How can I unlock my phone? I locked it using Android Device Manager, but it claims I entered a wrong password
I have an Samsung Galaxy S3 Neo.
Bus 002 Device 042: ID 04e8:6860
Samsung Electronics Co., Ltd
GT-I9100 Phone [Galaxy S II], GT-I9300 Phone [Galaxy S III], GT-P7500 [Galaxy Tab 10.1]

The keyboard & language setting is português.
I today installed Android Device Manager and to test it's functionality I locked the phone with the password: "abcd" (4 letters were required).
After entering the password and confirming with the "OK" button of my keyboard, the phone showed me that the password is wrong. "Senha incorreta".
I reset the password after some tries to "123456" and the phone reloaded the lock screen. Again the password showed up to be wrong. I also tried the alphabetic password: "abcdefg" - same error.
I changed the language of my Google account from German to Portuguese and reset the password to "123456" again and I tried to really reboot my phone and unlock the SIM card again. But anyways I can not get through my lock of the Android Device Manager.
I tried to enter the password 35 times wrong with hope to get a chance to authenticate with my Google Account login.
I also tried to connect the phone with adb but it does not show up in this state with:
adb devices

So what can I do to get access to my phone again?

Just a thought, from my recent experience when an Android tablet started doing something I couldn't explain: Does the phone have a documented "reset to factory configuration" operation? You'd lose everything you'd installed on the phone so far, but if you've backed up fairly recently, and/or if you haven't customized it too heavily, that might be acceptable.

related: Android lock screen won't accept password from Android Device Manager

I tested this on a Nexus 5 (v5.0.1) running UK English. I locked the device with Device Manager then, without unlocking it, I used Device Manager to lock it a second time. I then used the second password to unlock the device. So, you should be able to change the lock password using Device Manager - it seems that only the last lock password is required to unlock it.
You can use a one character password to lock the device. Perhaps give that a try?
Another thing you could try (assuming you are using the web page to lock your phone) is to use Device Manager on a different Android device to lock your phone. Perhaps there is something wrong with the translation between the characters in the language entered into the web page and those entered into your phone.
Hopefully someone else might have a better answer than this. :(

I tried éééééé as a password but the phone claims again that the password is wrong.

@tokam, perhaps use a single character (rather than six characters), and make it a simple ASCII character without an accent? For example, just one letter 'a'. As a lot of Android development happens in California, it wouldn't surprise me if an accented e caused problems. :)

Does not work too. The phone was new from today. I invested 2 hours to configure all. I will wipe it now and try to reproduce the problem.

Oh! If there's nothing important on the phone, maybe test Device Manager's "Erase" function. :-)   If you can reproduce the problem, make sure you file a bug report with Google.

@tokam: Immediately before you try to reproduce the problem, may I suggest you do two things: 1. Enable USB debugging. 2. Make a full backup of your phone, apps, and all of your custom settings. Later on, please let us know whether or not you manage to reproduce the problem.

How to do that backup? Just copying some folders?

I reproduced it. I will now wipe the phone again.
How to create the bug report? At the Google telephone support where I ask (before wiping the firste time) the lady gave me this obviously wrong link:
https://support.google.com/chrome/answer/95315?hl=en

I created the bug-report: https://code.google.com/p/android/issues/detail?id=93132&thanks=93132&ts=1420376781

Wrong Forum: Status closed!

@tokam My apologies. I gave you the wrong link - that was for developer related bugs. This is the one you need: https://code.google.com/p/android/issues/entry?template=User%20bug%20report .  As well, I would suggest putting as much information into the bug report itself, rather than linking to this website. Finally, it would be interesting for you to try setting your phone to US English and trying to reproduce the problem. My guess is that it would work properly, in which case you'd have evidence that the problem is language related.

https://code.google.com/p/android/issues/detail?id=93741&thanks=93741&ts=1420586269

@tokam: How to do the backup? I don't know. You can post a separate question if you like.

@tokam: Android Device Manager (ADM) is closed-source. There is no public bug tracker. Instead, go here, click the gear icon, then click "Enviar feedback". I recommend that you type your message in both your native language and in English. If you want an open-source alternative to ADM, you can use Open Device Manager instead.

I was having the same problem with ADM. I went to https://findmymobile.samsung.com and went to protect device (left hand side). I then clicked "Unlock screen". Took a minute but worked fine.

It seems like you did not use the Google Device Manager. That's why you received a vote down (from someone but not me). I was not able to solve the problem.

That's true. But the question didn't say that it needs to be unlooked via device manager. Also this way of unlocking your device will still work even if it was looked via device manager.

How did you lock the phone? With device manager?

The reason it won't work is that the current version of Google's ADM does not change the password when the lock screen is already applied. The current reasoning is that it is there to lock a device that was lost/stolen, not to change the password when forgotten. So even though it says it works, it isn't. There is a message that may pop up saying:

Since Google has verified that a screen lock is already set, the password you entered won't be needed.

Though it took a bit for that to pop up on ADM, and it goes away quickly. Thanks Google.
On top of that, Samsung's proprietary changes to Android also complicates things. If the device is also registered with Samsung via Find My Phone (The Samsung Device Manager), it needs to be unlocked from there.
There is no other normal workaround. Another option is to flash a custom recovery, and unlock it via root methods, highly depends on the phone.

Broken Samsung Galaxy S4 screen.. (not working) need little help
I have Samsung galaxy s4. I have broken screen which is not working and it's completely dark. Am I right that I need to change digitalizer and LCD screen ?
I am looking to buy from ebay co uk, which one would be the best the genuine or other brand ?
There is many videos on youtube, is it that hard to replace on my own, as I have to take out camera etc. Is there any safety tips what should I follow ?
Thank you.

If you are doing the replacement yourself, you're best to replace the entire front assembly. See the warnings as to why on this page.
I would personally recommend the genuine item as I would have no idea where some other brand came from. I'd guess they would be refurbished items as these panels are made specifically for the devices. Using one might be a gamble, but I honestly don't know.
There are many safety tips, including having the right tools and ensuring you have grounded yourself. Prepare by watching the videos carefully, reading other documentation, and ensuring you know exactly what you will be doing. Don't force anything or the little bits will break. Ensure you have a lot of light in your work area, and that you have containers to put the little tiny screws and parts into.
My most important tip is to warn you that there's a reasonable chance you will damage the phone if this is your first try at fixing one. You need to balance that fact, as well as your own abilities, against the cost of having the fix done for you. I don't want to discourage you from trying it, but you need to be realistic about the possible outcomes.
Best of luck!

Unwanted Google Keep reminders when Google Keep is not installed
I use two Android devices regularly.  A Nexus 5 which is my daily driver, calendars, Google Keep, etc.  The second device is an Asus Tablet which I use to consume - newspapers, news, magazines, internet, etc.  I try to minimize all the alerts on this tablet since I don't need any notifications from my calendar or other daily apps.
I am a heavy user of Google Keep on my Nexus 5 but have not installed it on my tablet (on purpose).  And yet, each time I set a reminder that I want to see on my phone, I also get a notification on my Tablet of the form (e.g.) "Pick Up Eggs - Install Google Keep".  It also uses the Google Now reminder icon (finger with a bowtie) and not the Google Keep icon (lightbulb).  I should also mention that I do not have Google Now enabled on any of my devices.
I do not want Google Keep nor the reminders on my Tablet.  I've tried removing various sync services under the Google Account but can't seem to find the one that is synchronizing the Google Keep reminders to my Tablet.
Any suggestions as to how to get rid of these useless notifications?
Thanks!

Hmm.
Can you see Keep under Settings > Accounts > Google > <<Your google account address>> > Sync Keep on your tablet?
Edit: I just realized that you do not have Keep installed on the tablet...
Well, maybe a stupid patch could be to install it on the tablet too, and then disable synchronizing?

To answer anyways... no I can't see Google Keep under the account.  Installing and disabling sync is worth a try though.

Doncho, I installed Keep and then disabled sync and it had the required effect.  Notifications disappeared.  I'll accept the second half of your answer.  Thanks.

I had the same issue. When the notification appears pull down the notification bar. From there hold down on the Google Keep notification. A little pop up with 'App Info' will appear. Click on it. That will show you what app is causing the pop up. From there you can either disable the entire app or disable notification. For this insurance it looks like it is Google Play Services that is the culprit. I choose to disable the notifications only.

Won't this supress a number of other important messages?  It's a common framework for a number of things.

What you can do is install google keep again and go to trash there you will find the note with the reminder ,then delete the reminder and delete forever and that got rid of my reminders

How to get missed/undelivered messages on whatsapp?
For some reason I uninstalled WhatsApp. If I reinstall it after a day or two , will I receive those messages which might have been sent to me during this period? If not ,Is it possible to get those messages somehow?

Unless you delete you WhatsApp account, you should get at least 2day old messages delivered after you install WhatsApp next time. Congo.

AFAIK, as soon as you removed/uninstalled WhatsApp from your device, the other people will not be able to see your contact of whatsapp. Hence, they will not be able to send you message anyways. And, of course when you re-installed whatsapp again, they can connect with you too.

I think it is possible to get those messages. When you reinstall whatsapp giving your phone number, it asks whether you want to recover your older messages. You have to select Yes. It recovers only upto a certain date.

What happens to a call when the reciever is busy
I have a doubt. What happens if i call a person who has an android mobile and the person is speaking to someone else. Will the android mobile store my number in its recent calls or will it not recieve the call and not store the number? Is it dependent on the network providers service or its wholly android controlled?
Thanks in advance!

Depending on the carrier of the receiver and its configuration, it is possible that your call will knock on ie. the receiver gets a sound that notifies him about an incoming call.
If he wants he can create a group call (I never heard about someone using that feature).
If that knock on feature is disabled you should go straight to the receivers mailbox and you will be listed in missed calls.

Can you pls explain how i will be found in the receivers mailbox?

He will probably get an SMS from his carrier that says that he has a new message in his mailbox. If I used the wrong word for your voice mailbox, I'm sorry

S5 Not Getting Detected On Laptop
so I just got my phone today and had it unlocked. So- it got rooted. I don't think that's the problem though. Anyway I tried to connect it to my laptop and HAZZAH- Nothing happened. It didn't get detected. For a second it was installing the driver then after that nothing happened. All I've been doing for the past 2 hours was uninstall drivers and reinstall them and nothing even happened. Right now I'm just using AirDroid, but since sometimes I don't have WiFi I really need the USB Cable thing to work. No idea what to do anymore. I also tried Kies, and it wasn't detected. Apparently my phone was incompatible. I checked and it was. So that really confused me.
For some reason, when I go to storage, it doesn't allow me to go any "menu", since the menu button has now been replaced with a recents tab.
By the way, it shows up in Devices and and Printers as an unspecified device and is named SAMSUNG_Android. If that is any sort of relevance.
Just to clarify, I've done the following:
1. Restarted my phone AND laptop
2. Uninstalled and reinstalled the drivers
3. Changed which USB port it was in
4. Unchecked tethering
5. Enabled USB debugging
If you are to help me and have any knowledge on what to do, or feel like I did it wrong, please let me know how to do so with step by step instructions. Thank you and have a good day everyone!

possibly related: My Samsung Galaxy 3 (GT-i5801) is not being detected by my PC — What should I do?

I think it is driver problem.

Download latest Google USB driver click here.
For install driver follow this steps Installing driver

I hope this help you

Note that step 1 is only for Google devices. For non-Google devices, each manufacturer has its own OEM USB drivers that need to be installed.

This answer could be helpful. I expect rooting got nothing to do with it. Samsung connecting to PC been nightmare for me sometimes and specially S3 which was depending totally on the cable.
If I were you I would trace this problem by starting to try the same phone and cable on another machine (pc or laptop) if possible and see if that works. Clearly if it does, the problem in the driver installed or sort of settings mess. If it doesn't, try another cable. Try turning off USB debugging and connecting the device on different machine as well.

get a better quality cable. cheap cables are only good for charging.

There is no surety that this would work. I think this should be a comment until OP  confirms the case.

Android restarts when I press "Turn on USB storage" button
I have an ACME TB709-3G tablet with Android 4.2.2 installed on it. I was able to connect this tablet to my Ubuntu 14.04 TLS laptop before, but recently when I press the "Turn on USB storage" button, Android restarts.
What is the problem and how can I fix this issue?

Resetting might solve your problem

Tried it before. No change.

Did you enable restart on "unauthorized" USB connection? Also what tablet? Custom or stock ROM? Debugging turned on? Can you access through ADB?

How can I check this "restart on unauthorized USB connection" option? I can not find it. My tablet is ACME TB709-3G. Debugging option is not available in my settings!!!

Goto settings>about phone/tablet scroll down to bottom and tap on "build" 7 times. Back once to main settings page. Scroll to developer options. Check your setting in there.

Ok. Debugging is turned off and I have no option like "restart on unauthorized USB connection" there.

@HasH_BrowN Athar can't comment(posted it in an answer) but wants to say, I assume to you: "There is no such option like "restart on unauthorized USB connection' in Developer options. My phone is rooted Micromax canvas 4 A210. 4.2.2 Jellybean."

options for fixing USB not authorized
(On device)

Go to settings/about device, scroll to "build"

Tap on build 7 times to enable developer options
Back out to main settings screen, goto developer options
Enable USB connection

or

(On device)

Using a file manager that has root access

Remove "adb_key"

/data/misc/adb/adb_key

Reboot your phone and try connect again.
The confirmation message should popup after a short time.

or

(On PC)

Remove the "RSA keys" from SDK settings
~/.android/adbkey

Start up ADB

$ adb kill-server
$ adb start-server

Plug device back into USB port (not hub) and wait.
Confirmation notice will popup after a short time period.

or

You can try this. The steps are more involved, requires device and vendor IDs

this has been included because it is helpful and a reference
steps haven't been included in the answer because it is off topic

in step 3 (~) is the location of your SDK installation
make sure you have the latest adb executable installed
make sure you have the latest drivers for your device
make a backup before performing any of the above steps

Cannot access /sdcard/ (internal storage)
After I got my phone restored from an nandroid backup, I found almost all apps cannot gain access to /sdcard/ (internal storage), including ES file manager, Z archiver and so on.
When any of these apps access /sdcard/, or any other equivalent folders like /storage/emulated/0, /storage/emulated/legacy, /storage/sdcard0, they only shows a blank directory, and I cannot create any file or folder.
When I try with the stock file manager (My files), it does show the files, but i cannot rename, edit, or create anything.
Android File manager is able to copy most of my files out. But It stucks when I try to create a folder or send something.
I tried to re-flash the same ROM again (which worked perfectly before), the issue remains. I have backed up important data from /sdcard/.
In terminal emulator,
cd sdcard, ls gives opendir failed: permission denied.
Then I tried su, ls shows the correct directory.
How should I fix it?
Extra: I found a new folder called knox-emulated in /storage which is not there before. External SD card (/storage/extSdCard) works fine.
Device Information:
Samsung Galaxy Note 3, Android 4.4.2 Rooted, with a custom ROM modified based on the Stock ROM. Custom recovery installed.

Did you try setting SELinux to permissive? That should fix it.

Try moving your primary storage in settings.. go to apps scroll all the way down and change your storage from phone to sd storage and vice versa. And you should be able to access everything on sd card etc. ES file explorer is a great free app in case you couldn't get it by changing storage in setting

I ended up encrypting my SD card. And found that out when I typed SD in the search bar of my Android Galaxy J3. And it show Decrypt SD card. I tapped it and tapped Decrypt my SD card is back to normal.

"Can't reach Google at the moment" when using Google Now
I have Nexus 4 running on Lollipop 5.0. Everytime I input a command via voice, or typing to set a reminder in Google Now, I get

Can't reach Google at the moment

I've changed languages from English (US) to English (IN) with no results.
Does anybody know a fix for this? Alternatively, is there another way to set reminders via voice command just like Google Now?

Anyone searching for a fix either refer to the answer or you can check the discussion at https://productforums.google.com/forum/?utm_medium=email&utm_source=footer#!msg/nexus/eoGV3ReWCrQ/wD3mcZL3zF8J

I had issue with reminders not working and that was "fixed" by going into app settings and then Accounts & Privacy, turn ON Search with Google.com
Now commands work properly? Must be a local server issue.

I didn't do anything. It just automatically started working after some days. Idk what was wrong.

Wow. I'd tried nearly everything short of throwing the phone at the wall but this worked. What's the best way to make GOOGL aware of this crazy bug, given it'll be outside the AOSP?

I don't have a "Search with Google.com" option. Is this in the "Google Settings" app > "Search & Now" > "Accounts & privacy"?

@harbichidian In google now, the app drawer icon (three stacked lines) next to google search box, Settings,Accounts & Privacy, Search with google.com = ON

@Darren unfortunately all I get are some Google Account options like SafeSearch and Nicknames (http://i.imgur.com/p43vltr.png)

@harbichidian You has less options than I do, not sure why.  FYI I have version 4.4.11.16

Make sure the 'Google' app is also updated in the Google Play store

I only had this problem while connected to my home wifi.  It would only work once in a blue moon.  The other voice to text functions worked fine though.
I decided to log into my router and change the default DNS servers to some free opendns servers.  Fixed the problem right away.  Hope this helps someone.

I have the note 4 and I had to go into settings >> Accounts >> Google >> Search. There the option 'Voice & Audio Activity' was paused. I selected and turned the switch on 'On' and google voice search is back into action.

In Google now cards...Settings>Now Cards>Delete card preferences
This will disable now cards.
Re-enabling will bring it back.

Does this fix the issue or is it just for disabling Now?

What's the easiest way to automatically backup my phone's data?
My goal is to have backups of my phone (Samsung Galaxy S3) created regularly and automatically.
In case it get's lost or stolen, or damaged or reset to factory mode, I would like by one click to recover (at the same or an other phone) the current data:

App-settings
E-Mails
SMS
Contacts
Apps
Phone customizations (language, desktop widgets, background...)
Photos/Video
Mp3-Data

I prefer the backup to be at my computer, but I do not mind backing up in a cloud if it is provided by a bigger company.

If you are rooted a Nandroid backup is the most complete backup you could possibly do, otherwise you should try Titanium backup

Thanks. Is it recommenadble to root ones phone?

As to your question whether rooting is to be recommended: depends on, you might wish to take a look at our rooting tag-wiki and the information linked from there. Concerning your original question: What OS are you using on your computer?

I am using Ubuntu.

Most phones have a back up and reset option in settings. I went to that and clicked on everything I wanted backed up. I backed up everything to my Sd and E-mail.. (Google servers)..

Can I get a virus on Android 4.4.2 by clicking "no thanks" on one of those virus browser pop-ups?
I opened a link using the built-in facebook browser yesterday, and pop-ups on the website kept asking me if I wanted to install some anti-virus and they had two options: No thanks and OK.  Normally I press the back button because I'm wary of clicking anything, but this time I clicked "Cancel."
I've noticed some weird behavior with my phone freezing this morning and now I'm paranoid.  Could have clicking "Cancel" actually installed something?  Was the message box option spoofed?

Well it's hard to know. Install avast anti-virus from google play and it will show any viruses (if there are any). But that 'Message Box' shouldn't have appeared, so that means either Facebook was hacked or you were using a fake Facebook app/page. Clicking 'No Thanks' on a webpage can't install anything unless you already have a virus on your Android. You should be safe if you were using the genuine Facebook app/page and that Settings>Security>Unknown Sources was unchecked.

I was using the genuine facebook app, which now has its own built-in browser for when you click on links in facebook posts.
Are you really positive that clicking a pop-up message box can't install anything?

I can also confirm that i have Settings>Security>Unknown Sources unchecked!

The only way anything could be installed is by installing it from the Google play store, A apk (Unknown sources HAS to be enabled, ADB). But there is one way in which something can happen: If you have a application installed on your android, a link can open it and start a action (Such as using loads of RAM). Do you remember what it said in the message box?

And clicking 'No Thanks' can open a link but definately not install anything

Finally found it again:  "The page at "http://quickscanner.co" says: === Android Warning === Is your Android browser outdated?  Tap 'OK' to download the latest now!"  And there are two options: Cancel and OK.  I clicked Cancel.

Ok then if you dont have any suspicious apps then you are 100% clean no need to be paranoid! I still reccomend installing avast because it will stop things like this happening again!

Please check this answer if it solves your problem

I installed Look Out.

Password Lock-out
I've mentioned this on another similar question. I haven't used my Android Tablet for maybe a year now, mostly because I had lost the charger. I found the charger and thought "Why not?" so I charged it up. To my dismay, I had a put a password combination, locking me out until I remembered the password from last year. I've tried every password I can think of, and I'm still locked out. Supposedly, there's a helpful "Forgot password?" button I can press and fix this whole mess. I can't find any such button, and I can't factory reset (I've tried out of desperation). Anyone know how to fix this???

possible duplicate of Recovering from forgotten lock pattern

You might wish to take a look at Cannot unlock tablet as have no internet connection? – which mentions a lot of possibilities. If none of those work, please [edit] your question to tell what you've tried and where you're stuck. Also let us know why you "can't factory reset" – how did you try that, and what happened?

Alright the reason that you can't see 'Reset Password' Is because this feature isn't available in earlier versions of android. To reset your password you can use this, If that looks a bit to hard or doesnt work you can do a hard reset WARNING THIS WILL DELETE ALL OF YOUR DATA (This includes pictures, game data, Music, Videos, everything) Here is how to do it: Turn your tablet off (Shut down)Press the volume - button and then with that pressed press the power button until your tablet screen turns on and it will go into the recovery mode (If it doesnt try using a different key combinaton like: Home+Power, Volume Up+Power)Now using the volume up and down keys select 'Wipe Data' (Might be 'Format') then press the power buttonUse the volume keys to select 'Yes' out of the list of 'No's then press the power keySet your tablet up again

How do you move an app from the internal sd card to the external sd card
Can someone answer my problem? I have a digital2 deluxe II tablet containing an internal storage of 1.97 gb and an internal sd card of 3.74 gb and it's kinda full and my problem is I have an external sd card of 32 gb and everytime I press move to sd card it moves the app to the internal and I can't move it to the external sd and it's kinda annoying can somebody help? Note: no rooting please

What Android version is running on your device? You might also wish to consult our app2sd tag-wiki.

Moving applications to your external SD card is not possible anymore because Android has changed i's way of managing storage. Your internal storage is now your SD card and your external one is a different, second SD card.
If you'd like to move apps to your external SD card then you have to manually change your external SD's mount point and swap it with the internal one.
Of course this requires you to root your phone.

Are you able to upgrade to Android >=6.0 or install a custom rom?
Since Android 6.0 is it possible to use the external SD card as internal storage. If you do so all data on it will be erased and the card will be repartitioned.
I' quite new to but I installed Resurrection Remix OS 3 weeks ago but running again into the storage limitation of my SII (I9100), I might used the wrong PIT (see Increase system partition size or Lanchon REPIT on xda).
Anyway as far as I understand, depending on your Android version, you can either use any of the apps such as AppMgr Pro III, Link2SD or App2SD what are able to partition and mount your extSD as internal storage, there is a tutorial on classroom.synonym.com (How to Partition Your SD Card in a Droid for APP2SD). May you have look on forums.androidcentral.com ([TUTORIAL] Everything you wanted to know about app2sd, ext3, ext4 partitions!!)
Using the >Android 6.0 in-build feature is a way more handy but that would imply that you install a custom rom but I couldn't find any for it, may you find one.
Regardless the outcome of this research, someone needs to answer the question how Android manage the internal Data and Media partition combined with the external partition before running again in any limitation and being able to utilise all 32 GB or 64 GB of the extSD. I found 2 well explained tutorials (#1 & #2) but both missing this detail.

Install Apps2SD from Play Store. Open the app. You will see the apps of your phone in 3 categories - In phone, In card and ROM. You can't move the app in the ROM category but you can move those in the Phone. Just long hold the app you want to move and from the option which pop-up, select Move to SD Card...
Hope this helps...

Poster is already using the App2SD functionality built into the OS, and apps are moving to the internal SD rather than the external SD.  This is due to the way the manufacturer sets up the device's internal storage (emulated SD card), which, in KitKat, blocks use of the external SD card for app storage.

i used 2gb memory card for 5 months in my HTC mobile, i have unmounted it and removed it safely to replace it with 16gb. but now when i try to connect the 2bg card to system and copy the images through adapter, they are lost...every other data is there except the Pics which i took using camera. please help me to recover that pics

If all the other data is there and you have not deleted the pictures, then the pictures must be there in the sdcard, unless someone else deleted them or moved them.
Try inserting the old sdcard into the phone and see if the phone displays your pictures. If it does, connect your phone to PC in camera mode and save all pictures to your PC.
If the phone also does not show the pictures, you can try the Dara recovery as suggested by Mr.Tech

Did you get your images back?

If you have not overwritten the data in the 2GB memory card, then you can recover the pics using "Recuva" in Windows PC. The software is available for free download online. Install the software, connect the adapter, select the drive through the application's interface and you will be able to recover the pics.

I assume (only assume, not sure) that those pictures are not on your external memory card but on your internal one (often referred as SD card).
If you haven't configured the camera to explicitly use your external SD card, all your pictures are on your phone's internal storage, independently of your external one.
Look at your pictures folder on your internal storage. There is a good chance that you missing pictures are there.

the camera storage was explicitly set to memory card which i removed.by the way the phone memory doesnt contain any pics

Well then you may follow Mr. Tech's advice.

@saikumar Though you might think so, check twice. You might have "2 SD cards" in your device: the external one you're already considering, and an "internal SD card" (also called "emulated"). Sometimes one needs to really take a closer look to see which one is meant by dialogs. You could use a file-manager on your device to verify. Also, opening the "Gallery" app could help: are the pictures still shown there? Then they're most likely stored on the "internal SD card".

If you have to many  pictures they show  blank  so you should  get a picture program that allows you to make stalks of your pictures to  save room and more  can be keep  on the phone that way

Reinstall "Google Play services"
I have deleted Google Play services on my Android cell phone. While trying to reinstall from google, I have "No Carrier Lenovo 860t) and can not install.
Please can you kindly help me on this, what is "no carrier" means and how to fix it ?
Thank you,
My phone : Lenovo 860t (China made)
Android 4.4.2 Kit Kat

Google Play Services has to be installed as a system application. Assuming you have properly uninstalled that application, you have to copy the .apk file back to where it should be (probably /system/app or /system/priv-app).
To that No Carrier thing: This just means that your device didn't send Google any Information about the carrier that you have and that you should use the normal, non carrier-specific store (There are different stores with some extra applications/different listings for specific countries and even carriers).

You can get back your Play Services, just by downloading Google Play Store, it will automatically download the Google Play Services, In many devices, only play store comes by default,not the play services, when you connect your google account,to play store, it will download the play services.

Missing Fedex cloud print on OnePlus w/ Androind 4.4.4 / T-Mobile
On my moto x 1st gen on T-Mobile I had an option when printing to print to a FedEx office. I'd get emailed a retrieval code to use at the store. On my oneplus I only have a save as PDF option in the print list (Google drive PDF viewer). I installed the FedEx app but that didn't add the printing option for FedEx.

I had a very similar issue.  I don't use Chrome on the desktop (Firefox) but I don't think that is relevant.  I am also using Nexus 5 with Android 5.0.1.  On my PC on Firefox I could see the Fedex printer listed along side the Google Drive printer but on my Nexus I could only see the Google Drive printer.  I fiddled with this for a while but I eventually got it to work.  I'm not totally sure what I did that fixed it but this what I tried:

Visited https://www.google.com/cloudprint/learn/ and clicked Try It Now
Select Print to Fedex Office and clicked the checkbox to agree to the terms (this only showed up once and maybe this was blocking it from showing up on Android?)
I didn't bother trying to print a test page to Fedex but I did go back print a test page using the Save to Google Drive option (again not sure if this was needed)
I verified that it showed up properly in my drive account
Finally I went back to my phone: Settings -> Printing -> Cloud Print.  Still only Google Drive printer listed (damn!).
But then I hit the back button and tapped Cloud Print once again (hey why not?) and all of a sudden the FedEx Office printer was listed!

So I'm not really sure what the deal is with this (definitely still beta I guess).  I think either agreeing to the terms on the PC and/or printing a test page kind of forced a refresh of cloud print settings down to my phone.  I wonder if clearing the data of the cloud print app would have a similar effect?  Anyways, I hope this helps a future person that got here via Google like I did...

Yay!!! Its working now :) Not sure if everything else was needed but in settings > printing > cloud print, i have a little slider to enable/disable the service. Fedex and google drive showed up after I toggled it.

Install Google Cloud Print from google play store. Then if I log in to the Cloud Print on my computer I see that I can print to the Fedex Office. I have not tried to print from my device, but I would assume I could pick this as a printer as well.

Fedex Information on Cloud Printing
Print to our self-service printers using your mobile device.

Send your print job to FedEx Office from your smartphone, tablet, PC, Mac® or other web-connected device using Google Cloud PrintTM, HP® ePrint or Breezy® or Canon® Forms & Print Services.
Receive a unique retrieval code that can be used in any of our convenient locations.
Enter your unique retrieval code. (Access by clicking on the link within your confirmation email or logging into Google Cloud Print and selecting your print job.)

Its already installed, ill try reinstalling...

If you log in to google cloud print from the browser/pc, do you see fedex as an options?

Reinstalling Google cloud print didn't help, its also missing from print options in chrome from my oneplus, ill check chrome desktop later.

Yep sure do have Print to FedEx office as an option when signed into Chrome desktop.

Adjust touch parameters
I have some problems with my touch in my lenovo phone. For example, when I touch in two places that the distance between them is less than 2 inches, the phone thinks that it's only one touch. To fix this and more problem with the touch, I need to know how to change some parametrs of the touch. So… Do you know where those params is stored or how to change them?
My phone (lenovo s8+) is rooted, and I have terminal emulator on it.

This is a hardware related problem. The touchscreen sends your system a touch event for every finger you touch it with. If the touchscreen's touch resolution is not that high, it will merge two touches to one.
You can't change the touch resolution of your touchscreen but it is possible to send custom touch events to the Android framework using some commands (I don't know them now but I used them and it is working. It is also similar to Windows' event system.)

Ignored 5.0 OTA update on nexus 4 now can't get it back
I ignored the 5.0 update when it came over the air a couple of months back because I didn't want it at that time, and now I do want to update, but it's nowhere to be found on my phone. I go to settings -> about phone -> system update but it just shows that "system is up to date" even when I click check for update. I'm running 4.4.4.
I know that I could go and manually do the update but it seems ridiculous that there is no way to get the OTA update back? I don't want to have to do a bunch of manual work.
Is there no way to do this?
Thanks,

Related: What is Google's OTA phase deployment strategy? & How can I force my Nexus One to upgrade to the official Gingerbread without waiting for the formal OTA update?

Alright but I've already gotten the OTA once and ignored it so I need to force it somehow to get it again. Clearly all phones already have the 5.0 OTA because that was like 2 months ago so waiting for another batch of roll-outs isn't going to work. And the second link is just manual.

Yes, but they are related to your question. I didn't say they were the answer, which is why I posted them as a comment, and didn't suggest to close this as a duplicate. Also related: Why can't I update my Nexus 4 to Lollipop?

I have found sources {1} {2} {3} that say doing the following can force an OTA, but YMMV.

Go to Settings > Apps
scroll down to Google Services Framework
select that app

Clear data
Clear cache
Force stop
Now go in to Settings > About > System Update and check for an update.

hmm I tried all the slightly different variations from your sources multiple times and it didn't work unfortunately. Thanks for the response though it was a good try.

Your only options then... Wait, or flash manually.

Sometimes a reboot (or power cycle) or two can trigger the update prompt again.
For Nexus owners, the Nexus Root Toolkit is indispensable.  It can do a whole lot more than you need, but... it can get the job done.
To flash an updated OS, choose to "flash stock" then make SURE you click "no wipe" if you want to ensure it doesn't erase your personal data.  You pick your target version, then it wipes the system partition and replaces it with the updated Android version (and then on first boot it'll do all sorts of upgrading to update your apps and data).

App not compatible anymore
I recently had to factory reset my phone, a Samsung GT-S5302 with Android 2.3.6. Now I'm trying to reinstall apps from Google Play store, but one of them says "your device is not compatible with this version" on the play store page.
This is nonsense, as it was working until yesterday, and it had been installed correctly and using the official way from play store months ago, on the same phone with the same Android version. Play store, seen from my PC, even still sees that app as installed, but at the same time says it's incompatible.
I contacted the user service of the app and they told me the app is compatible with android 2.3.3 onwards, therefore it's a Play problem. I also already tried to perform the steps suggested in the troubleshooting (resetting play's updates, download manager's cache and all that), with no results.

Try to download the apk from somewhere else (third-party stores, there are many). Then install it. If it's compatible, it will install without any issues.

I tried doing so, by simply moving the apk and tapping it. It opens with "app installer" or something similar, works for a few seconds and then happily says « √ App not installed.»

Then I might need to take a look at the log (adb logcat). There it will say what happens when you install the app and also where it fails.

How can I get it? I never used command line. Actually, there should be an "official" solution to this problem. If I can't find it, anyway, I can also go for unofficials.

There is no official or unofficial. The log will say where the installation fails. Easiest for you is to run the command pm install <.apk path>. Then it will give oyu a message about the success of the installation.

Trying to pm install it tells me:
/data/anr/traces.txt : permission denied
/data/log/dumpstate_sys_error.txt.gz.tmp : permission denied.
Unable to chmod /data/log/RR_LPON.p: Operation not permitted. Looks like something I should sudo.

traces is no problem. I'm curious what this other file is and why it has to be chmoded.

I have no clue.

Remove root via update
I want to remove the root, i.e. unroot the phone Nexus 4. The automatic factory image downloader using Nexus toolkit takes ages (for some reason). I also read somewhere that updating your rooted phone removes the root. So How do I update a rooted android in order to remove the root?

You simply flash a factory image. That overwrites the /system partition completely, effectively removing root.
For where to obtain those images, please take a look at Where can I find stock or custom ROMs for my Android device?

Using nexus root toolkit, there is an unroot button, use that, then do a factory reset (and/or a reflash) if you want to.
After you have unrooted press lock, to lock the bootloader.

How I can reverse-tether my tablet using my phone’s mobile broadband with bluetooth DUN, without rooting?
I have a phone which run java for the J2ME platform not android ones.
When I pair it with my laptop, I can use the phone to connect internet using mobile broadband connection (I pick my provider in a list on the laptop to autocomplete the parameters).
However when I pair it on my Samsung Galaxy tab S, I don't have this option, even when there is no Wi-Fi access point.
There are lot of apps to convert you android phone into a server for this. But I own a tablet with android 5 (only Wi-Fi and bluetooth connection), and I would like to use my classic mobile phone as access point over bluetooth. I know how to configure the phone since I already use it on my Linux laptop. But I don’t know how to use my tablet as a DUN client, and I couldn’t find an app on the play store for that.
For those who still don’t what is beeing asked here, here’s a tutorial I use for a non wizard tethering on Debian (I couldn’t find a android equivalent).
So, how I can connect Samsung galaxy tab S 8.4 to internet over bluetooth with my mobile phone's connection?
Update :
Here’s my provider parameters in my case :
dial-up number value : "*99#"
APN value : "Free"
Authentication method : Store
Username value : "Free"
Password value : "Free"
DUN channel value : "0"
Connection method : GPRS
PIN method : Store
PIN value : null
Provider proxy address value : "212.27.40.225"
Provider proxy port value : "80"
But on most OS, (for laptop, including old windows) you just get a country selector, then you pick-up your mobile provider in a list and the connection parameters are filled up for you.
Note: As the device is still new I want to keep the long time warranty option.
BlueVPN+ seems to indirectly allow what I need without rooting, but the program is not free.

Sum up : I often use bluetooth-tethering trough my phone’s connection on my laptop and I would like to do the same with my tablet. The aim is to access my e-mails when there is no Wi-Fi access point.

possible duplicate of Can I reverse tether my Android device to my phone using Bluetooth PAN or DUN?

@RyanConrad : I don’t think a rooted answer is enough to mark the answer as a duplicate. Especially in that case.

Ok, that's why it's called a 'possible duplicate', either way it is related. Here is another is very similar to your issue as well: TCP/IP tethering over Bluetooth

While waiting for an answer to your question, you should also take a look at other questions with similar issues and see if any of those help you.

@RyanConrad : No, because there is the connection type in more of bluetooth-tethering. It allowed me to view the review the existing answers quickly : http://android.stackexchange.com/search?q=%5Breverse-tether%5D+bluetooth+is%3Aquestion+DUN http://android.stackexchange.com/search?q=%5Breverse-tether%5D+bluetooth+is%3Aquestion+mobile+broadband http://android.stackexchange.com/search?q=%5Breverse-tether%5D+bluetooth+is%3Aquestion+GPRS . It also seems the answer for rooted phones will not work for me, because it doesn’t ask providers parameters, nor provider brand name.

This question is off-topic here. This is not an android related question, every answer is going to be "wrong". This site is for android related questions.

@RyanConrad : Either You or I didn’t understand : I’m not asking how to set up my phone for tethering, since I already know it. I want my android device to use the non android phone’s built-in GPRS modem (which is something most 2G only GSM only phones have) via bluetooth. It work by using this service and the following official service classes : 0x1103 0x1204 0x112D.

Also Sighh, What a shame for android that peoples don’t understand. when pairing the phone with a computer makes the OS propose to use it as an INTERNET access immediately and where the configuration is just matter of picking up the provider in a list :-(. (This works with GNOME KDE and windows up to XP).

So I was doing a bit of research on this.
TLDR; You will not be able to use your phone's GSM to connect your tablet to the internet.
In order for your Android device to be able to connect to another device, via bluetooth, to get an internet connection, you need an android device that supports DUN (Dial-up Networking) or PAN (Personal Area Networking). Which most android devices do support. You also need the "host" device to also support DUN. Your phone, on the other hand, does not support DUN nor does it support PAN.
Here are the bluetooth profiles that your phone supports:

Bluetooth Profiles:

A2DP
AVRCP
BPP
FTP
GAP
Handsfree
Headset
HFP
HSP
SAP

The reason that you are able to get your laptop to tether via bluetooth with your device is because Windows supports tethering via SPP.
From Wikipedia:

Note : The Windows XP/Vista Windows Vista/Windows 7 Bluetooth stack supports the following Bluetooth profiles natively: PANU, SPP, DUN, HID, HCRP.

While Android does have support for SPP, it does not support tethering via SPP. This is only supported via DUN/PAN. There is an active issue around this that is listed as assigned to a developer but has had no activity since June 23rd 2013.

I bought the Nexus 7 3G as a professional development tool to make bluetooth applications but from what I see, I'm stuck with an expensive paper weight. The SPP profile is used by many companies to connect there devices (robots, OBDII scanners, Microcontrollers, dataloggers.. e.t.c) to tablets. This protocol should have worked with the Nexus 7 but does not.
It did not work with android 4.2.1 and does not work with android 4.2.2. It used to work with android 4.1.2.
Not everyone can downgrade to 4.1.2 since it is not available to all devices.
Now we all have to wait until android 5 comes out, but I do not think this will be fixed since google does not take us seriously.
Don't you guys tests your products before you market them or do you just let the end user do the testing for you?

note : since I upgraded to Windows XP service pack 2, I can't use windows anymore for this (but that's why I use KDE) because becuase higher version of Windows only support classic modem dial-up, and try to use the phone modem as a classic 56k modem (non GPRS bluetooth modem). I also runnedsdptoolon my phone and it appear you where wrong on the supported bluetooth profiles (the hex number coressponding to DUN appear in the list). DUN also reaquie a supplementary autorisation (which my phone prompt before each acess for each device in more of pairing).

I also successfully connected to INTERNET, with blueVPN, but there is an issue in android 4.4 kitcat which makes you need to create the connection while being already connected to a Wi-Fi AP. When the connection was established it prompted me to buy blueVPN+.

Your phone, on the other hand, does not support DUN nor does it support PAN. is wrong. When I pair my phone with my laptop The phone prompt me if I allow the laptop to use DUN0. Most IOS and android devices doesn’t support BT/DUN (this is something you can check by listing the bluetooth profiles of the device). I can no longer use windows for pairing as XPSP2 and higher try to use the modem as a regular one instead of GPRS.

I finally discovered my device support PAN (reverse tethering over bluetooth work with my laptop) but not DUN and my phone support DUN but not PAN.

Install and use easytether. I use this on a wide range of devices across multiple operation systems.

Welcome to Android Enthusiasts. You should consider linking to easyteather, and explain exactly how it would solve the question.

@RyanConrad the answer is simply wrong.

You didn't read my question (I put links to my phone model). Your software doesn't use the standard bluetooth method, so it require custom software on android and windows. My phone is a java phone, but not an android phone, it can't run software as long it is not a plain jar file.

It doesn't matter if its right. We have standards for answers and i was asking that they be followed. It might not be the answer for you, but it may help someone else.

If your phone is not an android phone, your question does not belong here.

@RyanConrad : It is on topic because I want to reverse-tether, on my android tablet (Only Wi-Fi and bluetooth) to a non android phone (using the service defined by the bluetooth standard). I never wanted to reverse-tether my phone, but I need to tether using it.

Is it possible to set up a Google account for Gmail only?
As the title says, is it possible to setup a Google account on an Android device in a way that it will only be used to access Gmail?
I have several apps from the big G installed on my phone (obviously, I dare say), namely Gmail, Play store, Maps, Keep, and so on.
I also have three different Google accounts, the main purpose of this is the need of having distinct email addresses. Let's call "A" the main account (the one that I also use for other Google services like Play Store,  Contacts, Calendar and so on) and "B" & "C" the remaining two, only used for email.
I'd like to setup "B" & "C" so that they are only used with Gmail app, and won't pop up in every other Google app, where they are not needed nor wanted. Is it possible to do so?
I have already set them to just sync with Gmail and not other things like contacts and calendars, but that's not what I'd like to accomplish. I want them out of the way where they are not needed.

But if you do as you've said you have (uncheck what you don't want synced) then they are pretty much out of the way. you wont get notifications, you won't see extra content. You wont seen anything extra until you manually request it. By default every app will then use you're one account that you've set up to be your main account. I use two accounts on my phone with selected items set to sync and other not - I've never had an issue with the secondary account getting in the way.

I found a workaround for my problem that works splendidly.
After having installed the latest version of the Gmail App, I have discovered that when I go to Settings > Account > Add account, I can configure a generic email address (i.e. not necessarily a Gmail one) to be used with the said App. It supports both IMAP and POP3 protocols.

(sorry for the Italian, but it should be understandable nonetheless).
I suppose that this feature was meant to use email addresses from other providers inside the Gmail App, but it will accept any email configuration, even a Gmail one.
So I selected IMAP for my second and third email addresses, and now I can access those accounts just for Gmail; this way they won't be able to get in they way on other Apps.
On Google Help Center I have found the settings required to configure an IMAP account on an external client, which I have used. I'm reporting them here for completeness.

To configure the 'Email' app on an Android device for access to Gmail,
  just follow the steps below:
1. Enable IMAP in your Gmail settings.
2. Open the Email application.
3. Tap Menu and the Settings
4. In the top corner, tap  select Next to get started with setup.
5. Enter your full Gmail address and password, then select Next.
6. On the next screen, you can give the account a nickname and choose the name to display on your outgoing messages. Tap Done.

And you're done. You can verify your settings from the Inbox view by
  tapping Menu, select Account and then scroll to Server settings.
Incoming settings
IMAP server: imap.gmail.com
Port: 993
Security type: SSL (always)

Outgoing settings
SMTP server: smtp.gmail.com
Port: 465
Security type: SSL (always)

Now that your account is set up, learn how actions in your client sync
  with Gmail.

Amazing. I had no idea that this was possible in the GMail app. This should be the first answer! :)

While you add the Google account or even afterwards (from account settings), you can select the content and services to sync. You can select only Gmail, leaving alone all the other services you don't want like Google+, drive, sheets, docs etc.
There's no need to setup a third party email client. All (most) Google apps are aware of this functionality and will work correctly.

Thanks, that's how I already did, but I wanted those accounts to access only Gmail and not other Apps, not just to have them out of sync. It's not the real solution but it works as a workaround anyway :)

This not necesserly Android-related, but you mentioned you use those accounts only for emailing. Please see this and this link.
It is possible to send and receive mails from different addresses using only master account and therefore you would have no need to add separate accounts to your Android device.

Just use AOSP/alternative email client for the second account instead of adding another account to your phone just to use it for mail. You can also forward your mails automatically to your main account and label it as you wish.

As you have mentioned you are using Kit-Kat, just open alternative email client as user87790 has said.It just comes as separate app named as Email. Open the app. Select add new from the bottom left corner with add new mark(Plus mark with pencil). Add new account enter your account details. Add both the accounts b and c in the same way you enter the password with email in Gmail app. If you want to see emails from  B an C separately just select the account from drop down. Or if you want to see everything from both the accounts select Combined view from drop down.

Using "IMAP email account" instead of "Google Account" works great if email is the only thing you need.

It is very well possible. Sign in with that particular account only from gmail app and it will not sync with anything else.

Use the F-Droid repository to install K-9 Mail. (https://f-droid.org/repository/browse/?fdid=com.fsck.k9). This way you do not have to use a Google account to install a mail application, and while you access GMail through the non-Google app, you can also take advantage of additional features of K-9 such as OpenPGP support (https://f-droid.org/repository/browse/?fdid=org.thialfihar.android.apg).

@samsung your comment is inaccurate. Firstly a Google account is the same as a gmail account. Secondly and most importantly the OP is looking to use the additional Google accounts for gmail ONLY, not the other way round as you've stated.

On Android, what is a "blue screen", and what should you do about it?
Some Android users complain about seeing a "blue screen", also known as a "blue screen of death" or "BSOD". They add that their device has become unresponsive.
(Here is one example, including a photograph of the affected device. Here is another example.)
On Android, what is a "blue screen", and what should you do about it?

This thread has been viewed more than 2,700 times.  As well, if you do a Google search for [ android blue screen ], it's the top hit.  I'm surprised that I'm the only person who has contributed to the thread.  I encourage my fellow Android.SE site members to edit and improve the answer.

I experienced the same thing. The only other link I found related to my phone (Samsung Galaxy S4 Value Edition) was this one: http://forums.androidcentral.com/samsung-galaxy-s4/629648-my-samsung-galaxy-s4-shows-often-shows-bright-blue-screen-restarts-its-own-after-restart-why.html
Could write more about it but this is not the place. My solution was: Official Samsung service center took out the defective system board and put in a new one (luckily for free since it was still in warranty for another 14 days).
Protip: Do regular phone backups. System board fried = you lose everything.

What is a "blue screen"?
Certain Android devices sometimes become unresponsive and display a plain bright blue screen with no text on it. See photo.
What should be done?
(This answer is based on what someone on IRC once told me.)
If you only ever see a blue screen once or twice a month, ignore the problem and restart your phone when it happens.
If you see so many blue screens that it's worth the effort involved in troubleshooting, then it's time to dig for the cause of the problem. Here's how.
First of all, grab a pen and paper, and make a note of the exact time when the blue screen appeared. Hours, minutes, and seconds. This will come in handy if you decide to run adb logcat later.
If you have adb (the Android Debug Bridge) installed on your computer, and if you have enabled "USB debugging" on your device, then adb logcat might (or might not) provide you with some clues as to why the problem happened. In fact, I've always found that adb logcat works fine even while the blue screen is still showing.
(If you aren't using a very recent version of Android, then your logs will lack timestamps. In such a situation, use adb logcat -v threadtime to show the timestamps.)
If you experience a blue screen and want to make it go away, reboot your device. If you have adb installed on your computer and working, then open up an adb shell and reboot the phone the graceful way. If the graceful way doesn't work, choose the semi-graceful way by using the adb reboot command. If you don't have adb installed, do an unsafe shutdown by holding down your device's power button for ten seconds. If that still doesn't work, pull the battery out.
But why did the blue screen happen?
I don't know.
You should post a separate question. Tell us the hour, minute, and second when the blue screen came up. Provide us with all the log entries (from each of the several logs which adb logcat dumps out) starting from 30 seconds before the blue screen appeared, right through to 30 seconds after. Let us know approximately how many times the problem has happened. (Dozens in the past year? Hundreds in the past month?) Also, tell us whether or not you have figured out a set of steps to reproduce the problem on demand. Finally, please do provide us with all other relevant details.
What should be done after the device has been restarted?
You should make sure that USB debugging is enabled. This will make sure you can use adb in the future. For instructions, see the PhoneArena article entitled "How to enable USB debugging on Android". You should only ever have to do this once.

SD card readers don't work via USB OTG but USB thumb drives do, any ideas?
I have a Huawei Ascend G6 LTE (G6-L22) and bought a little USB OTG cable so I could read full sized SD cards while out and about.
Only, it doesn't work, on either of the SD card readers I've tried - both of them small USB2 based readers.
When I plug in USB thumb drives to the adapter, they work fine and I can browse files and photos.  But no go on the card readers.
What will happen is the phone either doesn't see the drive at all, or it sees it momentarily then it disappears with a "your SD card was disconnected" notification.  The LED on the card reader lights up when you first plug it in, but then goes into a fast blinking pattern which seems to indicate a problem.
Any ideas?  I wouldn't have thought an SD card reader would exceed the normal power supplied via USB OTG ports, and its LED lights up.  Could the phone just not have a driver that supports card readers?
Edit: the filesystem on the SD card was FAT32, as it was a 16GB card I use in my DSLR.  I use the stock ROM but am rooted.

Was just about to ask the same question.

I believe that the problem is lack of power. Your phone doesn't deliver enough power to the card reader. I would suggest using the same kind of cable you used to need when connecting an external hard disk using USB. It has one contact for the hard disk (card reader in your case), one for the phone and one for extra power (use a separate USB charger/adapter).  That should solve the power problem.
I don't know where one can find this kind of cable in your part of the world. They should be fairly easy to find though.
If this doesn't work I would use the Googles ADB developer tool to check the logs on the phone to see if there are any error messages that could help.
Good luck!

Without having the same phone, but playing around with OTG, the problem that you are describe seems to be because of the lack of power. Try using an external source of power for your USB card reader before connecting it to the phone. Maybe rooting the phone and searching through the file, you will find the option to output more power to the USB port of your phone.Once I was able to use (on a 4 different devices when I had a USB hub getting power from a power socket. Last but not least maybe this card drive can't be recognised by your phone because of the lack of drivers.

You tried different readers and each exhibits the same problem. Also try a different card by a different manufacturer with the hope it draws less power.

try another card reader like this https://www.amazon.com/dp/B06XBB4KJ3/ref=olp_product_details?_encoding=UTF8&me=

Trigger re-read(or update) of (System)App database
System apps or apps in general are capable of storing information within a database. My problem is now: for example the Launcher app does store settings like the amount of apps and their position on the homescreen, widgets etc. into a database on the data partition.
These settings are usually just read from the database again even if there is a new Launcher app replacement with different settings for the homescreen.
My question is now: Is there any method(via shell) to trigger an update or re-read of this apps database, so that the new values from the new Launcher replacement are taken into account without just deleting the whole database or messing around with the current database?

Not sure, but even Lollipop's stock launcher and Google Now Launcher uses different database (or other data storage). So, unless you're sure both launchers use same database, then there might be a possibility to update/overwrite the DB, but it will come to effect when the launcher reads the DB again.

the launcher is just an example for better understanding what I actually mean. Iam talking in general about a method how to trigger such an update for the specific database of an app. The replaced apps are using the same package and are built from the same source just with different configurations.

Then, as long as the database file is there, the app will read it when it needs to read it. There is no need to force read/update from outside (well, I'm not even sure if it's possible). It should be controlled within the app itself. Apologize if I still couldn't grasp the idea, maybe other readers might have solution for this.

Just to archive the right answer from Andrew's comment:

Then, as long as the database file is there, the app will read it when
  it needs to read it. There is no need to force read/update from
  outside (well, I'm not even sure if it's possible). It should be
  controlled within the app itself. Apologize if I still couldn't grasp

I was confused about how these databases are handled. It is exactly as Andrew wrote: It depends on the actual implementation when and how the database is re-read.

Is factory reset neccessary when updating cyanogenMod?
I have rooted my phone and have TWRP installed.
I am updating CyanogenMod 11 to 12.
Do I need to do a factory reset/ Clear data partition to proceed or can I do without it?

Well, I would say its not like Kind of a thing which needs to be done inorder to proceed but rather than its like it's always advised to make sure that you don't ran onto trouble as sometimes because of the junk folder you ended up in something where you don't want to be !

Yes, it is always recommended to do an factory reset and wipe cache data after every update or change of firmware to avoid problems.
You will lose all your data anyway so right after flash your new firmware, reboot the phone. You don't say your phone so just do as usual do the factory reset wipe cache reboot it again then done wouldn't spend more than 5 minutes.

View log files on rooted Nexus 9
I'd like to check some log files of a app I've downloaded from the browser.
I rooted my device already and saw in the "SuperSU"-App a Logs-Tab. How can/do I use that? Or do I have to do something more?
Thank you

Download the app called CatLog - LogCAt reader it can read all your logs and it's open source

This answer might be helpful if you add a link to the app you're recommending.

True, but I found it easy on the PlayStore

Yeah it's on playstore and it's easy to find on playstore i don't have the time to search for the link myself if someone can edit and add it i will accept also i forgot to say that the logs you see on SuperSu is the logs from apps that required root access only not other logs

Problem PC stopped seeing S4
My S4 has suddenly stopped to connect to any computer. I tried with 3 different cables and 2 PC's with win7. I can't see it as a hard-drive. I can't see it in the device manager either (should I)?
Any help would be welcome.
Many thanks!

What about connecting with Kies? Does that work?

Uninstall the drivers from Samsung and download and install then again on your PC this seems to be an driver problem. If this not resolve your problem come back and I can suggest other options.
Does your phone recharge when plugged in?
Any sound on your PC when you connect or any notification on your phone about being connected via USB?

Thank you for your answer.
The phone is charging and there is a beep when I connect it to the pc. I tried to connect it to other pc's where no Android were ever connected and I couldn't see it ether. Tried to reinstall the driver but nothing yet.

Cannot receive files using Bluetooth on Karbonn Android One
I have Karbonn Android One. It is unable to receive files via Bluetooth from any Android device, but there is no problem with sending files to every device.
I could not understand what's the problem. How can I receive files using Bluetooth?

Try resetting your phone... This usually works. Remember to take a backup.

Try resetting the phone? because the phone wont receive files via bluetooth? seems a bit extreme, don't you think? Wipe the entire phone and have to set everything back up.

Wifi wont work in Samsung galaxy 3 even after a hard reset
I have a samsung galaxy s3 which was in excellent condition when I sold it.  After 2 weeks, the buyer wanted a return, so, I got the phone back. Somehow, the wifi is not working. When I look at the firmware, it says 4.4.2 which believe is kit kat. It seems to me like he tried to hack it and now the wifi wont work. Plus, who knows which other program he altered? I end up paying him and end up with a phone I can't even use. Please help me. I followed the hard reset and it still wont fix the problem...:(

Android 4.4.2 (Kitkat) was not officially released by Samsung for the Galaxy SIII.
You can search at SamMobile for your SIII (GT-I9300) and download the latest official firmware. (registration required but I can give you the links too, if you don't like to register there)
Then flash it using Odin (or similar) to get your stock firmware back.

A private sale is free from any warranty by the seller, so you didn't even have to accept the return (in the EU at least).

Curious.  I have 4.4.2 on my S3 via Verizon.  Does your answer refer to non-US only?

The S3 by Verizon is not the I9300/international version. The international one has 1GB of RAM, only Android 4.3 and no 4G.

Ok, so, how could you tell that's what the OP has from the problem description?

He said that the buyer tried to hack it, so I assumed Android 4.4.2 is not the version that was on it before.

My best guess is going to involve reflashing the ROM by using ODIN. There is a website that has all Samsung firmwares in zip files available for download, just get one and find instructions to use ODIN to flash it. Just be very careful, you could make matters much worse if you don't use a compatible ROM or don't follow instructions perfectly.
If that doesn't work, then it must be a hardware problem. In that case, there's not much I can recommend... Perhaps taking the back off and screws out and checking that everything is connected properly.

Google shows wrong country
Play Google does not show apps for my country. I visited another country and came back and store is stuck to that country, I tried clearing data, removing my addresses and cards from Google wallet (and adding them again), I have made purchases before and now when I try to purchase it show no availability for my country. Any help would be appreciated.
tinder gives next error: labResult: Error checking for billing v3 support. (response: 3:Billing unavailable)
Edit: there is restriction for every app which is paid or has in app purchases, country is Georgia

@bmdixon No, it's not, I have seen that thread and done suggested, but no help

Have you tried buying an app which has no country restrictions? Just chose any and buy it (and optionally return it within the 2h refund window). AFAIK that's the last trigger Google Wallet needs to update your location (accessing your credit card, or whatever). Shortly thereafter, it should find you again in the country you're in now.

@Izzy there are no apps that can be purchasable in my play store

That's pretty strange. Not all apps are "regionally restricted" – except for the point that some regions cannot buy any apps at all. Did that apply to "that country" (you see, it might help to explicitely name involved countries here)?

@Izzy yes there is restriction for every app which is paid or has in app purchases, country is Georgia

So that's a completely different case then: if playstore purchases are generally not available in your country, there's no "official way" you can go about that. In this case, what applies is rather How can I circumvent regional restrictions in Google's Play Store?

Use the link that Izzy provided. By following one of the answers from that link and you should be up and running. I'm in the US, but I have used the first answer to allow me to download apps that aren't available in US.

Ringtone and vibration not working on Nexus 5 (Android 5.0.1)
Ringtones and vibration stop working on my Nexus 5 (using Android 5.0.1) when receiving a call. There were working before, but I don't know why the ringtone and vibration just stop.
I tried different things: restarting the phone, updating the software, changing the setting ringtones, turning off-on these settings for both ringtones and vibration, etc.
Can anybody help me?

Sorry. I just found the problem. It seems pretty obvious but I coudnt found any help in the web.... The point is that when you increase the volumen of the ringtone (with the left key of the phone) 3 different options shows up. In my case te option "priority" was on. It should be "all" !

Welcome to the Android Enthusiasts! On SE sites, it's perfectly fine to answer your own question – but answers should be posted as answers, not as part of the question-post or a comment to it. Mind moving it to a separate answer? Thanks in advance!

I had this problem and it was so annoying, because I missed all the important call due to this error or setting. I didn't change this setting and only Nexus phone know how it changed this setting.
Please follow the steps below and it will start ringing.

Press Volume Up key on the the phone.
Select the option "Indefinitely"
Select the Settings icon (the wheel icon)
Under "Priority interruptions" section, enable Calls.

Enjoy, no more missing calls

Had the same problem. Please follow the below steps:

Press on volume key (up or down)
On the Gray menu select None and Indefinitely
Exit the menu by clicking on the main screen
Press on volume key again
Select All.

It should work now.

I had the same issue but opened the back panel and replaced it back again. I think it's because the vibrator is on the back panel. Maybe a loose connection could also cause this.
Before removing the back, remember to switch off your mobile.

How can i undo "Remove bluetooth device" from kitkat?
Before i was able to connect my moto X with my PC windows 7 64bits via generic bluetooth dongle. But i removed the pairing from my moto x and now its undetectable by the PC. Every time i turn on bluetooth on the PC and on the phone , then a turn on bluetooth on the phone and make sure its visible for all devices, its not detecting the pc and vice versa.
So, how can i undo the unpairing and make my phone and pc connect again ?
EDIT: I tryied to remove the registry key ( HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys ) from windows registry but no luck.

Looks like your issue is more on the PC side. If you don't get an answer here, you may want to try asking over on SuperUser.

Make sure your both PC and PHONE are close to each other and the both Bluetooth are turned on and visible for all devices on both then go to your phone and search for devices and see if your PC will appear then try to pair then again.
There is no such a thing as 'undo pairing" you just need to pair them again.
Try that it should work usually if not check if there is any problem with your bluetooth on your pc in device manager.

Sure, they are in close enough. But when i said "undo unpairing" i meant "undo forget device"

Still the same you just need to pair them again probably one of your devices is not visible for all ? Try going to a photo and share it via bluetooth see if your pc will appear

Maybe i messed up my MS bluetooth stack when i removed the registry keys, and now how to undo this ? Is there a way to reinstall/ restore the windows bluetooth stack back?

Yes go to windows update and check for updates if you let it search for drives or google for your hardware + driver

thank you, my problem is not solved yet but im going to try this !

On my Samsung S5 how do i get my emails to stay in my in box until i delete them
i set up my email on my samsung s5 and i get emails but they disappear after about 15 minutes and there not in my in box, junk, or trash bins. In my settings i have delete emails from server set at never. how do i get the emails to stay in my inbox until i delete them?

Make sure your Email account is set up as IMAP (not POP3).
In theory POP3 downloads a single copy of the email to the device that requests it. In practive, i've noticed the same issue you described whereby Emails seem to disappear.
IMAP syncs a copy of the Email from the server to your device to ensure you can view the same mail on multiple devices.

Restore S-Memo files
A few days ago my Samsung Galaxy S4 asked to uodate the Samsung Account application which I accepted. After that all me S-Memo files are gone. They aren't in me SD-Card/S-Memo folder. And when I open S-Memo and choose import I can't choose Samsung account. The Memo's are still on my Samsung backup account. When I go to settings/account/samsung/used storage I see 2.85 mb of S-Memo files. When I click on that it asks me which files I want to delete but I don't want to delete them. I want them back. When I go to the account tab in settings again there's a option called cloud with which I can restore files from the Samsung cloud but I only can choose between, logfiles, mms, sms and wallpapers. I definitely need the memo files back. Does anybody knows how I can get them back from the Samsung server. Luckily they aren't completely lost.
Thanks in advance,

I know this is an old question but i just updated my phone software and lost my SMemo's. Dont know how many other people would still be updating old software but in any case, here's where I found them on my phone:
My Files>Application>SMemo>Switcher
Also, when i connected my laptop to the phone they could be found in:
Phone>Application>SMemo>Switcher

Galaxy S3 keeps switching wifi settings to use a manual proxy
I get no internet connection message.  I go to wifi settings, and something has changed it to use a manual proxy setting.  I don't have a proxy server.  it's a home network.  I switch it to no proxy, save, and all is good for about a minute, maybe less.  I look at network settings, and boom, it's using a manual proxy again.  How do I stop this?

There's either an app that's controlling this setting, or malware. On Windows behavior like this is caused by malware 9 out of 10 times, but on Android I'd suspect that some app is the likely culprit.
For a list of apps with permissions to monkey around with your settings, go to Settings→Security→Device Administrators. Anything listed there that has a checked box on the right has permissions to control settings on your device. See if there is anything in the list that stands out, such as security software or network-related software. Try to isolate which one is the culprit by unchecking the enabled device administrators one at a time and then checking whether changes you make to the proxy settings stick.

I did a quick search on this and I'm seeing that Kaspersky Mobile Security comes up frequently as an app that makes changes to the WiFi proxy settings revert to "Manual" with a localhost IP address (127.0.0.1). Is that the IP address you're seeing, and do you have Kaspersky Mobile Security installed?
According to this thread in the Kaspersky support forums, there was a known bug related to this issue in version 10.4.45. A Kaspersky rep said it would be fixed in the next version in June 2013, but according to this thread in the Vodafone forums there was still an issue with this in a later version:

Thanks for your suggestions guys, I think I have solved this one.  I found other people were having the same issue who were using Kaspersky Mobile Security.  I've just uninstalled it  (version 10.4.47) and not only has this issue completely gone, another weird issue I was having where the WiFi connection took 3 - 4 attempts before it settled on a connection has also gone. Happy bunny.
I need an internet security app though so I may try that Lookout app you mentioned.

I'm not familiar with Kaspersky Mobile Security, so I can't tell you whether that means that the behavior of changing proxy settings is itself a bug that has not been fixed, or that there used to be a more specific bug with this feature but the behavior in general is part of the functionality of the app. However, I can tell you that I've been using Lookout for about a year and haven't had this or any other problem with it.

Another app was my thought too. I'm just not sure whether it requires device-admin to do that (a dev might be able to tell), though it sounds right to me. I initially thought of the CHANGE_WIFI_STATE or WRITE_SECURE_SETTINGS permissions (which can't hurt to check for as well), but at least for the former I'm not sure if that could do a thing like that.

Only one head phone (Right) working on my andrioid razor
Has anyone had this issue on their android where only one headphone is playing music. I use Pandora and I already did a factory reset and still nothing. Anyone have any other ideas?>
Thank you

Have you tried the headphone on other device (e.g. PC)? If it also occurs there, then the problem is on the headphone (e.g. the cable is cut internally). Otherwise, we still can't pin-point the cause without additional info.

Try another headphone ? It's very likely the one you have its defective

I hard bricked my phone, now what?
So today I hard bricked my week old Iocean X8, as soon as my phone arrived it came stock with a jellybean ROM so I flashed it to the KitKat ROM provided by Iocean which all worked fine but I decided I wanted root access so then I attempted to flash to the super user ROM and that's when everything went downhill.
As far as my knowledge goes a hard brick is were the phone will not turn on and the PC will not recognize the phone. I also do not believe Iocean X8's come with a recovery mode.
I have sent an email to Iocean asking for the next steps to take but they are taking a little while to reply.
Have the Android Enthusiasts got any suggestions?

What does the phone do? Hard bricking usually happens when you flash a bad bootloader. If you can get to fastboot or recovery on the phone you are only "soft-bricked".

Can you turn on your phone using special sequence of buttons  like power + middle button + down volume ? I don't know what is for your device but you can google tjat quickly...see if you can turn on in download or recovery mode. If yes try a factory reset and wipe cache data and reboot.
If that not work then is time to flash your stock firmware again on it you need odin and the stock firmware image you can search on xda developers forum for your device both the stock firmware and the guide on how to execute.If you not find on xda developers forum then try google but be careful don't download the first thing you see try to get the firmware atleast from a trusted source.
Your phone is not hard bricked it is soft bricked you bricked the software not the hardware but stay calm the above steps if done right should make your phone reboot again.
You will lose all your data if you want do to a backup you can try an backup via ADB you can google for "backup via adb android" follow all the steps with calm and carefully and you can make your phone reboot again without lose nothing.

You could try install a RUU rom,bring the device back to stock,as explained by @freedom ,RUU is the stock rom, you must search for your device and xda dev should have working,trustable links for ruu rom/stock. then simply dont try gain root, if there is a reason for root, sure, but  really you had a rom custom in there,you really didnt need root.
How to get there?
try hold power button+vol down , this should allow you to enter usb mode, try until you get there,because you must use recovery mode to fix problem completely, hence it is classed as a soft brick. Goodluck.

How to access app menu without app button?
I have a Samsung Galaxy S5 and my app menu button is broken.  (I accidentally destroyed it while replacing the screen.)
Is there any other way to access the app menu or view a list of running apps, switch between them, close unneeded running applications?

BUILD.PROP SOFTKEYS (ROOT)
If you have root, you can emulate soft keys, like the ones on the Nexus and other devices, by modifying the build.prop file. To do this you will need root. There are many guides to rooting your device, such as this one on XDA.
After you are rooted, install an app like Build Prop Editor. Change (or add) the following key: qemu.hw.mainkeys=0 (add a key named qemu.hw.mainkeys and set the value to 0.) Be careful and make sure that you have typed it exactly as shown. After this, you will need to hard reboot your phone. Power off your device (or remove the battery, not recommended) and then turn it back on. Note: For build.prop edits, you will need a hard reboot; a soft reboot will not apply the changes to the build.prop file.

THIRD PARTY APP
If you do not wish to root, you can install an app like Handy Soft Keys. Please note that this may affect performance, battery, and data usage negatively, as it is not native to Android like the build.prop edit.

Great, I got the app installed and it works, thanks!

Can't find some apps in Play Store while others don't work
After I factory reset my Samsung Galaxy S4, some apps were reinstalled easily, while others didn't work as they used, and some can't be found in Play Store (YouTube Downloader). All Music Downloader won't work. I had Simple MP3 Downloader before, now it doesn't work.
Why can't I find them anymore, and why some of them also don't work anymore?

Some apps may be restricted to some countries, or they may have been removed by Google. Try to browse Play Store using browser to confirm if the apps are still there. Regarding "music downloader won't work", it's unclear what you meant.

TubeMate (and all similar YouTube video downloaders) were removed from the Play Store for violating Google's Terms and Conditions. Simple MP3 Downloader was also removed for this reason. You probably downloaded the apps before they were removed from the Play Store, so that is why you had them before.
You can still install those two apps to your phone from manually installing the .apk files for TubeMate and Simple MP3 Downloader.

Unable to unlock/turn on Nexus 4 : Lollipop 5.0.1
I am running Android 5.0.1 on my Nexus 4. This has started happening recently. Whenever my phone is locked, and I try to unlock, nothing happens on pressing the power button. Initially I thought my battery was getting drained to zero and phone was shutting down, but that's not the case. I need to long press power button and restart my phone forcefully. Some observations are:

This issue was not there when I was on 5.0.0.
Also I am finding that this is happening when I play a game and then close the game and leave the phone. Most recently, I have been playing Swish and Drift Zone.
However, even after uninstalling the issue persists.

Any suggestions/references to overcome this issue are welcome. TIA.

I have the same problem with 5.0.0 on a Nexus 4. It crashed once in the middle of the night and once when the alarm was supposed to ring. So it's not related to a game for me.

Coincidentally, I have been a victim of the exactly similar situation :)

I have experienced many problems with Android 5 on both my Nexus 4 and my wife's exactly identical Nexus 4. Strangely enough, both phones experienced slightly different problems. The main issue with my own phone was WiFi - it simply did not work except for a few hour period after rebooting.
I have not experienced this issue since switching to Cyanogenmod using the instructions from their Wiki:
http://wiki.cyanogenmod.org/w/Install_CM_for_mako
My wife's phone has experienced the same exact problem as you. Sometimes it won't show anything on the screen, won't wake up. After rebooting everything is fine. This occurs even when plugged in and fully 100% recharged.
So my solution is to get away from Android 5 Lollipop. I don't know how to downgrade to an older version of Android, but moving to Cyanogenmod has fixed my own phone and I will be switching my wife over probably this evening.

Can a flashed rom leave behind artifacts?
I found a few "unofficial" Lollipop ROMS floating around the internet.
I don't know how reliable are they, or how many viruses are there.
All I want to do is to play with it a little. I'm thinking of making an NANDROID backup, flashing the rom, playing with it a little (with no private information placed there), and restoring the NANDROID.
Is this safe? Can a malicious Rom writer intercept any attempt to flash a Recovery and keep itself on the phone (sort of like a rootkit)?

I have never heard of malicious roms. Also, for a hacker it would be easier to just write a rootkit for the system. Anyways, just test a rom which has already been tested by a big number of people

No, it can't.
As long as you don't flash any new firmware files (like we have to do with the HTC One M8 to get it on lollipop) you should be fine with a nandroid backup.
Long story short, if you only flash via recovery and not via fastboot etc. you should be fine.

I would add that, even via bootloader (fastboot), you can replace a rom as, before flashing, any tool erases everything in the system partition.

Not if flashing the bootloader via fastboot. Then I assume it could potentially wreck the ability to boot the other nandroid backup?

Wait, one thing is flashing a rom, another is flashing a bootloader

But a firmware could potentially update the bootloader too? Depending on what's bundled in the firmware?

Well, basically yes, but messing up creating a new bootloader is not so easy, and most of the users would never use it as it is a common rule to flash a new rom in recovery, nobody would download it

Nope. But it's necessary on e.g. the HTC One M8, for all the Lollipop roms to run correctly.
But I think we agree :-)

I don't agree with the other posters and would say: "in theory yes!". The eMMC of today's phones is partitioned in a lot of partitions. For instance, the Nexus 4 has around 25 partitions. When you install a ROM, it typically only touches system, recovery, userdata, internal sd (if on separate partition), cache and boot. But since the ROM has full root access, it could write to just any partition and e.g. even manipulate your modem stack.
In practice, I didn't hear about a ROM which attempted that. And I if a ROM contains malicious code, it will only reside in system, boot or recovery.
My advice to be sure: before flashing, dump all partitions and compute their checksums so you can see which were modified by the ROM.

http://www.techrepublic.com/article/edit-your-rooted-android-hosts-file-to-block-ad-servers/
Essentially:

Use a file manager like ES File Explorer
Locate the file /system/etc/hosts
Remove the line that says anything about yahoo
Save the file
Reboot

If it doesn't work make sure that the file has the correct permissions:

Open ES File Manager
Navigate to /system/etc
Locate and long-press the hosts file
Tap the menu button
Select Properties
Tap Change in the Permissions section
Tap the check box for Group under the Write column (Figure B)
Tap OK
Tap Cancel
Reboot device
