Calendar and contacts sync using "Server" account type
Device: Galaxy S4
Android: 4.2.2
I have been looking through the Settings  > Accounts > Add account menu and found there is an entry called "Server" that seems to allow you to sync calendar and contacts from a private server. Does anyone know how this works? I have tried pointing it at my OwnCloud server but cannot seem to get it to work.

This is an account for syncing via SyncML, a protocol used by (e.g.) funambol.
In a test, I've already managed to sync some events using syncevolution as http-server, but currently I'm not sure, wether SSL connections work as well. (I've even started a question on that topic.)

Why an SD-card saved app uses phone memory
Lately I had issues with my phone's (Samsung Galaxy Mini GT-S5570) internal memory aw well as with the SMS memory. I deleted all unwanted messages, rooted my phone and used Link2SD to move some apps as well as link other ones on my SD card.
Yesterday I installed some apps from Samsung Apps and I am facing a rather weird situation. Note that before the installation I had ~20 MB free phone memory.
All those apps are installed on the SD card(at least that's what Link2SD says). The moment I finished the installation I got the error message that

my phone's internal memory is nearly full

I used APPMGR III to see what is my free memory and I found out that I had only ~5 MB left! I was so surprised!
I decided to delete all the new apps only just to find out that after that I had only ~12MB free!
Why did that happened? I checked to see if any app cached but everything seems OK. I keep having the message about the internal memory as well as the SMS one.
How can I fix that? Where did my free memory go?

Link2SD only moves the app itself to your device's SDCard. App data still go to internal storage (/data/<package_name>). For every app you install, the Android system automatically creates this directory – and I don't know of any app that doesn't put at least a few files here.
For details, please take a look at the app2sd tag-wiki. It not only explains the different App2SD approaches taken (including Link2SD), but in "Extended Methods" also holds hints for a possible solution to your problem (S2E).

Thank you very much for your answer. Unfortunately I cannot install S2E since it requires 2.3 android and I have 2.2.1. I also tried to install Data2SD but my phone's PlayStore cannot find it let alone the terrible reviews it has received. Is there something similar to those? I searched the net but I couldn't find something...

The only other thing I've heard of is DirectoryBind – though I have no experience with it. As far as I uderstood, it could be used to have the entire /data structure moved to your SDCard. The risky thing about those kind of modifications: Never even dream of unmounting/removing your SDCard then while your device is running (for obvious reasons).

Isn't there an app that can selectively move data apps? Is there a way to do it manualy? I mean to copy and paste the /data sub folders on sdcard? The thing is when I connect my phone to my laptop I can only see the SDcard and not the phone...

Simply copy-and-paste to SDCard doesn't do any good, as the apps would still look for their data in the original place. As I said, I have no experience with this, and don't even know if DirectoryBind supports Android 2.x. So I have to leave this to others. While you're waiting, try a Google search for it.

Thank's a lot! Perhaps Mounts2SD might do the job. I'll ask a new question for that! Thank's

Why am I unable to install some apps?
I own an HTC Salsa with Android 2.3.3 (Gingerbread).
The problem is that I can't download apps like Subway Surfers, Temple Run, Candy Crush, etc. The market reports, "your device is incompatible".
Does it mean hardware requirements?
Is there any way I can upgrade my phone to play the above popular games?
Update:
Very useful information from Mr. Buster. But since there is an update on GOOGLE play now, which doesn't allow you to see the incompatible information.

Screenshots (click images for larger variants)

If you check the app in the web version of the Play Store it'll tell you, at least, if your version of Android is good enough. If it is, then the developer has decided that the hardware your device has isn't good enough.

@Luv This XDA thread maybe of interest http://forum.xda-developers.com/showthread.php?t=2392504

Application developers can set their own requirements in the play store for what must be present before a game or application will be available.
For example, it is possible to require a device has a camera, or has a screen larger than a given size, or has support for a particular version of OpenGL.
The HTC Salsa is equipped with an ARMv6 CPU (MSM7227), and has an Adreno 200 GPU, which supports OpenGL ES 1.0 and OpenGL ES 1.1.
From experience, the limitation here is most likely your ARMv6 CPU, as the vast majority of sofware nowadays is written for ARMv7 capable CPUs. Googling for the names of these games, along with "armv6" shows some hits, although I would be very cautious about running third party unofficial apps that have unspecified and unverifiable modifications.
If you do manage to get the games to run, you may find they lack OpenGL support (modern games are usually using OpenGL ES 2.0 or above), considering the fact that OpenGL 2.0 is required for programmable 3D graphics (source: http://www.khronos.org/opengles/2_X/)

Thanks for your valuable inputs. Right now i am trying to install custom rom on my mobile as Zig-Zag suggested, if that didn't work, i will surely accept your answer for the Bounty.

It could mean that your phone does not meet either software or hardware requirements, or both.  You could probably spoof the identity of your phone (so that it could be recognized as Samsung Galaxy S4 for example, instead of HTC Salsa), but you can't expect the app to work properly in this case.
So, I would suggest to get an updated / higher-end phone instead.
UPDATE 2013-10-30: If you're really looking into spoofing the model of your phone, check out Market Helper (needs root).

@Luv See my updated answer. :)

Thanks for this information. Once i get some time will try your solution. And i have already rooted my device. So its not going to take time.

Ok, i did the procedure as describe and was successful in installing candy crush. But whenever i try to open candy crush it force close. So it the problem with hardware as @Pulser suggested. I think he deserves the bounty and Answer tick.

@Luv Sure, whatever works for you. :)

Google Play lets app developers restrict which devices their apps can be installed on. Developers target specific device characteristics (screen size, keyboard configuration, software version, hardware specs, geographic location, carrier, etc) by specifying them in the app's manifest. Google Play then filters which users can install the app given their device configuration. Here's what Google has written to developers about filtering applications on Google Play:

How Filters Work on Google Play

Google Play uses the filter restrictions to determine whether to show
  your application to a user who is browsing or searching for
  applications from the Google Play app.
When determining whether to display your app, Google Play checks the
  device's hardware and software requirement, as well as it's carrier,
  location, and other characteristics. It then compares those against
  the restrictions and dependencies expressed by the application's
  manifest file and publishing details.
If the application is compatible with the device according to the
  filter rules, Google Play displays the application to the user.
  Otherwise, Google Play hides your application from search results and
  category browsing, even if a user specifically requests the app by
  clicking a deep link that points directly to the app's ID within
  Google Play.
Filtering on the Google Play web site

When users browse the Google Play web site, they can see all published
  applications. The Google Play web site compares the application
  requirements to each of the user's registered devices for
  compatibility, though, and only allows them to install the application
  if it's compatible with their device.

There could be any number of reasons, then, that your device is not allowed to download the apps you mentioned. You can gain a little more insight, however, expanding the incompatibility message to view the details. Here's what ghacks.net's Martin Brinkmann has written on the topic:

Google displays compatibility information right underneath's the
  install button on that page. If your device is not compatible, you
  will receive the following information:

Incompatible does not necessarily mean that your device's technical
  capabilities are incompatible with the app. While that may often be
  the case, it can also refer to geo-restrictions that the creator of
  the app has set. Apps can be released only to select countries, and if
  you happen to live in a country that the app is not (yet) released in,
  you too will receive the incompatibility message.
Now, to find out why your device has been deemed incompatible click on
  the small plus icon in the bottom right corner of the message.

Here you find the reason why you cannot install the app to your
  device.

As a last resort, consider contacting the app developers to ask for a better understanding of what makes your device incompatible.

Thanks for this very useful information. You are at top for bounty reward.

please have a look to updated Question

@Luv: Good update, it's disappointing that the incompatibility messages are so much less clear now. You might have to just investigate each app individually to see why you're disallowed. As for Candy Crush Saga, per the app's FAQ it requires a ARMv7 processor. Pulser's answer is correct, then, as your phone has a ARMv6 processor. This is likely the restriction you're running into with the other apps as well.

It could be for many reasons. Probably since the Salsa is relatively low end hardware wise and 2.3.3 is slowly becoming less supported.
I'd contact the developers and if it's an issue with the firmware, root your phone and install Android 4.0 +

It doesn't look like it's an issue with firmware. I checked the three apps mentioned and they all claim to run on Gingerbread.

@akkatracker i have rooted my phone. But can' t find a link to Android 4.0 +. Can u help me?

you could try side loading the app. just download the .apk to your phone or transfer it from your comouter and install. no guarantee it will run but it will let you install the apk.

That would require a source to download the .apk from. Preferably a safe and legitimate source. You can't download apps from Google Play "just so".

you could try the amazon store and I know there is an extension for Firefox or chrome that allows you to download apks from the play store

@Nade i tried but it Force Close

You may have luck using a 3rd party Play download service like http://apps.evozi.com/apk-downloader/ I'm not sure how shady this service is however, use at your own risk.

@ce4 , the apk downloader fetch the apk file directly from google server, so no worry. you can always double check the md5. Ask someone who able to download the apps from play store and extract/export the apk out and compare the md5 from the apk downloader (or any others method you can think of).

You should upgrade your phone. subway surfers and all these games you mentioned need higher GPU than salsa. and as someone said you could spoof your phone. The app doesnt work as expected and may slow down your phone.

HTC Salsa hardware is not that poor!
I have nearly similar config phone but i can play all of those games
the only big deference is my phone has android 4.
i suggest upgrade your rom to android 4.
i searched a little and find out it have new Roms from 2.3.3 to 4.1.2 JB.

Can you help me in how to gain S-OFF in HTC Salsa as i think to update ROM i need to gain S-OFF.

S-OFF is for rooting your phone! do you want to upgrade your android version or just root your phone?

I did root my Phone successfully. Can you give me a link for HTC Salsa Flash Roms 4.1.2 JB ?

Installing Android 4.1 or higher on Sony Tipo with permanently locked bootloader
My operator (Telecom HU) has disabled unlocking the bootloader of my Sony Tipo. I would like to get Android 4.1 or higher on my device, but so far this seems impossible. I successfully installed ParadoxRom, but I found out that it is just a re-skin of the same android version I had before. My choice would be installing Cyanogenmod 10, but every tutorial I've seen so far relies on unlocking the bootloader, and as I found out from the service menu, this is impossible in my case.

If this doesn't prevent me from upgrading to 4.1 or higher, I would like to know what rom(s) can I use that are actually a newer operating system rather than a heavily edited ICS.

Have you tried FlashTool?
This is a particular software suite for flashing ROMs on Sony handsets, however, I am not 100% confident if it supports the Tipo.
The full forum thread that discusses about this tool can be found at XDA so it might be worth a try to read the thread from beginning to end, to see if others have used it successfully on the Tipo.
If no luck, try posting a question there on that XDA thread, identical to the above question that is asked and wait for a while for someone to answer - you do need to be patient, as people are answering in their own personal free time.
Be warned though, using this tool, you could lose data, as a result of unlocking the boot-loader, there is a FTF (Flash Tool Firmware) file available for listed and detected devices, which can circumvent this and also can re-instate the boot-loader lock mechanism.

I've not used FlashTool before, and I don't quite understand how it's supposed to unlock the bootloader.

As I have stated in the answer, Flashtool is specifically to Sony handsets, those FTF files were floating around and put together as a compilation to aid in unlocking device by clicking on a blue icon representing a thunder or a spark to unlock. That is to the best of my knowledge, I have used it on Xperia Mini, unlocked bootloader, discovered upgrade to ICS was impossible because of bootloader state, had to lock it, then ICS upgrade happened, after that, I had to unlock it again to put LegacyXperia ROM on it and have not looked back since.

They key problem here is that I cannot unlock my bootloader and thus I'm unable to flash any sort of advanced firmware. You keep telling me I need some "FTF" files, but you never pointed me towards any directly, and I still have no idea if I will be able to unlock the bootloader or not.

All the FTF are contained in the FlashTool distribution which weighs in over 100Mb in size.

How do I setup a Gmail account with 2-step verification in K-9 Mail?
I'm trying to setup my Gmail account in K-9 Mail, but when I'm setting up the incoming server, I keep getting the error: "Wrong username or password". When I'm trying to set up an outgoing server, I get an error which directs me to the two-step verification at Google.
I have 2-step verification configured on my Google account, but can't seem to get this into K-9 Mail. I've searched all over and tried following different guides, e.g. this question, and I've also tried to change the password on my Google account but nothing helped.
How can I properly configure K-9 Mail for my Gmail account with 2-step verification?

IMAP clients generally need to use application-specific passwords in order to access accounts that use 2-step verification. You'll need to generate a new app-specific password, then use that to set up your incoming/outgoing servers instead of using your regular account password. Google's support page (linked above) includes instructions for doing this. Summarized, the procedure is:

How to generate an application-specific password

Visit your Google Account settings page.
On the left, click Security.
Under the "Signing in to Google" topic, click App Passwords.
Using the dropdown menus within under the App Passwords section,  select which application you would like to generate a
password for along with the device then click "GENERATE". You'll then
see the application-specific password (ASP) you just created along
with instructions on how to use it.
When you sign in to an application requiring an ASP, enter your ASP in the password field, and make sure you check the "Remember password"
option if you want the application to remember the code.

Thanks, it was becoming a mystery.  Unfortunately, it seems that you may only have the application specific password when you are using 2xFactor-authentication.  That prevents two people sharing the same mail folders.  Still looking for how to access that emai login.

I had a hard time to resolve the same problem because my Gmail accound wasn't correctly configured with 2-step verification. In case it might help somebody, here is how to do that :

Turn on 2-Step Verification

Go to the 2-Step Verification page. You might have to sign in to your Google Account.
Select Get started.
Follow the step-by-step setup process.

You will be sent an SMS with a code, and you have to enter the code you just received by SMS.

How to install Cyanogen without losing data
I've been using ICS on my Samsung Galaxy S3 for a while now, but I can't update to Jelly Bean for multiple reasons.
I've decided to switch to Cyanogen Mod, is there any way I can move to Cyanogen without losing any application data?

As geff described, you cannot avoid a wipe/factory-reset. But you can do a proper backup beforehand, so you can restore most of your data afterwards. This should work without any trouble for the apps you've installed yourself ("user apps"), while special care must be taken for pre-installed apps ("system apps"): As data structures (inside their databases) might have changed, a simple restore (replacing the databases) might break things and even render those apps unusable.
Provided your device is rooted, Titanium Backup is a good choice. Backup all "user apps" and their data, plus the "system apps" and their data. Special care on restore: "user apps" can be restored 1:1. Before goint to the "system apps", make sure to turn on TB's "migration" mode. Then restore only data, and do so one-by-one, after each "data set" verifying there are no side-effects.
An alternative to be named is Helium Backup, which even works on non-rooted devices.
Safest is to stick to your "user apps", and let contacts etc. solve via sync. For several things like SMS, there are special backup/restore solutions which you could use.

Moving from stock ROM to custom ROM usually requires a wipe or a factory reset. Otherwise, you will encounter force closes (FCs), heat issues, and possibly other problems. In short, headaches.
Even upgrading from a CyanogenMod (CM) to a major CM version will require a wipe, especially if it contains a major Android update. This is because the files / directories are now different (layout-wise, etc). I'm sure there are other reasons too.
Most, if not all, will also recommend you to do a wipe. This is the best way to ensure that the installation will be smooth.
Of course, you can still rely on Google Sync to ensure that your contacts (and other syncable data) can be restored.

Resurrecting an old thread.. but see http://forum.cyanogenmod.org/topic/74526-how-do-i-update-cyanogenmod/ which says you don't need to do factory reset/wipe cache etc....

That's discussion related to updating from one version of CM to another. In that case you're right, you generally don't need to do a factory reset. That's not what this question is asking about, however. When installing CM for the first time, it is still recommended (and typically required) to perform a factory reset in order to prevent the device from getting stuck in a boot loop.

Need help. I'm going to install Android 4.1 on at&t HTC One X
I've just started upgrading of my HTC One X at&t version.
Jelly Bean (Android 4.1) released for AT&T HTC One X .... but how to install it on unlocked AT&T phone?
I followed this link.
There are instructions how to update it in the answer in this link.
When i entered into recovery mode, TWRP manager menu appears.
on the step 4:
-"Now, press and hold both the Volume Up and down key and then while holding them, press and release the power button. After releasing the Volume rocker key, you will get a Blue Menu along with a set of options which will indicate that the device has been successfully landed in the Recovery Mode."
but this combination of buttons just lock screen, and there is only Swipe To Unlock button.
Can anyone help me? what should i do in this case?
Thanks in advance :-)

The description points to booting into the recovery mode, so you must do that while the device is switched off (not while it's running).

Cannot install google play services
My HTC Desire S (Rooted and installed with Sabsa Prime ROM) have Avast Mobile Security as antivirus. Recently I was given a free Premium Security code by Avast. But I'm unable to update the code on to Avast as the following error message is shown.
"Google Play Services, which some of your applications rely on,is not supported by your device. Kindly contact the manufacturer for assistance".
I have tried installing the Play Services via Google Play Store as well as manual apk installation, but still it doesn't work. Manual apk installation did say the installation success, but even after rebooting, the Avast says the same error message. HTC Desire S does support Play services, as said by Google Support page. Please help!!

Have you tried installing the gApps specific to your ROM. I have no experience with Sabsa Prime but this helped with CM

Yes I did. But it didn't work..

Samsung Galaxy S2 factory-reset lead to boot-loop
I have a Samsung Galaxy S2. I factory-reset my phone from the Settings option, but it is taking too much time. It has been 24 hours already, but the device is only boot-looping. I've also tried to boot into recovery-mode (by holding the Vol+ and Vol- buttons while pressing Power), but this boot-looped as well.
How can I solve this problem? The device is rooted, if that's any help.

Comments are not for extended discussion; this conversation has been moved to chat.

Get a USB jig, that will get you into download mode. It's just a 300k Ohm resistor that bridges a couple of pins on the USB port.

I have Samsung phones that have this bug in which you go to boot-loop in almost every reboot session. I also faced this, so I luckily have a solution and see if it works.
Just turn off the phone completely, remove the battery, wait for a minute or two, put the battery back in, and start the phone. This started my phone correctly as it was previously stuck on the black bootloader screen and wasn't even going to the boot animation stage.

How can I change SELinux from Enforcing to Permissive on Samsung Galaxy Note 3?
My device is Samsung Galaxy Note 3 SM-N9005.
This phone comes with SELinux set to Enforcing by default.
I have been trying to change this to permissive but to no avail.
I built the kernel from source code following Samsung instructions, and added a line to init.rc file in the ramdisk: "setenforce 0" and this worked, however WiFi broke and I am not clued up on kernel development.
I have tried, as root, running "setenforce 0" in terminal and via adb. There is no error, however it stays Enforcing.
I am running out of options have looked through the init files in the Samsung source code and cannot find anywhere where Samsung set SELinux to be Enforcing.
Any help will be vastly appreciated!

I tried "su setenforce 0" in terminal which worked temporarily but init.rc file seems like renewing on every boot and "setenforce 0" command is not gonna be permanently. However I'm using i9505 MI8 android 4.3 CF-Rooted and setenforce command works in terminal which means SElinux is not locked on my device. I hope Note3 would be the same

setenforce changes only the runtime mode, so if you want the change to persist over reboots, add setenforce 0 to your init.rc files or edit the value of ro.boot.selinux

I'm not sure how this answers the question.

You cannot get root shell from ADB on stock and Enforced devices since 4.2.2, without additional boot.img hacking. This make a terrible mess for everyone, but you can do it from a local terminal shell.

If you're rooted, install Android Terminal Emulator from Play Store and open a root shell. Also make sure you use latest (>2.00) SuperSU to handle SELinux. Then type: su 0 setenforce 0 and see what happens. Check with id. If that doesn't work, also try with: su system setenforce 0. In AOS >4.3, it's not enough to just be "root" (uid=0), you also have to use the right context.
EDIT: 2015-11-06
Apparently, since AOS >4.4, Google started using a permanent enforcing mode which actually enforces the SELinux policy. These phones have disabled the Permissive option through the DCONFIG_ALWAYS_ENFORCE=true kernel config flag in their Kernels. You need to flash an insecure Kernel (e.g. CF_Root) or a brand new kernel where this flag has been disabled.
Google writes here:

In the Android 5.0 (L) release, Android moves to full enforcement of SELinux. This builds upon the permissive release of 4.3 and the partial enforcement of 4.4. In short, Android is shifting from enforcement on a limited set of crucial domains (installd, netd, vold and zygote) to everything (more than 60 domains). This means manufacturers will have to better understand and scale their SELinux implementations to provide compatible devices. Understand that:

Everything is in enforcing mode in the 5.0 release
No processes other than init should run in the init domain
Any generic denial (for a block_device, socket_device, default_service, etc.) indicates that device needs a special domain

For more info how to recompile your Kernel, look here.

doesn't work on my S5, still enforcing :-/

Root Android x86 VirtualBox
I have installed Android-x86, version 4.3 Jellybean iso image into virtual box, and want to run some applications that require root privileges.
Is there any way to root it?

I'm just sitting in the same boat. There's a guide + script on How to root Android x86 4.3 at XDA, but it didn't work out for me (apparently neither for some others on the thread), while there are positive reports as well. You might be lucky with it. If so, it would be interesting to know what image you're using, and where to obtain it, in order to cross-check (it might be differences in builds).

Google Hangouts keeps history regardless of settings
I use Hangouts to chat with friends. As I don't want to keep history, I set it to be turned off.
So whenever I chat, in the input line I see a constant message of "History is turned off".
However, when I open Hangouts again, I can see messages that were sent days ago.
A simple question: how can I see older messages with history disabled?

The history setting only affects messages as they are sent. Turning history off doesn't delete old messages that were sent while history was turned on. If you want to delete your old messages as well as stopping new messages being saved, you can do this with Delete in the chat's menu (or Delete history in the web-based client).

No, I deleted all the messages a long time ago and turned off history and now I can see the messages that I sent this afternoon. I need them gone without any interaction.

Go to settings, apps and touch the app, and click clear data. Now check if you are able to change the settings and the the settings works.

Open the person hangout. You can uncheck conversation history and you can delete conversation.

Move app data to SD
I would like to move some of my app's data to the SD card. I am running Android 2.2.1 so I cannot use Simple2Ext.
I would also like to avoid Data2SD because I've read some bad reviews let alone when I search it on PlayStore the responce is tha the application cannot be found.
I have also tried Link2SD and AppMgr III but those apps don't actualy remove data, as I have read in the app2sd tag-wiki
What can I do to move selectively my app's dat?

You can try:

AppMgr III (App 2 SD) - Android 2/3/4
Link2SD - Android 1.6+

Thank you very much for your answer! I have already tried those two apps, but they can't remove data;they move just the apk, as I have read at the app2sd tag-wiki.

if you want to remove data of an app: go to settings, apps (or app manager), tap on the app, scroll down, press "remove data"

That's a good answer, but I think the OP wants to move the app's data directory to the SD card, rather than just clearing the existing data.

Yeah, there's a tiny little difference between "re: moving data" and "removing data" :)

Samsung Galaxy: Unlock gone haywire
I applied the procedure to unlock a Samsung Galaxy S3 on a Samsung Galaxy Express I437.  It went through smoothly, and but the phone was not unlocked.  Instead, it gives me the error message "Phone not allowed MM#6" after I inserted a foreign SIM card.  The procedure is reproduced below:
[1] UMTS
[1] Debug Screen
[8] Phone Control
[6] Network Lock
Options [3]Perso SHA256 OFF
(after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in
[6] Network Lock then choose
[4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone
Since this didn't work, I tried reverting NW LOCK back to the old setting.  Unfortunately, it doesn't work.  The unlock screen doesn't come up anymore.  And I have no other way to enter an unlock code.  Does anyone have any idea how to resolve this issue?
Million thanks!

Turns out the procedure worked.  The IMEI is blacklisted by the foreign network at the time of the test.

Do you need a special charger for a Nexus 7?
Do you need a special charger for a Nexus 7? I've been trying to use the same charger as I use for my Android phone and it works poorly. If you tilt the tablet upwards it's charging, but otherwise it's not. What's the deal with these Android tablets?

Note that a Nexus 7 ships with a 2 amp charger block, whereas most phones ship with .5 - 1.0 amp block. This means that using your phones charger will probably take twice as long (or longer). it should not short out or lose contact as you describe though. I'd get a new cable and try it on a PC or with your existing block.

If you need to tilt it, it's definitely a connectivity problem. The reason is most probably on the charger's end because the micro usb standard deliberately reinforced the socket. E.g, the spring was moved from the socket to the plug so that plugs break first (instead of the device's socket as with normal / mini USB connectors before)

No, you don't need anything unique. While it comes with something specific - it can charge off a USB in your computer (or the wall outlet -> USB). (Source: I have the 2012 one)
Sounds like you have other issues such as:

Bad/Obstructed USB header - Visually check the USB on your Nexus for physical damage or blocks (dust, debris, lint, etc)
Bad USB cable - Try an alternative cable or verify that cable in other devices if possible.
There are complaints of the 2013 Nexus 7, mostly related to odd behaviors with touch. Perhaps this could be another manifestation... Though I somewhat doubt it.

If you clarify further, that may help your cause: Did it ever work normally - if so, has anything changed between then and now (rooting, custom ROM, etc)? What came in the box with it? What did the manual tell you? What else have you tried? What do you mean "What's the deal with these android tablets?" - have you found other evidence of issues or reported complaints?

Where is android syncing my photo's to?
I just got an android and have it synced to my google account, the problem is that it is syncing my photo's to I don't know where on my google account, which is very bad because I take pictures of sensitive documents for my job. Every once in a while I get a notice that these synced photos are ready to share. I've looked in drive and don't see them, I've looked on plus and only see the ones I've said it's ok to share, but it's syncing them somewhere online which in the case of these particular articles is illegal no mater how "Secure" this may be.  So where the heck are these going?

What version of android are you running and on what phone?

Ice cream sandwhich, LG l9

Also, what is the exact message in your notification? For example, my Galaxy Note 2 says "Google+ Auto-backup, x photos ready to share".

Your Android phone may sync photos on Google +, Dropbox, Google Drive and Facebook.
 On Google + got to https://plus.google.com/photos/search/%23AutoBackup (Photos> AutoBackup), here are photos whose automatically synced through your android phone. How to Enable/ Disable auto sync on Android
Next is Dropbox, check this article for dropbox sync enabled www.dropbox.com/help/82/en
Next is Google Drive which may auto sync your photos & data to server.
& Facebook is also sync photos in private folder in your albums folder.
But in my opinion your photos are being synced by Google + in Auto Backup section.

Caller cannot be heard
When the my Nexus 4 is called, the telephone caller can only be heard when loudspeaker is switched on or with earphones - is this normal? - is this a case for warranty send-back?

No, it's not normal. The following might seem obvious if you're familiar with Android, but it's worth a check.
Android has separate volume levels for media (such as music), notifications, and in-call. It also has a separate volume level for when you're using headphones, to avoid deafening yourself by plugging in headphones when the volume is high. It could be that the "in-call without headphones" volume is very low, and the other volumes are normal. Try turning up the volume (with the physical volume keys) while you're in a call (with no headphones plugged in), and see if that solves the problem.
If not, it sounds like a hardware problem with the speaker that goes next to your ear. There is a separate speaker for when it's on speakerphone, or for music or videos. In that case, a warranty claim would be the appropriate course of action, especially if this is a new phone and it has always had this problem.

Thank you very much. All volumes are on max. Resetting to factor settings didn't change anything. I'll send the phone back

Gmail 4.6 Does not allow "From"/Sender address to be changed to a different email address
I did see this question, but it was from two years ago, so I know it does not apply to my question.
Before the 10/1/2013 update, I was able to easily switch my sender email account to a different email address, but now, I can't.  I have checked the settings in the app and for the email account.
Is there a setting somewhere in 4.6 that I am missing or did Google kill this feature for the mobile version?
If my question isn't clear, I apologize, and please let me know how I can improve it.
I'm using: Nexus 4, Android 4.3
After further investigation, it may be broken: gmail forum post
Thanks.

No repro here. In the compose window, if I tap my email address I get all of the "Send mail as" options I have for that account, as well as the email address for the other account I have on the device. (Gmail 4.6 on a Galaxy Nexus with Android 4.2.2.)

That is not happening for me when I compose emails emails.  I thought it may have been limited to replies, but I can't do change it.  I have a Galaxy Nexus at home, so I will update the app there and try it when I get home.  Thanks.

Have you made sure you have all the accounts set up on the device and syncing Gmail? Have you tried clearing the data/cache of the Gmail app?

I just cleared the cache.  AND IT WORKS! :)  Forgot about that until I was poking around the app settings.  I was this close to rolling back the update.  Thanks @AlEverett.

Please don't put the solution in your question. Make it an answer and "accept" it so it can act as a signpost for future readers.

Or, perhaps, this should be a duplicate of App X isn't working correctly. How can I fix it?

Where are my manners? :)  I've answered my question.

My send from menu works, but it's ignored when I click send. Email goes out as my default account.

SOLUTION: Clear the app cache.  After I cleared the app cache, the "send as" was functioning as it did before the update.
Does this fall under as a duplicate of: App X Isn't working correctly.  How can I fix it?

Not necessarily a duplicate, but it's good to know clearing the cache helped. :)

Clearing cache and app data didn't work for me.

Which app is issuing a "Synchronization successful" popup?
Every now and then I get a "Synchronization successful" box overlaid on top of whatever app I'm running at the moment, including fullscreen apps such as games or Netflix. (So to clarify, it's not a drop-down notification).
I do have a quite a lot of apps, and some of these do some kind of frequent "synchronization" (e.g. UberSync for Facebook, Sms Backup+, etc.). I've gone through their options several times and I couldn't find any obvious option.
So my questions are:

is anyone else getting this? is the culprit well known?
is there some way to figure out which app is issuing this overlay, short of selectively disabling them until it disappears?

I'm running Android 4.3 on a Nexus 4 phone but I've had this problem on 4.2 as well.

Well, the question by nature is very broad. This app could be from any app; may be from something you never expect. Can you [edit] the question and add a screenshot please?

I'll see if I can do it. It's a bit unpredictable and it doesn't last long, so it's not that straightforward.

That should be a specific API call. Perhaps you can try to connect the phone to your pc and read the logs?

Wired xbox controller not working with LG G2
My boyfriend purchased a USB OTG cable so he can play Android games with an Xbox 360 wired controller.  When he plugs the Xbox controller into his LG G2 nothing happens, I plugged it into my Samsung Galaxy S4 and it worked  immediately. His LG G2 recognizes a flash drive, keyboard and mouse right away so we know the cable is working just fine. What could be causing the Xbox controller to not work?
The AT&T LG G2 is rooted running 4.2.2 with stock ROM.  The Keylayout file vendor_045e_product.028e.kl used for the Xbox 360 wired controller was already on the phone.  Running the app titled "USB Device Info" with the Xbox 360 wired controller plugged in shows the controllers info in both the Android and Linux tabs.  The device seems to recognize everything it's supposed to but won't work with any games or emulators.  It wont even allow the controller to navigate the home screen.

I seem to be having the same problem with my Galaxy s3 rooted stock rom. It appears to me that the system doesn't load the driver for the Xbox controller to recognize it when plugged in. However, the app bt/usb joystick center is able to recognize and read inputs from the device. I don't know how to get the system to read those inputs however. My motive for posting this is to see if anyone has found a solution perhaps using the terminal emulator app to manually load the driver... I don't understand enough about system drivers to try this myself. Another thought I've had is if my device has the

(continuing FPSHero's comment) ...wrong key layout file is it different for each device? I have prod_0291.kl(possibly for nexus 7?) prod_0791.kcm(wireless) and apparently prod_028e.kl and I have edited their permissions to read, as is with the other keylayout files, but the system just doesn't call the file when the device is plugged in. Interestingly it recognizes keyboards usb drives etc without root access or editing system files etc.

While I do not have the final solution - I was able to make some progress in figuring out why the G2 fails to work with the 360 controller.
I've been doing diagnostics and noticed that the LG G2 USB connection manager is emulating a USB2.0 and USB3.0 device hub - which shows up when an OTG cable is connected to the phone - and while it identifies the 360 controller, its non-standard integration is likely causing the device to not be recognized by applications.
Using USB/BT Joystick Center from the play store, I was able to refuse permission to access the USB Hub devices, but permit the app to talk to the Xbox controller. (When it scans for devices, it will display "FOUND: Device Name" then prompt for permission. When it displays "FOUND: Xbox 360 Controller" approve access. Deny all other prompts, or else the software cannot communicate with the controller).
Immediately after doing the above, the controller's LEDs stopped flashing - and locked into 'Player 1' configuration. Then the software loaded a default 360 profile, and clicking on driver let me see the raw inputs from the controller. It works!
It seems to me that the device is perfectly compatible, but the LG OTG input manager is doing something funky with the input - and needs another piece of software to channel the inputs from the USB device to the system. If there were a way to get the LG software to identify it as a keyboard or gamepad, that would be ideal.
I'll keep working at it for now.

Is it possible to recover deleted text messages after a factory reset on LG Optimus One 2.2.1?
I have never backed up anything off my phone. The text messages I need are from within the last month. The factory reset was done a week ago..

Alas, the SMS are all gone, they're part of the data that gets wiped along with the factory reset.
There's no way to get them back (if you haven't backed them up at some time)

Follow the steps below to recover the deleted SMS from android phone. Have a try.

Connect your Android phone and enable USB debugging
Analyze your Android phone
After the USB debugging, reconnect your phone if you are asked to disconnect it during the setting.Here you need to bear in mind that your phone's battery is more than 20% charged, and then you can click "Start" to let the program analyze your Android phone.
Scan your Android for deleted text messages
Preview and recover messages from Android
Good luck!

Battery charging indicator went crazy on my Samsung Duos S6802
While I was playing a game, my cellphone warned me that my battery went too low. I plugged the charger but it was like it didn't work (charger indicator didn't show the bolt icon). After several efforts I found out that the battery was charging, simply the indicator didn't work. Unfortunately on my panic I had done a format (USB Storage) thinking that an installed app was causing this. However, this was not the case.
The battery charge indicator is now working half the times I am plugging it for charging. Upon going to the battery statistics, I observe a strange behavior: it shows it is almost (or half) -empty but the battery timer says that there is enough battery for 3 days while in another phone with similar battery and phone usage it shows full battery but 11h remaining time only.
How should I proceed?
Samsung S6802 - v.2.3.6 Gingerbread

The game's creators did not take right precautions for the version of android I have and it ran into some issues. Unfortunately, it is not recoverable with format; the problem isn't obvious at first sight though.

whats the use of my places in android 4.3?
I noticed there is my places under location services. It saves the office home and car location by a format I specify (wwfi bluetooth or map).
 How is this used in android? Am I able to find my car location for example?

According to Google Support:

My Places gives you easy access to your important locations and
  personal Maps history. Whether you’ve starred or searched on your
  phone or computer, in My Places you’ll find your:

Offline Maps
Starred places (including Home and Work locations)
Recently viewed Maps items
Directions
Search queries
My Maps
Rated Places
Maps searches

That's the help for the Google Maps app, not the Android "My places" in the location services.

Is there an Android equivalent for iPhone's "mobileconfig"?
iPhone provides an easy way to add Email accounts using .mobileconfig files, "installable configuration profiles" or whatever they call it. Its basically a XML file containing all the parameters needed to install the Email account, its extremely handy.
But I'm in need of something similar for Android. Any ideas?
Or perhaps something I can configure in my server that makes Android detect the technical stuff automatically, like the IMAP and SMTP server/port etc. Google is not being helpful on this.

Nope, unfortunately there is nothing like this to my knowledge.I'd love to be proven wrong though

How to make incoming SIP calls work on Android 4.x?
I have a SIP account which I entered into the "Internet Call Settings" of the native android phone app. I am able to place outgoing SIP calls, but no luck with the incoming ones. I am new to the SIP subject, so I was wondering what I am missing and a description how incoming SIP works would be a plus!
Info:

Phone: Nexus 4
OS: Android 4.3
SIP Provider: didlogic (sip.didlogic.net)
Google voice account: available

Feel free to ask for more info. I want to figure this thing out.
EDIT: I am on t-mobile $30 unlimited data and text plan, in case it makes any difference, but it still does not work when im at home on wi-fi.
EDIT 2: Let me ask this: How does the inbound SIP work? Does the phone or wi-fy needs to constantly listen for a signal at the port 5060 or is the phone does a simple alike keep-alive connection with the SIP server in the background?

possible duplicate of Android phones with native SIP client?

Not a duplicate to that one. OP writes he already set up an account successfully and can make outgoing calls, just not receive inbound calls, so this is different.

Yeah, I did not really need the setup instructions and I do have the "receive incoming calls" option turned on.

On Android 4.1.x with enabled native SIP call stack:
Internet Call Settings > Enable Incoming Calls
If you set your DID account correctly and your SIP provider supports DID, then you will be able to receieve calls.

I do have the option to receive internet calls turned on. What does correct DID acount setup intails?

You need a VOIP Provider that allows you to have a Direct Inward Calling number. You need to buy a DID phone number or enable that service in your VOIP provider. I don't know how to setup a DID Number which you've bought form another provider thatn your VOIP provider. But if you use a provider, that offers both, then you can be sure the inward calling works if you enable it in the settings. example: voip-club.biz

Install the app Sipdroid and setup/use with Google Voice. This is the way I use SIP and it works perfectly.

How to get my lost Xperia SL back even after factory reset?
I'm new to this forum, I have lost my Xperia SL yesterday in a bus. I have registered police complaint with my IMEI number. I was trying to locate the phone using android device manager when someone uses my phone's internet. so far nothing is going correct.
When i log in to the google play with my email-id, my mobile phone model has been showing.
I have a doubt that, when the thief does a factory reset, and sign in using a new account in google play, will i able to still detect my phone with its registered model number?
will i able to track my mobile with any of the technology? (I have not installed any tracking apps in my mobile).
or i have to wait for the police to track it with my imei number?
Can anyone help me to clear my doubts?
I have not changed my password of my gmail, so that i may have the more possibilites of tracking my device.

As soon as the device gets factory-reset, you can forget about tracking it with Google's Device Manager: As your Google Account on the device is gone then, there's no way for Google's DM to communicate with it.

So the only way i can track it once my phone is factory reset is with the help of the police with my imei number!!!!

Yes. Unless you've installed some anti-theft solution which integrates with the ROM (and thus survices a factory-reset). But even that would be gone as soon as a new ROM is flashed. As long as it's still working, you could take a second device and follow the lost one. Once in range that you should be able to see it, you could trigger the 5-minutes-permanent-ringer. In the hope for an "honest finder", who should take this as a proof and hand your device back to you. Don't wait too long, or the battery might be dead.

@Izzy Why is this a comment and not an answer?

Good point. Summed up everything and made it an answer. Thanks for the heads-up!

Unless you've installed some anti-theft solution which integrates with the ROM (and thus survices a factory-reset – a feature offered e.g. by Cerberus, if your device is rooted), you will have lost all control then. But even a ROM-integrated solution would be gone as soon as a new ROM is flashed.

chrome://downloads/ does not available in Google Chrome for Android
I have a Samsung Galaxy Tab s2 and Google Chrome for Android is compatible with my Tab, so I installed it.
I clicked on a link to download a video file. Google chrome showed a toast message that the download has been started.
However, after this toast, I can't find where chrome downloaded the file.
I query chrome://downloads , but the browser displays "This web page is not available "

If you download a non-video file, are you able to download it? The video that you downloaded should be in that same folder.

If not, take a look at this question: http://android.stackexchange.com/questions/49774/how-to-download-via-chrome-on-nexus-7-with-jelly-bean-4-2-2

If you prefer having Downloads be available in the browser menu under 'Downloads'  you can still get that with Chromium. Install the latest build and navigate to chrome://flags. In the menu hit 'Find in Page', search 'downloads' and locate 'Enable downloads manager UI in the app menu'. Enable it and hit the blue button marked RELAUNCH NOW. Now downloads are back in the menu just like old times.

There's a separate Downloads app, which shows a list of downloads from all apps. Downloads are saved in the "Downloads" directory in the SD card, which means that downloaded videos show up in the "Downloads" album in Gallery.

On Android 4.4, you can access the download history in the App titled “My files.”

It's not universal.

Phone wakes when unplugged, how to keep it asleep?
I'm trying to charge my phone with an inconsistent power source.  Unfortunately, the phone wakes up whenever power stops... Sometimes (often) using more power than is charged.
Is there a way to stop the trigger to wake when charging ends?  What is the internal name for this trigger?
My workarounds so far share the same fault:  I can't receive calls.  It can't wake if I turn it off, and it doesn't use too much power (usually) in airplanr mode.

It's probably doable, but I very much doubt that you can do this with the default (unmodified) factory firmware. Custom firmwares such as CyanogenMod may allow you to do this. Your mileage may vary and you may even need to modify or recompile these custom firmwares to get what you want.

I have no idea how to stop that behavior through OS,and I found no reference either. Connect it either to a UPS if the drop out period is long otherwise connect it through a stabilizer if the current drops at a very higher rate, like a blinking of a bulb. Otherwise I don't think it would be good for your phone's charging system.
You could also use USB charging.

I didn't like this behavior either and even though I have a custom (or more like modified) stock ROM (removing the bloatware and rooting it) it didn't change this behavior. However, I found that setting the screen timeout to the lowest value of 15 seconds did the trick in that it would force the phone to go back to sleep by shutting off the screen in 15 seconds after it comes to life, this meant that there was minimal loss of power while unattended, maybe that would help you since there is no way to stop the behavior altogether.

The SnooZy app will let you manage this. (See this answer for details.)

Android tablet separate user account - app installed once or multiple times?
I bought a tablet Samsung Nexus 10, it came with latest Android 4.3 installed. Android 4.2 and higher supports multiple user accounts which is awesome.
My question is, if let's say I have Facebook application installed on two accounts, does it install it two times (taking 2x place necessary) or is it efficient and it installs it once and changes only login settings for separate users?

The second user will have to explicitly install the wanted app (in your example: Facebook) – as otherwise all accounts' app drawers would be cluttered with a bunch of apps not wanted by everybody, except for those who installed them. But if the app already had been installed before by another account, it will rather be a "fake install" (i.e. it appears as if the app would be installed anew, but it's not downloaded again from Playstore, and thus doesn't consume "double space").
One side-effect to that is: whenever a user decides to update the app, that update applies to all other accounts of the device as well.

You can install facebook once and log in with different user/pwd  to have different setting for different account

A couple of points for those swinging in from Google..
Uninstalling an app in one user account doesn't remove it from the other, unless you use Titanium or similar, in which case it is GONE.
If you install an app at the Play Store web site, it installs into the primary user "desktop", even if you are logged into another desktop using the exact same account on your Android device. Theoretically, it should quickly appear in your "My Apps" list, so it's easy enough to install into the second user desktop.
So if you installed an app and see no notification or icon, this is why. Switch to the primary desktop and there it is!

How to stop Viber running without uninstalling it?
How do I stop Viber running, without uninstalling the app? When I go Menu→More options→Exit it just comes back. I want it to turn it off completely, so it's not waiting to come on in the background.

Viber is just bloatware that forces you to use it, you cannot close it, only option is to uninstall.

Oh this is so annoying. I can exit from Skype, from fb messenger, from hangout, from lync. But not from this. Only hard stop of apps helps. Via settings-apps-running

This is an official rep. of Viber.
Due to the C2DM feature, you are always available on Viber, there is not way to  "log out" and "log in".
Please note that if you "exit" Viber, it will open again only if you get a msg or call.
Let us know if you have any additional questions.
Thanks!
Viber Team

Funny!God bless telegram.

Hi @Viber , Can you create an option to disable auto start? It's pointless (and waste battery) to run Viber when there isn't internet. (also I want to use Viber to call others rather than let others call me)

No need to root or anything. You can just simply stop it being running by going to Settings>application>viber>force close this will close all the services related to viber. But remind you, you have to force close it every time after you use viber.
Oh there is another way to do that. Start viber, then close it. Then open your multitasking window/history window by pressing the home button. you should see viber there at the bottom. Long press on the screen-shot of viber. You should be prompted with two option, app details/info and clear from list tap on app details/info and click on force close this will do your job.
Hope that helps.

Just wanted to add that after phone reboot Viber will be running again. So, if you, for example, want to avoid network access by Viber for some reason, then close all network connections before reboot, reboot, disable Viber service and then enable network connections again.

There is an app for this if you have root: Greenify

But that'll require root which will void warranty.

Not really. Well if you are in the EU it doesn't, see this link: http://matija.suklje.name/rooting-and-flashing-your-device-does-not-void-the-warranty-in-eu

This is the way I do it too, but sometimes it still starts up.

I have Viber on phone and tablet and it behaves differently. By default, no matter how you stop the service it always turns on when you receive message.
On phone when I go to settings - general - turn off "show Viber status icon", and then I just exit the Viber (via exit or stop service or clean task manager) I am really offline. All messages are received after I turn on Viber myself. I can be offline for days. It behaves like this only when I turn off the Viber icon.
I guess this is a bug but I like it and hope it is not going to be fixed. I don't know if it is bug just for combination of my phone and Android version or if it "works" like this on every phone. On tablet this does not work, Viber cannot be really off.

Battery saver is the easy option without any additional apps.
Many Mobile manufacturing companies give some inbuilt apps to control background running apps, check if you have one.
If it's a basic stock Android then you need to install 3rd party apps like Greenify or something else..

AFAIK you can't stop the process in the background without unistalling it. You can logout from your viber account, then it won't display you any notifications
// I must add to here, that once you logged in Viber has no known way to log out

How to prevent applications to donwload data automatically?
I have many applications installed on my Samsung Galaxy Tab 10.1. And it always download something from internet, in order to update and upgrade applications. It does it all the day and night, when I am in my home or business WiFi and when I am in mobile network.
How to disable this "feature"? I don't want any blind upgrades, only by my explicit permission.
Also, of course, I don't want to replace numerous downloads with numerous asks for permission.

This is part of Google Play Store settings. Select Do not auto-update apps in the following path:
Google Play Store>Settings>Auto update apps>Do not auto-update apps
This is a global setting, but it may be overridden by a specific setting at the application level. For instance, an application may have a specific setting to update itself, especially if that application came from a 3rd party source. You will need to check those application settings individually and prevent auto-updating there. However, this is not generally true, in fact I think it is a violation of terms, if that application comes from the Google Play Store.

Suspicious directory ".MySecurityData" in internal storage
I have a Galaxy Note (N7000) device running stock Android 4.1.2. I was browsing the internal storage and noticed a directory named ".MySecurityData", which contains one single directory "dont_remove", which contains multiple directories whose name consists of hexadecimal characters of length 32 (presumably MD5 hashes). All those 3rd level directories contain three directories - ".image", ".thumb", and ".video". A search through find command reveals that all the directories are empty containing no files.
Fact that the parent directory is hidden, directories have suspicious and obfuscated names, and a web search returns no results for ".MySecurityData" has raised concerns of some malicious activity.
Can anyone identify the application that may have created these directories? I'm a paranoid person and usually shy away from installing apps, and double check the ones that I'm installing.
There is also a SQLite3 file inside "dont_remove" (name is again in hexadecimal characters of length 15). A SQLite3 .dump on this file results in following:
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE android_metadata (locale TEXT);
INSERT INTO "android_metadata" VALUES('en_GB');
CREATE TABLE medias (_id INTEGER PRIMARY KEY,album TEXT, from_path TEXT, dest_path TEXT,thumb_path TEXT,file_name TEXT,file_type TEXT,file_ext TEXT,timestamp LONG,rotation INTEGER DEFAULT 0);
COMMIT

UPDATE:
After a grep through dumpstate logs in /data/log, I noticed that the SQLite3 file was being accessed by com.domobile.applock. I've emailed the developer asking for more information.

After a grep through dumpstate logs in /data/log, I noticed that the SQLite3 file was being accessed by com.domobile.applock.

Using the ls command, you can find out the owner (and group) of those directories. Following this with a ls on /data, and watching out for the same ownership, you should find only one hit, reveaing the package name of the corresponding app – which you then can use on the Google Play website to find the matching app (by placing the found package name after the id= part of the URL).
As access to the /data directory is restricted, the above commands must be executed with root privileges.

AppLock is a legitimate app, considering that you opted to install it. It allows the device owner to assign a password to any app, settings area, or even Google Play thereby making it possible (for example) to lend the device to a young child without having to worry about the youth accessing those apps, settings or store. The app works as defined. I would therefore not consider the directories as suspicious, if they indeed are owned by AppLock as a previous post clarified.

For anyone else having the same issue, please post a new question and refer to this question as additional context.

I haven't tried this, but since android isn't so different than the underlying Linux system, you might be able to do the same thing as described here. The device file name might be different though and you might need to be rooted.

I found out that the simplest method is to use IP Webcam app. It has HTTP API so you can do all kinds of things with it.
To be fair, I'd also really like to know if there's a way with just shell.

Deleting or listing least frequently played songs in Google Play Music
I'm starting to hit the limits of my storage space. My device is mostly filled with music, so I'd like to remove songs I don't listen to anymore, without having to painfully scroll down the list and delete them one by one.
Does Google Play Music have some way to at least list the least frequently played songs, or is there an additional music management app I should know about?

No there's no feature in Google Play Music that lets you delete songs you don't listen to. AFAIK there is no app that does the same too.

Uh, that's too bad... I'll write an app for that then! :)

Samsung Galaxy encryption failed
I updated my GT-19100 Phone to 4.1.2 Jelly Bean from the previous version. For this venture it was necessary to decrypt my phone first. After the update I started again an encryption. The process failed (i just left the encryption continue by leaving the phone alone) and the phone showed me this message:

After reseting the device I can't access any previous data on the phone, nor can I save something on the phone. The phone recommends to format the device.
Is there a way to get my old data back? How could I avoid such a problem next time?
Any advice appreciated! Thanks in advance!
Similar to this question: "Encryption Failed" on my Samsung Note 2 & it asks me to reset device. Is there a way to back up my data But still not answered.

If you clicked "Reset device", then it erased all your data as it claimed, and no, you can't get it back.

Ok, thanks. Probably I should do next time a backup.

Sony Xperia L device memory is being eaten up
My phone's /data storage is getting fuller all by itself even though I have not installed much apps. By doing some search on net have found that there are folders under Data folder such as tombstones, thumbnails etc. which are taking up the space but which are not accessible without rooting. I want to clear up this space without rooting the device.
My device is a Sony Xperia L running Android 4.1.3 Jelly Bean)

It needn't necessarily be tombstones and thumbnails that takes up your phone's data storage.
Normal app usage (mostly browser cache, etc.) also consumes space over time.
Have a look at
Settings->App->All apps

then via menu let them Sort by size to see the biggest storage consumers.
E.g. my phone's biggest consumer is Chrome (123MB data, 280MB cache):
.

have done all these things ...that is not the issue..i have done factory reset more  than 5 times but this issue does not get resolved..

Free up space on the internal SD card folder.
With Jelly Bean the formerly separate SDcard data is also stored on /data (/data/media to be precise). Free up some space there, it counts to the overall sum on /data.
Reason: /data and the external storage partition have been merged to only have one partition and benefit from a single storage scales better. It removes the need to choose a reasonable hard partition size split for /data and /sdcard as before. For compatibility reasons, the /data/media folder is exposed via a virtual fuse layer that emulates the former FAT properties and hides the internal structure from apps. Android Police has an interview why this was done here.

How does Android measure connectivity state?
I know Android has some sort of connectivity measurement, because when there's connectivity the wifi or phone network icons will turn either green or blue, depending on the Android version.
In my opinion, this measurement isn't perfect, because although it will indicate accurately the absence of connectivity (e.g., lost wifi connectivity), it is not so accurate when the phone is connected to the Internet: at work, my Defy running Cyanogen 9 (Android 4.0.4) has icons that are always gray, no matter what, even when the connection is obviously up (see image below).
I wonder how, exactly, Android measures the connectivity status. Is it by performing a ping or other sort of probing of a server? By listening to a port? By testing if some protocol is enabled? Or what? This accepted answer to a closely related question doesn't seem to answer it.

I'm not sure I understand how your situation is differnt than the other questions. The second question in particular describes the exact same symptoms. The Internet works, but the icons are gray because the icon color is only an indication of your connection to Google's services, nothing else. It could be that your office network is somehow restricting your access to Google's services, but not the Internet at large. We'd probably need more information to make that determination, though.

@eldarerathis The accepted answer says "the phone is connected to Google services", but it means nothing to me. Is there a specific server it contancs? A specific protocol? Port? What?

I have now completely rewritten my question. I believe it's more clear now, and hopefully won't be closed as a duplicate.

As it now is a completely different question, we should all go delete our comments, answers, votes, whatevers. Unfortunately, at least for the last two items that's not so easy; so maybe next time you consider starting over with a new question and delete the old one. Changing a question this drastically when there are already answers might make the answerers (and commenters) look stupid ;)

See also How do I make Android consider my WiFi Access Point as valid (blue?) which mentions opening tcp-udp port 5228. Or What Android versions have captive wifi detection? which has links to some of the code

@GAThrawn: Amazing! That's really close of what I wanted, specially the first link. Thanks for including even the captive portal detection, going beyond the original question. If you elaborate it just a little bit more and turn it into an answer, I'll accept it!

Note: As of Android 4.4 (at least in the unmodified version) the icons will always be white. You need to open the settings pull-down menu to see if you have a "good" connection.

All of the information about it is pretty vague. Probably because they don't want people attacking a particular Google server.
For instance, the Samsung Galaxy Tab 10.1 owners manual has this to say:

Note: Network status icons turn blue if you have a Google Account added to
  your tablet and the tablet is connected to Google services for syncing
  your Gmail, Calendar events, contacts, backing up your settings, and
  so on. If you do not have a Google Account or if, for example, you are
  connected to a Wi-Fi network that is not connected to the Internet, the
  network icons are gray.

I wonder if it is possible to use mobile packet capture to identify it better?

Does Android 4.2 support IPsec IKEv2?
Does Android 4.2 support IPsec IKEv2?
If not, does any other version of Android support IPsec IKEv2?

Being a strong supporter of the AAAAA, I took the freedom to link your abbreviation to an explanation. Hopefully I've picked the right one...

Android 11 is slated to be the first release to include support for IKEv2. There are some comments from a Strongswan developer about the implementation in the preview build here: https://android.stackexchange.com/a/225383/3183

No Android version natively supports IKEv2 yet. But you can install the free and open-source strongSwan VPN Client that uses IKEv2 and runs on Android 4 and newer.

Does it work with a non-rooted device?  Once installed and appropriately configured with IKEv2, is it otherwise functionally equivalent to the native VPN feature?

The app uses the VpnService API so it should run on most devices without having to root them. There are some differences in the feature set, for instance, the always-on VPN feature provided by the native client on Android 4.2 and newer is not supported (but the app tries to keep the connection up once it has been established).

How to access media files (photos and videos) on Samsung GT-I9082?
I have a Samsung GT-I9082 mobile phone (Android 4.1.2) with lots of videos and photos. I want to move them from the phone to my notebook running Windows 7.
I connected it via USB and selected the MTP mode. I got an error on the phone, which said that my notebook is not compatible with that mode.
So I switched to PTP mode ("Connect as a camera"). Then, the notebook recognized both the device and its memory card.

But I couldn't find video files neither on the device itself, nor on the memory card. Searching for *.* shows just 4 files, and their total size is less than 10 GB (this is the occupied space on the memory card according to previous screenshot).

What can I do in order to access these media files on my notebook?

Did you not look inside the card folder?

@Sid I looked into every folder, which was visible in the Windows explorer. I didn't find not a single video in any of them.

Well, this does not really answer the question, so I'm posting it as a comment. It might help you solving your problem. Let us know how it went.

did you tried to use the SD card which you use for this device in card reader?

@h4cky Not yet. My notebook doesn't have a SD card reader.

You can try Airdroid for fast file transfer from Android to PC over WiFi. Install it in your phone, turn on mobile hotspot and connect your PC to your local network. After that, Airdroid will give you an IP address. Just open it in your web browser of your PC, and you will get a nice file manager to access files.
If you have access to adb shell, you can also use 'adb push/pull' commands to copy files to/from your Android.

Have you tried "Showing Hidden Files and folders"? :

"Follow these steps to display hidden files and folders.

Open Folder Options by clicking the Start button Picture of the Start button, clicking >Control Panel, clicking Appearance and Personalization, and then clicking Folder Options.>
Click the View tab.
Under Advanced settings, click Show hidden files and folders, and then click OK."

windows.microsoft.com

Here is a step by step guide on how I took the photos off my Galaxy s4:

Connect via USB (There should be an option in the notification center which looks like this)

Tap on it and it should bring you to another menu which should look like this:

Select Camera (PTP) and move to your computer

In windows explorer under "My Computer" it should appear similar to this:

Next select your phone and it should give you two options. If in your camera settings you've decided to store to Card then select that.

Next select DCIM

and then the camera folder

Your photos should be in that folder!

Hopefully this worked for you. I'm guessing the samsung phones have similar directory setups considering they're from the same manufacturer and both are running android, although I'm running a slightly newer version.
edit: After reconnecting a couple times I ran into the same problem and fixed it by reconnecting again and before accessing the folders letting it sit connected for a minute.
Also, If you're sorting the folder by file type the videos will probably be at the bottom of the list under all of the pictures.
ANOTHER way you can possibly get the photos on the computer and the way I personally use is using dropbox camera upload feature. Just download the dropbox app on your phone enable photo uploads and download the desktop app fr your computer and every photo you take will be automatically uploaded to dropbox so you can't lose it and it will be on your computer within a couple seconds to a couple minutes depending on your connection. I use this over connecting and copying over because I found connecting it to be a little glitchy.

With Camera Upload, the photos and videos you take with your camera, phone, or tablet
  will upload automatically to Dropbox—meaning they'll be safely backed up and viewable
  anywhere.
Take advantage of Camera Upload in two ways:

Upload wirelessly from your phone or tablet using the iOS or Android app
Upload by connecting your camera, phone, or tablet to your computer and using the Mac > or Windows desktop app

dropbox.com

The DCIM/* folders are visible, but they don't contain the videos.

I made an edit to the original answer.

I've got the same issue on my I900P (running 4.1.2), and your answer works just as advertised up til step 5, where I don't see anything for the card contents, just for the camera.    However unfortunately I use an SD card for pictures to conserve memory.    But this is invisible to the explorer window view of the camera.  Any tips on how to sort this?    tx

My answer wont solve your USB connection problem, but as i read your request, it seems that you only want the files sent to your computer and that this is the main reason you made this question.
Since you are saying that you have lots of photos and videos on the phone, i assume that you can access these from your phone trough Android.
If i was you, i would skip the USB problem, and then connect to the computer via WiFi.
The most simple way to do this, i think is to connect to the WiFi network. Install Dropbox/Google drive or any other similar service on your computer. Install the app for the same service on your phone. And then go into your favorite photo browser/gallery and send the files over to the service and then you will have them automatically on your computer(if you have installed the applications).
This also gives you a backup of the photos and videos. (If you have had this backup today, you wouldn't have to worry about getting the files out from your phone) :)
Simple steps one by one, with my recommended service:

Connect to WiFi with your cellphone
If you dont have a Google account, make one here: Google Signup.
Most likely you have a google account, when you have an Android phone. Otherwise, you can not download apps through the Google Play.
Install "Google Drive" on your computer. You can download it from the google drive download page.
Install "Google Drive" on your phone. Download it from the Google Play store.
Go into your favorite photo browser or gallery app on your phone. You can then select all files or only the ones you wanna transfer, and choose the "share"() button and choose "Google Drive". It will then use some time depending on the internet connection you have.
You can then go on your computer and find the files inside the "Google Drive" folder.

Your files is now safely saved/backed up on three devices. Your computer, phone and "Google Drive".
I hope this solution works for you.
You can also make a permanent solution by downloading and using FolderSync wich will automatically upload photos to Google Drive when you take photos or videos.

Looking at given screen shot suggest there is some sort of virus issue with your notebook or the phone itself is infected

I doubt it because I tried it on 2 different notebooks and it never worked.

@DmitriPisarenko yes you are right i interpreted it wrong.

Instead of Using MTP or PTP Scroll down your notification and pressUSB Connected and Select Turn on USB Storage then your SD card Connect To your Laptop Like a Flash Drive And you can Copy Your Media From it.

This is just a workaround, but one that worked for me:
Use an Android file manager such as AndroXplorer to rename the video files. When I did this, they appeared for me in Windows Explorer and I could copy them as usual.

Can my Samsung Galaxy Nexus and iPhone 5 share same micro USB charger?
Does the micro USB charger cable that comes with the Samsung Galaxy Nexus be used with the iPhone 5 and vice versa?

Technically yes, but you need a Lightning to micro USB adapter, like this one.

The iPhone 5 uses a lightning cable.

Meanwhile, the Galaxy Nexus uses a micro USB cable.

As you can see, they're quite different.

The USB 2.0 specification define that the USB 2.0 voltage is 5V so if you have the Lightning to micro USB adapter you won`t experience any problems. But directly conecting the micro USB from your Samsung Galaxy Nexus wont work.

samsung galaxy nexus charging problems
it doesn't charge until battery totally dies and few minutes after that only, charging triggers.
Not sure if it an issue with charger or the phone battery.

Have you tried using a different charger? Or charging through the PC's USB? Or maybe a different battery? [Just to rule out some of the issues]

doesnt work using PC's USB...I dont have extra battery...most likely an issue with the cable...I will check

Slideshow wallpaper using files in hidden folder
I've got some nice photos in one folder and their specially cropped versions in another hidden folder (the name starts with a dot).
How can I use the cropped photos from the hidden folder for a wallpaper slideshow? No matter what app I try to use, it doesn't allow me to use the hidden photos. I don't want to make them visible; I don't want duplicated photos in my gallery app.
Is there any way / app that would allow me to use the hidden photos for a wallpaper slideshow without having to make them visible in my gallery app?

Android treats filenames that start with a dot as hidden. So, there's no way for any app to show them. However, you can still see them on a file explorer that can see hidden files (may need root access).

So there is no way to do what I wanted to do?

@burtek Most likely, no. I think it's only natural for apps to respect the hidden property.

Does a malicious android WebView break the DoubleSubmittCookie countermeasure against CSRF?
Initial situation:
A RESTful webservice defends against CSRF attacks by using the double submit cookie approach. This means that the authentication token gets submitted twice and verified at the service side.
Problem / Security Threat:
The WebView element of the android and iOS plattforms allow to create a malicious web browser that unveils and modifies session cookies. webView.loadUrl("javascript:document.cookie=’’;");. If the attacker already figured out, how the double submitted cookie looks like, (In this case it's the AuthenticationToken) he is able to create a malicious RESTBrowser. Therefore he adds the already known CSRFToken to the document object model and thus bypasses the CSRF countermeasure. Is that right so far?
Possible Preventions:
So far I have no idea how I can prevent an attacker from creating und publishing such a malicious mobile application, as well to prevent the service from beeing accessed via malicious mobile applications. I know about the existence of the User-Agent header and that the service can use this information to reject requests from others than specific browsers. But I'm sure that also this header can be manipulated within the WebView.
What are effective countermeasures aginst CSRF in contex of malicious mobile applications?

Better ask over at Stackoverflow using the android and security tags. Devel questions are considered off topic here as this site focuses on end user problems.

or Security

Does a malicious android WebView break the DoubleSubmittCookie countermeasure against CSRF?

Short answer: no.
Long answer: CSRF exploits the trust that a site has in a user's browser. CSRF protection is not intended to protect the server from a malicious user agent or from an untrustworthy user. The user is responsible for choosing a trustworthy browser.

Quickest way to toggle between apps (Alt-Tab equivalent) *not* requiring 3rd-party apps?
There seem to be a handful of apps with this functionality in mind, but I'd prefer an inbuilt solution. (I'm on the S4 mini)

See also here.

There is one way not requiring third-party apps: long-pressing the home button.

Yes, 've come across that one. This is currently the best way I know of, but it's not very quick...

In fact, this is not a real "toggle", but rather a (potential) shortcut to (slightly) expedite slowly tapping your way from one app to the next (and back again).

@nuttyaboutnatty I'm afraid I don't see the difference. What do you count as a "toggle" other than switching from one to the next?

Instant switching. (Like in Windows and Linux Alt-Tab or Linux workspace switching.) I'm trying to speed things up on my S4: maybe this will also help speed up your suggestion: http://android.stackexchange.com/questions/55060/how-to-disable-shortcut-to-launch-samsungs-s-voice-without-accepting-its-to

If you use a phone with a dedicated task switching button (like the Nexus 4) it's way faster. Takes about 0.5s there.

I believe what @nutty wants is a way to instantly switch to another app that he wants without viewing the multitasking menu/screen. I also think that Dan's answer is the best answer to the question, since there's no real way to do that without an app or modification.

cannot send mail via 3G with outlook exchange sync
i have a android 4.2.2 phone. i cannot send an email via 3G with outlook exchange sync. If i try that, he will wait until its connected with wifi, and than send it.
synchonising calander / tasks, incomming mail on just 3G is not a problem, just sending email with 3G in outlook exchange active.
Gmail, internet work just fine.
the same account on IOS is not giving any problems.
can anybody help me?

Is this using the stock Email app?

I would guess there is a setting issue in the APN
Check your setting in APN with you phone company

If that would be the case, incoming mail wouldn't work either, nor would synchronizing calendar and tasks – which do work, as the question describes.

Missing 'Contacts' sync App
Am running Android 4.2.2 on a CUBOT smartphone, but cannot sync my contacts from Gmail as the ONLY sync adapters showing in the Settings-Accounts-Google section are 'App Data' and 'People details'.
Both these apps, if un-checked then checked pretty much instantly come back with a 'Last synced 14/10/2013 09:38' (or whatever time date-stamp is accurate), but nothing seems to have changed.
I seem to be missing just a plain old 'Contacts' sync option.
Being new to Android - I haven't a clue how to progress, or where to download/install 'contacts'. Advice greatly appreciated.

Try haxsync. It's the best. It's working on Android 4.2.

The question is about syncing Gmail contacts, and haxsync appears to be only for syncing Facebook data, so your answer doesn't seem relevant.

I've had the same problem but using CCleaner I solved it. I had too many registers of calls. Cleaning for 3 hours with CCleaner was the solution.

This doesn't make any sense -- what is "I had too many registers of calls" supposed to mean?  And why would CCleaner fix the issue?

How to disable shortcut to launch (Samsung's) S Voice *without* accepting its ToS?

By default, when you double-tap the home key, you'll launch straight into S Voice.

To disable that shortcut, one could

load S Voice, then press the menu key and hit "Settings." Next,
  uncheck "Open via the home key." That's it -- with the shortcut combo
  disabled, the home button should respond immediately as opposed to
  with a very slight delay.

However, this method seems viable only once Samsung's Terms of Service (ToS) have been accepted - only after which S Voice will launch fully. Any way to disable that key combo without having to accept ToS of a S I do not want?
Note that at this stage I do not (yet) want to uninstall S Voice. If you happen to know how to uninstall it, I'd appreciate a comment, though :-)

I just disabled S Voice entirely for now, as explained here and elsewhere:
Application Manager >> All >> S Voice >> Disable, then reboot.

Getting rid of stale notification icons in the notification _bar_?
How can I get rid of notification icons for Skype in particular, but any app in general when the app was killed using one of the many available task managers, but the notification icon still remains on the notification bar (that is the part that is persistent at the top of the screen in Jellybean)?
Device: Nexus 7 (2013), Android 4.3

What's wrong with just dismissing the notification in the usual way?

@DanHulme: hmm, perhaps my question is wrongly worded then. The problem is the tiny icon that sticks at the top even when the notification bar that can be pulled down further hasn't been pulled down. This kind of icon also shows with system updates. Only difference: you cannot dismiss this one, as there is no item in the pulled down notification bar to dismiss.

Why use task killers in the first place?  Any Android device running 2.2 and above should be able to manage its own memory properly.  Especially a modern device such as your 2013 Nexus 7.

To quit the latest version of Skype just tap the on-screen menu button (3 dots) from any Skype screen and choose the "Sign out" option.

@DanHulme it's not about notifications in the notification area, but those icons sticking in the notification bar (opposite to the connection indicators). To the OP: Why not simply use the Logout functionality of Skype? AFAIK that should not only remove the icon, but also "really quit" the app, so you wouldn't need to "kill" it. Please report back if that works: if so, I would make it an answer (currently it's just a guess, as I avoid NSA software as best as possible and thus cannot verify myself ;)

@Izzy: the actual problem turned out to be finding that option ;) ... see http://android.stackexchange.com/a/55077/9993 ... they keep changing where the Signout is. I'll leave the question, since I've had this with other programs in the past, so a solution is desirable regardless of the Skype issue being resolved now.

OK, so as this question is intended to be more general (concerning the "Service-is-Running" icons), it's about finding the similar option in all kind of apps? That would make it too broad to fit here. What kind of answer you're after, then? Solutions requiring root and working independent from the app in question accepted as well?

@Izzy: why is it too broad to answer if it's about notification icons in the notification bar. That's like saying a question about how to install an app from the Play Store is too broad. The notification icons are a common trait of apps and they can become stale, so what exactly makes the question how to get rid of stale icons "too broad"?

Because you "get rid of those icons" by closing the app correctly. So if we should describe that for every app that might place an icon there, it would be quite extensive. Of course the easy answer is: "close the apps correctly" (not shoot them down), because then they remove their icons themselves.

@Izzy: that's a silly remark. Obviously if I ask to get rid of stale icons I mean stale icons and that is a generic thing to do after the fact, i.e. when you have the stale icons. And I think it's warranted to ask for a solution other than a reboot. It is certainly technically possible there is something like an "icon swiper".

How to access a memory stick using a OTG cable?
I have a OTG cable connected to my phone and a memory stick on the other end. My android phone is rooted and I have no idea how to find/access the files on my memory stick. How do I access files from my memory stick with my phone?
EDIT: Is it also possible to watch videos from the memory stick without moving it to the phone's storage?

You can access a memory stick via OTG cable if your phone supports it. See Compro1's answer to check if your phone supports OTG; you may need to specify the correct code / model in the USB Host Diagnostics site.
In case your phone supports OTG but does not support it directly, check out my answer which involves using USB OTG Helper.
As to your last question, YES. You can watch videos from the memory stick.

Android phone wi-fi not connecting with perticular network only
Please refer me to right portal if this is not a right one.
I am having android phone HTC one +. Now problem is that when i am in office and trying to connect with Wi-Fi then it not connect but when i try to connect with any other Wi-Fi network then it easily connect.
I also had visit the service center and Wi-Fi connected easily in their network.
What i can do to solve this issue.

Yes, Actually My Mobile was blocked in the office network due to some security issues. I consulted with the Network team and they release access for my phone.

I had the same problem but with another device(HTC touch diamond2). You need to edit network settings. Write by yourself IP-adress, subnet Mask, Router of current Wi-Fi.
I think to find out this information for you will not be difficult.

Please provide me more info to solve this.As i also concerned with the network administrator they are saying they didn't applied any security on this network.

The reason isn't in network security. Open wi-fi settings(where you are searching networks) - > find current network and press on it for a long time - > Edit Network - > Show advanced options -> IP settings choose from DHCP to Custom - > Write IP-adress, Gateway, Network prefix length(Your network administrator must give you this info) -> SAVE.
Everything must work ;)

Thanks David for this i will try this and let you know ..

What is the dalvik speed patch?
Lately I've been hearing about a dalvik speed patch to supposedly increase the interpreting speed of apps through the dalvik JVM. The only mention on Google is Facebook's "hack" of the dalvik JVM to allow the Facebook app to install on legacy phones. I am sure this is not a dalvik speed patch.
Post where the patch is briefly talked about:
"New score...PA 3.99 RC2 + Franco r184 + dalvik speed patch.."
https://plus.google.com/105415059081329756565/posts/4i8GDm47bnv
So what exactly is this dalvik speed patch?

This question appears to be off topic because it covers a very niche topic that can only be answered by the author of that post (apparently he did answer it in the comments if you've read the G+ posting).

There's absolutely no magic here caused by a mysterious "Dalvik Speed Patch". The Author said that in the comments himself by stating:
Lol... I just mention dalvik speed patch, actually it's a kanged lib file...

So it's just a wording issue that you took as a rumour.
The higher Antutu benchmark scores are very propably caused by overcklocking using the Franco Kernel only.
Regarding your second thought about the FB hack:
The FB hack has has nothing to do with this question. By the way, it's super ugly and something Facebook should be ashamed of: http://jaxenter.com/facebook-s-completely-insane-dalvik-hack-46376.html

Safely "unmounting" USB for Galaxy?
I wanted to delete all of the music (not pictures or apps) off my phone, and I read that you should just plug it into the computer and delete them from there. I plugged it in, and though my phone is charging, it hasn't recognized my device. I want to unplug it, but there is message warning me to unmount the USB before I unplug. Will it delete all of my memory if I do? Can I just back up and reset my phone while in this mode, or will my things be deleted?

No, nothing will be deleted if you chose to "unmount" first. As your device was not detected, it should not even be mounted, so there's nothing that could "break".

A short explanation on that "mysterious unmount", though:
If your device is "mounted" (i.e. you can access its files from your computer), for faster reaction and other performance reasons all data transfered is "buffered" (instead of being written to the storage immediately). So "unmounting" tells the system to "flush" those buffers, and thus "commit" (write) all buffered data to the storage.
If you would simply "plug the line" without unmounting first, not-yet-written data were lost. Imagine what that would mean if some larger file was only written partly (it gets corrupted), or if you moved files to the phone which where not yet written at all (they are "lost in space").
So it's always a good safety measure to "unmount" first before plugging out the cable.
