Switching between my profile on Google+ and a page I manage
I have a Google+ account. I manage a page there, too. But how to switch between them using an Android device that its version is 4.2.2?

In the Google+ app, tap the "hamburger" menu in the upper left. It should show your cover image, your profile image and name, and a menu of options: Home, People, Photos, etc.
Tap the downpointing arrow next to your name.
You will probably1 see an option to "Select Google+ page" with a right-pointing arrow. Tap that.
Now you should see your page(s) available in a menu. Tap it.
You are now using Google+ "as" that page.
To go back to your personal profile, follow the same steps, but choose your profile where before you chose your page.

1If you've done this before, then the page you used before will be listed here along with "Switch Google+ page" (if you have more than one page to manage). This also assumes that your Google+ account is set as a manager/owner of the page in question.

disconnect gmail when cheked in from another mobile
I checked in to my g-mail using a friends mobile.
Now that I exited from my g-mail the friends phone seems connected to my Google account. How do I disconnect my account from that phone? now I can't check in from my own android phone , please help urgently.. thx

There are three ways:-

If you have access to the phone (or trust your friend to do it), just delete your Google account from your friend's phone. In the main Settings app, under Accounts, find Google in the list and click on it. Then click your account and click Remove account.
If you've switched your Google account to use app-specific passwords, then you can simply revoke the Gmail password you used to sign in on your friend's phone. Nothing else will be affected.
If you can't wait for your friend, and you're not using app-specific passwords, then just log into your Google account from a web browser and change your password. It will sign out on all the devices and you'll get a prompt asking you to enter the new password.

That said, there's something that doesn't quite add up. It's possible to be signed in and use Gmail from more than one Android device at a time. Signing in on your friend's phone shouldn't make your phone stop working, so it could be a coincidence, which means that signing out on your friend's phone won't fix anything.

Stop Android connecting to external USB storage device
I have a car adapter with 2 USB ports, 1 of the devices is a continuos recording camera (with an SD card in it) and the other device is my Android phone (Sony Xperia, Android 4.3). However, when I connect both devices to the adapter the continuos recording camera stops recording and shows 'external storage' on the screen, and there is no way to stop this behavior on this device. In my Android device I can see no messages, but can indeed see the other device's SD card. There are no popups in Android when I connect to it. Is there any way to stop Android from detecting this other device?

Could you describe this "car adapter" further? It's pretty unusual for it to be set up with one device as the host and another as the peripheral.

Also, what are you actually trying to connect together? Do you just want to power all the devices from your car, or do you need a data connection?

The car adapter is a standard el cheapo chinese adapter with 2 USB ports, like this: http://i.ebayimg.com/00/s/MTAwMFgxMDAw/z/KikAAMXQC-tS~bCl/$_35.JPG?set_id=8800005007  I didn't expect (and want) the 2 devices to interact, but for some reason they do.

Use a needle or a pair of needle-nose pliers to break the data pins on your adapter, so they won't connect to the device. Breaking the data pins doesn't inhibit the adapter's ability to supply voltage across the power pins. Alternatively, it might be easier to cover them with a small piece of insulating tape; the easiest way to do it will depend on the shape of the adapter and what tools you have to hand.
Of the four pins inside a USB plug/socket, the middle two are the ones you want to cut off or cover. Be careful not to damage or cover the two outer pins. It should go without saying that you should do this while the adapter is not connected to anything.

Thanks, I've thought of this, but I would rather have a software based solution if possible. With Android being such an open system, I was hoping it should be possible to disable this functionality.

To be honest, it's a really bad idea to have the data pins wired that way on a power adapter. I don't like to think what it's doing to the power negotiation between the phone and the camera.

I'd also replace the charger...

I tried to put a piece of black electrical tape on the middle 2 pins, but then it doesn't work at all anymore. Maybe I'll have a look next time for a new charger...

I've invested 100 baht in a new charger, and the problem is gone. :)

If the problem is solved, then answer your own question and accept that answer. That way, other users won't keep posting suggestions you're not going to try.

Allthough error INSTALL_FAILED_ALREADY_EXISTS have gone, the telephone still not rooted. [-] Failure.

The problem isn't that a file already exists at that path: it's that the app you're trying to install is already installed on the phone. Have you previously tried to install SuperUser as a normal app? You need to uninstall it before you can root the phone. Uninstall it in the usual way from Settings → Apps.
In addition, the Motochopper exploit only works up to the 4.2.2 firmware for the Galaxy S4 (and only S4 variants with the Snapdragon chipset, not Exynos-based ones). If you've already updated to 4.3 or 4.4, this exploit can't work. You need to use another method, for example unlocking the bootloader the conventional way (though if the phone is carrier-branded the carrier probably has disabled unlocking the bootloader).

INSTALL_FAILED_ALREADY_EXISTS have gone, thank you. But still can't root. See update, please.

How to check what's wrong while my phone starts? How to get logs?
My phone does not start up. It shows splash screen, but it doesn't load a system. How can I check what's wrong?
EDIT: More info: the broken phone is Galaxy S+, it is currently rooted, I installed CM 11 on it. I don't know if it is my blame I think not because I haven't done anything special on this phone for some time (it has worked correctly about month with all those modifications installed). I haven't given access to root to any of installed apps. Reinstalling system works, system starts but when I restart my phone it doesn't work anymore (until I re-install it again).
Maybe is there some way to save logs on external sdcard?

What version of android? What was the last app you installed prior to the issue? What was done to arrive at this point? Can you go into Recovery? Did you install a incompatible kernel? A lot of vital information left out, thus making this question too broad to answer. Perhaps, re-edit your question to include the above answers to my questions in order to narrow it down specifically.

Install the android sdk and plug in your phone.

Go to a command prompt
change directory to to your adb folder
Type adb logcat > logcat.txt

this creates a text file in your adb folder and would tell exactly why your phone isn't booting.

"- waiting for the device -" --> computer doesn't see my phone. Another problem is that when I plug my phone before pressing power button, on the screen appears picture of bettery and then I can't turn it on.

Anyway, does it have chance to work? I mean: the problem appears before starting android (I think). ADB is android soft

adb is active even while the phone is starting to boot. So, try a few times and adb logcat should be able to provide some relevant output. But I doubt the logcat is actually going to help you. Get the support tools for returning your phone to stock and re-flash the stock rom when your phone is put in download mode.

EDIT: After update to the question my answer is not valid for this case, I thought that the phone wasn't booting right after flashing new ROM. Leaving my old answer in case someone might have the issue I have described earlier.
As far as I know until your phone boot there is no way to check logs.
Though I think your phone might have some problems booting due to some cached information which wasn't wiped before flashing your ROM. I had similar issue and wiping caches fix my boot-loop on GalaxyS4 - Cyanogenmod 11.
All you need to do before flashing your ROM, is to turn your phone in recovery mode, then wipe cache, and dalvik cache, after that you can flash your ROM. I can't tell you exactly how to do this because I don't know which recovery you are using.
This operation won't delete any of you personal data, only some apps cache, after rebooting your phone should start preparing apps and then boot normally. In case its still not working you might try to wipe cache and dalvik cache again and additionally make factory reset, this operation will wipe all your data from your phone so if you got important information on your phone make sure its the last possible solution, after factory reset flash your ROM again.
Also some custom roms are not working correctly with every recovery, so make sure you are using supported recovery.
PS. Also I advice you checking this forum: http://forum.xda-developers.com/ for any information regarding flashing roms/kernels etc.
Disclaimer: Though this worked for me, and I think it should work for you too, I am not taking any responsibility for any damages to your device, nor lost data.

I added more info to my question. Sorry that I haven't said that at once :P

Simplest way to transfer files from PC to Android device (wireless)
What's the simplest way to transfer files (often around 100 MB) from PC to Android device, with wireless connexion ?
Should I use an application for this?
Remark 1 : I want to set "wifi=off" after the file transfer is done, because I never use it except for the file transfer. Moreover I really would like to do a direct transfer PC -> Android device ; no Dropbox or similar tool.
Remark 2 : I have a Samsung Galaxy 3.6 Player YP-GS1CB (limited to Android 2.x as far as I know)
Remark 3 : If possible, I would like to be able to see the Android device's microSD card filesystem from computer, access to subdirectories, copy files there, etc.    Would a FTP server on the Android device be a good way to do it ? If so, with which app?

There's a ton. You could use one of the cloud sync apps (Dropbox, Google Drive, Copy, etc.), you could use one of the Android remote control apps (Airdroid, etc.). Even some of the file managers have a way to get to shared drives on your wifi network (ES File Explorer, ASTRO, etc.) Did you try searching on the Play Store? Also, simplest is pretty subjective; we prefer questions that garner objective answers.

Thanks @AlE. I added some remarks at the beginning of the question in order to make it more precise.

Airdroid can perform file transfers and it runs on 2.2 and above.
All features:

SMS: send and receive individual or group messages.
Apps: Import and export .apk files.
Files: Manage files on Android and transferring files between Android and computer.
Photos: View and manage photos on Android and transferring photos between Android and computer.
Music & Videos: Play and manage music & videos on Android and transferring them between Android and computer.
Ringtones: Set music as ringtone and export any ringtone.
Contacts: View and edit all the contacts.
Screenshot: View the real time screen of Android devices, take static screenshots. (root required)
Camera: See through the lens of both front and back camera, also supports flashlight.
URL: Push url to Android and open automatically open it with Android browser.
Clipboard: Share clipboard content between Android and computer.

I've been looking around for ages after an adequate solution and was frustrated to find no official apps that provide this functionality.
Link to PC changed everything.
It's a Microsoft app that allows you to use your phone from your PC.
It supports a wide variety of features, including screen-casting, file-transfer by drag and drop, send and receive messages and phone calls and more.
I might sound like Microsoft's salesman but I have no affiliation whatsoever, I'm just a fan of this app that made life so easier for me.

I developed WiFi FTP Server, which should solve your problem. I would recommend that you put the phone in wifi-tether mode and then transfer files.

Poor Performance at Low Battery
I'm having an issue where my phone gets sluggish and non-responsive when the battery level gets to around 35% or less.  Apps will freeze, it will take the keyboard a long time to appear, and the unlock pattern will sometimes not show up at all when turning the screen on.  Any ideas would be appreciated.
Phone - Galaxy S3
Carrier - Sprint
Android version - 4.3

I guess you are using stock Samsung firmware. If so, probably you enabled Samsung's "power saving mode".
Go to "power saving mode" settings and unchecked "CPU power saving" options.

I double-checked and the power saving mode has never been turned on.

Do you have a rooted SGS3? Also are is it installed any battery/power savings app?

It is a stock SGS3 without any power saving applications (ZDBox is installed but the power save feature is turned off, I'll disable the battery service entirely just to be safe).  Perhaps I should just try a full backup and factory reset?

Offline Google Maps with favorite places and POIs
I use Google Maps on my PC and have some favorite places added there. On my phone, I want to use an offline map. On my old phone, I used RMaps with whole city maps downloaded with Mobile Atlas Creator and manually added favorites and POIs on it. Now I bought a new phone and found out that RMaps is no longer available.
I'd like to add favorites/POIs to Google Maps and make sure they will be available with a whole city map when the phone is offline. But I don't want to be somewhere and open Android Google Maps and find out some tile for that area wasn't downloaded.
The best solution I see is to download the whole map from Google Maps or OSM and store the map on the phone and use some app that's able to open this offline map file and at the same time sync favorites/POIs with Google Maps.
I tried OsmAnd, but when I create a POI on it, it fails due to some authentication error. It's not trying to connect to Google, because other apps are able to sync with Google Apps. But there's no setting to add login data or create a new account.
Could somebody suggest a way to properly handle offline maps and sync favorites with Google Maps?

Does this answer your question? Is there someway to make "My Maps" in Google Maps available offline with location markers?

You can add offline maps to Google Maps by setting the view to the region to want to store, then searching the phrase "OK maps". For custom maps, you currently need the Google Maps Engine app, AFAIK. Not sure if it had offline storage at present.

I have tried this "OK maps" trick, it doesn't work. When I zoom on an area I never soomed before its zoomed tiles aren't available.

Looks like there's no way to synch Google Maps favorites.
I discovered OsmAnd stores its favorites in /osmand/favourites.gpx. It's an XML file, each favorite has a name, category, latitude and longitude. In Google Maps, anywhere we can right-click and select "What's here?", it will show top-left the coordinates of the place right-clicked.
The solution I found was to manually handle my favorites. In OsmAnd, we go to Favorites and click on the middle-bottom button to import any new record in that file. When I need to add any new favorites, I'll just edit the file and import it again. This way, I'll always have control of them and can backup the file.

How to backup locked apps?
Device: Huawei Y300
Android: Jelly Bean; no root
I'd  like to backup  apps (their APKs). There are some apps that can't be backuped with ES File Explorer. AppMonster marks them as  locked, and I've read that that's a safety feature. Some apps have this, and they can't be backed up by many backup apps that I've tried so far.
How can I backup these locked apps?

I would suggest using Titanium Backup. It has extra features for rooted devices, but normal app and data backups work fine wihtout root.

Same apps don't work for me.

What apks are they?

What does leaving your device off for a while do?
This page: What should I do before I try advanced troubleshooting says
3) Keep your device switched off for a while. Make sure you remove your SIM card (and the battery and SD card as well, if they are detachable) and wait about 30 minutes.
What is the purpose of that?  What is it expected to accomplish?

Have you switched off your computer for a while? The point am making is to ensure 1) memory will not hold residue after a period of time and 2) in context of smartphone/devices, to de-register the sim card from the network as in not actively scanning...

What do you mean "memory will not hold residue".  A simple reboot clears all the RAM and starts fresh. 2) Is all that necessary to "de-register" the sim from the network? If the device is off, it doesn't remain in contact with the network right?  I can see that someone might recommend this step in an attempt to do that, but it seems to be more than is necessary.  It almost sounds like an attempt to separate and air cool the components.

for 1) static discharge. What is your point of asking the question - you have troubleshooted a PC?... same thing applies.

@t0mm13b The point of asking the question, is that the answer on that page had a strange recommendation with no explanation as to why.  No, I've never attempted to discharge static from a computer by leaving it off/open/out for a period of time.  Doing so could actually increase static charge (depending on the conditions of the environment).  When working on a computer I've always discharged the static by 1) grounding the power leads, 2) grounding the case.  Takes a couple seconds and done.  I don't understand the intent of leaving a phone in this state for this length of time.

The question is too broad in that there is no right or wrong answer and is subjective, to each and to their own opinions.

@t0mm13b I would have left a comment on the answer, tagging Sid and waiting for him to speak for himself, but the site won't let me do that.  The reputation based privileges can be so frustrating.  Asking a question here was my only option.

@t0mm13b I've been a constructive member of StackExchange for 2 years, but I don't spend all my time here so I only have 283 rep spread out over 8 sites. I can usually find help without asking duplicate questions.  I really wish all the different sites weren't so schizophrenic with their rep and allowed me to ask a clarifying comment, or let me reward others by voting up on a question or answer I found useful.  Do you have a better way for me to contact Sid for clarification?  Maybe you could tag him on a comment on that answer, with a link here. It's not great, but what else is there?

I, too, suspect that Sid is advising you to separate and air-cool your phone's components.  Removing and later reinserting the SIM and SD cards will also help to ensure that they're inserted correctly.

Backing up broken android device
I have an android device running KitKat 4.4.2 (not rooted; developer stuff turned on) and I shattered the digitizer. I can still see what's on the screen but I can't interact with it1. I tried using adb to back it up, but I was unable to press the "confirm" button on the screen. Is there anything I can do now [i.e. without getting a USB OTG cable and a mouse]? I'm comfortable w/ ADB and the command line if necessary.
1I could get an OTG USB cable and connect a keyboard/mouse and use that to install a backup app, etc. but I'm hoping there's an easier way.

Install a vnc server on the phone through adb and then you can connect to it.

Can you suggest a VNC server that you can set up and run without touching the screen?

I opened my phone and tore the power circuit, can it be joined back?
I wanted to reseat my phone speaker because it wasn't working. In the process of dismantling my phone, I tore the power button's circuit. What kind of adhesive can I usually use to join it back together? Or I am pretty much screwed?

That may describe to you what happened, but it is not enough information to know how it is damaged. Did you peel off traces, just pop the switch off? or is this plastic damage?  Do you have a picture?

If the power circuit is torn, it's impossible to join it back. And definitely not with adhesive!

rooting galaxy s4 GT-I9505 with android 4.4.2 kitkat
I tried to root phone according to instruction.
And it was ok. It seemed that my phone successfully rooted.
But when I run root checker it showed that I don't have root access.

Flash super SU zip in recovery. Open the app and update the binaries. Then try root checker again. Have you super su installed, can you open it and update the binaries? Root checker needs to be granted super user access somehow, that's done via superSU

Easy way: Wipe your phone and try again from fresh stock.

but only do this if in [adb shell] you can execute "su" successfully.

Can the WhatsApp group icon or title be locked?
Is there a way for a WhatsApp admin to lock the group icon and title? As of this time, any group member can change the group icon or title.

Check out the new answer added - now it's possible

No. It is impossible using the standard app.

What do you mean by "standard app"? Are there parallel apps from WhatsApp or something?

Of course, there is Whatsapp+ an app that let you customize various settings of Whatsapp. But it is an apk, and you have to replace the official whatsapp app with this one.

2018 and it's possible!
WhatsApp admins can stop the members from editing group info. The feature appears to be recently added to WhatsApp. While searching, I found that it is functional since version 2.18.135. What I have installed right now is 2.18.141. So, it should be rolled out to everybody by now.

Open group info.
Look for the new option "Group Settings".
Change the Edit group info setting from All participants to Only admins.

I can also read some sites reporting that WhatsApp beta also has a new option where all members can be muted. So, essentially working like a telegram channel where only admins can send messages. Good times ahead!
PS: This question was asked long ago. However, it still ranks well in the search results and I believe that it needs to be updated for the changes WhatsApp has made recently.

My phone not registering to 2G (GSM only) network
I am using a Sony Xperia Neo L (MT25i). After updating the OS, my phone not registering to 2G (GSM only mode) network. It works perfectly with 3G (WCDMA only or WCDMA proffered mode) network. While searching for network I can see all the 2G network. I try changed my SIM, but for all the SIM its the same. While googling many are reported this issue, but couldn't find a solution. I don't know whether I am posting this on right place. Since it happened after the OS update I am posting it here. My current Android version is 4.0.4
Update
I am from INDIA and my baseband version is 8x55A-AAABQMAZM-203028G-87. Does any one have other baseband on Neo L (MT25i)?

Did you try resetting to factory defaults?

yes i tried resetting. Even i tried re-flashing using sony bridge

I think this is probably caused by updated baseband. Can you flash older baseband only?

if you don't mind can you provide me some link please...

give me few minutes

Wait... why 2G network... care to elaborate what reason is there to use 2G, when 3G is the norm?

Have you confirmed your APN settings are correct?

@Mr.Buster My issue is with GSM network, not with Internet connectivity.

@ShineethHamza did you flash via flashtool?

If yes did you notice the line this file is ignored simlock.ta while flashing

@sameer I checked the SIM lock on service menu after flashing. There is no SIM lock. all are open.

@ShineethHamza you flashed ftf or updated via pcc

@sameer I tried both.

I suggest a repair via SUS

While flashing via flashtool is the line this file is ignored simlock.ta appears as red. Also is your pc language set to english when flashing

@sameer No i haven't got the message this file is ignored simlock.ta on flash tool. System language was set to English only.

let us continue this discussion in chat

As it seems you have tried resetting to factory defaults and re-flashing same update, I believe the causes might be caused by updated baseband. I would try reflashing different original firmware. You can also flash baseband only via flashtool so maybe it might be worth trying to flash baseband from the firmware that worked. YMMV.
You can find links to download FTF (original firmware) for your device:

Build 4.1.B.0.587 - http://d-h.st/Vft
Build 4.1.B.0.626 - http://goo.gl/hAfwI

My bad luck dude.... Its not working. Getting same error  while trying to register on 2G network.

What error message are you seeing?

@Mr.Buster selected netw. (****) unavailable

Try flashing the latest ftf file from here. If you are already in .631 build try flashing the baseband alone. (Try downloading the ftf file again and flash).

@ShineethHamza Try changing Settings->Mobile network->Preferred Network->GSM only

@ShineethHamza working??

Not working dude.... still the same.. ;(

Do you know any version of baseband other than 87 for MT25i?

@ShineethHamza No I will suggest you to repair via pc companion or SUS

See the answer for how to repair http://android.stackexchange.com/a/67841/53576

still the issue remain.... looks like I have to take it to service center :(

Simple solution, just reflash radio for your device and it should work. If not contact your provider.

Chrome browser immediately crashes and I cannot get to my bookmarks
Does anyone know why I'm no longer able to access my Mobile Bookmarks on my Galaxy S3 since the last major Android update several months ago? Prior to that update I had no problems with my bookmarks. Now all I get is a "Aw Snap" error message. The bookmark page will appear for a split second then turns into Aw Snap. So aggravating! I don't think the problem is directly within Chrome because I've followed nearly all the online fix instructions others have given to no avail. I think those fixes were for those having Aw Snap issues on their desktops.
My last hope was one giving instructions to add Chrome To Mobile Extension on the desktop first but I was shocked that the Extension is not even a Google product! Needless to say I removed it immediately. I'm a baby neophyte in this tech world... All I want to do is get my Mobile Bookmarks that I've had for the 2 yrs that I've owned my beloved Galaxy S3...

The bookmarks would be synced to Google servers if the browser is signed in. Then try clearing the cache of the app. Uninstall any updates to the app to see if that's causing the issue. If it still crashes, clear the app data, but if the bookmarks aren't synced they'll be erased

How to export bookmark list from stock android(ICS) browser to pc
I have been using the stock browser which came with the phone for awhile and it has been really useful. Currently I have a large number of articles I have bookmarked that I would somehow like to get on my PC. I tried to use the "share" functionality but it allows you to share only one link at a time, and I have over 50 articles. Is there any way to export the entire list?

What phone do you have? Manufacturers tend to customize the web browser so the answer is different from one phone to another.

@DanHulme I flashed ICS on it myself, It's the stock android browser.

Using  "Bookmarks Sort and Backup"
you can copy your bookmarks from the default Android Browser to your SD Card Directory ( /mnt/sdcard/BookmarkSB/ ).   The filename will include a datetimestamp so you can easily tell which file you just created.  They  are regular bookmarks.html  formatted  Netscape bookmarks files that can be imported into any browser or viewed in any browser.
You can view the file with any File Explorer app by opening the folder  BookmarkSB  (/mnt/sdcard/BookmarkSB/) then open the file you just created with Browser or any other browser.
One way to copy the created file to your PC:
You can use an app such as "3CX Droid Desktop"
Download the file from your tablet to your PC.

Invoke 3CX Droid on tablet,
open the url in a browser on your PC   i.e.  http://192.168.0.xxx:8080
then in File Explorer within 3CX Droid viewed on your PC, open the folder on the tablet select your file,
then use 'download' on the 3CS Droid File Explorer menu  which will save your file on the downloads folder used by your browser,  the shortcut to view your downloaded files is probably "Ctrl+J" on your PC.
Open the HTML bookmarks file

FWIW  if you were to import into another Android browser that cannot sort bookmarks you would want to sort bookmarks in your default browser in reverse order before you export.  Rearranging bookmarks one bookmark  at a time would be very tedious.   This is assuming that import inserts them  one at a time at the top of your bookmarks instead of at the bottom.

Google agenda question (Still need help)
my question is more related to the Google contacts system than to Android itself, but hope you can help me.. I have a Nexus 5, and my agenda looks organized with everything that I added perfectly. The problem is when I go to the people section is shows me clones of my contacts for example: my girlfriend contact with phone number and another with the Skype name, but it's the same person. The problem is that when I try to merge both contacts to be perfect, it doesn't stay with my contact name but instead with the Skype name! For example, her name is Ana and her Skype name is Anaaa.. And when I merge them it appears now as Ana.. Not only in people but also in my contact list.. I tried to see in the settings to fix this, but can't find the solution.

That answer just fix half of the problem. It solves the clones contacts, but it doesn't solve if I want to add her Skype to my contact and keep her real name! Somehow this Google contacts seems to prioritize Skype name first and real name after.. Doesn't make sense!

You can hide all Skype contacts in Contacts to display settings.

Allwinner A13 tablet stuck on boot screen
Okay, here's the deal- I received a generic Chinese tablet from a friend in early January, and it worked well for about two-and-a-half months. Then, just recently, I discovered rooting and the wonderful things it allowed you to do, and my problem followed shortly after. I decided to download a system-tweak app, which included a CPU control. I was a little wary of overclocking my CPU, having heard it may decrease its life expectancy, but finally I thought "What the heck?" and in a brilliant stroke of genius cranked my 1Ghz processor up to 1.5Ghz, and it promptly froze, forcing me to power it down. When I turned it back on, I discovered that it had been factory reset. I re-installed my apps, including the system-tweak app, and decided not to touch the CPU controls for a while. Soon after, while at my sister's talent show, I discovered I had about 30% battery life, and I was still supposed to record her. So I figured I'd underclock it to save the battery. Unfortunately, as my finger touched the slider, my brother bumped my arm and caused me to lower the CPU frequency to its lowest setting. It became extremely sluggish, almost to the point of being unresponsive, and finally I had to shut it down. When I restarted it, it started to boot but then got stuck on the shimmering Android logo, and now that's all it does. I can't even boot into recovery mode, and unfortunately I had just turned off USB debugging that same day. I would like to know if there's any way to get it working again, and if so, how. Any help would be GREATLY appreciated!

Can't find Package and Tools buttons on the top part of the Android SDK Manager
I have Eclipse installed on Ubuntu with the Android SDK and latest JDK and JRE. I'm trying to manage add-on sites in the Android SDK Manager, but I can't find the two tabs for Packages and Tools as I normally do on my Windows PC with the same settings.
I also tried installing the ADT bndle, but still the same thing.
This is a screenshot of what I have:

This is what I'm expecting:

I'm sure I'm doing something wrong, and any help will be appreciated. Thanks!

Is the menu bar at the top of the screen, instead of inside the window? That's how Unity (the desktop environment in Ubuntu) works.

Sorry i dont quite understand you question...however i cant see the packages and tool tabs in any case

hi you are right! the question mark in your answer confused me a bit...i thought you were asking me (foolishly)..thank youuu

Watching "filmon tv" channels on my TV using chromecast and my smartphone
I know the android app called "filmon tv", it is great and with it I can watch UK and USA TV channels on my smartphone. I have also a chromecast device on my TV and wonder how could I watch these "filmon tv" channels on my tv since I do not see any option on the app.

A Chromecast version of FilmOn is now available in the Play Store - it works perfectly!

If you have a Nexus 4, 5, 7, or 10, or some "Google Play edition" phones, running KitKat, then you can simply cast the whole screen of your device. In the settings app, go to Display, then click Cast screen. This can cast to any Miracast device. This might not work with the particular app you want to use: the app can tell Android that its content is "secure", which will exclude it from being recorded or cast in this way.
One of the CWM developers has an app called Mirror. This can cast the whole screen to a Chromecast device, but it's in beta, so you have to register to download it, and it only works on the Nexus 5. See his announcement on G+ for more information and to register.
Otherwise, all you can do is contact the developer and ask them to add Chromecast support to their app. This would be the best option in any case, as the app could make sure that only the movie stream is sent to the Chromecast, rather than the whole screen (including the notification tray and navigation buttons).

Is it possible to adb connect android via wifi without configuring port on android?
I can connect via wifi by typing these codes in android terminal -
setprop service.adb.tcp.port 5555
stop adbd
start adbd

and connect ip:port on PC adb  .. it is connected
.. Is there any possibility to access without configuring on android !I mean looping port no:. Can it be possible ? kindly suggest me please !

If you have a later version of android (it works on 4.4 for sure), there is a wireless debugging option in developer tools. You can activate that and type this in terminal,
adb connect <ip address of phone>
It will default to using port 5555 if you don't give it a port. I think that's what you're after.

Thank you for answer. I want to use it for older version :(

No. What you're doing there is not just setting a port number away from the default: setting the number at all is what causes the device to start listening. Before you run the steps in the question, the device isn't listening for adb connections on any port at all.
For this reason, there's no "default port" to connect to without setting anything up on the device.

Yes, Port Defining is vital process .Thank you!

If you can build the AOSP by yourself. You can add the property to the build.prop:
service.adb.tcp.port=5555

Does this change the value of the default port that is used to connect to my device?

There are Apps on Google Play which make it possible to enable ADB Wifi with a button click. If you have root (as I can see), you won't need a PC and it does the switch in a second. An example App: ADB Wireless (root) - Google Play
I think that's what you asked for. If you dig deeper you can find apps with the option to set a custom Port. Good luck.

Phone makes sound when waving a credit card near it
I have a Samsung Galaxy S3 and the phone was in my pocket. I forgot that my credit card was also in the same pocket and just out of nowhere my phone played the notification sound, so I pulled it out of my pocket and there were no notifications; no new email or SMS, nothing.
So then I pulled the card out and swiped it near the back of my phone, and then the sound played again. I did it like 20 times and it always happens. Why does my phone play the notification sound when I wave the credit card at the back of it?

Does your credit card have an NFC chip? The phone can read and write NFC data. It is probably activating Android Beam or S Beam.

Ohh, I forgot all about NFC. I didn't think we even had that in Australia yet. @mcrumly, does thing mean that we can find something online on our phones, and buy it with our cards by waving the card near our phone?

Probably not. But you can buy things with your phone at a store that accepts NFC payments. I don't know what is available in Australia,  but in the US I can pay using Google Wallet, Isis, and a few others.

Enable usb debugging mode from adb under clockworkmode "Broken digitizer"
My friend brought me a Xtreamer Q mobile phone with broken screen, clockworkmode is working, but USB debugging mode is disabled, I found some posts about how to enable it from adb i tried them and none of them worked.
here :
https://stackoverflow.com/questions/13326806/enable-usb-debugging-through-clockworkmod-with-adb
and from this tutorial i learnt how to edit build.prop file.
http://www.modaco.com/topic/328943-quick-guide-to-modifying-buildprop-with-adb/
the commands i have used are: adb pull, adb remount, adb push.
While i was under clockworkmode i mounted system and i pulled build.prop then i added this line to it persist.service.adb.enable=1, used remount then pushed the file after that reboot, but i couldn't find the device in adb when it have booted normaly.
Next i tried to set adb_enabled to 1 in /data/data/com.android.providers.settings/databases/settings.db by following some steps from here
ttp://forum.xda-developers.com/showthread.php?t=774507
and it also didn't worked "The device was not listed".
Also i have tried this zip file from clockworkmode it didn't work too...
Install adb enabled setting from zip
My phone do not support USB org cable

can't uninstall app
My Samsung Galaxy Mega with Android 4.2.2 will not allow me to uninstall an app (Gravity Screen 1.80.8) even when I stop its running service.  When I select it from downloaded apps the Stop and Uninstall buttons are greyed out, even after waiting for over a minute. How may I remove it?

Take a look at the logcat mesages, if possible?

Download ES File Explorer and uninstall Gravity Screen by going to App Manager then select Gravity Screen and uninstall it.

Found this on YouTube:
Go to Settings -> Security -> Phone Administrators, then un-check this app and proceed to uninstall it by the usual means.

What do I do if this doesn't work?

Open the Gravity Screen application. On the lower bottom there is uninstall button. You can uninstall from there.

Eclipse AVD emulator stops at black screen with time
I've downloaded the latest Eclipse ADT bundle for linux and now I'm trying to run the "Hello world" project.
Whenever I run the application the emulator shows android splash screen and then stops at black screen showing time and a notice in the right top corner saying "Voice actions disabled in this preview. Swipe to dismiss". I've discovered that I can do following things:

Turn off the phone
Switch into airplane mode
Change the volume

I'm enclosing a screenshot of the situation.

How did you create the AVD (the system image the emulator runs)?

You mean the settings? If yes here they are: Settings

Try changing the CPU to x86. It is quite likely because you have it set to Android Wear ARM.

@ChromoZoneX ARM is the only option I have.

That's odd. I'll check that when I get home. Have you tried using another device ... like the nexus 4/5 avd?

@ChromoZoneX Changing the CPU to x86 made it work! I did some updates (downloaded everything I could in Android SDK Manager) and then x86 CPU became available. Thanks a lot!

The CPU had to be changed to x86. Then it worked.
See question comment thread for further details.

How do I uninstall the LINE app (third party app)?
At my sister's suggestion, I installed the LINE app in my Galaxy S3. After a while I decided I didn't like it, so I want to uninstall it. Weirdly, when I open Settings > Application manager, there is no option to remove application, only "Uninstall update", which restore an earlier version of the app. The same situation when I open Google Play, the "Uninstall" button only uninstall the updates and restore an earlier version. Same luck with trying an uninstaller . I also read that some application may prevent uninstallation by setting itself as Device Administrator, but I check my Device Administrators and LINE isn't listed.
I only observed this behaviour before for system apps or apps that got installed by my carrier, but LINE certainly isn't such app, I installed it myself. How could they have uninstall restriction, and how can I uninstall it?

Is your phone rooted?

Seems like 'Line' has been converted to a system app. You can convert it back to a user app and uninstall it if you have root permissions by using apps like App Uninstaller or System App Remover.
Otherwise you can disable it after uninstalling updates. "Disable" button can be found besides the "Force Stop" button under Settings → Apps → [offending app]
Else restore your phone (preferably from a Nandroid backup if you're rooted with a custom recovery). Even a factory reset might work.

Just to clear your doubt: factory reset doesn't delete a system app. If the Line app is a system app, it would not be affected by factory reset, other than any updates that it may have received after the last reset.

Have you set this application as the default SMS client, given it notification access or administrative rights? I'd suggest look into those issues as it may (although the it should not be) a factor in the issue.
If none of the above are mentioned, and you're only able to uninstall updates, try disabling, deleting set directory then uninstalling. It should remove any files that Line uses to store info.
I'd comment, but alas not enough rep.

Diagnosis: Very rarely (but it DOES) a 'placeholder' version of an app is built in a ROM and cannot be uninstalled regardless of updating. If LINE is not set as Device Administrator, then the only possibility for this case is that it's a system app.
Solution: To uninstall it, you need either root access or a custom recovery. If you have root, you can use an app like System App Remover to force remove it, or simply delete it's file from /system/app using Root Explorer. After a reboot LINE should be gone.

Unroot R-Box (Android 4.2.2 device)
I've bought an Android TV-Box from ebay - it's called R-BOX. I got the device with Android 4.2.2 and root access. However I don't want root. I tried to reset the system and remove root with SuperSU. None of it worked. The vendor software version is RK3066_R-BOX_ANDROID4.2.2-SDK_V1.0.0_130308.

Did you look in the SuperSU app settings itself... For a very long time the option to completely remove itself has been there. EDIT: Why do these old questions keep popping up in my feed list?

You could install Titanium Backup and freeze the SuperSU app which provides root access on your device. I wouldn't recommend uninstalling it if you don't know how to get it back.

I think this device does not contain neither su binary nor SuperUser
So, At the factory level, when the software team releases the firmware build for your device, they have signed it with the public AOSP test keys, thus ro.secure=0 and the adbd is probably insecure, so it will mount your device for R/W with those commands:
adb root
adb remount

Take a look at your Build number if it's ending with test-keys or release-keys
If you have a firmware with test-keys the easiest way if to find another firmware with release-keys

Yes, preloading has been removed from version 5.6 (and above).

How can I secure my pictures, videos and other files stored on my phone?
I am looking for a way to protect every sort of data that is saved in my Android phone from being stolen. I have done some research on Google Play, the only app I found with all the features is Folder Lock. Other than this app, the majority of the apps do only have a couple of specific features. Is really Folder Lock the most comprehensive app available at the moment?

What are you trying to protect them from?

From getting leaked. They can be stolen physically or through hacking

It would help to know which phone you are using, and version of Android installed on it.

I am using Huawei Ascend P6 with Android Jellybean 4.2

I would recommend using full disk encryption and keeping your bootlaoder locked and phone unrooted if you want the best possible encryption that Android natively provides.
This article explains how to do a full system encryption on Android.
http://www.howtogeek.com/141953/how-to-encrypt-your-android-phone-and-why-you-might-want-to/

Yes it is nice Thanks for the recommendation. But, still, Folder Lock for Android is appealing me more. You gotta see its specification and again give an opinion.

Google + cloud autobackup confusion
I installed the Google+ application, I then enabled "Auto Backup" , and checked "Back up local folders"
it says "uploading 173 of 600" and some of the photos in the gallery have a "cloud" icon on them (I assume this means they are uploaded to my account).
When I go to my Google+ account I can't see any photo there. I even tried searching for #AutoBackup and there are no photos. This is an hour or so after I was connected to Wi-Fi, of course.
What am I doing wrong?

Are you sure you are signed into the same account on the phone and on the PC?

And signed in on the PC at all, for that matter. Photos uploaded with G+ auto-backup are private by default.

I'm signed in at both places. When I upload a photo from the PC I can see it in the mobile app.

I even tried logging with the same account from a different device, and I see the photo uploaded from the PC there as well. But I cant see the backup photos in the second device either. What does the small icon of a cloud mean?

Is the could icon solid or just an outline? If it's solid the photos have been uploaded.

It can take some time for the photos to appear online. I think you just need to be patient.

The icon is an outline.  This means they are still uploading? @abraham

Yes. An outline means the photos are still uploading. You can actually watch the outline images fill up as an specific image gets uploaded.

I get it, not it works. I just had LOTS of photos and videos and it took time. Thanks a lot! I wish you make it an answer so I could accept it...

Why newer Android versions drain the battery faster?
I've got an Android phone whose stock Android version is 2.1. I've tried several times to install some custom ROMs (mostly Cyanogenmod-based) with Android 2.2 and 2.3.
The full charged battery lasts:

3 days with the 2.1 stock version

1.5~2 days with android 2.2
~1 day with android 2.3

...And they say that android 4 drains the battery even faster!
I'm wondering why this happens:

Is the newer software using the hardware more intensively? What pieces of hardware? What pieces of software? And why?
In general, should I expect a custom ROM to drain battery faster than a stock one (same Android version)? The ROMs I installed were supposed to be more optimized than the stock one, and have less crappy services running, but meh!
If the phone was designed for a newer Android version (say 2.3) would I get a big battery boost by switching to a former version (2.1)?

I doubt this is a software issue but moreso a hardware issue. Consider the following, Newer phones typically have:

Bigger Screens
More Antennas (Wifi N, 4G, NFC, etc.)
More sensors (This includes cameras)

Either more or more advanced of what's mentioned above. This comes at a cost, as each draws its own amperage. While it may be minuscule in an isolated system, when combined together these features present a non-negligible drain on the battery.
And, While newer batteries will perform great, over time the battery will not hold the same charge as it once did, this is not a limitation of the phone but battery technology in general. I'm specifically talking about Lithium Ion batteries right now, b/c that's the most common battery in phones today.
While there are things you can do to mitigate the problem, such as staying in airplane mode throughout the day or buying power management apps for your phone, downgrading your OS likely won't help much. If anything, it will provide old power management code, as well as no support for newer hardware.
Custom ROMs are a different story, and aren't created equal. Some may have modified code to provide better battery life, some may be performance focused and not taken battery life into account.
Some phones also have extended batteries available for them. I can't speak firsthand to their effectiveness, but I obtained one for my Dell laptop and it made a huge difference. Some people are reluctant to this approach because it changes the weight and/or profile of the phone, however one must weigh that against having it tethered to a charger all day as well.

I tried Android 2.1, 2.2 and 2.3 on the same mobile. If the hardware was different, of course I would expect that the battery life could different...

As far as I know the reason for battery drain in your phone is because you are installing cyanogen roms and not stock roms or stock based roms. Even the hardware or the chipsets of your phone is old.

The android undergone many major changes from 2.1 to current 4.4.2.
The hardware or chipsets in newer phone were designed to consume
less power than the older phones.
In the OS part newer android OS were designed to consume less power.
A stock ICS installed phone consume less battery than the stock GB
installed on the same phone. But however the battery drainage
depends on the individual who use the phone.
The custom roms based on the stock rom has more optimization than the cyanogen mod based. The cyanogen roms were mainly made to taste the newer android version in your phone as soon as the newer android version is released. These roms will have some bugs. On the other hand the custom roms based on the stock roms have greater optimization with less crapwares and few mods for better performance.
No, the above points explain this that the newer android os has better battery performance.

tl;dr:
In terms of battery performance:
Kitkat>Jellybean>ICS>Gingerbread>Froyo

Tablet stuck in boot animation
I have this tablet, MSI Primo 91 and just recently I booted into recovery mode in order to wipe the cache. On restart the tablet gets stuck in the manufacturer boot animation and refuses to boot up.
I then tried to reboot into recovery mode when the android laying on its back pops up. The recovery options won't show up.
This guy here.

The device restarted and gets stuck yet again in boot animation.
I visited the website to download the firmware. I followed the ritual described in the pdf instruction file and I couldn't  recover the tablet.

There is no solution because android hasn't support of tif format. So you need to use 3rd party software. And I think that preview that you see in gmail app is generated on server side of gmail

Android Virtual Device frozen whilst loading
I have just started developing for android after a 4 year break, I see that the Android developer site now has an integrated package with everything included, in a single zip, to streamline setting up. I have downloaded and extracted the zip file and begun going through the tutorial.
However, when creating a virtual machine, it just hangs. I have followed the suggestions in this post: I can't get any of the Android Virtual Devices started
My machine has 16GB RAM and an AMD Phenom 2 6-Core processor. I have set the RAM to 768MB for the VM and even after 15 minutes it is just frozen.
The Console shows some details of the VM I have created, but does not progress much. Any suggestions on how to get a working VM?

Have you tried using a prebuilt AVD definition like a Nexus device?

Yes, attempted Nexus 4 and 5. They did not load, then attempted building one with smaller requirements, still no luck.

Try changing the CPU to x86?

Try androidx86 http://www.android-x86.org/download, just download the iso and create a new virtual machine, you only need about 1gb of ram.

I'm fairly certain his computer is more than capable of virtualizing a device. This is a good option as well if it works for development purposes.

How can I control the order in which my mp3 files are played?
I ripped an audio book consisting of two CDs and copied the mp3 files to my android smartphone but they don't appear in the right order: they are sorted by track number, so the second title is the first chapter from CD 2 rather than the 2nd from CD 1.
I used k3b on linux for ripping, converted the files to mp3 using lame and copied them to my android smartphone via usb. The meta information has been obtained from CDDB. The file structure now looks like this:
/Music/interpret/albumTitle/cd1/01-titleA1
/Music/interpret/albumTitle/cd1/02-titleA2
/Music/interpret/albumTitle/cd1/03-titleA3

/Music/interpret/albumTitle/cd2/01-titleB1
/Music/interpret/albumTitle/cd2/02-titleB2
/Music/interpret/albumTitle/cd2/03-titleB3

Of course this is the order in which I want to hear them. When I close the usb connection and start the music app the new files are recognized correctly but the order is different: the directory is ignored for sorting and the titles are orderd by track number:
titleB1
titleA1
titleA2
titleB2
titleB3
titleA3

within groups of equal track numbers the order seems to be random.
In order to fix the order I renamed them likes this:
/Music/interpret/albumTitle/101-titleA1
/Music/interpret/albumTitle/102-titleA2
/Music/interpret/albumTitle/103-titleA3

/Music/interpret/albumTitle/201-titleB1
/Music/interpret/albumTitle/202-titleB2
/Music/interpret/albumTitle/203-titleB3

but the result is the same. Directory and filename seem to have to influence. I guess the order is defined by the track number taken from the headers of the mp3 files but how can I modify it? Do I have to rewrite the mp3 headers?

Create a playlist file with the correct sequence and open it on the device. It will then play in the order given in the file.

... and k3b offers a flag to create the playlist automatically.

LG G2 music player hooking into bluetooth?
I have a 2012 C250 that I used to hook up to my RAZR MAXX, and was able to control the music (Google Play Music) from the car.
I now have an LG G2, and I noticed in the beginning that the LG player would fire up when I hit my car's commands. If i manually start Play Music, the car will intermittently recognize it, but mostly the control functions are useless. The car will still receive the audio and phone fine however.
I have rooted my phone and frozen the LG player, but no luck. All of my music is on Google Play, so unless there is an app which can play GooglePlay music that plays nicely with my car, I'm kinda stuck.
Anybody have any ideas? Thanks

Nexus 5: Different home screen with lockscreen enabled vs disabled? Huh?
community:
I am a new Android user, and I've spent most of the weekend banging around on my Nexus 5 making it work the way I want. For the most part, I am super happy. But, I'm experiencing something weird that I can't find any documentation for, and I can't tell if it's expected behavior that I think is weird to me because I'm new to Android/Nexus 5, or if it's genuinely weird.
After I got the phone, I disabled the lockscreen. I didn't intend this to be permanent--I just did it so I could get to the home screen faster while I was installing new apps and setting up the home screen. (I think I'm using the right terminology -- "home screen" is the screen displayed after you turn on the phone, and displayed again any time you press the home button, right? Because, home button?)
After I got the home screens looking the way I want, I re-enabled the lock screen with a swipe to open. With the lock screen enabled, after I swipe and then dismiss the Google search screen, I don't get my nicely configured home screen that I spent several hours on -- I see the original home screen that came with the phone, with most of my apps not available. When I click Home, I get my "good" home screen, and I can't get the old weird one to show up again until I turn off the screen. Then, when I turn on the screen and swipe and dismiss the Google search, I'm back to weird unupdated home page.
When I turn the lock screen off entirely, the correct home screen is immediately displayed when I press the power button.
I was willing to shrug my shoulders and say "Android is weird, I'll just set up this weird post-swipe homescreen to look exactly the way I want, and then it won't matter," BUT not all of my apps are in the app list to add to this weird unconfigured home screen that shows up after I swipe away the lock screen.
So, to get to the home screen I want, I have to swipe the lock screen, dismiss the Google voice/search prompt, and then press the Home button, which shows the good home screen, and there's no access to the bad home screen until I press the power button off, then on, then swipe again.
Attached please find screen shots of:
* The first thing I see if the lock screen is disabled---this is the desired home screen
* The first screen I see if the lock screen is enabled (after I swipe away lock screen and dismiss Google prompt)
Can anyone shed some light on this for me? I really appreciate the help and I thank you in advance for assisting a newbie.
Regards,
Elissa M.

When you're on your home screen, your good one, how many times do you have to swipe left to get to the Google Now page?

It would really help if you add the screenshots you describe, and one of the "Google search screen" that shows up after the lock screen.

I have seen this same behaviour when installing a 3rd party "home screen" or sometimes called "launcher". For a long time in one android device I had basically 2 home screens, the original and the 3rd party one which was much better. I could set which is default, and still could get back to the original.  Could this be what your observing?

What is the maximum charging current supported by Samsung Galaxy S3?
As the title says: What is the maximum charging current supported by Samsung Galaxy S3 (GT-I9300)?

I found that my old s3 would not charge at all with a high current charger and I had to revert to a lower current one. Mind you, the battery was totally dead though that should not make a difference.

By using a 2A Samsung charger and USB doctor and Samsung Chargring Current Lite app, I found that the MAX current reported by both USB doctor and Samsung Charging Current Lite App is 1A(1000 mA).

https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en

There are various apps on the Play Store where you can check your current charge current and your "maximum" (not sure how accurate the calculation is)
Via USB the maximum is 460mA with an average of 460mA
Via AC the maximum is 1000mA with also an average of 1000mA

This is accurate information - the S3 has a max charge rate of between ~900mA-1A.

Wireless charging also has a maximum of 460mA wherever its USB or AC
Would I be right in saying @IAmTheSquidward that the average charging current may be affected by how old a battery is?

Yes and no.  The battery has integrated circuitry that dictates the incoming current - it will only pull what it needs.  As a battery gets older, it won't hold a charge as well, but it shouldn't need less current.

@IAmTheSquidward - If you can back that claim up, enter it as an answer, so I can accept it.

I could not get my fully depleted battery to charge over 450 at first, but once it had some charge, it was up to 1200 by end of the cycle (average) with a peak of 1800.  I then hit reset and it dropped to 540 (battery at 100%).
I can only assume the battery itself then, dependimg on its level of charge, will draw at a variable rate.

Current is drawn from the load, not pushed from the source (voltage does the pushing).
The wall charger contains only a power supply. The actual charging circuit is in the phone and it's a fairly smart one. It limits the amount of current the battery can draw regardless of the current available whether 1 amp, 2 amps or 200 amps.

Yes, that is what I am asking: What is the max supported by the charging circuit.

How to pair a symbol CS3070 bluetooth scanner with a nexus 7 (2013) tablet
The pairing code asks me to type on the device which has no keys.  Is there a work around?

You don't type.  You scan in barcodes of the numbers you need.
See step 6 of this guide for the barcodes.  These barcodes can also be found on page 1-21 of the manual.

Android emulator with snapshot option not working
I create an android device with configuration:

API Level 19 (4.4.2)
CPU : ARM(armeabi-v7a)
Emulator option :Snapshot Enable .

For the first time the device load takes approx 3 mins. After that loading the device with snapshot takes 20 sec. But I found that I cannot access the device through adb or through GUI. I think this is a bug. Any way to resolve this?
I tried loading android device earlier also with snapshot but in windows system presently my emulator is setup on a mac machine.

Have you tried restarting the adb server?

Where can I get the stock untouched ROM for HTC Desire C?
I just checked XDA Developers, and I can't find the stock ROM for HTC Desire C. Is it actually discontinued, and is my desire outdated?

But here I was asking for a link specifically for the desire C as I saw it was apparently discontinued.

I understand. If we had one "where can I find ROMs" question for every Android device ever, the site would just be like a poorly maintained Google. We'd rather have one question that's useful to everybody than a load of very narrow questions.

Sorry about that, I'm new to stackexchange and I didn't have much of an idea about how it works, but thanks for the reply and I will try and ask more appropriate questions.

In xda found this.

First download and install the zip from this thread, this will bring
you back to stock
If you want to flash over your recovery and kernel Do this after you have flashed to zip, if you do it before you cannot flash any zips at all! Follow these command carefully to flash back to stock recovery:
fastboot flash recovery recovery.img
fastboot flash boot boot.img

Thanks, I was just wondering about where the download link was, because here http://forum.xda-developers.com/showthread.php?t=2092147 said it was discontinued.

Also, do I reboot before I flash the recovery and boot?

Do I have to do anything with gapps, as well?

@thePlasm its a stock rom and gapps will be there inside the rom.

I tried to install the fastboot way and it is getting stuck and boot and now my TWRP is gone! I'm trying to install CWM but it's getting stuck at the htc screen when I'm trying to boot into recovery. Please help!

I fixed that, but I reflashed Slimbean, can I flash the zip with TWRP, also, should I wipe dalvik, cache and data?

How to calibrate magnetic sensors using Cyanogenmod?
I am using a Samsung Galaxy S4 mini with Cyanogenmod (11) and want to calibrate the compass / magnetic sensors.
With the stock rom this was possible by "dialing" *#0*#. This is however not implemented in Cyanogenmod.
How can I calibrate?

Give this a go:

Try to stay away from magnetic fields as far as you can
Open GPS Essentials and tap on compass (calibration will not work when the compass is not showing)
Put the phone on a flat surface with the display pointing up
Move the phone slowly, 5 seconds per full rotation is ok
Rotate the phone three full cycles around the axis pointing upward
Rotate the phone three full cycles around the axis pointing away from you
Rotate the phone three full cycles around the axis pointing right
The direction of rotation doesn't matter

This should fix your problem.
Credit to lepidas on XDA

I tried it and it did something (much closer to north now). Results are however still inconsistent (direction of north varies by up to 90°). It would be nice to have an app that notifies me once the calibration was succesful.

Using a android tablet embeded in my car
I want to replace mycar hifi with a tablet, I have worked out the mechanical issues with putting a 7" tablet behind the dashboard where my exisiting doubld din car ICE is, with it behind the trim i have no access to volume or power without removing it, is there a device I can get that can remote control the volume level and/or the power on/power off functionality.
The tablet will be connected to my amp for final audio output.
cheers for any suggestions (thinking of hacking a BTkeyboard to bits for button funcion unless you can recomned somit better)

For volume control you can go to Settings->Sound->Volumes->Music,video,games and other media

How about using widgets? Probably cheaper and would let you control all the functionality on the device itself, without any external hacks.
For volume control, you might be able to do with a widget similar to Volume Control Widget and for the power menu try an app like Button Savior or Shutdown Menu 2.1 (Both power menu apps require root access I believe)
EDIT:
Just realized that you might have issues waking up the device once the screen turns off. Found Wave to Unlock after a few minutes of googling. It uses the proximity sensor to unlock the device. This might do the trick.

many thanks for pointers, appreciated, using an ipad would be the easy solution, but where is the fun in that

Found this on reddit. Lots of tips! http://www.reddit.com/r/DIY/comments/2jp696/i_installed_a_nexus_7_in_my_car_it_looks_awesome/

Treat Android as USB for forensics
I have a Galaxy S3 Mini. I want to plug it into Linux and treat it like a hard drive or USB device so I can use Recoverjpeg to recover photos from it, and use dc3dd so I can take the image of the Android files. I tried to do it on Kali Linux but when I tried use the command:
fdisk -l

I can't find it. Is what I want to do possible?

Newer Android phones don't act as USB mass storage devices, so you can't use PC-based recovery software on them. Those tools (and the mass storage profile itself) require that the phone gives the PC very low-level access to the storage, which simply isn't practical any more. Here's a longer explanation of why not.

Copy files and images from samsung s3 even when its almost turned off
First of all my samsung s3 is stuck on the samsung logo splash screen so i'm thinking of doing a factory restore , that's not an issue for me but i want to copy images and videos at least from the inner memory not the sd card to my laptop or pc is there any way to do that ? i seriously do not wanna lose those pictures .

A factory reset will not wipe the sdcard partition. In most cases, you can restore some application data like that (ex: WhatsApp). This might differ for an S3 but I know this is the behavior on Nexus devices.
Another option if you have a custom bootloader is that you might be able to access the internal memory using adb shell.

Developing applications under Cyanogenmod? How compatible to vanila Android? (Nexus devices)
If I am to develop (and test) my application under Cyanongenmod (base install, without any additional changes), how confident can I be that I would see similar performance of my application on the vanilla Android version? In particular I am interested in the base/hardware performance that is not so much affected by changes to GUI, animation or depends so much on user interactions.
Is the default frequency governor on Cyanongenmod (OnDemand) is the same as default frequency governor on vanilla Android?
What other things could affect performance on Cyanogenmod versus vanilla/stock Android?
** I am using Nexus 4 and Nexus 5 devices.

The governor is dependent on the OEM's choice. For example, some choose mpdecision, others use ondemand or interactive. Still others use conservative. That being said, many of them are implemented differently (ie conservative mode on a Samsung may differ wildly from conservative on an HTC). Cyanogenmod though is just based on AOSP code so ondemand/interactive governor performance under Cyanogenmod should be comparable to the stock governors for that device (OEM's implementation).  This is assuming that the Cyanogenmod branch for said device has proper hardware acceleration and what not. As Cyanogenmod is built from AOSP code, this is not a given.
TLDR: I have had a lot of phones with Cyanogenmod. It feels snappier and is lightweight but for the heavy duty apps or games, I notice very little (if any) difference in performance.

Is possible to change an app icon on 4.1 on my S3?
I have an app that I downloaded from the Play store and it's icon is very visually unappealing and I wanted to know if there is way to replace the default icon with one from an icon pack without a launcher.  Like, can I permanently associate a new icon with the app I want to change?  How can I do it? Or will the default icon always  show up in say, the Share menu but remain different on the homescreen?   Any tips?
OS: 4.1
S3

Unicon
is an icon theming tool which requires root, but it's more consistent throughout the      device.
Icon Changer changes only the icon of the shortcut, but doesn't require root.
Use Apk Extractor to get the installed apk from the device, transfer it to a PC, modify it and then reinstall it. Does not require root.

Icon changer didn't work at all. I wonder why...? Damn, no root or a PC.  :-(

Won't APK extractor require you to sign the new APK with a new key? This would mean you have to uninstall the app and lose its data to install your modified version.

@verve The Icon Changer app is only for shortcuts on the home screen: it won't change the icon in the app drawer or any other menu.

If the icon changer that were suggested are not working, and you don't mind changing your launcher, there are some launchers that support icon changing (and also theme changing and more good stuff).
As example, you have:

Go Launcher
Nova Launcher

You can have a look at the play store, and also see what other launchers can offer you!

I forgot my tablet PIN
I'm trying to log-in to my tablet, which I haven't been on in about 2 months. I can't remember my PIN. It's not giving me a chance to log-in with my Google account, so I don't know what to do.

I really doubt you've used a correct tag here.
If it's not a samsung-galaxy-s, then please update your question. Mentioning correct tablet model might help in receiving help.
...As well as rebooting your device can.

How to unlock device when I forgot my password?

Can not unlock my Android device as have no internet connection?

Instructions:-

Download Aroma File Manager latest version
Place it in the root of your sdcard(Preferred)
Reboot into recovery

4.
    For CWM:
Mount all partitions (including sd-ext if you have it)
And flash Aroma File Manager from sdcard
For stock recovery:
In stock recovery, there is no option to mount partitions, so
Flash Aroma File Manager, Click on menu option and go to settings
Select Mount All Partitions
Now, exit from Aroma File Manager and reflash it.
Now, you will see each partition is mounted
5. Now, go to /data/system
Note : If you have sd-ext mod to increase internal storage, go to /sd-ext/system/
6. Now, If you have to remove pattern lock, long press and delete gesture.key
If you want to remove password, delete password.key
If you want to remove gesture, delete gesture.key

Exit the Aroma File Manager
Reboot

I read that Aroma does not work on stock recovery. Does it?

If you have not rooted your tablet just hard reset it.

I don't think it matters if you are rooted or not. You can do a factory restore either way.

Chess Glyphs in Logitech Revue
On my Logitech Revue, different glyphs are rendered for the chess symbols than on my computer.
Computer:

Revue:

Using Panopticlick, I've ascertained that the fonts installed on the Revue are:

AndroidClock
  AndroidClock Highlight
  AndroidClock Solid
  Clockopia
  Droid Sans
  Droid Sans Arabic
  Droid Sans Fallback
  Droid Sans Hebrew
  Droid Sans Mono
  Droid Sans Thai
  Droid Serif

However, applying these to the chess glyphs (using @font-face) on my computer gives the same glyphs as with no font selected. What font are the glyphs I'm seeing, and why doesn't it show up to Flash (Panopticlick reports that it got the list from Flash)?
If this is the wrong place to post this, I'm sorry, but there isn't a Typography Stack Exchange, and this does involve Android.

What's your question?

Whoops, fixed now.

sleep setting not saving on nexus 5
On my Nexus 5 every time I change for sleep setting to 10 minutes it's simply reverts back to one minute.
I have the latest version of Android and have tried Powering off and restarting several times.
What can I do?

OK, I'll write that up as an answer. Then accept it so that other visitors can see your problem is solved.

The sleep timeout and other screen lock settings can be restricted by a device policy. This is something that you might install to access a corporate VPN or mail server, and additionally some kinds of security apps (such as antivirus). They can force security-related settings to particular values, e.g. to make sure that your work email will be secure even if you leave your device unattended.
You can see and deactivate device administrators from the main Settings app. Look under Device administrators. Most Android devices have "Android Device Manager" in that list, so ignore that, but anything else there could be restricting your screen lock settings.

Remove Menu Button from Title Bar in KitKat
I have a Verizon LG G2, which I just updated to Android 4.4 KitKat. The G2 already has the menu button in its bottom navigation bar, but the 4.4 update, as expected, put an extra menu button in the top right corner of most apps.
I find this unnecessary, and it just takes up space and messes up my workflow. Is there any way I could remove the top menu button, either through settings or a 3rd-Party App?

Short answer is no, there is no way to remove the "Menu" overflow button from within apps in 4.4, even on phones with a hardware Menu button.  This was an intentional change by Google in KitKat to unify the interface across devices.
It's possible to remove this overflow button with some OS modifications, and many custom ROMs do offer a toggle for this.  However, it requires rooting the device, unlocking its bootloader, and installing a 3rd-party modified OS.

Can xposed framework impact system performance and battery?
I've installed Xposed framework and Sense 5 Toolbox module on my HTC One X and doubt that if it is draining my battery and causing the system to slow.
I've checked with Watchdog and Setting-Apps-Running but seems like there is no background service running. What I thought was there must be service monitoring the user actions but it wasn't.
I would be very appreciate if somebody answer the question from title and explain how xposed actually work on Android.

Xposed isn't a separate service: instead, it's a wrapper in every process, which replaces some built-in functions from the Android framework.
For this reason, it's very likely that it'll have some effect on system performance, but exactly what effect depends on the particular modules. For example, it would be possible (but unlikely) for a module to replace a built-in function that's called frequently with a different version that runs more slowly and uses more battery (and probably even gives the wrong answer at the end).

Thanks for the answer. Do you think changing the button behavior like long power button for flashlight, long back for force kill process and long home press for lock screen can impact performance and drain battery performance?

Like any program's performance, it will depend not on what the module does, but how it was written. You can make a guess by looking at the source code, but only measuring on a real device will tell you for sure.

So, no matter the mod is re-compiled into system apk or using xposed module, there is no difference if code is written well?

In general, yes. Xposed is just a way of modifying the framework APK at runtime.

I am using 14 modules and despite this I never experience lagging or battery draining. But behind this positive experience is my hard work in careful selection just quality modules which fulfill my needs. With Xposed Framework can one be happy with just stock ROM.

"Share" a phone call
I would like to "share" meta data from a phone call with any app, using Android's standard sharing feature. The idea is to create a note in e.g. Podio or Evernote after receiving or placing an important phone call.
Ideally, the shared text should include both the phone number and start time of the call.
I saw this roundabout "solution", which is to simply copy the phone number and paste it, but I would like a quicker solution.
Is there any phone call log app that lets me do this? I have tried the (Sony) stock app, Call Log+ and Call Log Monitor.

GPS not always working
I got an issue with GPS on my Sony Xperia M phone with Android 4.3, which seems to work but only intermittently. When it works the lock is acquired quickly, but sometimes it seems that sattelite searching is not even initiated.

the phone is searching for sattelites / the searching doesn't seems to be initiated (click images to enlarge)
For example, above screenshots show how it looks when the phone is searching for sattelites (left), and when the searching doesn't seems to be initiated (right; notice the missing indicators from upper-left). If in the first case the lock is acquired quickly, in the second case the lock is not acquired until the GPS indicator appears on screen (sometime after minutes of waiting).
Did anybody noticed this issue? Rebooting the phone helps, but only for a while.

Seems that I finally fixed the issue, but I wanted to wait few days to be sure.
First I tried to reflash my phone again, but without wiping my DATA partition (so I could keep my apps and settings intact). This didn't worked, so I fully flashed again my phone's firmware (I was ussing only official firmwares, from Sony) but after a day when my phone's GPS worked fine, the issue reappeared.
Finally I downloaded the same version of the firmware, but for another region (I was using a firmware made for brazilian market, now I'm using the one for Europe) and this seems to work. GPS starts everytime when requested. I'm not really sure where the issue was, but if someone else encounter this issue - maybe you could give my solution a try.

Even the best GPS doesn't lock on instantly. You can use "assisted GPS", or aGPS, to help get a rough fix quickly while you wait for the more accurate GPS to get a lock; this only works when you have internet access, since it uses your IP address to locate you. Go into your device's GPS settings (Settings -> Location access)
Also try clearing the data of the navigation app and installing other gps toolbox apps to see if it fixes the issue.

The lock is acquired pretty quickly, the issue is that the GPS doesn't seems to start at all. I found that turning it off and starting it again fixes the issue for a while. The issue happens with every application which requires GPS.

You seem to have your terminology slightly mixed-up: A-GPS uses the Internet or the cell network to download the latest GPS ephemeris data, instead of having to download it from the GPS signal itself. It's a separate thing from the IP-based geolocation you're describing.

Can dual-sim phone use one sim for voice\sms and second solely for internet access?
Is it possible with dual-SIM Android phone to use one SIM-card for voice and SMS but not internet access and second solely for internet access? I tried reading PDF manuals for such phones but it's a bit unclear.
I'm moving abroad for work and will need to keep my current work SIM to communicate with the main office but I'd also like to use a local operator to access internet because it's going to be way too expensive to continue to use internet via my work SIM abroad. And I really don't like to carry a second phone or portable router for this. Looking at HTC One Dual sim at the moment, looks good but I never used dual-SIM phones before and have no idea how those actually work. Will it be able to function the way I need it to?

Yes you can. Both sim can be used for internet and voice calls. You can also select which sim can be used for internet and which can be used for voice calls.The settings can be found under Settings-> Wireless & networks.

"Ok Google" voice action bugs - Reminder voice action gives me a Google search
Ok, so here're my issues with "Ok Google" on the Nexus 5:

When I say - "Ok Google" Remind me to call XYZ at Work, the reminder page does not pop up. It does a Google search. On the other hand, if I say "Ok Google" Remind me to charge phone when I reach home, the reminder page pops up. I have both my home and work addresses listed and I have no clue as to why this is happening.
When I say "Ok Google, Call (name)", it only dials if it's an old contact. So if I add a new contact, Google says "Please choose contact".
When I Say "Ok Google, note to self" it recognizes but it does not store as a note.

Could any of you help me with the same, please?

I tried it now, the first one does do a google search.
The second one, I go it working. Create the new contact, try to search for it my typing the name. Then if you try it will call.
The third one does work, it will create an empty note but will not save it untill you do it manually.

Controller For SGS3 Mini
I have a Samsung Galaxy S3 Mini and I would like to know if I can Play games trough a controller to make it more easier.

Android supports USB controllers (using the standard USB HID profile) and Bluetooth controllers (again, if they use the standard Bluetooth HID profile). Wireless controllers that use a special wireless receiver probably won't work with Android (but they might if the wireless receiver acts as a USB HID device).
To use a USB controller with your phone, you need a USB-on-the-go adapter so you can plug the USB cable into the USB-on-the-go socket on your phone (i.e. the same socket you use to charge it).
In addition, the game needs to be written specifically to support game controllers. The description of the game on Google Play will probably mention controller support. It might have settings for the button layout (since not all controllers use the same layout), or it might be designed for one kind of controller in particular (such as Playstation controllers and clones).
There are even some Bluetooth game controllers designed specifically to work with smartphones, such as the Moga Pro. They have the conventional button layout, and often include their own app store selling compatible apps and games.

Sony Xperia Tablet Z can't setup proxy
When I'm on my tablet, I go to my wifi network, tap and hold on it, and I get a popup menu. I hit modify network, and get a popup for the wifi.
I tap "show advanced options", and then change Proxy Settings from None -> Manual.
The moment I do this the Save button grays out, and I can't click it.
Even if I fill in the proxy hostname and port, the save button remains grayed out.
Do I need root? Sorry if this is fairly obvious, I just found nothing online.

Not necessary to have root. Do you have proxy server in your environment? How about using ip address if you have proxy server.

Sorry, I'm not that great with this stuff. can you specify what you mean by proxy server in your environment? Thanks.

proxy server is you have setup the proxy hostname. But if it's not in office. It's not usually implemented such home. And, you can setup the setting  without root access if you need to use proxy which is commonly called proxy server.

if you want to setup Wi-Fi with Xperia Tablet Z, you can refer at link

The "Save" button greys out until you enter both the host name and port number of the proxy server. As soon as you enter those, the button is back and you can save the settings.

I've tried that. Filled out host name and port number, and still grayed out button.

I think you missed the password. Fill Password, then enable proxy to manual then type the proxy hostname and then the port. The all three need to be filled for the connect button to be enabled.

Filled all three. Still grayed out. I have no idea what's going on.

I found out that the "save" button is grayed out if you use a space instead of separating bypassed address with comma. Just use a comma and type the address right after the comma (dont use space after comma!).

Nexus 7: micro usb port broken
I have a 2012 nexus 7, its a beast of a device.
But unfortunately the usb port of the device is broken.
Is there any way I can charge the batteries my beloved nexus? I have opened it up, and removed its batteries from the wire that was attached to the socket. I have an external changer as well, I could try attaching the wires which are on the batteries to the external charger, but its a bit risky.
I know i could get the usb port & headphone socket for it and replace it, but it costs 75$, if i am spending that much money on an old nexus i could go n get nexus 7 2013.
So, is there any other way I can charge the batteries of the nexus? Apart from the batteries the device works well, and I hate to see the beast of an nVidia tegra 3 go to waste like that.

This seems to be a common problem with the Nexus 7. The port loosens way too easily making it hard to charge. Often this happens if you have the charger in and you pull Nexus and it twists in the socket. We can only hope Nexus improves this in the future. There are videos on line to replace the port. Like I said, its a common problem. The replacement is fairly involved and you may want to try a professional if you don't feel comfortable with the layers involved in the tear down to get to the port.

You did not give details on "broken" in which way, but if it's about not charging,
or having a flaky connection when charging:
There seems to be a common problem with the micro-USB port speciffically in phones.
It is very simple, but not so simple to detect.
The problem is dust on the "back wall" of the connector on the phone.
If you look into it, wou will just see this "wall", with no dust.
Chances are that there is dust - like fiber collected from cloth of paper in your pocket over time, but perfectly compressed by hundreds of connecting cycles. Looks just like a perfect surface (in the limited visibility situation in the socket).
So please do not make an assumption about it and give it a try - use a needle to scratch that "wall", and see how it reacts.
Next part may be easy, surprising, and fun!
(take care of unpowering the device it you use a conducting tool)

its broken in a way that it cant be fixed unless usb port itself is replaced :)

@2am Hmm... "too broken, then"... need to look for a better place for that answer ;)

yepp. I am looking for some guy who knows ICs, some electical engineer, because there was a chip attached to the battery, which had wires going to a rather unusual port.

Ask at http://electronics.stackexchange.com/! At least if you know what you need.

Sounds like it was the battery charging control, which is part of the battery pack, where it can measure the batteries temparature. That would mean you need a new battery pack.

oh, i didnt know there was a stackexchange about electronics as well, thanks mate :)

let us continue this discussion in chat

http://www.electronicspoint.com/threads/nexus-7-battery-eliminator.264487/  These guys have eliminated the battery altogether :O

@2am Take a look here regarding charging the battery directly. And note and understand the warnings. These batteries do start to suddenly burn in an unpleasent way if mistreated - and we're probably mistreating them, as long as not all pins on the battery connector are handled. The charger is inside the battery pack mostly to have a chanche to do a "emergency shutdown" of the battery if it goes hot.   http://forum.xda-developers.com/showthread.php?t=2137652
