice Commands work. I tried this because of a comment by Chahk.
However, I'd rather see a solution where I can have my system-wide language set to something other than English.

Moto g unable to receive SMS after android 4.4.4
Recently I updated my motog from android 4.4.3 to 4.4.4 through OTA after that I can able to send SMS but unable to receive any SMS. Before updating everything worked fine.
I don't know what happened I changed my default SMS app to hangout but no success, even I uninstalled the hangout updates and reinstalled still no success.
When I send SMS from another mobile its not received.
Please help me to get out of this.

Make sure the APN settings are still correct.  Settings -> More -> Mobile networks -> Access Point Names.  Check with your carrier for proper settings.

@Chahk Thanks for your reply. I just resolved by doing a factory reset. All other things didn't worked.

Don't forget to post this as an answer (yes, you can answer your own questions on this site) and accept it, so that others with similar problem may benefit from your research.

Internal space near full but shouldn't be and not according to other stats
So yesterday i was seeing how many apps i have installed and i noticed this...according to which only 248 MB is free. Which looks wrong to me too.

But that is not the case according to storage analyser app...and which i also think should be the case as i know what i am installing and keeping eye on space a certain app takes.

...you can also see it's the same thing (as storage analyser app) in my computer!

So how come..? is it a problem, and what can i do to fix it?

Your SD card/external storage spaces are not your internal app storage. You're looking at two completely different storage areas. Comparing those numbers is meaningless.

sdcard1 is internal storage no?

It's not app storage. It's internal media storage, for music/pictures/etc. Apps are not installed to sdcard0 or sdcard1.

Apps and their data are stored on a different partition (/data) from media (/sdcard0) and removable storage (/sdcard1).  If you are rooted, you can use an app like Disk Usage to check what's taking up space on your internal memory.

in my phone sd0 which is bigger is removable one...and sd1 is that stays with phone.

and whats a difference between disk usage app and storage analyser.

They have basically the same purpose, but you must understand that your phone storage is divided into lots of parts. The only part visible to you, as a normal user, is sdcard1. Apps are on a different partition (data).

ok i found data folder that you said is internal storage. So yea that is almost full...so how can i increase this partition.

@MuhammadUmer Check some of the questions under the [tag:insufficient-memory] tag.  Some good advice there already.

Phone unusable whilst charging
I have a fairly old samsung galaxy S2 android 4.1.2. In the last few weeks, it has been behaving really oddly when plugged in to charge. The 'desk clock' page flashes up every few seconds of its own accord, and sometimes the 'voice command' page. When I try to use the phone, I can only operate it for a few seconds at most before one of these things flashes up, which means I have to come out of it and try to get back into what I was doing (usually just for the clock page to come back up again instantly). It's getting worse, to the point I just can't use it when plugged in.
I appreciate the answer is probably eventually going to be to buy a new phone, but was wondering if anyone had any ideas or suggestions in the meantime. Many thanks.

These are often triggered by magnetic sensors inside the phone. Is there any sort of magnet near the charger? Otherwise, you may have a defective charger or charge port that is tripping these sensors.

Check if your charger's current or voltage is not higher than what your phone is supposed to accept. I had similar issues before with generic (chinese) Android chargers.

Can "find my phone" still track my Samsung Galaxy S4 after factory reset?
Just lost my Samsung Galaxy S4 this weekend. If the thief has removed the SIM card and reset to factory mode, does the "find my phone" app still work or does it also get removed?
Been trying to track it but nothing happens. Can I find it if the thief has put his information into the find my phone app that comes with the device?

No, the app will be removed along with all other apps and user data. If you root the phone, it's possible to install a tracker as a system app, such that it will only be removed if the thief flashes a new ROM, but any app you install from Google Play or another app marketplace won't be able to do that.

Samsung Note 3 Phone - Clicking camera button fails to take picture
Frequently, I see x1.0 in the middle of my camera preview screen, to the left of a small white box.  I'd like to know what exactly that means, but it seems like when it is there, I cannot take a picture.  Absolutely nothing happens when I click the camera button.
I have taken lots of photos with the phone, but sometimes I fall into the above scenario, and it seems like the only thing I can do is to back out and restart the default camera app.

I would guess that's a zoom indicator. Does the Note 3's camera app allow you to pinch to zoom? Maybe the app is getting hung up for some reason and misinterpreting your tap as part of a pinch gesture.

I just confirmed with the pinch gesture - and can go from x1.0 to x4.0, and at least this morning, every press of the camera button has taken a picture.   Could it have something to do with auto-focus, or the camera still trying to focus?  Yesterday, I was taking a picture of my driver's license, and I've also had it happen at events where there was a lot of movement.

Could it be because I'm shaking a little bit?  I've seen the box turn green and red too, which apparently means it's in focus.  I was just showing 3 guys at work, and they also seem to be baffled.  It will work fine 90% of the time, but once it goes "bad", I need to figure out what it wants to "be happy" and take the picture.

I knew why you have x1.0 appeared on the screen and can't take photo. I had the same problem and found out the answer. If two fingers touch the mon, it will appear x1.0 in order to zoom, and if there is still one finger on the mon and haven't move away, you can't press the camera button until all the fingers have moved away from the mon, the camera button will function again!

USB connection unreliable while tethering
Device: Galaxy Nexus
Android: CyangenMod 11.0 (Android 4.4.4)
The IT department of my company doesn't support access of Mac devices to its network, but it does for Android devices. So I would like to connect my macbook (Mac OS X 10.9.4) to the internet by tethering my phone's Wi-Fi connection. Bluetooth tethering is reliable, but rather slow (max 200KB/s download speed, in reality it is rather something like 80KB/s).
So, I tried to use the USB tethering with the help of HoRNDIS (release 5), which is magnitudes faster (22MB/s) than Bluetooth tethering. However after a while (some minutes), the connection is lost. To restore it, I have to unplug the USB cable, plug it in again and retick the checkbox 'USB tethering' on the 'Tethering & portable hotspot' page in the 'Wireless & Network' settings.
In order to solve this problem, I tried the following:

Enable 'Android debug mode' & 'ADB over Network'
Screen always on

Unfortunately, these attempts didn't work.
Does anyone have a similar problem or workaround?

I'm having the same problem. I've tried with HoRNDIS (rel 4 & 5). USB tethering will drop after a while and come back. I'm not sure if my Galaxy Note 2 having problems with the USB cable. But now you've posted this, I'm pretty sure it's not because of the USB cable. I've used the Xiaomi Redrice phone for USB tethering before, and it's really good. There is no data dropping. I'll look for a workaround.

I used different USB cables, but the problem persisted. My USB socket seems to work well, no issues with charging or with data transfer.

I faced similar lost internet connection issues with galaxy y tethering. Had to unplug and plug in the cable; again select tethering. However, i noticed that orientation of the cable just outside the socket mattered. There is room for movement even after usb is plugged in the phone. In this instance, when i so arranged that the usb cable is as lateral as possible to the phone midline(had to use anatomy); there was no lost connection.

I use USB extension cord with iphone 5 and Windows 10 PC and have same problem. After a few minutes the internet sharing cease to function and I have to unplug and plug cable. But I noticed that it happens more often if I physically move USB cable. It seems that physical connection in USB port is broken for fraction of second and this causes loss of internet sharing.

Make sure that you disconnect the other network connections / Ethernet while USB thether... I just went through 5 days of page hangs, and then I switched my ADSL box (it was disconnected anyway) and it put the tether on a new network name called network 5 and all the pages come through now.

Can Asus Nexus 7 WiFi support a Huawei E3276 4G usb dongle SIM holder to achieve telephone functionality?
I could connect (with an usb adapter) a Huawei usb dongle that I normally use with my laptop computer and contains a SIM card for mobile internet and phone functions like SMS and phonecalls, but it doesn't seem that android (4.4.4) with my Asus Nexus 7 WiFi edition recognizes the device. Can it be done, or should I investigate other ways to enable mobile internet and telephony for my Asus Nexus 7?

Did you go forward with this and make any progress?

I didn't test it more. I think it's feasible to make it work with software interface. First I must fix a random bug that reboots the thing. Thanks for comment!

Is it possible to share file with one using NFC and another using bluetooth?
May I know if it is possible to transfer file from one phone using NFC to another phone using blue-tooth?
I know it is possible to transfer file from one NFC to another NFC. Also, it is possible to transfer file from one blue-tooth to another blue-tooth.

So you want to get on a plane and arrive in a car?

If I've understood correctly, you have one phone with NFC but no Bluetooth, and another phone with no NFC but Bluetooth, and you want to send a file from one to the other.
That can't work. NFC and Bluetooth are completely unrelated, they can't communicate together. If you want the two devices to communicate, they need to both use Bluetooth, or both use NFC, or both use Wi-Fi. It's as simple as that.

Is it possible to control the strength of the vibration of the phone when ringing?
When the phone is ringing, is it possible to set such that it gradually increase the strength of vibration instead a predefined strength of vibration? (When the vibration mode is turn on but the ringer tone is muted)
The concept is something like the 'gentle alarm clock' that will wake me gently, rather than jolting me from my slumber. (It work by having the alarm that gradually grows louder and louder until it becomes impossible to sleep through.)

No. Android doesn't give apps a way to control the strength of the vibration, so you won't find an app that can do this for you.
That said, there's an app that claims to be able to change the vibration strength on Nexus 4 and Nexus 5 phones, using a device-specific method that requires root. Some users report that it doesn't work at all, but if it does work and you have a supported device, and your device is rooted, you may be able to find an app that does what you want.

Is it possible to know how far away another phone is using bluetooth?
When connecting to another phone using bluetooth, is there any way to know how far away the other phone is (would be better if it can tell me the exact distance even though a estimated distance is fine with me)?

No more precisely than you already know: if it's connected with Bluetooth, it's probably less than ten metres away. It might theoretically be possible to use the round-trip-time between the two devices, and the finite speed of radio waves, to compute the distance, but in practice at these small scales the travel time is less than the latency in the Bluetooth stack. Radio waves take about 3 ns to travel a metre, which is about the time it takes a 2 GHz processor to execute one instruction.
You can get a reasonable approximation using the received signal strength indicator (RSSI) that the Bluetooth stack tells you. This number is available to apps, and it tells you how "loud" the remote endpoint's radio signal appears from the phone. A more positive number means the devices are close together; a more negative number means they are far apart. Some apps use this number when offering a list of devices to connect to: sorting the list by RSSI puts the closest devices at the top.
However, this is only an approximation. The RSSI doesn't simply vary with distance: it's affected by other factors. Reflections from other surfaces and objects can make it increase or decrease, and having objects in between the two phones makes it decrease. For example, if you're holding your phone, and the other device you're connecting to is behind you, so that your body is in between them, it will appear further away. Similarly, if the device is in your pocket or bag, it will appear further away. Even if you stay in the same place and nothing moves, the RSSI will still fluctuate a lot, because of interference from other radio sources.
Bluetooth LE beacons such as iBeacons use the RSSI to present an approximate distance, but it's only to categorise as "far", "near", or "immediate" (nearly touching), because you can't really get more accurate than that with RSSI.

Is it possible to make my phone as a remote shutter?
Is it possible to set a android phone to act as a remote shutter that can connect multiple devices (phones and/or camera) via bluetooth to take photos?

I don't know any cameras with a Bluetooth shutter interface. Are you sure yours can do this?

These types of remote shutters usually rely on a more standard 3.5mm jack to plug into the camera. The only Bluetooth solution I know of is this:
http://www.amazon.com/Satechi-Bluetooth-Wireless-EOS-D2000-Compatible/dp/B00ANWQMWK
but unfortunately it looks like its only for Canon DSLRs with a hotshoe.

Yes you can use your android phone to act as a remote shutter for certain digital cameras. Helicon Remote, Remote Release and DslrDashboard  are popular apps that uses USB OTG cable to control various Canon and Nikon DSLRs. EOS Remote is an app from Canon tailormade for its EOS series for DSLRs but it makes of use of wifi though. The only application with description that makes use of both bluetooth and IR to control your camera is DSLR Remote Plus by bitshift. Try the free version available in playstore to check the compatibility with your devices. If satisfied buy the donate version and help the developer.

Restore phone and keep whatsapp number after changing sim
I am going to restore my phone and I want to keep my whatsapp number.
The thing  is, after restoring I am going to use a new number.
Restoring my phone means I will have to reinstall whatsapp, then I will be asked to verify phone number. My old SIM is not working anymore.
What should I do to keep my old whatsapp number?
I am using samsung galaxy nexus android version 4.2.1

Insert the new SIM into the phone.
Go to Whatsapp settings > Account > Change number
Validate the new number.
Go to Chat settings > Backup conversations
Follow the instructions here to restore the conversations

Try this:

Backup your WhatsApp from old phone using Helium Backup. Follow the
instructions for backing up WhatsApp (or any other application for
that matter).
Once the backup is complete, you'll find a folder named "Carbon" on
your phone storage.
Copy this folder on your PC.
Install Helium on the phone after restoring and get this backed up folder on your
phone and place on the same location on the storage.
Start Helium and backup WhatsApp using the "Restore and Sync" tab
available in the app.

If you are not rooted, you need to connect your phone to PC using USB cable to start the backup. Follow the instructions given on Play Store page.

How to import names+phone numbers into my Android smartphone (a Galaxy S3)?
I have an Android Galaxy S3 phone and I have a two column lists of names + phone numbers on my hard disk, and a Google account, and am a capable programmer and software developer. How can I import the phone numbers into the phone?

No programming is required in this case. You need to make little changes to you text file so that it looks like below:
================
Name,Phone
Rakesh Patel,9825798257
Ramesh Patel,8758965854
==============

First row should be column header: Name, Phone
Name and number should have a comma as a separator.
change file extension to *.csv

Then Go to Google contacts ==> click  More and select Import and upload the CSV file.
This will import all your contacts to Google account.
Then add same google account to your Device (if not added already).
If Sync option is already enabled, your contacts, calendar etc. will start syncing with Google account data when your device is connected to internet. (If sync is disabled, you need to enable it first)

Samsung Glaxy S5 Wifi Not in Range
I have Samsung Glaxy S5 device with some other devices. The Wifi is working every device except in Glaxy S5 device. But when I go to Wifi settings I see 2 connections 1) MyWifi 2) NVRAM Warning: Err = 0x10. When I select MyWifi and put the password. It says 'Authenticating' then it will show 'Not in Range'. Tried everything but nothing is working for me.

It might help to be a little more detailed on the "everything" part on your question – or we can only suggest to try "something other" ;)

@Izzy, I mean reboot, disabled MAC filtering, etc

That's something. Now for the "etc", please :) Honestly: please be as precise as possible, or you'll end up in a loop with people suggesting something, and you saying "I did that already" (and please, [edit] those details into your question: with the comments list getting longer, people will stop reading them). There are many possibilities, e.g. removing the AP and re-adding it in your configuration, doing a complete factory-reset, and more.

Is it a 5GHz access point? There is a known problem where some phones running recent android builds cannot access 5GHz APs. I have this problem on my Nexus 4.

Is it possible to run applications with different locales (languages)?
I want to run some applications in one language and the rest with the others. Specifically, I'd like to run maps in Russian (I really don't need names transliterated to Latin) and everything else in English (Russian translations are usually very poor and I just cannot understand what the app wants to tell me. English translations are usually good enough for me to understand).
I run stock android 4.2.2 on rooted Texet X-basic tm-4072. The solution involving Tasker does not apply for me because Google Play says Takser is not compatible with my phone. There was an application for this, but now it's outdated and I don't know how to reach the author (he suggests to send the newer version to those who write to him).
In desktop Linux I'd simply run app with different LANG value, does something like that work for Android?

A hint concerning Tasker: You can grab the .apk from their website and see whether it installs nevertheless. (and before you ask: no idea for the rest, sorry – at least not if the apps don't support it by themselves: some apps let you chose the language to use, and just default to "system")

According to the recent announcements Android 13 will be able to change the locale/language for every app.

This module for Xposed Framework should do the trick if your device is rooted.

Install Xposed Installer.
Run Xposed Installer and use it to install Xposed Framework. It's a two-tap operation followed by a reboot.
Find the App Settings module in Xposed Installer, install and enable it. Reboot device.
Click the module in Xposed Installer to show its GUI. You'll be presented with available features, including changing app locale.

This way does not seem to work for me: enabled, settings changed but still english

Locales are programmed on a per app basis,
For example, if i developed an application with hard coded string characters in English, the hard coded characters will always be in that language...
It requires translations, string's of characters to replace per locale...
If you are sure it supports the language then it is hypothetically possible, however the developer defines the the default language...
You can manipulate or MOD the APK with something like APK Editor or APK Tool to set Russian as the default locale in the application.
The problem i think you are having is that your specific app needs an update to one with a larger selection of translations.

This app Xposed App Locale helped me to change locale per application.

It's definitely worth adding that, like any Xposed module, this suggestion requires [tag:root-access] and involves big modifications to the Android framework on your phone.

Get CM safely on incompatible phone
My phone isnt compatible with Cyanogen mod how can i safely install CM?
Xperia P 4.1.2 rooted.

There are basically two options: help to get it supported, or look for an unofficial build.
I wrote some notes about helping to get Cyanogenmod supported on your device in my answer to Why isn't there a Cyanogenmod stable ROM for my device?. If you already have the specialist skills needed for ROM porting, you can do this yourself, but even if you don't, other volunteers at the Cyanogenmod might be able to achieve it with your help.
The only alternative is if there's an unofficial build. Because Cyanogenmod is an open-source fork of AOSP, anyone with the skills and the hardware can port it for their device and release that build. Unofficial builds can commonly be found by searching the XDA-Developers forum. They don't have the same quality control, support community, or updates as regular CM builds, and of course with an unofficial build the risk of the ROM being backdoored (so the porter can access your phone illicitly) is much greater, but if you're willing to take those risks it provides another way to get Cyanogenmod.
If there's no unofficial build, or you don't like the risks I've described, and you're not willing to help get your device officially supported, then you can't use Cyanogenmod on your device.

Used (probably) inappropriate charger, touchscreen went crazy, permanent damage?
I used a plug with USB output than may have been inappropriate (output DC5V +/- 0.20V DC500mA +/-30mA). While it was plugged in, the touchscreen stopped working properly (touching one part of the screen would trigger another), I guess because the voltage was wrong? Is there any danger that I did some permanent damage to the phone or the battery? It wasn't plugged in for long.

I'm not really sure what you want us to tell you. If the problem went away after you unplugged and rebooted, then it's all good. If it didn't, then your phone is broken. We can't tell which of these is true because you're the only one with the phone.

No permanently damage I'd say. Sounds exactly the same like a case I had using a HTC charger on a Motorola device. It's not the voltage causing that, but most likely a slightly different use of the additional "X PIN", see: Why does my phone have erroneous input when connected to a non-OEM power source?

You can be 99.9% sure the touchscreen is fine. Battery wasn't damaged too. If the touchscreen still behaves erroneously after unplugging, then rubbing it with a soft cloth should help.
This is a common issue with cheap chargers. It indicates that charger may not be safe to use with any device - it may catch fire or explode. Prolonged use of such chargers can degrade battery performance faster than charging with a high-quality charger.
It wasn't a voltage problem - all USB chargers have the same voltage and you can use any charger with a plug that fits. Charging speed may differ, though - high-end smartphone and tablet chargers are faster than regular mobile phone ones.

Charging speed doesn't affect the phone, since the phone regulates the amount of amps it can take, not the charger. So if the charger can supply 2A and the phone needs 0.5A, it only takes the 0.5A. Also, if the charger can supply only 0.5A and the device (tablets usually) requires >1A, it simply refuses to charge. The power quality and consistency, however, is very important, and is the problem with cheap chargers as you mentioned.

@onik From my experience phones will charge from low amperage chargers at the rate charger provides, so maybe it depends on chargers and/or phone models. Also, if USB data pins aren't shorted phone will never draw more than 0.5A because it could be a USB host, not a charger.
