Phone restarting over and over after rooting Samsung Galaxy Ace S5830i
I rooted my Samsung Galaxy Ace S5830i from the link given below-
http://theunlockr.com/2012/11/22/how-to-root-the-samsung-galaxy-ace-s5830/
However after rooting it, it is restarting again and again.
I unrooted it but still the same problem exists.
I even factory reset my Android phone. But still the phone restarts!

That very much looks like the rooting process messed up the /system partition (otherwise, the factory reset should have sorted things out). If that's the case, you might need to flash a fresh firmware (stock or custom -- the latter would need root again).

If you have a bootloop (samsung logo looping), it is because you messed up the rooting procedure. I had this problem when I tried to root a relative's Ace.
Since you've tried factory reset and it doesn't work, enter recovery mode and do factory reset. (recovery mode: press and hold volume down + power button for 15 seconds, navigate up/down by volume button and power button to select). Reboot and see if it fixes the issue.
If it does not, there are two options: flash CWM from recovery (here's the CWM zip file to flash from stock recovery), then reboot to CWM and install a custom ROM. This is what I did, as I wanted to load CM7 anyway.
If you want stock, download Odin, get stock firmware from sammobile.com or XDA forums (look for Developmet section under your device specific forum) and flash it.

Thx..it did solve the problem but once I switched it off and started it again..it started rebooting again and again!Before switching it off, it did not had that rebooting problem.Is there any way out?

Describe what you did - factory reset, flashing custom ROM through CWM or stock ROM through Odin?

I flashed custom ROM through CWM.

Did you flash the custom ROM after doing a data wipe? If that doesn't fix it, you'll have to flash stock firmware through Odin. Be careful and make sure you pick the firmware specifically for your phone, else you'll brick your phone.

Intel HAXM and Host GPU on Mac OS 10.8.2 (NVIDIA)
I installed HAXM 1.0.4 and I cannot run Android emulator with option 'use host gpu' checked, it shows cyclic GL_* errors. I am using Mac OS X (mbp with NVIDIA GeForce 320M). Without gpu emulation everything works fine (well if word fine can describe that slow piece of software).
I have 8GB RAM, HAXM set up to use 1024MB. My virtual devices set up to use 512 MB (I have tried different values, but less then 1024Mb, according to HAXM doc).
Here are the error messages which are output periodically (emulator shows black screen)
(complete log)

Also I tried to set LD_LIBRARY_PATH to <sdk install location>/tools/lib and that doesn't help me either.
They say "Make sure that your environment variables for the GL libraries are set correctly". How can I check this? Other programs are working well. Without HAXM GPU acceleration is working well.
Screenshot from emulator:

I should also add that errors occur only with Intel 2.3 x86 system image. With the newest 4.1 everything works fine.

When is the error shown exactly?  How much RAM do you have?

@MatthewRead Error is shown a few moments after I press "Start" button in AVD manager. Please take a look at updated answer, I added error log. I've also seen similar error messages on the web, however people got this error when emulator was already loaded and then were trying to launch some apps which requires ogl.

Hmm, assuming those are from the emulator (rather than Android) you might want to try running it as root or seeing if everything under the emulator directory can be granted more permissions....

@MatthewRead still no effect (tried to run it this way: sudo ./emulator -avd Nexus_Intel_23) - emulator shows gibberish on the screen (inserted pic in question body)

Wow, other than graphics driver problems I'm out of ideas but I don't know how those work on Mac (and it seems like there's more going on anyways).

@MatthewRead I made fresh install of system today, so at least I am not guilty :) I'd be glad if someone could add tag haxm so that other mac users would tell me if they have same problems (seen same in comments on intel's page). Also in docs they say to set up LD_LIBRARY_PATH to <sdk install location>/tools/lib and that doesn't help me too. They say Make sure that your environment variables for the GL libraries are set correctly. How can I check this, what do you think they could mean by "correct" set up of GL? :)

I have no idea on that unfortunately.  You don't have anything else like VMware or VirtualBox installed, do you?

I had VirtualBox installed, but I removed it completely and rebooted system. Still no changes.

Why don't you try running it on a different OS? Dual-boot linux (probably Ubuntu) you'd be able to find much more info in the community forums and/or their official documentation.  I doubt that this has to do with your device, more likely some missing dependencies on your host system. (sry, I wasn't "allowed" to add this as a comment :-(  )

Additionally, in your last line of the question you mention that in the 4.1 image everything works fine, whereas in the intel 2.3 x86 image it does not.  According to the documentation, graphics acceleration is supported in SDK Platform API 15 revision 3 (4.0.3) and higher.  Assuming that your remark about intel 2.3 x86 and 4.1 refer to Android version 2.3 and 4.1, respectively, this would be in line with the android documentation.
Furthermore, take a look at the Android Project Issue Tracker for similar bugs and updates.  There's also a pertinent question on StackOverflow with some useful suggestions and user activity.

Disable SMS Syncing on Outlook
I've already asked this question on Superuser (given it's Outlook related), but now I'm trying to see if anyone else on Android Enthusiasts can help me. The details are as below.
I've paired up my Samsung phone with an Outlook Exchange inbox (probably Outlook 2010), and now I've got the outstanding SMS syncing feature. Only, of course, it sucks, since my inbox get's flooded with SMS's that I already have on my phone.
After looking around the internet for quite a while for a option that would allow me to disable that kind of syncing, the only guide I got was designed for Windows Phone 6.x.
I want desperately to disable it. Anyone has any clue as to how?

I had the same problem and think I found the place to correct it:
1) Open the e-mail client program on the Samsung
2) Go to "menu | account settings"
3) Disable SMS-sync
Hope it works!

Thanks! It's exactly what I needed... I can't believe I missed it. I was looking for it in outlook ins tead of in the phone settings.

What is the criteria that Android depends on to join contacts from different accounts?
I'm synchronizing my contacts from many accounts (Hotmail, Facebook, Gmail), everything have worked well and the OS has joined (or shows them as one) the accounts that refer to the same person. But not all accounts, since some accounts have not been joined although both accounts have the same name and one email exists in both as well.
I wonder what is the criteria that Android depends on to join the accounts?
Note: I do know that I can join them by myself in the contants list, but I would let it know them by itself.

Raw contacts are joined according to rules described at Using the Contacts API:

Two raw contacts are considered to be a match if at least one of these
  conditions is met:

They have matching names.
Their names consist of the same words but in different order (for example, "Bob Parr" and "Parr, Bob")
One of them has a common short name for the other (for example, "Bob Parr" and "Robert Parr") One of them has just a first or last name and it matches the other raw contact. This rule is less reliable, so it only applies if the two raw contacts are also sharing some other data like a phone number, an email address or a nickname (for example, Helen ["elastigirl"] = Helen Parr ["elastigirl"])
At least one of the two raw contacts is missing the name altogether and they are sharing a phone number, an email address or a nickname (for example, Bob Parr> [incredible@android.com] = incredible@android.com).

When comparing
  names, the system ignores upper/lower case differences (Bob=BOB=bob)
  and diacritical marks (Hélène=Helene). When comparing two phone
  numbers the system ignores special characters such as "*", "#", "(",
  ")", and whitespace. Also if the only difference between two numbers
  is that one has a country code and the other does not, then the system
  considers those to be a match (except for numbers in the Japan country
  code).
Automatic aggregation is not permanent; any change of a constituent
  raw contact may create a new aggregate or break up an existing one.

There is also explicit aggregation, that can be set for raw contacts, if a user explicitly wants two contacts to be joined. Read more about it in the article.

How to fix my multiple account sign-in issues?
I have multiple accounts active on my phone. I started by using my custom domain Google account, because it had my contacts. When I got on Google+, I couldn't use that account, so I had to link my normal Gmail account with my phone. And when I added my YouTube account, it threw that account on there too.
Now, in intervals that range from every few days to every few minutes, i get a notification
that says "Sign In error with account (account name here)", then asks me to enter a capcha-like entry (enter letters of distorted words).
It usually happens to the standard Google account (@gmail.com), but has happened with all three at one time or another. Anyone know why this would be happening?

According to this forum deleting the YouTube account resolves it.

what if i want to upload videos to youtube? would i have to sign in every time and sign out when i'm done?

Guess so. I've don't really upload to YouTube so I'm not really sure.

Multiple update notifications from Android Market
I have recently upgraded my HTC Desire to run CyanogenMod 7.  The main reason I did this was so that I could use a more recent version of the Android Market that supported multiple accounts.  The reason for this was that I have moved my email address from GMail to Google Apps for Your Domain and wanted the main email address on the phone to be the Google Apps one, but the market to keep using the gmail one so that I don't have to buy apps again.
I also have two other gmail/apps accounts configured on the phone (so that I can receive emails sent to these two accounts).
Generally, everything works fine and I'm really happy with CyanogenMod.  However, I have one fairly minor problem with the market.  When new updates are available to the installed apps, I used to get a notification message saying (e.g.)
2 New Updates are available

(I'm paraphrasing as no updates are currently available, so I can't remember the exact wording of the message).  This is quite instructive.  With the new market, I get FOUR notification messages:
2 New Updates are available email@mydomain.com

2 New Updates are available other_email@mydomain.com

2 New Updates are available more_email@gmail.com

2 New Updates are available email@gmail.com

This seems a bit daft as they're all the same updates!  Is there any way to sort this out?  The market is set up to use the email@gmail.com account, but seems to be checking for all of the accounts.  I'd imagine that if there are paid apps that need updating, they'll only be listed for the last account (although that's a guess), but for all the free ones I seem to be stuck with multiple messages.

I guess this is by design as the majority of users don't have 4 accounts on their phone. The whole idea of those messages is to give the user the opportunity to download a new version as soon as it comes out. You may not want to use your mobile data when you don't want it to. Maybe the update automatically tickbox would bypass this message, however it will probably still say that 3 updates have been applied.
So what you maybe looking for is silent updates https://stackoverflow.com/questions/10328471/can-we-do-silent-updation-for-android-application looks like you can do it with a rooted phone.
I too think that Google can handle multiple accounts in a more intuitive ways across their products. Since its out of our control to improve these closed source apps ourselves I will say its better than it used to be. I think the best solution for Google would be to combine these messages into one notification ie "5 apps have been updated".
Make some noise on the Google support pages to improve this UX, this may be a good start http://www.google.com/support/forum/p/Google+Mobile/label?lid=551c5c4cca827a18&hl=en

How To Sync Data From Specific App(s) Across Multiple Devices
I know some are going to skip over reading this and just think this is regular Android syncing, I can assure you this isn't the same. I'm not talking about sytem, email, social media, or calender apps. Most normal user apps don't sync data between devices. I'm not developing anything, so this question is posted from the viewpoint of an end user.
What I am trying to figure out
How to sync data from a specific app to all my devices on my home network, without manually entering the data?
(For Reference one of the apps I want to sync data from is ShowBox. There are others, but I would be able to duplicate the solution provided)
Steps I have taken so far is to

contact developer(s)/no luck
write a script/no luck
get an app/no luck
researched/no luck

The answer I'm looking for will be basically non-device specific, but for sticklers at least for Android 4.1 and up. If the answer includes an app or other method, please include details with step-by-step instructions. EDIT Please don't include steps or apps that involve user interaction everytime, because I could manually transfer the data myself just as easy. One last request, it must be done locally. Not online, but do on home network.
EDITED PER REQUEST
In the reference (example) app above, the data I wish to sync would be watched videos and favorites. User data. Like stated above there are other apps I would also use the same solution/steps on.
Also if there is a way to automate the syncing.

Now you're a bit vague when you say data but if I know what you're talking about then I would consider an app called OneNote by Microsoft.

You need to have a Microsoft account. Go to Outlook and sign up for an email there. You don't have to use that email. It just links all the Microsoft apps together.
Once you have created the email, download OneNote, both on your computer and all your other devices. Sign in with the email that you have created.
It will give you plenty of features in which you can sync all your information that you need across all of your devices. For example, I have it on my phone and when I take a picture it is uploaded to OneNote and I can automatically see it on my computer.
It will also sync all sorts of information and data that you need such as important documents like word Excel and PowerPoint and even video.

There are also a few other apps that can do the same thing.

I edited the question to reflect what data. I need a way to do it locally on home network, not online.

Its not the answer I need, so its not accepted. But I can use this for something else I want to do so +1

What are those others apps you think can do this? Can this be done locally?

This answer really doesn't address syncing data, and won't help others looking for a solution.

You're a bit vague. But I think you are talking about application back-end datas. This is possible. You may want to use an app like Helium and Dallas Thomas explains how to use it in this article: http://gs5.wonderhowto.com/how-to/back-up-your-android-apps-their-data-without-root-0158767/
In Helium you just select the app data you want, find the apps and choose cloud backup.

Please include steps in using the app, so others can follow along as well.

Is it safe to swap SIM cards when the phone is turned on?
On my Galaxy Nexus, I can remove the SIM card without removing the battery. I'm travelling abroad and will find a need to swap SIM cards several times in my phone. I would like to know if it is safe to simply pull one SIM card and put a different one instead, without shutting down the phone?
Safe = without damaging/locking/corrupting either the SIM card or the phone.

I disagree with Michael that there will "likely be trouble", but I'd guess it's likely not to work.  I've only got by Galaxy S to accept a SIM hot-swap once, and I have no idea how.  Every other time I've had to reboot.

I can't imagine how hot-swapping could even work as long as the cellphone system is turned on. Maybe hot-swapping works in airplane mode?

According to this guy it's not good to do it: XDA post

Why do iPhones and iPods allow for this behavior?  You can use a small tool to remove the SIM card try and then replace the tray with a new SIM card.  The OS seems to pick up the new SIM and carry on with no problems, unlike most of my Android devices which require battery removal and hence a default restart/power-up.

I know I'm late to the party, but I just arrived here from google, so I thought I'd add my 2 cents. I just did this with an SII on accident, didn't destroy the sim card or the phone. I had to restart the phone, but it recognized the new one.

According to Verizon, at least, you should not install/remove the SIM with the battery in. Also, every picture I've seen of a SIM card has the text 'do not install with battery in phone' or similar.
I think that the SIM card standard wasn't built with hot-swap in mind. This may be one of those things that you can get away with, but if it wasn't made for hot-swapping, then it's likely that there's going to be trouble if you try it. The question is - does phone off and battery in count as hot swapping?
Edit - I had been thinking that one should remove the battery because I don't know if the SIM gets any standby power. But Eric's comment below reminds us that some phones have fixed batteries, and therefore it MUST be safe to insert/remove the SIM in at least these phones with the battery installed.
I'm still going to pull the battery whenever possible for doing SIM swaps, but since I only swap SIMs once every never, it's hardly a hardship for me.

With the RAZR, you have no choice but to leave the battery in. I've removed the micro SIM many times in RAZR/MAXX while testing apps and upgrades with no harm. That's not the same as saying it's a safe practice, but I haven't had any ill effects (yet).

@EricCloninger - great point. Logically it must be safe to remove/install the SIM from a phone with a fixed battery (presumably with phone turned off), because we do it all the time. I've edited my answer.

Also the phone will never recognize the new sim until it is rebooted, so you might as well turn it of before swapping sims.

For a lot of phones, the SIM slot is even located behind the battery to make it physically impossible to remove the SIM card with the battery in place. There is possibly a reason for this...

My ZTE Blade s6 has a setup procedure where the phone is turned on with no sim in then in step three it says insert sim card and the phone is on at this time, it then walks you through the rest of the setup, so I think phones with a removable sim tray and fixed battery are OK to do this.

Hot swapping with the airplane mode enabled did not work and did not harm my google nexus

See http://forum.xda-developers.com/showpost.php?p=1486893&postcount=4 for more info, enabling 'airplane mode' before is seemingly necessary.

Problem with downloading files from play market and websites
I have nexus 5 (android 4.4.2, TeamWin Recovery Project, root). Recently, problem with downloading files from play market and websites appeared.
I see infinite downloading in the play market. I see infinite work of the donwload manager process in the action bar, when I download some stuff from website (for example, when I try to download something from my HTTP local file server).
Sometimes I can solve my problem to restart smartphone, to clear data/cache play market app and download manager procces. But the problem occurs again.
Also I tried to boot into recovery, clear cache, fix permissions, and reboot. These actions have fixed my problem, but the problem appeared again.

What rom are you using? Just rooted stock rom?

@Zlatty, yes, I use just rooted stock rom.

I wonder if it is an issue with the storage. I had issues like this with a 4.2 rom on my Note II. I'll suggest an answer that might work below.

It is possible that the Play Store is having some issues writing on your phone. However, given that your phone is new(ish) and that there is nothing that's going on a SD card, it makes me think that the Play Store is getting confused.
Depending on what GAPPS package you installed, there could be a variety of tweaks that are done to the package. I would double check with goo.im or XDA to see hat GAPPS to install with your rom/device. Perhaps removing the Play Store, then installing a GAPPS with the right play store app would fix the problem.
Additionally, it could be that you have your runtime on ART instead of Dalvik and the Play Store is glitching up. To check your runtime, go to Settings -> Developer Options -> Select runtime.

really, I have ART runtime. However, I chose this runtime on day of purchase of the Nexus, and I had no problems for a while. Thanks for the advice. I'll try to reinstall GAPPS.

SMS shows up in alert box. Why?
I have recently been using a particular 2-step authentication system and there is something odd about the SMS messages I am sent which I have never seen before.
When I receive and SMS from the system, there is no notification, and the message does not immediately show up in my hangouts inbox. Instead, the SMS pops up as an alert dialog over whatever I am doing with the phone at the time with the option to "Cancel" or "Save". If I tap "Save", the message is then stored in hangouts and I get a notification.
What I would like to know is why this happens. Is there a (rarely used) part of the SMS specification which provides this functionality? Is this 2-step auth system making use of that? Perhaps setting a flag in the header or something?
EDIT
I am running Android 5.0.2 and the default SMS app is Google Hangouts. I'd like to be clear though that this only occurs when receiving texts for this particular 2-step authentication process. All other messages are received as normal.

Sure it's an "alert box" – and not "headup notification"? Which Android version is your device on?

@Izzy maybe dialog box is a better word for it. Grey box in the centre of the screen. Displays the SMS content + "Cancel" and "Save" buttons below.

What happens when you press "cancel"? Also: what's your current default SMS app? Still open: Android version?

What is the name/version of your "sms" related application? This is likely the expected behavior of some app that interceps your SMS messages.

@Izzy oh, I forgot sorry. Android 5.0.2. Cancel just removes the dialog. Nothing more. Default SMS App is Hangouts.

Thanks! And I assume you've verified that Hangouts is still the default SMS app (because AFAIK only the default app is capable of receiving SMS – which would make your issue looking really strange). Another suggestion: Could you please [edit] your question and integrate the details collected in the comments, and then we do a little cleanup?

@Bonatti default SMS app is Hangouts.

Is this 2-step auth system making use of that?

Could be, in order to be sure, we need details on the application. Open the config tool, check the application that is creating the confirmation box, and check if that app has access to read your SMS.

Perhaps setting a flag in the header or something?

There are no "headers" in the sms PDU. They can either filter by "sending number" (the number from the SMS sender), or by filtering words inside the message. Check if the received message always starts with something such as "X company says..."

What is going on?

Again, this is speculation, since we saw no details on your problem. But...
It is possible to intercept SMS messages, read then, check for a condition, then use an ordered broadcast to open an application, and given a specific condition, become the default sms app, stop the continuation of sms delivery intents, and erase the message, then stop being the default app, or just let it fly onwards...

which apps are these!! we stay in brazil
I want to know the name of these apps .. i want to track my sister.. she doesnt let me touch her phone.. i just want to know the name of these apps....

i want to know the name of the apps.. the 3 notifications indicates the app..   i searched it but i couldnt find.. i hope if anybody can tell me.. we stay in brazil.. so the app might be common to brazilian

What is the Phone model?

The first looks like a completed download. The second is the voicemail icon, just the regular phone app. (Note that I'm not sure about the first one)

Can you support your answer with links to apps or icons with context explaining what you mentioned briefly?

The completed download, I took a guess as it is the most likely thing that would result in a tick. Most downloads, whether using chrome or some other 3rd party browser/app (like es file explorer) result in such a tick. The voicemail one - that is a universal symbol for voicemail! Just google "voicemail" and all the images are of that. Even landline telephones have that symbol.

I suspect you are wrong on the first count, and probably correct on the 2nd. Note: Chrome or Firefox indicate completed downloads with a fully-shaded down-pointing arrow with a horizontal bar below it.

@TamoghnaChowdhury I know. But I apps like es file explorer display such icons for completed downloads.

Problem With Phone Camera
When I take a picture it says couldn't find file and when someone sends a picture on WhatsApp it says file doesn't exist on the sd card. I have to turn the phone off and back on and they have to send it again. I have ESfile explorer. I know my cousin moved some stuff. I don't know what to do please help.
I have the LG g stylo Android version 5.1.1. I have tried changing where my picture saves and erase es file explorer but nothing.

Your question is missing some pretty important parts.

@SarpSTA: but if you don't tell OP what they're missing they might not come to know. If you need something, try to say it clearly in your first attempt, since otherwise 4 comments will be used just to take care of only your clarification and that would be a highly inefficient way for seeking clarification. :)

The important parts is the punctuation. Stream of consciousness is not the way to go here. Run-on Big Block of Text (BBoT) helps nobody, especially yourself, since it encourages others to ignore the question.

This is a pretty vague question (if you could modify to explain other details it would help, such as locations where images are working, how long after reboot does it stop working, etc) but it just sounds like an issue with Androids tmp folder used for "caching" images for quicker viewing.
This can be caused by deleting tmp, or by system IO errors on the dom, or a load of other possibilities. Without a more precise question I suggest you try reinstalling affected apps. If that doesn't work try backing up your important stuff (images, whatsapp, etc), wiping your phone, then restoring. If you have to do this DONT use system backup, that also points to the tmp IO handlers, which is probably what you're having an issue with.
Hope this helps

How to root Lenovo A1000 Smartphone?
I tried Kingo Root and Root Genius and some other software but finally failed to root this phone. My phone is Lenovo A1000.

Welcome to Android Enthusiasts! We will need more information to give good recommendations here. Please [edit] your question and include at least: The Android version it is running.

For users who flagged this as "Unclear what you're asking": assume Android 5.0 if OP doesn't clarify since I don't think Lenovo pushed any update beyond that version.

I have Android 5.0 and i can't Root this Phone.

To root a Lenovo A1000 smartphone (Android 5.0), go to kingroot.net and follow their directions to download, install, and run KingRoot.  I downloaded the Android .apk to my Linux laptop and copied it to the phone via adb, but I'm sure downloading directly to the phone (they provide a QR code) would also work.
By the way, add SuperSU to the list of ones that do not work on this phone.

Google apps settings deleted
I just deleted the Google apps settings by mistake (from Applications -> Google Apps -> clear data). So, my HTC Magic is not connecting to the Google server anymore. How can I input the dates I've deleted? Can it be reinstalled?

I'm not sure about HTC, but you can probably configure your Google account in Settings > Accounts.

How do one know which folder is created by which Android apps?
From my understanding, a majority of Android apps may have created some folders on either local storage or the SD Card.
So, how do I know which folders belong to which apps? (I know that some apps have settings that show you which folder that they have created but are there any solutions where one can easily find all the folder corresponding to their apps in a list similar like the one shown below?)

====================================
| Apps Name |   Folder             |
====================================
| ABB       | \sdcard\actionbb     |
| ZZX       | \sdcard\zoneX        |
|           | \local\zoneXconf     |
====================================

This is because, sometimes, when one un-installs an app, the un-installation does not remove these folders.

If you open a file as Context.MODE_PRIVATE, then the file is created in /data/data/app_packagename and is only accessible to your app. You can see the permission and owner of these files in command line.
adb shell ls -al

drwxr-x--x    1 app_28   app_28        2048 Dec  6  2011 com.android.mms

But files in sdcard is public to all user, so you cannot find out which folder belong to which app.

Files saved to the external storage are world-readable and can be
  modified by the user when they enable USB mass storage to transfer
  files on a computer.

See this link for details.

Though, some apps store their contents on SD card in a directory similar to that on internal storage, something like /mnt/sdcard/data/com.myapp, in which case you can check this package name (here: com.myapp) with the playstore's web frontend, adding it after the "id=" parameter. Unfortunately, these kind of exceptions are few...

So, there is no other way to check which folder inside the sdcard that belong to which apps unless one check the settings inside the apps and also the apps have information that tell user where they store their files into which folder in the SDcard. However, I still hope that there are such application that can provide the list. (or maybe google play can tell us what folders are created when install the apps, just like what it did to the permission - it tell the user what permission the apps are asking for)

What about human heuristic based on file/folder creation/modification time? I'm just reasoning, I didn't tried it yet. But if I installed an app yesterday, and it created a folder on SD Card, then the folder should have a creation time that reflects that. Looking for files in already existent folders would be a pain, but should be still possible.

Galaxy S2 not charging
Galaxy S2 not charging tried usb and wall charger, initially I had this problem I removed and put the battery back it and it then began to charge however on next charge it stopped in mid charge ( normally leave phone off when charging).. now its just a lump of black plastic.
I tried removing the battery while plugged in , then powering on immediately after putting the battery back in , cleaning the port, even reboot does not work ...any suggestions...my guess I need a new battery although it is less than 12 months.

2 possible causes:

Faulty battery
USB port defect

Both of these are hardware problems. To be frank, battery charging problems seldom have to do with software defects, so the best thing is to send it to the nearest Samsung service centre and get it fixed, or maybe even a replacement.

If you didn't change anything on your phone and it's still under warranty (you said less than 12 months), the easiest solution would be to take your phone to a Samsung service center. They might change your battery for free.

Unfortunately, contacts has stopped Galaxy note 1 stock firmware
I'm running stock android version - 4.0.4 with baseband N7000DDLR1.
Received a minor update today in India(14.5MB) which said a performance update.
Everything worked fine after the update. However, my contacts and phone applications have stopped working. When I tried opening any of these apps I get "Unfortunately, contacts has stopped".
I have cleared the cache/data of contacts, contacts storage, phone. I even did a factory reset twice; removed the memory card and tried the same. Problem persists.
PS. I have never rooted / installed custom firmware.
Kindly help.

Came here from a Google search and thought that I would add that I have the same issue with an LG Optimus F3, Android version 4.1.2, software version P65910b. Factory reset does not fix the issue. I have submitted a warranty replacement to get a new phone; hopefully the new one is not affected.

It was some problem related to the motherboard. Samsung guys replaced the board.

This is a firmware issue, and needs to be addressed by the manufacturer.
If you have done a factory reset, then you should contact the manufacturer and tell them that after the latest upgrade, the contact and phone app no longer work.
They should release a new upgrade to fix this issue.

gave it to samsung, and they gave it back - the phone wasn't switching on at all! I have given it again and I hope it isn't a major issue.

App that optimizes images to set as lockscreen?
How can I resize any image I have to 720 x 1280 resolution to set it as a lockscreen for my Xperia T? I tried Wallpaper Wizardrii but for some reason I cannot get the app to enlarge small pictures to entirely fit the screen.
I had an Apple phone they there was an app called "lockscreen" that automatically stretched/resized any image to match the screen resolution without any empty vertical or horizontal bars.
Are there any equivalent solutions for Android?

Please note that questions of the type Is there an app for X are off topic here (see our [FAQ] for details).

I have edited the question to be more about a problem to be solved than about an app to be found.

you can try the Go Locker.....

Would you mind to add a little more information, e.g. at least a link and a short description?

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference.  Link-only answers can become invalid if the linked page changes.

Im sorry, it-s just im new here so i dunno how. and this is the first question that i've answered, well Go locker is an application for android. But I reviewed your question, you said you need an app. automatically resizes any image, you can try to search in google play or play store the app.. 'Photo Resizer' or 'Image shrink'. I hope it can help. sorry

Hey no problem, at all. There's the edit button below your answer to do this. This site is somewhat like a wiki. So it's appreciated to edit, btw. So just hit it and add e.g. the link to the play store + maybe the short description, would be fine.

Searching and filtering Android Market app reviews
There seems to be no way of filtering or searching the app reviews in Android Market. This is a problem because it's usually the low-scored reviews that are most useful - they give an idea about what people are finding as disadvantages, so I can decide whether or not those are relevant to me or not.
Is there some way around this restriction? Does Google provide the review data in some way that could be searched, for example all reviews on one big page?

This would be nice, much like Amazon.

These days, the Google Play Store (renamed Android Marketplace) does in fact have review filtering based on the rating.
Just click on "User Reviews" and the "5 stars", "4 stars" titles for the bar graphic are now clickable, and clicking them displays only reviews with that rating.
Thanks, Google!

The comments are not searchable from the market app, nor are they searchable from the site, but you can search google using site:market.android.com my search terms here and it does include the comments when searching.
All the comments are also visible on the market site under the "user comments" tab for the application.

However, the site-wide google search isn't limited to a particular app. And the comments on the market web site are only displayed 10 at a time, so they're not very searchable.

Discrepancy between sizes of apps listed in Play Store vs. actual installed app size
The Play Store lists the size of all apps available in their store.  When a user downloads and installs apps, the actual sizes reported by Android are often larger than the sizes listed by the Play Store.
Of importance, this discrepancy occurs before applications are even run for the first time.
What is the reason for the discrepancy?

Apk and zip files are essentially the same, compressed. Before the system can use the file it needs to decompressed. So the file is one size when downloaded and another size when installed.
Also note sometimes when apk's are installed, after being opened some data may need to be downloaded. So file size file will increase again.
Differences in size are noticeable when comparing between Android markets, one shows one size and play store shows completely different size.

Thank you so much.  Silly Google... it's obviously important to know how big the app will be once installed... too bad Google omits this information from their Google Play Store.

You mentioned "sometimes when apk's are installed, some data may need to be downloaded".  Is this correct?  Can apps download data just by being installed (and not opened)?

I meant after opening, my answer has been edited to reflect that. But no an app shouldn't be able to download data before opening it the first time. Now first time can also mean after a reboot, so some data can be downloaded then if internet connection is present or as soon as one is available.

Thanks!  I assume in your comment above that you meant "But no app SHOULD be able to download data before opening it the first time" instead of "But no app SHOULDN'T be able..."?

@RockPaperLizard  Lol. I was in a rush, but yes that's what I meant "...no app SHOULD be..."

No problem.  Thanks.  BTW, you answer inspired me to compose a related question: http://android.stackexchange.com/questions/107258/can-an-app-run-code-if-you-dont-open-it

Glad I got you thinking! :) I'll check out that question.

The Google play store, and other app stores, only list the main application (APK) size, not the total app size, which includes the OBB (Opaque Binary Blob) expansion files. OBBs are the extra files that an app downloads to run. There should be no difference in file size before the extra files are downloaded.
From the Play Store Developers section:

The maximum supported size for a single APK is 50MB. If you need to store additional assets (images, for example), you can upload expansion files.
If your app needs more than 50MB of memory, you can use expansion files to store additional APK assets. You can store two expansion files per application. Each expansion file can be up to 2GB in size.
Expansion files are hosted at no additional cost. When possible, Google Play will download expansion files when apps are installed or updated. In some cases, your app will need to download its expansion files.
When you use expansion files, one file is the main file and the other is an optional patch file. Optional patch files are usually used for small updates to the main file.

OBB files use the same compression as APK files do, which is a standard zip compression. APK and OBB files are kept compressed in the file system, and files inside are decompressed into memory as needed, on the fly. So no, the compressed size, which is the space occupied on the device by the APK, is not different from what the Play Store should list.
Finally, the Play store allows multiple APKs per app listing. This is because some bigger apps (mainly games) need to target different resources (graphics engine, display size/resolution, etc.) and they cannot fit that inside of a single APK (due to the size limitation). If you look at the same Play Store page on different device types, you will likely see a different app size listed.

This brings valuable new information to the answers here. Can you expand on your answer at all?

@rockpaperlizard spock what else is there to expand on?

+1 for being the first person to get it. :-)  Some more detail about what is actually downloading the OBB files (the app or the Play Store?), why you refer to them as "expansion files", and whether general compression (as mentioned in the other answers) is an additional factor.

@RockPaperLizard done.

Thanks! I've made a few edits just to clarify, please correct my edits if I made any mistakes.  Based on the great info you provided, I created this question: http://android.stackexchange.com/questions/108931/how-often-does-android-have-to-decompress-an-apps-apk-and-obb-files

The Google Play Store no longer lists sizes when you're logged in with an account that has multiple devices attached.
The maximum size for an APK has gone up to 100MB since 28 September 2015 (ref: Android Developers Official Blog)
Because of the decompression and different versions and devices, the install size of an app depends on the device - "Varies with device". Only for some apps, you can see how big they are by visiting the play store without logging in.

I'd love to know if there are any indicators to say 'approximately' how big an app is (<5, 10, 10-50, <50, 50-100 etc). Thanks @Andrew for the edit (:

Because Play Store shows download size, and download file (probably apk) is compressed. When you install app, apk is decompressed and larger.

How to calibrate a new Nexus 5 battery that's higher capacity than original?
Just got a KBTEL battery that's 3800 mAh compared to the original 2300 mAh nexus battery. I charged it dead overnight, and now its been running for more than 7 hours and the capacity shows below 5% for an hour now but its not dying. How do i get the battery meter to show the actual range? The system still detects a 2300 mAh battery.

Not a dupe, but general method to calibrate the battery on Android

Battery Calibration thread on XDA forums. Download from the Play Store.

Description°
Requirements: Android 2.1+ | Root permissions
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.

°copied from https://play.google.com/store/apps/details?id=com.nema.batterycalibration

Deleting the batterystats.bin does not help calibrate the battery. that was a myth and misconception, which was debunked by Google Android Engineer

@Ryan - that might be so, but it did straighten out the mis-calibration problem that I was having. Reboots did help, nor did cache/dalvik wipings. I have wiped battery stats from recovery as well, with excellent results. Go figure. :)

@Ryan - I read through the debunk link, nice points, but she doesn't provide any reference/fact/resource to prove her statement other than her own admission. After that the comments seem to start to drift.

The fact is she is an engineer on Android, the comments are from people that do not work on Android. This information is also 2 years old. Just search for "batterystats.bin" you will see the same information. The batterystats info is cleared when you unplug from a full charge. What you experienced is the placebo effect.

I don't have root permission. Isn't there a simple solution? But I'm on the new battery for the 2nd day today, and now it seems to be working right. I see more than 12 hours battery life expected which is what i expected from the new battery.

Well, actually it does not calibrate the battery. As the article say, the file is deleted every time you charge to 100%. That's the way to recalibrate your phone! Every time you go to 0% to 100% the battery calibrates.

How will I know the signal strength of my smartphone's 3g?
How will I determine the signal strength of my smartphone's 3G whether strong or weak?

check  right angled triangle symbols, to the left of H with arrows. if they are completely white colored , signal is strong, else it degrades to lower.

Try Signal level notification app.

The title seems on-topic but the body appears to be off-topic. It is Android independent because signal strength is not Android specific thing.

To see the signal strength:

Go to Settings → About phone → Status.
For dual sim phones: go to Settings → About phone → Status → SIM status.

How can I get the correct mapping for my bluetooth keyboard?
I have a Galaxy Tab 10.1 running Android 5.1, and a Buffalo BSKBB22 bluetooth keyboard.
It connects fine, and I can type with it, but the keyboard mapping is off. The keyboard itself has a Japanese key mapping, but it seems I can only select from various western and European key mappings in the settings on my tablet device.
Is there a way I can get the correct key mapping for my bluetooth keyboard?

You can try this paid app from play store External Keyboard Helper Pro or Tincore keymapper

@Lucky, thanks for the suggestion. Unfortunately, External Keyboard Helper Pro does not include a Japanese keymapping. As for Tincore... I can barely understand it. It's not very clear on what exactly it does or how.

Shutdown animation sound
I have an issue, when I shutdown the phone, it gives a custom sound. I want to remove it. The phone is LG G3 (Rooted).
I tried to delete the sound using root explorer.

To mute them, Simply do the Following :
In System > Sound and Display > System volume you can set it, unfortunately the power on/off sound is also tied to the touch feedback sound.
You can also use Silent Boot.

Note:Disable annoying startup sounds! Silent Boot mutes your phone on
  shutdown to keep it silent on boot and restores previous volume
  settings after startup is complete. Please note: This workaround does
  not apply to all phones

Lastly, Here the one which I followed :
1) First off all download the Root browser from play store.
2) Open it, the app will ask you to install some additional data, don’t cancel it – otherwise the app may not work properly.
3) Now when the additional download complete, search for the System folder & open it, followed by Media or sound folder.

4) Here you will get two  files namely PowerOn.mp3 & PowerOff.mp3
5) So long press the PowerON.mp3 file > choose Rename > rename the file to PowerON.mp3.bak. Same with the PowerOff.mp3 file, rename it to PowerOff.mp3.bak.
That’s it, now reboot your phone and there should be no shut down and start up sound.
So if you’re happy with permanently turning off the sound, then your steps end here. You can leave this guide now. But if you want to replace the default android boot sound with any mild music then follow this steps.
6) Now download the soft sound which you would like to set as boot sound.
7) Copy that to System / Media folder & rename it to PowerON.mp3 & power Off.mp3
8) Now long press on new sound file, select permission from popup.
9) Tick all the boxes that appears after selecting permission, then press OK
10) Now every time your reboot your phone you will be welcomed with your new boot sound.
Note :- Make sure to keep the new boot sound file length with in 10 sec. Otherwise you will feel double irritating.

Change the screen resolution to 1024x768 on Samsung Galaxy S3
I'm trying to download a mobile credit card app and it requires the resolution be this. How can I change my screen resolution to 1024x768 on a Samsung Galaxy S3?

Hi and welcome! Which mobile credit card app are you trying to download? From which website?

Which Android version are you running? Is the device rooted?

Ditto on Android version as per Firelord pointing out. You should always specify what Android version your are running!

You may need to be rooted. You will need to install terminal emulator. You may also need to install some type of script management tool.
in terminal run:
to display current window manager settings run
wm size && wm density

Output ,for my device, yours will vary,
Physical size: 800x1280
Physical density: 180

To set to required size , [landscape]
wm size 768x1024
stop && start

NOTE: You WILL need to repeat the process to set your screen back to normal so, keep note of your original screen size. This is why i suggest a script management tool.
To return screen to original size; [my device, landscape]
wm size 800x1280
stop && start

You may need to reset your lockscreen wallpaper, mine doesn't seem to restore to proper size when i perform these commands.

Given that OP hasn't mentioned which Android device is installed would you mind mentioning am display-size as well? wm was introduced only in JB 4.3 and it doesn't need root access when used with adb shell but am does. But I get your point why you wrote "may need root access".

@Firelord , i assume the version running is JB as the S3 released bothe ICS and JB. As I only own KK->LP devices wm is my option. If and when the user clarifies which Android version, then they will accept the given answer or request additional information.

@Firelord , isn't it a horror that devices are still running GB? xD

Why does the youtube offline videos get expired
Weird behavior of offline videos. I had downloaded a lot videos from office for offline viewing at home. But when i went home they were showing expired and when i clicked on them it showed connect to internet to update. So i went online but even then it was showing connect to update, but after long hours of searching over the internet i couldn't find any solutions. So i first removed them from offline and re-downloaded them.
That was okay, but the same thing happened today hence i am frustrated. My questions are like this:
1)Why are they getting expired
2)Solution for the above question.
Screenshot:

Screenshot - (click to enlarge)

This is related to YouTube Offline Videos deleted/removed

no i tried the above link, but its a different issue. I will add a screenshot..

I guess you can re-download the videos by clicking the 3dots near the expired video.

Ya i have mentioned that also, that if i click on that it will show connect to internet and even if i connect it will repeatedly show the same. So i finally had to remove it from my offline and re-download it again.

Apparently YouTube videos downloaded for offline viewing get expired after a certain amount of time. I haven't heard anything official about though.
The downloaded  videos are stored in the internal storage but they are saved as .exo file format which only the YouTube app can open (you can't play them with any other media player app)
The best advice I can give you is to use a YouTube downloader like Tube mate to download the videos.

Ya but why arent they trying to fix this and i have not uninstalled youtube.. And reinstalled, its like it remains there and ur right apparently they get expired

I don't think it's a bug, the devs probably intended to make it like this. Try using TubeMate app instead

It seems that YouTube Offline feature is expected to work that way, in specific regions/countries.
In India, those offline videos are not removed at all(unless YOU remove them or uninstall updates of YouTube app or if you connect the device to internet even once during the 48-hour window, the YouTube app will be able to verify the status and will refresh the 48-hour deadline.)
Read more at:  Here is the link which confirm this.
But in some specific regions/countries videos are removed after 48-hr expiry time.
Below is the relevant quote from article in http://www.engadget.com/

Anything you save will be accessible for 48 hours in the offline
  section on the left-hand sliding menu.

Check this link for more details:
Hence, it is not a bug or issue but the Business model of YouTube.
You may or may not agree with it but that is the present situation.

Yes it is based on location/country too. But I don't agree that it will never expire. In India I still notice some videos expire after a specific time period. Reason: The video uploader can set the expiry days so once the time period exceeds you need to redownload the video by connecting to internet. In fact it was available to me for more than 48 hours. :)

@Lucky yes you are right. I am in India. Many videos are suddenly shown in my Asus Zenfone 2 as expired. They expire in India also.

Just change the date of your device and disconnec it frm internet .       Change date to the one when downloaded

would like to try it once

But what about the sync on my phone would behave.. Can i correct it back and will that effect the youtube vids again

@DJphy yes you have put a very valid point. It's too risky to change date. So, it's better not to tamper with it unless you are sure what all that can result.

Here I Cameroon it is 29 days. But I've got to connect only to a wifi network to get it refreshed.
Clearing cache never cause the videos to expired. Rather what I realize is that during download if you forcestop YouTube app or you have a shut down, you tube won't care whether you were downloading a 4GB video and you were at 99%..... Trust me.. You may have to start all over again.... That's how it works with me

Offline videos expires when you clear the cache of YouTube app.
If you dont clear, then all videos will not expire

Downloaded videos from YouTube expire after a 48-hour period. Clearing the cache might invalidate the period and cause the videos t expire immediately. More probably, since the videos themselves are considered cached, clearing the cache will delete them. Your answer is blatantly incorrect.

Does data reset wipe batterystatus.bin?
Does data reset delete batterystats.bin?
Location of batterystats.bin file is /data/system/batterystats.bin.
Note: NVRAM also remains in data partition but data reset does not wipe IMEI.
Can I calibrate the battery without rooting the new custom ROM?

What is a "data reset"? And what has the batterystats.bin to do with battery calibration (it only holds usage stats of apps)? To calibrate your battery, simply run it down to below 20% (but not below 5% if it can be avoided), and then charge it up to 100% in a single run without disconnect. Done.

If you wipe data/factory reset in ClockWorkMod or TWRP recovery, then it should remove it. The stock recovery probably will wipe it.
In general, to access recovery, turn off your phone and pull the battery (certain phones have a mode where they "hibernate" instead of powering off...)
Hold the volume up button and then hold the power button. When the phone vibrates release the power button but keep holding volume up.
Note: Factory resetting in Android may not remove this file. A research project by Cambridge University showed that there is a security flaw in some Android devices where not all the files are wiped...
This is because the recovery formats the data partition, so it will certainly be deleted.

Motorola Defy + Keeps Rebooting
I bought another Defy + for my daughter. I also have one which is fine.
Hers keeps shutting down and rebooting, especially when it's away from the WiFi. It also has the latest system update. We tried switching batteries, but hers kept rebooting so it's not a battery issue.
Any help out there?

Not enough data to give a thorough answer. Could be a misbehaving app, or something screwed up. Did you try it the hard way (factory reset)?

Its a faulty phone. Take it back and get a new one.
But you can turn off mobile data and it will stop rebooting.
or search google for "Motorola Defy+ Rebooting" for other opinons

Installing HD Games on HTC Desire SV,low memory
I have an HTC Desire SV, which has almost the same specs as Desire X. The problem is I'm unable to install HD games, since the phone storage has only 800MB space.
I have gone to Settings > Apps and checked for the option to move to SD card but there are only 2 options available move to phone and move to internal.
I cannot play games like Max Payne; it has cache files around 2GB. Since the cache is too big for the phone memory, I cannot install it.
How can I install games like Max Payne?

Short answer:
Thing is: you can't, obviously, as you don't have enough internal storage.
TL;DR
If your device is rooted, however, there are ways to work around this storage problem. You can fool your device by linking/mounting a partition on your SD card to be used as "fake internal memory". But while this would work-around the underlying issue (not enough storage), the Playstore still would refuse to let you install those apps, as your "official phone specs" have not been changed. If you could get hold of the .apk, however, you might be able to side-load (manually install) it. Also, having root, you could manipulate the system file responsible for this (build.spec?), fooling the playstore into thinking your device would be a Desire X (or whatever you chose).
So you see there might be work-arounds, but they are not easy to apply. Without rooting your device (and thus most likely voiding your warranty if you're living outside the EU), it simply is impossible AFAIK.

I have the .apk file,is there a way to install it manually?The problems is, i don't care where the apk is installed what i care is about the data files which are around 1.2 gb

Sure: Simply put it on your SD card, and tap it from a file explorer. That should launch the installer. Make sure you've configured your device to allow "unknown sources" (i.e. sources other than the playstore). Still, your storage will be too low unless you root and "switch things around". But you can try ;)

You see i can install the app,the problems is with the cache/data files.i cannot put in the external card,it does not work

As I wrote: That part is only solvable on rooted devices, sorry.

ok,Thanks will check with HTC if there is a workaround without rooting as rooting voids my warranty

I doubt there will be any (except for buying a new device) -- but please keep us updated! Would not be the first time I get surprised :)

Internet Apps are not working but browser works just fine and i am able to access websites
I have a rooted AT&T HTC inspire 4G handset, i am not able to use any internet apps but i am able to use the in build browsers to access internet over a WiFi.
I tried creating  hotspot and share that internet with this HTC phone and everything worked just fine all the Apps and internet.
Please help me with this, I did tried syncing background data, and WiFi proxy setting, but No luck yet.

We've already got this questions a couple of times here. Please check: connection issues - Apps can't connect to internet, rooting - I rooted my phone. Now apps cannot connect to the internet but browsers work fine, and also follow the links of your tags (e.g. "internet") for further possible solutions. The "Related" section of this page also might hold something useful.

Amrit did you get a solution for the problem you raised?

DELETE HOSTS FILE

For advanced users only and for rooted Android devices.

Open File Manager App.
Browse to /system/etc.
Delete hosts.txt file

That's a stumper - have you tried calling up your carrier and making sure that it's not an issue with them?
Have you installed any permissions privacy management apps?  They might be blocking internet connectivity by default.
Failing that, the only suggestion I would be able to make is to do a full factory reset... not very appealing, I know.

Thanks Logos for the quick response, well actually its my office phone,I have rooted this phone and the only other apps i see are BusyBox installer,Teeter & Superuser. The weird thing is that with my office Wifi i am able to access internet not apps,

Solution which worked for me is by installing the configuration settings. Call up the customer care and ask them send you the configuration settings. Since you reset your phone old configuration settings would have been erased. Once you install the configuration settings you will be able to access internet for all the apps.

Quote OP's comment:

It could be because your office WiFi may be blocking that apps. (Eg: Facebook)

Autocorrect is not working for Huawei Ascend G600 (U8950N)
I just bought a new Huawei (running Ice Cream Sandwich). When I use the keyboard (both the Android and Huawei IME), the photo does not recognise any common words in English, and so it underlines them all as errors. It recognises the names from my contacts, but not the main dictionary.
I could, over time, add the whole English language to my personalized words list, but I would rather not!
Any suggestions for the problem?

Have you checked whether a local dictionary is installed for your language? some keyboards require this for that issue. Besides: How shall a photo recognize words? Is that a typo in your question, or did I miss something?

I have installed Go Keyboard and deactivated the phone's default autocorrect and spell checker. This seems to have solved the autocorrect dictionary problem, and I'm happy. Seems to be an issue with the factory software from Huawei...maybe. Dunno.

I have this same issue. Would you mind outlining your steps to fully correcting the problem? Would be very helpful. I also saw a suggestion to use JellyBean Keyboard. Something about a missing dictionary

When I tap on an explicit RSS link shown in a web page, I have the opportunity to complete the action using RSSDemon. But no such thing happens for hidden RSS links, whose presence is revealed via the RSS icon in the address bar. When I tap on that, I can only add the feed to Google reader. Then I have to import the link from Google reader. How can this be bypassed? I want to go straight to my preferred RSS app.

Maybe you can use catch-all handlers like Copy to clipboard or Andmade Share (replaces stock share target menu and adds multi sharing, e.g. to send a file via BT and GDrive in one step). Let me know if it works!

I rooted my phone, but I never flashed the ROM and I never flashed the recovery, then I unrooted it. Can you tell its been rooted?
I am using a Samsung Galaxy Pocket (GT-S5300) which has Android Gingerbread 2.3.6.
I rooted the phone by applying update.zip through the recovery console.
I installed titanium backup free, and ROM manager free, but quickly uninstalled them after I saw that I did not really need them on this phone.
I never installed clockwork recovery, i never flashed anything.
I then unrooted the phone by repeating the steps I did to root, using the unroot.zip (renaming first to update.zip)
That worked and Superuser app was removed after reboot.
Now what I want to know is....can Samsung tell my phone has been rooted?
If so, what can I do to remove any trace of it?
Thank you. I know this question has been asked before and answered but I could not find an answer which dealt specifically with my situation where nothing was ever flashed.

The short answer is yes. You should make sure your bootloader is locked by executing fastboot oem lock in your command line while your device is in fastboot (Home + Power + Volume+ for your specific device). Once your bootloader is locked it will be as if you never rooted your device. Once this is all done, you will regain your warranty which would otherwise be voided if you had left the bootloader unlocked.

From recovery mode you then go into fast boot. By command line I meant the terminal on your computer.

Why does my google maps keeps on crashing even though i'm not using it at all?
So, I'm just using my apps. Then sometimes it freezes for a while, and a notice will pop-up and say "Unfortunately, maps has stopped." even though I'm not using it.
What do I have to do?
Samsung Galaxy S 3

what apps have you been using?

It could be that you have enable something like Google Latitude tracking, which goes via the Maps app on your phone. Maybe have a look at the settings in your Maps app to see if there is nothing enabled that works in the background, and prevents the application from stopping.
Maybe you have used the application some time before that error? Because Android will not immediately close applications, so it could be that the Maps app is still open from a couple of hours ago.
Maybe some other application is trying to open the Maps application for you? If you for example click on an address or something like that, most apps will try to open your default Maps application. So maybe you have opened/connected to the Maps app without really knowing?

Trying to invoke Skype from contacts gives me an "Application not found"
Samsung Galaxy S3 Mini, Android 4.1.1.
I have installed Skype and it works as expected. In my "normal" contacts list, i.e. the phone contacts, not the Skype contacts, I have entered the Skype data for some of my contacts under the "Skype" section. However, when I click on a contact and on their Skype-section I would expect Skype to start, but all I get is a message saying "Application not found". Invoking Google Talk for instance (on the same contact) works as expected, it's just Skype that's not beeing found.

Try going into settings -> applications -> skype and clearing the launch by default setting.

Default settings for Skype are grayed out, so it seems there are no default settings associated with Skype...

Having same issue, seems like instant messenger records in Google contacts are treated as informational note and aren't actually treated as info about accounts.
The workaround is to explicitly combine contact entry with Skype entry in phone - that makes Skype actions (chat, call, video call) available when clicking contact's photo in contact list.
PS weirdly for contacts that have Skype login saved in Google contact I see Skype option show up under Google Talk action. Gives same "not found" message.

Samsung s3 Unlock
I bought a Samsung phone, on the T-Mobile carrier in the US. I went to India last week, and got my unlock code from T-Mobile. My India-Vodafone SIM is working fine, except for the internet. I have called customer care, and have changed all the settings, but it doesn't work.
How can I make internet work?

If the SIM card works, and you can get a network signal, then the deice is unlocked and it is a different error that is stopping internet from working.
It could be due to a number of reasons that internet isn't working, I am going to list them:
Invalid/Wrong APN's
APN (Access Point Names) allow your device to connect to mobile internet. You nust ensure you have the correct ones installed for your network.
Device not compatible with internet system
IIRC, the T-Mobile US network uses a different system... It could be that this system isn't compatible with your Indian network for internet access.
Other than the above, I cannot think of any reason internet wouldn't work when mobile network does. Make sure your network is letting you use the internet (no bars, you have internet with your plan) - otherwise, I do not know.

I agree with Liam. The problem is most likely that the T-Mobile phones use different bands than just about any other carrier worldwide for their HSPA network. If your carrier has EDGE, you should be able to connect to that, as it should be the same bands.

To put it in other words: Try fixing your device to use 2G (or GSM, whatever it is called in your menu) instead of letting it decide automatically, make sure not to use UMTS/CDMA/HSDPA/LTE/... This for sure is slower -- but it might at least work. As a side-effect, you battery will even last longer, as 2G uses much less power than 3G or 4G.

if your phone is working after inserting the different sim card and working fine your phone is unlocked, and there is no issue in phone unlock, the most likely reason for not working the internet is that your phone APN setting is not configured properly, you must have to configure the correct APN setting for that network,

application cannot be installed in the default install location?
I have an Android Galaxy S1, and have been getting the error "application cannot be installed in the default install location". I am aware that this is a common issue. So I Googled it, and almost everyone is saying to move your apps to the SD card or delete unused games.
There's only one problem. My phone won't let me move apps into the SD card, and I have 1.3GB of free app space. While I can download some apps, the more important ones won't download.
Anyone have any fixes to this?

You cannot! Some require to be on internal storage, read non-moveable to external storage for the app to work, widgets is one example.

So there's no way to fix the "application cannot be installed in the default install location?" error without moving apps to SDCard, is what you're saying?

It depends on apps that are required to be on internal storage, facebook, google mail, play store, to name but a few are ones that are on internal storage only, i.e. default install location! :)

I am facing the same problem, what i did is uninstall some unused app & then reboot my device. Now, after it my device is working charm... :)

I don't think this really has anything to do with any settings.
I encountered this yesterday. All I did was restart my phone and the app installed fine afterwards.

Ran into same issue, removed some really large apps off the phone and it installed fine. Guess it was a space issue.

Developers can define the App Install Location in their app's Manifest file. As you stated you cannot move apps to your SDCard, this might be the clue: Apps having their install location set to the internal storage will be able to install, while those defined for external storage (i.e. SDCard) are failing for the very same reason: They cannot be moved to the SDCard.
So your real problem is: Why can't you move apps to the SDCard? To find an answer to this, it would also be helpful to know your Android version. I'd suggest making this a separate question linking here, and giving some more details on your device and Android version there.

This is what worked for me.
If the settings-> memory is set to SD card then change it to Internal, or visa versa.
Unmount the SD card.
Install/update

I have android 4.1.1 what I did to fix the issue about installing to default install location.... Go to settings ....then to storage....then the preferred install location....then select let the system decide
That's it . U can always change it back to sd card when u finish updating the apps with the issue

Cannot access internal memory due to cyanogenmod encryption, how can i decrypt the device?
I have ran into a small problem with my android tablet, it is a samsung galaxy tab 8.9 p7310
About a year ago i rooted it and installed CWM + CyanogenMod 9; i also encrypted the tablet. When i go under security the encrypted button is grey and i cannot click it, when i go to disable pin/password lock to none i cannot click on them and it says disabled by admin,encryption, credentials...
I cannot update my ROM because the SDCARD is encrypted and recovery cannot mount it so i am looking into alternatives, how can i format the internal memory in such a way as to reload the ROM; i don't care about the data stored on the device.
I have looked into nvflash but i am unsure how it would help me, is there an ADB format command?
if anyone can point me in a direction it would be much appreciated!
thank you :)

You should be able to do it with a factory reset: Undo Android 4.0 (aka Ice Cream Sandwich) Full Disk Encryption

i've done that and then during reboot it still asks me for my pin/password meaning the tablet is still encrypted, i am still unable to access the internal memory (/sdcard) from CWM

You can try to format it in CWM. PS: upgrading would have worked with a newer cwm 6.0, hat offers the 'adb sideload' command. Also, it would've worked this way: http://android.stackexchange.com/questions/19286/will-a-custom-recovery-work-with-an-encrypted-device/23879#23879

hmm i have samsung galaxy tab 8.9 (gt-p7300) and i dont see CWM 6 available for it on xda.developers :/

Haptic feedback settings in Android 4.1.1?
Just got a Samsung Galaxy S3 mini with Android 4.1.1 factory installed. The phone is not locked to any carrier. My problem is that I can not for the life of me find the setting to turn on the haptic feedback, neither for the keyboard nor other touch events (such as the menu button, etc.). I've looked through the settings menus several times without finding anything.
The actual vibration hardware is working, because if I go to Settings -> Sound -> Device Vibration it vibrates.
The only other mention of this issue I've found was one unanswered thread on the Samsung Galaxy Forums.
This is the kind of thing that makes me wonder if Google (and others) are actually trying to make things worse with every update. My HTC Nexus One running Android 2.3.6 never had any oddities like this. Only problem with that old phone is it's limited internal memory.

Have you turned keyboard vibrate on? System Settings, language and input, android keyboard clock the little settings icon on the right, vibrate on key press checked.

See this Post #7 seems to be the only fix so far, provided your are rooted, However, there's this app on Play Store that may just do the trick for you.

Thanks, now I at least have vibration in the keyboard. It turns out the stock Samsung keyboard does not have a vibration setting, and the phone comes without the Android keyboard. I ended up installing my trusty old Smart Keyboard Pro, now I have both vibration and arrow keys for moving the cursor (my old Nexus One had a trackball for this). Seems I'll have to live without system wide haptic feedback though, which really is a shame. It seems that every update introduces more bugs than fixes... sigh...

System Sounds > vibrate on touch.

I finnaly found it and I hope it helps:
Unless you already did so, go to Settings→Language and Input, tap the setting icon on Samsung keyboard, go to Advanced, and uncheck Vibration and Sound -- depending on which one you want!
This works for the jellybean update ok 4.1.2 . Hope I helped!

In some versions of Jelly Bean the setting for activating haptic feedback is hidden. But there are a couple apps that can be used to enable it:

Quick Settings, a plugin for All-in-One Toolbox
Spare Parts

Modifying stock firmware
I would like to modify the stock firmware to remove certain apps which i do not want to have available on my phone.
The source code for my phone is available on the Samsung website but there is no information on how one goes about in actually customizing building and installing it.
For an open source project its kind of weird that the information is not readily available on a quick google.
Any pointers to howtos or articles would be highly appreciated.

What phone is it?

Isn't this rather a XY problem? Do you want to build your "custom ROM" -- or do you simply want to get rid of the "bloatware"?

I would like to do both, in the short time remove some samsung and google applications from the build. The recent google search app wants access to my camera etc etc. I don't want that i would rather use the web search than give a remote application those kinds of permissions

The phone is a samsung galaxy note 2

Apart from the AOSP code that Google provides, Android devices also require lots of device specific code, especially kernel, GPU drivers, radios etc. These are released by the manufacturer some time after the official update is out. 4.2 source is out only for some of Nexus devices yet (and not all of them).
Nexus devices are the easiest to build custom ROMs on, for obvious reasons. If your device source is released, you can find specific guides for devices - like Nexus 7 Galaxy Nexus, Nexus S(which I use), Kindle HD etc. Google "compile jellybean from source" and you will get guides for your device (4.1 for now).

I will check these out and see if i can adapt them for my galaxy note 2

You should have mentioned that you have a Galaxy Note 2, it's source for 4.1.2 is out already. No official 4.2, so you can't compile any ROMs yet.

Gmail Notification stopped working on Nexus 4
I have to press the refresh option in Gmail just to get new messages.
I have checked the application and the notification setting is on. I stopped it and then again started it but still it is not working. Is anyone else facing such issue? Android version is 4.2.1
In my accounts it is showing that "Sync is OFF". Has this something to do with this? I always see this option like this and have to go inside it to change Gmail, Currents, Photos, etc. to sync.

If in your accounts Sync is turned off, that's normal behaviour. Turn Sync on if it should retrieve new messages automatically -- that's what Sync is for.

Thanks. Actually there was no option coming for setting the Sync on, so i have to remove the account from the device and added it again, now it started working.

That's strange. Usually one goes to Settings->Accounts & Sync and can switch Sync off and on again there. Anyhow, as you've solved it (congrats;): Feel free to add your own answer below to show there's a solution for others to find!

I found this link which solved my similar issue. It walks you step by step on possible solutions. Mine got solved by removing the cached data of the Gmail app and restarting the phone. Note that this will erase your settings such as signature and notifications settings. I couldn't post an answer for some reason so I'm posting as comment ... The link - Problems syncing Gmail on Android - https://support.google.com/mail/troubleshooter/2650727?hl=en#ts=2650682,2661639,2661709,2661688,2661691,2661695,2661719 - Good luck!

On stock Android 4.2.2 on my Galaxy Nexus I had the same problem of gmail notifications not working. I checked that in Settings>Data Usage "Auto Sync" was turned on.
Then I went to Settings>Accounts>Google, hit the email address and you see everything that is being synced or not.
Weirdly for me it Gmail sync was inactive after I had recently updated my rom.
This should take care of this problem.

I recently ran into this issue with my phone after downloading a Battery Saver app that I noticed had turned sync off after I had uninstalled the app.
I read through all the comment answers above and no one came close to the Stock ROM 4.2's data sync setup. In the (current at time of post) latest Version of Android the "Accounts & Sync" has been removed and all accounts are inline in the Settings ListView.
Individual Accounts will only let you sync now, there is no option to "Turn Sync on" or "Auto Sync"
My setup:

Verizon Galaxy Nexus
  Android 4.2.2 Stock ROM
  Build Number: JDQ39

What I did to resolve:
Go to Settings->Data Usage->Menu->Click Auto-sync data

Unix domain sockets between host and emulator
I am trying get Android and my Linux host talk to each other on Unix domain sockets.
I have my server on the host while the client is part of a library that emulator's software stack will make use of. The Android stack is not able to find the socket stream file that I have specified which happens to be on the host's filesystem.
Now, before you say "port forward", I have tried that and this is what I have tried based on my understanding of the abd forward command. I have not had success in this. Could you guys please point out the mistake and help me?
adb forward localfilesystem:/tmp/android_socket localfilesystem:android_socket

The path used in the host is /tmp/android_socket and that in the Android emulator is "android_socket"

development question?

Not necessarily. IPC (inter-process communication) is useful in development, sure -- but there are certainly some "civil use-cases" as well. The question does not directly target at development, so I'd say it's valid here.

@Izzy That's what I thought!! :)

Highly doubt the emulator has the capability to do just that! The Android stack is not able to find the socket stream file that I have specified which happens to be on the host's filesystem. Why not use plain old fashioned TCPIP ports instead of Unix Domain... think that's outside the scope of the emulator!

Unix domain sockets are meant to be used for interprocess communication on one host, not for inter host communication.
Sockets that are located on the filesystem like you describe are not unix sockets, but named pipes, and are also limited for use on the same host.
For inter-host communication, you need to use network sockets of some kind.

+1 from me, correct, as I have commented previously above! You've confirmed it :)

folder not visible
I have a Samsung Galaxy S2, running Android 2.3.
I have folder named usbStorage. After the firmware to latest version (via Kies), I can't see the usbStorage folder. When I mount the storage via USB mass storage mode, I can see that folder with all my content. I tried to copy some files in that folder, but no luck. When I connect the phone to MTP mode, I can see the folder but it's empty.
Is there a way to get back that folder? I can move all my content to another folder, but then I need to rewrite my applications that depend on that.

here are my two cents, the file browser samsung bundles with their firmware doesn't always show you all the files tree. you might want to try moving the content of the folder to another location visible to the file browser, or, if you're feeling adventurous, root your device and install a better app like root browser.

then why they showed that folder in 2.3.3 version? Also i deleted that folder and after remount memory to pc, the folder was created again. And also my own application can't see that folder. looks like it is locked by OS. I moved all content to new folder.

Insufficient memory with sandisk 32GB micro SD card while having 20GB free space
I have a 32GB micro SD card and I've been downloading my music onto it and I've used 8GB on the card so far. Then I was downloading a song and it said insufficient memory. On my phone the songs automatically go to SD card. So I went to storage and it reads the card and says 20GB free space but any app or music or anything cannot be downloaded due to the supposed insufficient space though I know that it's just not true. If anybody else has had this problem please let me know. Any advice would be greatly appreciated.

Try downloading SD formatter. it will format the sd card but it will also fix the partition table. maybe your partition table is all messed up

OK great. That sounds good to me. I'm going to try SD formatter right now. Thank you very much for taking the time to help me. Greatly appreciated...

"insufficient storage" though nothing is installed
I can't download any apps onto my android tablet. I have put it back to factory settings and it has nothing saved on it at all and is still telling me I have insufficient storage. I can't even install the cache cleaner.

Welcome to Android Enthusiasts! I've just added the insufficient-memory tag to your question. Please follow up to its tag-wiki: as that's a quite frequent question here, we've compiled some first-aid there. Check if that helps you, then come back here to answer your own question if solved or edit it and let us know what you've tried and where you're stuck.

Hi and welcome! What make and model of tablet? How much storage space does it include? Have you "rooted" it?

This a common problem faced by rooted phone users.
If you have any app that links your files to Sd like link2sd, luckypatcher...
and your phone doesn't support it. You'll have to revert all this apps setting to get the memory back. The actual problem is that you are linking to a directory which doesn't actually exist.

How to transfer both SIM and phone contacts to a new phone?
I have a Samsung Galaxy Ace2 and a new Samsung S5 Mini. I have completed the smart switch but it has only transferred contacts from the phone not the sim.
Can you  please suggest me a solution to transfer all the contacts(including SIM contacts) to my new phone?

Related: these 12 questions with answers // Welcome to Android Enthusiasts! I've just created a "special search" for you, as similar questions have been asked and answered in the past already. Please take a look at the results. If you cannot find a fitting answer there: please return here, [edit] your answer, and point out what you've tried and where you're stuck. Good luck!

You can use Super backup SMS and Contacts from play store.

You can try using the adb pull command
adb pull /data/data/com.android.providers.contacts/databases/contacts2.db

from your Samsung Galaxy and restore it to your Samsung S5 mini

Corey, that only works if the device is rooted. And to transfer that, the other device had to be rooted as well. Talking about different devices here, this method is dangerous: different ROMs sometimes use different table structures, so the restore might break the target device here (I had that once with the mmssms.db, so I know what I'm talking about).

Micromax Unite 2 A106 updated to Lollipop version and no network or sim detected
Using Micromax Unite 2 A106, updated to latest version of lollipop, after finalization and restarting my phone is not able to detect any SIM/network. Also no display of selection of Mobile network is displayed in the Settings.
If I try to dial any number the msg "Please close the airplane mode" is displayed. I tried reverting back to old version, removing the battery for 5-10 min, replaced another SIM network, but no change in the problem

Are you sure the Airplane mode is turned-off? And do you have any app that enables auto-airplane mode? If so please disable and check.

Lucky - i don't know but no network is shown on the taskbar ; + when i dial a no. a msg shown that turn off the airplane made

Please post some screenshots: 1) when you dial something and see the airplane mode message, 2) default home screen, and then of quick notification bar, 3) Settings and then Settings -> More, 4) type *#*#4636#*#* -> Phone Information -> and take screenshot, select preferred network mode and take screenshot. 5) Go to Settings -> About and take screenshot. Remember to post all these screenshots.

me and my sis using this phone for almost 10 months...
First my sis upgraded her phone by downloading the official fota upgrade file from her phone and installed it. She also got same network issue.
Then I went to nearest service center and ask them about that issue and they had told me not to install by your own because it will delete the IMEI registration.
Then i had upgraded mine and my sister's phone to lollipop 5.0 in nearest service center.
Hope your problem will be resolved soon...

i understand and got same reply from company's service centre,

If the Plane symbol(✈) is displayed in you notification you have your airplane mode turned on. This wont allow outgoing/incoming calls and displays a message to first turn off the airplane mode to make calls.
Goto Settings -> More -> Airplane Mode -> Toggle off.
Or Simply open your notification by swiping from the top of the phone screen and tap the Airplane mode and now you will be able to make calls.

Also if you have any auto-airplane mode apps installed please disable it. If nothing works atlast you need to flash stock ROM firmware your Micromax Unite A106 or claim warranty and replace your device. Related

i understand , but there is no plane symbol on the taskbar ,there is message to turn off the airplane mode when i try to make a call,also there is no detection of the sim cards/network by the phone ,even in the setting

the airpkane mode is completely stopped by me then also the msg when calling

@HimanshuShah Have you installed any tasker of auto-airplane mode apps in your phone?

Your answer unfortunately doesn't address: Also no display of selection of Mobile network is displayed in the Settings. Airplane mode doesn't hide Mobile Network settings.

@Firelord OP doesn't said the setting is hidden and what he meant to say is he wasn't able to make a selection of the mobile network(toggle of sim card enable/disable)..and only when the airplane mode is on I'm unable to enable the SIM network. It takes no action on selecting the toggle button and no message is displayed.

Up until Kitkat, ''Mobile Networks'' was under Settings -> More, and "Sim Management" (for dual SIM) was under Settings for Micromax devices. In my Lollipop (single SIM, other OEM), "Mobile Networks" is directly under Settings. That said, in Kitkat if Airplane Mode is enabled then you can always see the "SIM Management" but not toggle while "Mobile Networks" is always greyed out. Are you saying that all of this has changed in Lollipop? I guess OP could make this clear by posting the screenshots I asked.

@Firelord in my Lollipop dual sim now I have Settings -> Sim cards which shows two SIM cards names with a toggle to enable/disable. I can't enable(greyed out) both the SIM if I have Airplane mode turned on. And the Mobile Networks is under Settings-> More -> Mobile Networks. It is greyed out when the Airplane mode is enable or When I completely remove the sim card whether or not Airplane mode enable/disable.

This happens because your IMEI number got wiped. There are many tools online that can help you restore your original IMEI number.
As this phone has a Mediatek chipset, it shouldn't be hard to do that by your own.

How do I remove the 'Whatsapp' button in Firefox's menu?
The big green button in the second row of the menu, shown in the image below. It does not appear as a Firefox addon, and Whatsapp itself doesn't seem to have any option regarding this.

Screenshot - Firefox (Click to enlarge image)
And how can I prevent stuff like this getting added to Firefox in the future? This seems to have the same potential for abuse as the desktop browsers' 'toolbars' system, and I wish to preemptively disable such changes to the browser.

Whatsapp is the last app you used to share a link.
To change it to something else, you need to share a link with another app, or if you want to remove any app icon from the menu, just uninstall and install the app again.

Is there a way I can disable this feature in Firefox entirely? The general share button in the first row's right is good enough for me, this 'last shared app' taking up an entire row is superfluous to me.

@sundar As much as I know, you cannot disable this option. It's on most of the apps, including gallery and Google Chrome.

That's the last application you shared with.
Share with another application or just ignore.

Best file system for an external SD card
I have a Galaxy S5 with Android 5 and got a new 64 GB SD card. What is the best file system for the SD card? FAT32 is not an option because I want files >4GB. Which file system offers the best performance ? Thank you for your help.

The only file system you could possibly use is exFAT, because NTFS is not supported by Android. Others like ext4 or similar may or may not work depending on the ROM and how fuse handles them.

Is ext4 not supported by Android itself?

Depends on how fuse handles it. On the one hand I heard that it works like a charm and on the other hand it doesn't. Try it out and report back if can.

One more thing to consider is whether you might wish to access the card via an external card reader one day – because that then would require the FS being supported by your computer as well. Not a big deal if you're using Linux – but with Windows, ext4 might limit you to read-only (if you manage even that at all).

I guess this should be Trial & Error... test some filesystems and see what fits your needs

The answer to your question is built into your phone's OS.
1. Put the SD card in your phone
2. Reformat the SD card with your phone(Settings --> Storage/Storage & USB)
3. The file system on the freshly formatted SD card is the type that will give   you the best performance with your phone.
4. Outside the context of your phone the optimum file system is another story.

An important point: best in speed, but the last in stability.

Yes, I consider exFAT as good filesystem for SD cards, but it's not supported on my old Android :-(.

Answering the question, the filesystem used on standard Android devices is "exFAT", which is available from Windows Format application and Android's own filesytem management tools. Hope this cleared your doubt.

can you elaborate more on why it is best?

And also please give a reference on exFAT being the standard? To my knowledge, Android usually doesn't even support exFAT out of the box (due to license issues AFAIK).

https://en.wikipedia.org/wiki/ExFAT

FAT is just a /dev/null that occasionally stores things, I'd expect a specialised flash file system e.g. JFFS, YAFFS to be more robust.

I'd expect a specialised flash file system e.g. JFFS, YAFFS to be more robust are they supported on Android out of the box?

Ext4 should be supported because Android always supports that internally but unfortunately, the SD card is treated differently and even Android One phones do not support Ext4 for the SD card. The Nokia 7.2 Android One phone will not support Ext4 or exFAT or F2FS for the SD card filing system. FAT is the only option in 2019 !

As far as I understand you should avoid used exFAT as it is much less stable in regards to errors than FAT32, NTFS or other filesystem that can handle multiple read/write better and has multiple file tables.

As far as am aware Windows only supports fat32 if your sd card is under 8g if is over exfat or ntfs. ext4 is only for Linux distros
