Chrome and Chrome Beta suddenly won't fill up the entire screen on launch
So, I'm currently on the N5X rom with a cyanogenmod 4.4.4 base on my Samsung i9300, I restored Chrome Beta from one my backups in titanium Backup, after flashing the latest version of the ROM recently.
But every time I launch Chrome or Chrome Beta from the drawer, it comes up, staying right at the center, here's a screenshot:

Its so strange, it doesn't force close or pop up with any errors, everything works fine except for the part where it just starts fixed to the center of the screen.
What I've tried:

Uninstalling Chrome Beta and Chrome, and then re-installing both
Wiping data and cache of both browsers.
Re-flashing the ROM.

So here's what I've noticed, sometime last month when I flashed a Paranoid Android nightly, both Google Browsers behaved this way, and I thought it had to do with P.A then until this happened. Firefox works fine though, just Chrome and Chrome Beta.

What if you reinstall it through Google Play instead of by restoring from TiBu?

I already did that for both Chrome and Chrome Beta.

In that case my best guess is that it's caused by the theme customizations in this ROM. Likely the Paranoid Android build you tried had the same problem. You might try putting the developers in touch with each other to help them fix it.

This is happening in any custom ROM that supports floating windows. It is there, for example, in SlimKat, Spirit ROM, CM based ROMs etc. In my case I can move and size the window, and there is a maximize button available. It resizes the window with pinch to zoom automatically rendering it almost unusable.
This is an app issue ultimately, but it is specific to custom ROMs with this functionality.
The only thing you can do it, open the Chrome window then bring up the task manager and select Chrome and it will fill the screen as normal. This is obviously an awkward work around.
Alternatively if you have Xposed installed you can try to Blacklist Chrome from xFloatingWindow and see if it will work. Some, but not all have had success with this.

According to AndroidPolice is actually caused by a bug in Chrome Beta that showed up on certain custom ROMS. The recent update (v39.0.2171.90) contains a fix for this issue. It's likely that the next update for non beta Chrome will include a fix for this too.

I've exceeded my unlock attempts (10). Is there any way to unlock my phone?
Due to AT&T being a horrible company, I believe the customer "service" has led me through more than my allotted attempts at unlocking my phone. Because my phone was refurbished, the attempts may have already all have been used. I believe my phone is now "Hard Locked"
Anyhow, my contract is over but I'd love to keep using my galaxy s3 on a different network. Is there any way to reset the unlock counter so I can unlock my phone? I'm willing to pay for an unlock code or go through the process of rooting my phone if necessary.

Have you tried a factory reset?

What exaclty is locked? The SIM card? If this is the case, you should be able to simply remove it. The SIM card itself won't be any good.

If your sim card is locked then you can just remove it and put another one in.
If the phone itself is locked, you can do a factory-reset by using the recovery, hold power, home, volume-up until you get to the recovery screen and choose the factory reset option.

You need to contact AT&T and request your puk1 and puk2 codes (not to be mistaken for a 'pac' code) This will be free to do. Now it depends on what/how you have locked your phone as to which of the puk codes you need to use.

gmail inbox contents disappeared mysteriously
This has happened to my wife twice on her LG Optimus G phone, once about a week ago, and again just today.  She pulls up gmail on her phone, she taps on edit, and begins typing in an email address.  She sees the address she needs in the autocomplete.  Then decides not to finish the email.  So she taps the back key on here phone to get back to the gmail inbox (the page that gmail always wakes up with) and Whoa!  Her inbox is now empty!!  Where did all the emails go.  She then pulls out her laptop and checks her gmail from there.  Inbox still empty.  Can't find the emails under all mail, trash, or spam either.  They are gone.
Has anyone else out there experienced this problem?  Any ideas?  I'm wondering if it's a bug in the new gmail app (that downloaded itself a couple of weeks ago).  Or could it be some kind of a virus?   Anyone have any ideas?  Please help.

Which Gmail app are you talking about? "Gmail", or "Inbox by Gmail"? You've tagged your question with both.

I'm not sure.  I guess regular gmail.
App Info says "Gmail Version 5.0 (1569867)".  Thanks

Unable to add corporate account with same email address as google account on Lollipop
Just upgraded my Nexus 5 to Lollipop and have bumped into a serious issue with account management.
I have my Google account registered to a non-gmail domain, and use Exchange Online to host it. Up to Kit-kat, this presented no particular issue: I would  log in to Google’s services using my Google account and then add a corporate account to handle email.
Lollipop prevents me from doing so however: whenever I try to add the corporate account I get an error message saying the account I’m trying to create is a duplicate (this happens at the very first screen, when the only available field is the account’s email address - which of course is going to be the same).
Has somebody found a way around this? If not, what is the best way to submit a bug report, since the Gmail App is not part of AOSP?

Android Lollipop with Nexus 5 - Proximity & Notification Bar
I've updated my non-rooted, Nexus 5 with an OTA update to Android 5.0 Lollipop and since then I have noticed quite a few things.
I am not sure if those are bugs or not.

The Proximity Sensor does not turn off the screen when I am on the call. Network Calls or Viber or Google Hangouts, all the same.
When any notification arrives, the notification is not clickable. I.E when any hangout call or WhatsApp message arrives, they cannot be clicked until the notification bar is dragged down.

Any guesses?

It's not new that you need to open the notification tray to click on notifications. As for the prox sensor, other Nexus 5 users with problems after updating have found that a (backup followed by a) factory reset can fix the problem. You might try thatl

@DanHulme No but the notification preview is supposed to be clickable (atleast it looks like it) & yes thanks, will try that.

The notifications are clickable. You need to double click the notification to open the app on lock screen.

@VishnuPrasadKallummel Things started working normal after restarting my phone. Its weird though. I have to restart it regularly. Or some features like: Brightness/Proximity stop working.

I would recommend a factory reset. If it is feasible.

Is deleting framaroot app will compromise or delete as well the root permission in my android device?
I'm using security as my antivirus, and whenever it updates, ot always scan framaroot app as a virus/riskware. Can I just delete framaroot app in my device and won't compromise my root?

If a "root access" app is malware, it's beyond hope. It could have written itself into the core of the operating system, in the anti-virus, in anywhere. It's game over.
However, it's likely that the antivirus just sees that the app uses a security exploit (which is how any app gets root) and suspects it of being a virus.

Yes you can safely uninstall Framaroot, without compromising root. Since the file is so small it really isn't necessary.

Your " security " app will always detect a virus on an app that roots. Reasoning is it is using an exploit on a vulnerability in the OS.

system app not working
I have a widget to turn data connection on and off. Since I upgraded my Nexus 4 to Lollipop, I get the message "widgetsoid needs to be installed as a system app"
So I rooted the phone, moved the apk file from /data/app to /system/app. I set the permission to 644. Rebooted the phone.
Still, I get the the same error message. Do I have to uninstall the app, and reinstall it from the apk?
What am I doing wrong? I use a custom launcher, if that matters.

Can you post the complete name of widgetsoid apk folder that you moved?

How to install Widgetsoid in system/app folder?
With ADB connected to the phone:

Mount/system in read-write mode.
Run the command adb push Widgetsoid.apk /system/app/Widgetsoid.apk
Remount /system as read-only.
Reboot your phone.

How to import contacts from a delimited list?
I use an Android phone, and recently I had to delete all my contacts because it was cluttered, and now I have to add all of them again. There are about 200 contacts, and I have them stored in a text file.
My list of contacts are in this format:
Henry Warren  | 9336982147
John  | 9012345678
William Lance Berkman | 9011423655
John Michael Stipe | 9123457819

How can I add these contacts to my phone? I have been trying for the past 2 hours to convert it into CSV format and Import it, but it's a painful job (and messy) because of the several fields. I've also tried various apps from the Play Store to try and import these, but none of them worked either.
There's probably an easier way to do this, so I figured I'd ask here. Any ideas?

If you've spent hours doing it the automated way, you didn't spend it typing in, and ended up with zero records. If you had spent it typing in, even at 30 seconds each, you'd be done by now. Sometimes manual is still better.

@wbogacz: I finally had to do it manually, but still, this is something I could use later. I suppose others may find this useful as well.

Disabling the notification tray in Android L's (5.0) lock screen
I think that this is a rather large security issue that has come with the release of Android L. I've always had a password on my lock screen for as long as I can remember, but in Android L it becomes nearly useless.
After locking my device I noticed that I can still pull down the notification tray from my lock screen with which I could toggle Wi-Fi, bluetooth, and data.
If someone was to steal my phone, they could easily turn off any wireless connection even with the phone locked - preventing me from tracking my phone (I realize that they can just turn off the phone and use fastboot to flash a new ROM onto it, but let's assume they're not that smart).
Am I just missing some magically hidden setting to disable the notification tray in the lock screen?

See if my answer works: Lollipop hide quick settings on Lock screen

No, you're not missing a setting. This particular decision seems very unfortunate, and a ticket opened with google to resolve this has already some support : Google code ticket.
We can only hope that this will be reverted to the previous behaviour (allowed only when the lockscreen had no pin/password/gesture) or made into a setting.

Upgrade from Android L to Android 5
I rooted my nexus 5 and upgrade the developer images of Android L (build number LPV79) back in June or July. Now. I'm waiting for Android 5 OTA. Will I be getting it? How can I check when it will come? All my apps updated to Android 5 so they are not working and crushing because they are not compatible. And I'm not getting any support from Google / Android. Who can help me?

There is no OTA update from the developer preview to the official release. You have to download the release version and flash it using fastboot.

theres the official OTA updates knocking around online, but just 4.4 update to 5.0. you will need the stock "locked" bootloader with kitkat for it go ahead and you need to sideload it via adb. not sure if you can wipe the rom and install it fresh but there is the official full rom from the dev sites anyway. mine took an hour from start to finish from 4.4 offical to 5.0 OTA. all apps updated and works great. I never jumped onto the pre release as i wasn't desperate for it. I have no critical apps and all mine use current APIs anyway.
sorry if you already know this but im sure at some point this will help someone :)

Kindle Fire HD on-screen keyboard on Nexus 5
I have found the keyboard on the Kindle Fire HD to be one of the best mobile device on-screen keyboards I have used and am wondering if it's available on any other devices?
Much like other android alternative keyboards such as SwiftKey, is there a version similar to the Kindle keyboard that I would be able to install on my Nexus 5?
Thanks.
Device: Nexus 5
OS: Android 4.4.4
Rooted: Yes

Maybe you're looking for this?
This is the stock Kindle Fire HD keyboard.And this is the actual link if you're concerned. Don't follow the instructions mentioned on the link.It is only to replace the system keyboard.

It would be better if you also state the name of the app (LatinIME.apk). Also, avoid direct link to file-sharing site and use more credible site such as Google Play Store, XDA Forum, GitHub, etc. We discourage file-sharing site unless it's 100% safe, which we can't ensure.

Andrew, thanks for your suggestion.Had edited the answer earlier through stack exchange android but changes did not reflect.So edited using desktop.

adb unable to recognize Google Glass on Windows 7
On Windows7, I've updated the Google Glass android_usb driver configuration file to reflect the correct VID and PID and it does show up on Device manager as Android ADB interface.

While the device driver version is correct, it is showing up as SAMSUNG Android phone.
More IMPORTANTLY, it still doesn't connect to adb.

I had the same issue. Glass was showing as SAMSUNG Android phone as well. My steps to fix issue:
win7:
https://stackoverflow.com/questions/20435778/google-glass-is-not-listed-as-android-device-by-adb

Click on: Update Driver
Click on: Browse my computer for driver software
Click on: Let me pick from a list of device drivers on my computer
Click on: Have Disk... (that options is in the bottom right corner)
click on: Browse...
navigate to the location of your edited android_winusb.inf driver then click open then click ok then click next
wait a moment then you should see "Windows has successfully updated your driver software". then click close and close again.

!!!(now here is the important part)!!!

Right click on the device and click uninstall.
check the box "Delete the driver software for the device" then click ok
wait about 5 sec then unplug your Google Glass from the computer. wait 5 more sec then plug it in.
Watch the magic happen!!!! its working!!

Moto G (1st Gen) xt1033 lollipop
Recently the 2014 edition of the Moto G got the Lollipop update. I wanted to know the exact date on which the 1st Gen Moto G will be getting the update?
Also, can flashing the update of the 2nd Gen on the 1st gen prove to be dangerous? Can anyone provide me with a link containing android lollipop for moto G to download?

Flashing 2nd gen file into 1st gen phone can completely brick your phone!

Agreed with this; the company's decision to give two different phones the same name doesn't change the fact that they are different.

Phone creates a Wi-Fi network (i.e. WiFi tethering) while being visible on said network. Possible?
I have a vague concept for a piece of software I want to write, but I'm facing a problem in that I'm not sure this is even possible with the way Android handles creating Wi-Fi hotspots in its current iteration.
Basically, the device needs to create a hotspot, while being present on the hotspot's network and visible to the other devices, since it needs to act as a server. Is this something that's currently possible on Android, or would you need two separate devices, one to create the network and another to connect to it and act as the server?

I believe that Android does not support ad-hoc networking out of the box, but there is some software out there to do so (though I haven't tried anything myself).  However, isn't the AP normally accessible in a standard setup?  E.g., a router serving pages on 192.168.0.1.  Have you tried accessing the device from something connected to its hotspot?

Yeah, I've done some testing in the meantime and the phones can ping each other at the very least. I'll have to set up some servers and see how those fare. Thanks for the help!

Do you want to implement an intranet server of some sort through witeless hotspot?

Is there a way to black out screen for a particular app when viewed via task switcher?
I have a Nexus 5 and I recently installed Android 5.0 (Lollipop).
The task switcher in Lollipop makes is much easier to see the screen contents of each background app as you are switching between them.
I notice that my banking app shows the contents of the screen in black when switching to it - an obvious security measure as you don't want people viewing your banking details.
Is there a way to apply this security measure in a more general fashion to any app?  An obvious workaround is to close the app each time you exit, but this is a bit annoying.

Google Now Accent Bug (Lollipop 5.0)
I updated to Android 5.0 yesterday on my Nexus 5.
I am from the UK, hence I have my languages set to "English (UK)" where possible, including the voice of Google Now, which has the accent of an English woman.
After this update Google Now appears to be partially ignoring my language settings in relation to accent. If I ask it something that Google can answer, such as "How far away is the sun", it replies with an English accent, but if I ask it to do something specific to my phone, such as setting an alarm, it replies with the accent of an American woman.
Is this a bug, a weird feature or is there a fix?

Seems to be happening to me too, rather jarring at first.

Used device manager once, now I can't set security to 'none'
Phone is an LG Nexus.
I was messing around with security settings and decided to try using a pattern to unlock my phone. No more than 5 minutes later, I completely forget the pattern I set. Did some googling and used Android Device Manager on my PC to remotely set a password on the phone. Successfully regained access to my phone.
I prefer to have no security on my phone specifically to avoid situations like this. My problem now is when I go to security settings, the "None" option is greyed out and says "Disabled by administrator, encryption policy, or credential storage." So I selected Device Administrators and un-checked "android device manager."
But I still cannot select "None." Encryption is not enabled. I'm tempted to select "clear credentials," but there's a big list of default credentials and I'm afraid removing them might be bad. Is there a specific credential I should disable?
TL;DR: Can't set screen lock to NONE. Android Device Manager is disabled. Not sure if I should clear all credentials.

Ok, just posting an answer in case someone with the same problem finds this.
I took a change and hit "clear credentials." Afterwards I was able to select NONE for screen-lock again. So far haven't noticed and side-effects to clearing credentials.

Open bookmark list in new tab using chrome 38
I usually surf with multiple tabs open.
There is a new fancy version of Chrome-android, (38.0.2125.102 and later), and with it disappeared the possibility of seeing the bookmarks list when opening a new tab. Now it always defaults to a google search box, a google logo, and some icons displaying often-surfed-to web pages. If I wish to view my bookmarks I have to click the tab for bookmarks at the bottom of the screen. How can I make it quicker to open bookmarks again?
Solutions I've discarded

"Ok, so just open the bookmarks list directly then?"

I would, but the bookmarks list opens in the active tab, not in a new one. So that only works if I wish to replace the current page, which is seldom the case.

"It's just one more click, it can't be that bad?"

The number of clicks has increased by a factor of 1.33, that is not insignificant for an action that is taken very often. But worse, it breaks my flow when surfing.

"Switch to Firefox?"

I have. I don't like the font scaling in that browser. Still, it's my fallback for now.

"Undo the chrome upgrade, stay at version 37."

Insecure, and really hard to do after-the-fact. You can uninstall all updates, but then, depending on OS version, you go back all the way to 32. That is not good.
tl;dr:
How can I open one of my bookmarks in a new tab with as few clicks as possible using Android Chrome 38+?
Before 38 it was 3 clicks. Now it is 4. A minor issue one might think, but tell that to my muscle memory.

How to change default homepage
My GSM provider hijacked my default homepage and I want to change it. There is no option in android ( nice open system right ? ). So does anyone know how to change it ? Device is rooted.

Have you tried going to Settings→Apps, scrolling to the Browser, open its entry, and "Delete settings"? Note that this would also clear your "other browser data/settings" you might have changed, and most likely also bookmarks, passwords, etc. Alternatively, there are plenty of Web Browsers available for Android, so you could simply switch to another ;)

I assume you are using the default browser that is provided in the android mobiles.
If so, Open your browser, go to settings by pressing the menu button, now go to General option and then set home page to whatever you like.
settings-->General-->Set Homepage

There is entry "Default page" that can't be changed. That's the entry I want to change/remove.

Your provider may have blocked that setting.

Device is sim-free. Either way, how do I change it. Where is that information stored ?

Determine app that keeps turning on bluetooth
I recently got back from a holiday without internet, when I got back heaps of my apps updated and one of them now continuously turns my Bluetooth on. How can I determine which app it is?
I have a rooted Nexus 4 running 4.4.4

Are you sure an app is turning it on rather than the turning off failing.  I have seen this behaviour from the BT driver stack.  A reboot may help.

@ifor good idea Ill try rebooting now

@ifor unfortunately its not the Bluetooth failing to turn off http://youtu.be/usAAU0kEhtg

Check in Android settings. Security and privacy --> permission--> Turn Bluetooth on. Check which apps you want to keep enabled.

For me it was FireChat.
With aSpotCat you can check which apps have the permission to turn bluetooth on/off.

Where is bluetooth permission in this app?

I have to first swipe it right or left then go to the call or sms to continue.
Any idea ?

Having the same issue around here. I found that waiting for the notification to go by itself is better than Swiping right since you can still access the notification on the drawer and go directly where you need to.

Is Asus Memo Pad 8 limited to 2 users?
Asus Memo Pad 8 tablet, running KitKat 4.4.2, doesn't allow me to create a third user.
Is this an undocumented 2 user limit or is there a bug in the Settings app? Is there any workaround?

"doesn't allow" What actually happens?

Nothing happens, the "Add user" option is not responding when there's a second user defined. It works normally again when the second user is deleted.

I used to have that tablet and the maximum number of profiles were two. So if you want to have more than two accounts I would suggest you to root your devices.

How do I send articles viewed in my web browser to my Kindle from android
In my desktop web browser I have the Amazon "Send to Kindle" add-in which produces a readable version of a web page and sends the article to my Kindle for reading later.
I use this primarily for newspaper articles to read them later on a larger more readable screen and I don't usually have an internet connection when reading articles on my Kindle.
What I'm looking for is a product or solution which achieves the same on my Android device.
What I've tried already:

I can print web pages to PDF from my Android device and send these PDFs to my Kindle, this is not ideal as I just want the text content to read.
The Instapaper Android app lets me send a link to an article to my Kindle, but it doesn't send the readable version of articles it has created. I can push articles to my Kindle from the Instapaper website, but then I might as well use the Send to Kindle add in.
I tried to install the Readability Android app, but this refused to let me create a new account from the app.

I've been looking for something similar too - there doesn't seem to be an official Amazon option.
The closest thing I can find is 'Push to Kindle' by FiveFilters: https://play.google.com/store/apps/details?id=org.fivefilters.kindleit

Google photo backup
I just got a new phone that doesn't have a slot for my old memory card (it has 32gb hd) I backed up the photos on the old phone to google. Now, how can I get them or some of them to my new phone?

What exactly did you do to back them up?

If you uploaded them to Google Photos, you should be able to log into your Gmail account and simply open up the Photos app.

I actually had to delete them all from the Google + site and then upload them all over to get them to the new phone. Thanks for the suggestions.

The Google+ app provides access to all the photos and albums in your Google+ account.
It also offers you to upload automatically from any photo directory it detects on the device:

Google+ Photos is a great way to save all your photos, bring the best moments to life, and share with the people that matter. Your photos and videos are stored privately and accessible from anywhere, plus when you turn on Auto Backup they’ll be automatically saved. Relive the moment with photos presented as rich stories, movies, animations, collages, and more. You can find the right photos fast by searching for what’s in the image, even if it’s not in the photo description. And easily add a personal touch with filters and built-in editing tools.

I am locked out of my galaxy centura how do I reset
How do I unlock my galaxy centura I forgot my lock screen passwords
I have tried pressing power and volume down and still nothing

When power is off, press screen off, volume_down, home for about 1-2 seconds, then keep pressing vol down and screen off but release home key.
It should take you to screen with few options, vol down to go down, and vol up to go up, home to apply option.
Then the rest is easy, use atleast these options, factory reset, wipe user data, wipe user cache, and format system if it has option like that.
NOTE: I tested this on my Galaxy Tab 2 and it worked, you need to google if it's safe to format system with your phone, it's no sin to feel safe.

FBTrueType-android
I have written a native android program FBTrueType-android to print TrueType font text directly to the display on the device using ADB.
It has many features including clearing the framebuffer (display) and changing the *.ttf font used, font color, font size, x and y positions.
It also can run with Zygote (android interface) running and it can capture the framebuffer from Zygote in fullscreen.
I setup a github repository for it which you can access here, alternatively you can clone the repository like this:
$ git clone https://github.com/mikelinux/fbtruetype-android.git

You will need to be setup to cross compile for ARM, the README file has full instructions on doing this.
Enjoy, and please post your feedback.

Hacky workaround: DirectFB
With DirectFB and root access, you can display the text on screen directly, without Android at all.
I've implemented a program for this: directfbtext.
( echo "Hello, world"; echo "FLIP"; sleep 2; echo "QUIT" ) |  /h/bin/directfbtext --dfb:fbdev=/dev/graphics/fb0  --dfb:no-vt  /system/fonts/DroidSans-Bold.ttf 30 120 200 255

Note that it is probably not that easy to get DirectFB working on Android, but I happen to have it already configured.

Update Per user request, I've created and tested a "portable" pre-built version of directfbtext. Setting up and running:

Unpack directfbtext_deps.tar.gz into /data/local/tmp/;
Start adb shell, go root (su);
cd /data/local/tmp/directfbtext;
Create symlink from /usr/lib/arm-linux-gnueabi/ to /data/local/tmp/directfbtext:
# mount -o remount,rw / /
# mkdir /usr
# mkdir /usr/lib
# ln -s /data/local/tmp/directfbtext /usr/lib/arm-linux-gnueabi

Ensure display is on
LD_LIBRARY_PATH=. ./ld-linux.so.3 ./directfbtext --dfb:fbdev=/dev/graphics/fb0 --dfb:no-vt /system/fonts/DroidSans-Bold.ttf --dfb:system=fbdev 30 120 200 255
Type some text, followed by a line that reads "FLIP";
Observe the text visible on the display;
Type "QUIT" to exit directfbtext;
Interact with the device, so it updates display and clears remaining glitches caused by DirectFB.

Maybe you can tell what need to be configured?

The main thing is probably a Debian in chroot.

Could you provide a binary? (Or instructions how to compile with NDK?)

Unfortunately static binaries are tricky to get with DirectDB. The program was build not using Android NDK and depends on Debian libraries. I'll try to hack up "semi-portable" version of it now.

@user1147688, Done. You can try testing it.

How to stop beeping noise from the unencrypt device screen
I have encrypted my phone, and set it so that it reboots each night - this works fine, however after it reboots, it asks for my password to unencrypted the device - still fine, however after a bit, it starts to beep - is there any way I can set it such that it does NOT beep at me? (some morning I like to sleep in, and scheduling those is too much of a pain).
alternatively, is there an easy way to have titanium backup just shutdown the phone instead of rebooting?
or perhaps instead of beeping, just shutting itself back down if the correct password isn't entered in X amount of time?

How did you get it to beep?  Mine doesn't beep and this is bad because if I'm GPS logging I lose data because I don't realize the device has restarted.

@Michael it started as soon as I encrypted my phone (note 2, n7100), but it takes a few minutes to start beeping after a reboot

Ah ok...after a bit more experimentation I found that it does beep on mine too, but it's so soft (more like a quiet chirp) that unless I am in a quiet room (e.g. sleeping without a fan noise at night) it doesn't really get my attention.

'Could not validate certificate signature' error (Antennapod, Gingerbread)
I am using Android 2.3.6 (Gingerbread) and AntennaPod Version 0.9.9.5.
When I am trying to access gpodder.net, either to login or search podcasts, I get the following
error message:
An error occured:javax.net.ssl.SSLHandshakeException: org.bouncycastle.jce.exception.ExtCertPathValidatorException: Could not validate certificate signature.

I tried to clear the cache, the data, and ultimately uninstall and reinstall the app from the Play Store, but the problem persists.
Any hints about what I can do here?

Your best bet is probably to contact the developer. It looks like a bug in the app, perhaps because you're using an old version of Android (but perhaps not). It's unlikely that there is anything we can do to help you.

There is nothing you can do, except making your device not use ssl. Either there's a problem with the website, or a hacker is modifying your connection to the website on-the-fly but has problems.

Thanks. I guess it's a problem with the website, another podcast application trying to connect to the same server gives the same mistake.

hangouts not syncing from PC to Nexus 6
I have the hangouts extension installed in chrome on windows 7 and windows 8 PCs and a stock Nexus 6 which has hangouts installed as a system app. When I send and receive messages on my PCs my phone doesn't update with those messages sent on the PC. I also have a Nexus 7 on lollipop and it syncs messages just fine. My LG G3 also syncs messages. I have tried wiping cache/data in the app, signing in and out of chrome and the google account on my phone, factory resetting the phone, etc.
Anyone have any ideas? I tend to switch between my phone and PC all the time and would live to be able to have synced conversations.

It looks like GCM Push Notifications don't work with IPv6. I disabled IPv6 entirely in my router and now everything is fine. Though IPv6 was enabled for the past two years and I didn't have any kind of issue. Let's hope a Play Services update fixes it.
Here is where I got the answer. On rooted devices, you can install [ROOT] Disable IPv6 to fix the problem.

Unlock 2013 Moto X
I currently have a 2013 Moto X that I purchased from republic wireless which uses Sprint's network (USA).  I would like to leave this prepaid service to join Verizon.  I took my phone to Verizon today and they said that they couldn't add the phone to their network.  Does anyone know how to unlock my phone for use on Verizon's network.
I was about to use this unlocking program on Motorola's website, but I'm not sure if this will be useful for what I am trying to do.

I would doubt the radio hardware is compatible, but even if it was, Verizon generally doesn't allow you to bring your own device. Did they say they couldn't activate it because it was locked to Republic, or did they simply say they can't activate it? And no: the link is not relevant here. Unlocking your bootloader is not the same as carrier unlocking.

they allow bring my own device.  i just need a verizon compatible phone

Right, and generally that means "Verizon branded". I think the iPhone 6 is an exception, but phones from other networks typically cannot be moved to Verizon like that. So again, did they actually tell you that the phone couldn't be activated because of a network lock? Did they tell you it was a "Verizon compatible" phone? If it's not even compatible then the state of the network lock won't matter.

to be honest I'm not 100% sure. I guess I'm looking to see if anyone has brought a non-verizon moto x to verizon by unlocking it

Root GT-I9305 running Android 4.4.4 Build Version KTU84P.I9305XXUFNI3
I want to root Samsung Galaxy S3 LTE GT-I9305 running Android 4.4.4 Build Version KTU84P.I9305XXUFNI3.Can you please help

Many ways to root the i9305. 2 ways i recommend are to use chainfire's method (bit complex) or framaroot (easiest) To do all this,first have the USB debugging enabled. To do so,go to settings and navigate to "About Device". Keep pressing the build number 6 or 7 times til its says developer settings have been enabled. Go back and you will see "Developer Options" Open the developer options and check the USB debugging option.
Framaroot

download framaroot
Allow the framaroot downloaded app to be installed when there is a prompt to whether or not to install apps from unknown sources.
Open the app and select Aragorn
Reboot and you shall have the device rooted.
Update the supersus from the google play store, then open the Supersu app and update the binary. It will ask if you want to disable knox,select yes.

Chainfire's CF-Auto-Root

download CF-Auto-Root and extract to a folder.
Turn phone off.
Press the volume down,home screen button together. Then while pressing those 2, press the lock key and it will ask to whether reboot or go into download mode.
Take note rooting voids warranty. Press volume down to continue to download mode.
Now open the extracted folder and open odin. Select PDA and select the CF AutoRoot MD5 file. Connect phone via usb and lick start. It will do everything and reboot.
Update the supersu from the google play store, then open the Supersu app and update the binary. It will ask if you want to disable knox,select yes.
Then reboot and its fully rooted.

Always consider donating to the developer of framaroot and supersu (chainfire).

Framaroot does not work with Android 4.4.4 on S3 GT-I9305. Note that this device is more likely to have Android 4.3, so most root methods would focus on exploits available in that. The asker asked for a root method that uses exploits available in 4.4.4. (My build number is KTU84P.I9305XXUFOE1)

The correct version of CF-Auto-Root for Android 4.4.4 on m3xx device is here. The link in the answer points to the version for Android 4.1.1 on m3zh device. Don't use that. The rest of the instructions are fine, although I didn't get any prompt to update the binary when I opened SuperSU app. I have successfully rooted my I9305 running 4.4.4.

Can't open specified file error on Odin :-(

Can't open specified file error on Odin, solved on removing the "re-partition" flag and it worked

stuck on establishing connection solved by removing battery and reboot on download mode

OnePlus one is charging but is recognized in device manager only when in debug mode
my oneplus one device (version 4.4.2) is not recognized anymore by the computer (OS WIN8) in the device manager, only when in developer mode - in usb-debug, does it show on the device manager (and even then it is not recognized as a storage device), I have installed the drivers successfully, but the moment the developer mode is turned off it was not recognized again.
Now, I haven't dropped the device and it is protected with a cover, what leads me to believe it may be a software issue.
I have tried already to format the cache partition, and it did not help.
Please help...

You say 4.4.2... Please update it to te latest  firmware.

You say it's not recognised any more: has it previously worked? What has changed since it worked?

Are you using the red/white cable that came with the device? Most standard USB cables are not capable of file transfer, and so will not be recognized with Windows.

This doesn't make any sense.  There are not special data USB cakes.

Nexus 7 does not have Google Play app installed
A Nexus 7 tablet having android 4.4.2, does not have the default Google Play(neither older Android market) app installed.How is that possible?
I tried downloading *.apk file from here and even here
But did not work. When I tried executing the apk file, they hang and I get "ANR - application not responding" dialog.
For other *.apk files for Google store app that i downloaded, it gave errors saying Error saying  - "There was a problem parsing the package".  It just did not work for many Google store apk's different versions i tried downloading and installing/running?
How can one install Google play store on this Nexus 7?
Would there be any correct/compatible *.apk for Google play store available which would work?
Edit Note: I tried checking in settings and elsewhere to see if any default apps disabled setting is checked but could not find any such thing?

You need to see if there are any of the other Google apps (GApps) installed. Most likely if the Play Store isn't installed then the rest of the GApps package is either. The Nexus 7 happens to be very easy to work with, so don't worry.
GApps Manager will be the tool that will be used. The link will describe the toolkit in detail as well as any fixes that have been made.
The Play Store - GApps Manager download.
The tool will be able to show android version, so you won't have to search. This will show all the packages available. The directions are easy to follow. Once complete you'll have the Play Store installed.
The only thing that might cause any hiccups is if you are on a custom ROM, which usually don't have GApps included because of legalities. Then you would find out what ROM and version, then go to the developers website and download the correct GApps from there. The custom ROMs will conflict with stock GApps.

Sure, just repartition the card. Not that you'll lose any data on it, so take backups. Alternatively, if you don't need another kind of partition, you can just change the partition size IIRC. I recommend gparted for editing partitions.

Making the phone LG G2 4G LTE (D802T) use LTE permanently
I have recently purchased LG G2 D802T. In my country 4G is recently launched (Pakistan) but in my mobile while trying to search for networks it has only GSM or WCDMA (No LTE). My question is that how I can get LTE, permanently.
I have already tried several codes, they do search for LTE. But when I open the settings again then it comes back to original I.E. No LTE.
So please help me and also tell that if I need a new SIM for 4G. Also is I need then at least my device should show LTE option because it is written on its box 100% LTE.

Go to phone, and dial: *#*#4636#*#*
Then scroll about half-way down and click on the setting that says: LTE/GSM auto (PRL) to change it to whatever you need.

Why can't I take pictures?
Every time I go into my camera it says "your storage is full" I've deleted apps I've deleted pictures and I've cleared data and cleared cache and everything so why can't I take pictures it and it still says storage full?

Is this a camera on a phone?

Have you set your camera location to a sd card?

What type of device are you using? How much storage do you think you have? Do you have an external memory card in the device?

PIN on lock screen
I have managed to install a wifi certificate, and it forced me to set up a PIN for the lock screen. I absoluterly DON'T want that, because it is very annoying to have to type it every time I unlock the device, which I do quite often. Only all other options save for Password are not selectable. Why is that and how do I solve this?

EDIT:
Looks like it may be the wifi certificate, it's forcing a higher level of security (pin or password). There's a highly technical discussion about that at this older question: Certificate Install without mandatory PIN lockscreen
So you 'll probably either have to deal with the pin or get rid of the wifi certificate.
...
...
...
Go to Settings >> Security >> Device Administrators. See if anything other than Android Device Manager is checked. Uncheck it if there is, and check the screen lock options again.
Also, when posting questions like this, it's always best to also mention what Android Firmware you're running (KitKat, Lollipop...) and your device. Somethings settings option can differ between firware versions and/or devices.
...
...

Nope, nothing else checked.

How do I find out what firmware I have?

Settings >> About Phone (look at Android Version)

Settings>General>About Device says "Android version 4.4.2, Kernel version 3.4.0-2688263 dpi@SWDD6216 #1 Wed Sep 3 13:38:08 KST 2014" and more stuff.

@MickG: have you had a look at my updated answer yet?

I suggest you always notify people of edits as they may not notice them otherwise :). I saw the edit just after seeing your comment today, but being short of time I haven't yet read anything but the question from it. I certainly will read it sooner or later. Thx.

@MickG my previous comment was my notification to you. I made that comment directly after I made the edit.

You probably cannot avoid that on a not-rooted device, as user-certificates enforce this. On a rooted device, you could make it a "trusted system certificate", and thus not trigger the described behavior – assuming you're talking about a certificate as shown in Settings › Security › Certificates in the "user" tab. The corresponding system certificates are stored in /system/etc/security/cacerts/.

Nexus 5 stuck on Google logo at boot
I recently unpacked, modified, and repacked the boot.img file and flashed it onto my Google Nexus 5.  When I rebooted the device, I was stuck at the Google logo screen.  I can access the recovery mode, but "wipe data/factory reset" did not fix the issue (still stuck on the Google logo screen).
I also attempted to sideload the stock image found here:
https://developers.google.com/android/nexus/images#hammerhead
Still no luck, as I was receiving "signature verification failure."  The device's bootloader is not unlocked. Anyone have ideas?  I am not concerned with losing personal data, I would be satisfied with just getting it back up and running.

How did you flash the modified boot image? Just repeat that process with the original one. I would think that should be sufficient.

Thanks for responding.  I basically did an adb pull on the boot.img, unpacked it, modified it, repacked, it and then pushed it back to the device and overwrote the old one.  I don't have adb access anymore since I can't boot all the way, or else I'd just restore a working boot.img.  I used this guide: http://droidcore.blogspot.com/2012/12/how-to-edit-initrc-in-android.html

Well, I suppose the fallback option would be to unlock the bootloader so you can try to use the factory images. You'll lose your data in the process, but as long as you can get into the bootloader you should be able to do it.

Thanks I was able to use fastboot once I installed the proper drivers.  I am back up and running!

There is nothing to worry. You just have to flash the images properly. Please follow the steps mentioned in this Android Enthusiasts answer. The initial bootup usually takes time around 10 to 15 minutes. I'm up and running 5.0.1 without any problems.

How to recalibrate the OS for an external battery?
I recently bought an external non-standard 7000 mAh battery for my Samsung Galaxy S3 but the phone doesn't seem to recognize it.
Is it possible that the phone needs to be reconfigured or recalibrated so as to recognize the difference in the battery capacity?

How exactly does it behave? Generally, external batteries simply act as portable chargers, and are recognized as chargers - not as batteries that can be "used" directly in the manner that your phone's battery is.

Did you check on the manufacturers website or forum?

External batteries are usually plug&go, since they function as chargers. This may seem like a silly question but is the external battery charged? A dead batter won't be recognized by anything. Also,have you tested any other devices with it? Is  your phone the only one that won't respond to it?

I'm sorry if it is not clear, but by external battery I mean this battery pack not a portable charger.

The link in the comment above seems broken: it goes to the product page of a "Waterproof & Shockproof Portable Wireless Bluetooth 4.1 Speaker", not a battery of any kind. :/

@IlmariKaronen I see the link is broken and it was too long ago to remember what exactly it was. Please look at this product which seems similar - https://www.amazon.com/warranty-ZeroLemon-Extended-Protection-Included/dp/B00BXO7YOW

Also, I am not actively seeking an answer to this anymore.

That is most definitely an INTERNAL batery, and I am also curious as to what you mean by "doesn't seem to recognize it". I'm not sure how you could install that externally as you imply. Did you follow the manufacturer directions EXACTLY? Did you charge it completely before powering yor device on? I am most curious becouse I plan to purchase the s5 version of the same battery. I'll try to keep you posted as to my results.
This is the most complete calibration method that I could find. I hope this helps.
How to format a new Li-Ion battery.

Plug in the charger but leave the phone off. charge your phone until the the charge is 'full' not just 100%. Then at least on the first charge leave it another 30 minutes to an hour to make sure it is full/full.
Unplug, and pull out the battery. You need to press and hold the power button for 1 minute to discharge any current left in your phone. This current is needed to store data in your phone’s RAM. If there is any corrupt data in the RAM it will stay there even if the phone is off as long as current is still available. In reality, even if you press and hold the power button for a mere 30 seconds the current will be discharged. It is however best to do it for a longer period of time just to make sure.
Put the battery back in and boot in recovery mode using the following method.
While phone is off Hold down the Home and Volume Up keys.
Press and hold the Power button while still holding the other keys.
As soon as you see the Samsung logo, release all keys/buttons (May need to continue holding volume up and home).
When blue screen appears use the Volume Down key to scroll down to Wipe Cache Partition. (Wipe dalvik as well if possible)
Press the Power button to select it.
Press the Volume down button to highlight "Yes" and press the Power Button to select it.
Wait for a few minutes for the phone to clear the data.
Then press the Power button to select reboot system now.
Wait for your phone to reboot.
Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows "full".
Disconnect the phone from the charger, and power it off.
Pull out the battery. You need to press and hold the power button for 1 minute to discharge any current left in your phone. This current is needed to store data in your phone’s RAM. If there is any corrupt data in the RAM it will stay there even if the phone is off as long as current is still available. In reality, even if you press and hold the power button for a mere 30 seconds the current will be discharged. It is however best to do it for a longer period of time just to make sure.
Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows "full".
Disconnect the phone, power it on, and use it.
Use the phone till it shuts off by itself due to exhausted battery.
(1st time ONLY, turn on and drain battery until phone shuts down [repeat until you are unable to turn the phone on- this step is very important because we need to drain the battery completely])
-Charge till "full" before turning back on.
Repeat step 17 - 6× for ZeroLemon, or high capacity battery (3× for standard battery). (This step takes DAYS.)

You should only use this sequence one time.

Note: The easiest way to calibrate your battery is to allow it to fully discharged (until it turns itself off), then plug in the charger but leave the phone off. Charge it until "full" while the phone is off. When it hits "battery full", unplug it and turn it on.

Recommend is do not continually drain battery below 10%, battery calibrates itself via onchip. Generally, using the phone for a week will recalibrate it. Previous steps are only recommended for a new battery.
Personal suggestion is do NOT repeat step 17 any more than the manufacturer recomends. Completely discharging,  or keeping a Li-Ion battery at "full" charge WILL place undo stress on the "chemical" battery and reduce longevity.
Also it does seem to make sense to get the most accurate possible reads for 100% AND 0%, especially with a new high capacity battery.

Do you have any evidence to support that this method works? I'm not sure if dalvik cache has much to do with the battery calibration.

Honestly, I have checked to see that the described method (steps 4 through 7) do boot to recovery mode. Also ZeroLemon website does make passing reference to the need to fully charge and discharge their batteries 6×, as well as full instructions in the package. Aside from that, no I haven't verified anything else. In fact when I booted to recovery I only chose to reboot as it was just for verification purposes. Also my menu made no reference to delvik, so.... Performed on Galaxy s5, will update when I get my high capacity battery.

Not all rechargeable batteries deliver the fully rated capacity when new and require formatting. Formatting completes the manufacturing process and occurs during early usage when the battery is being cycled. Lithium-ion is a very clean system. Additional formatting makes little difference because the maximum capacity is available right from the beginning, (the exception may be a small capacity gain after a long storage [such as a newly purchased battery]). Nor does a full discharge improve the capacity once the battery has faded. A low capacity signals the end of life.

A discharge/charge may only be beneficial to calibrate a “digital” battery; it does nothing to improve the “chemical battery.” The on board overcharge protection chip stores [at least] the battery code and tracks battery readings that typically include voltage, current, temperature and state-of-charge information. A SMBus battery contains permanent and temporary data. The battery manufacturer programs the permanent data into the battery, which includes battery ID, battery type, manufacturer’s name, serial number and date of manufacture.

The temporary data is added during use and consists of cycle count, user pattern and maintenance requirements. What most “smart” systems ignore is the condition of the battery. They assume that [all] packs are running close to the original capacity and that all cells are well balanced. Such a condition only exists when the battery is newly [manufactured].
It should be noted that although battery life is determined by construction li-Ion batteries typically have two additional controls.

In cellular phones for example there is the on board chip noted above, but there is also a software controller [in the using device] as well which will also stop the charging process when it estimates a full charge (a typical redundancy). This would be the reason that while the battery itself should not need recalibration it will suffer reduced usability without calibration.
Information compiled from batteryuniversity.com
I used cut and paste method and placed all additions and corrections in [brackets].

Also, several places batteryuniversity.com strongly recommend against either keeping Li-Ion batteries at full charge or completely discharging them as this places undo stress on the chemical battery and reduces longevity. To that end the only logical conclusion that I could reach is that the fault actually lies in the phones power management software which when uncalibrated can cause symptoms observably similar to a dieing chemical battery.  It would only be the software that requires calabration, which is bad for the chemical battery.

@1990clb ok, I said that I'd update when my battery arrived so... my ZeroLemon 8000mAh tri-core arrived yesterday,  and the first thing I noticed was that it covered the speaker.  Neadless to say, I immediately sent it back as not conforming to the description as eleminating the speaker function (in my opinion) makes it non-compatible with the Samsung Galaxy S5. I didn't charge it or check the instructions above. The replacement I have now settled on is a double core that does support full functionality of the phone. The manufacturer recommends against recalibration.

If something doesn't work, or in any way is not compatible with your device then immediately send it back.

How to 'force' update apps?
I am currently using Huawei's smart phone. The has KitKat installed and it is rooted.
Huawei's app center shows that updates are available for a number of apps (not system) but the same apps updates are not available via Google Play Store.
I don't want to update my apps via App Center of Huawei.
Is it possible to force Google Play to check for update and then update the apps? Any app available for that?

Some apps use the "staged rollout" feature of Google Play, which means that not all users get the update at the same time (I'm not entirely sure on exactly how it distributes the updates, but it does). So no, if the update is not shown in Google Play, the only way to get it is to wait.
However, APKMirror provides (some) APKs which you can manually install by downloading them onto your device and installing them
Note that "Unknown sources" should not need to be enabled, as the majority of these APKs seem to be the original, signed APKs - that is, the APK's cryptographic signature guarantees that it is unmodified from the company.
How does this work? I'm going to skim over the details, but essentially, the company that produces the app (for example, Google) has a secret "key" which they use to cryptographically sign the APK. Android checks that the new version of the APK is signed using the same key as the one that's installed (and that all the files within it match checksums provided by the APK), and if it doesn't (meaning that the APK has potentially been modified by some third party), it will refuse to install it.

Interesting, I just knew about "Unknown sources" is not needed for original, signed APK. I though it's needed for all APKs downloaded manually. Haven't experimented about this though, so I don't know.

Android 5.0.0 on Nexus 5 stuck on boot logo
I just recently received the 5.0 update for my Nexus 5 and now my device fails to boot. All that happens is the Google logo gets displayed on the screen and then the device does nothing else. I am able to get into both the bootloader and recovery.
First I tried wiping the cache with no results. Next I did a full factory reset with no results. After that I decided to just flash the factory images directly. Unfortunately this didn't work either. I went back into recovery and discovered that there were a series of error messages displayed in the recovery menu...
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
E:Can't open /dev/block/platform/msm_sdcc.1/by-name/misc
E:failed to mount /cache (No such file or directory)

Also after these messages were displayed I could not wipe the cache or do another factory reset.
Luckily I am able to flash the 4.4.4 factory images and boot the device successfully so my guess is that something might be going wrong with the installation.
Has anyone else encountered similar errors when updating to 5.0?
Thank you in advance for any and all help!

Hi, I'm having a similar issue. Did you manage to fix this?

I haven't found any solution yet that has worked for me, besides reverting to KitKat. This issue also happens for me when I try to do the 5.0.1 update as well. I haven't tried the 5.0.2 update yet but I probably will soon.

OK thanks. I gave up messing around and bought a new Nexus 5! Kind of wasteful, but nothing worked and I really needed to fix a bug asap.

By the way, when reverting to Android 4.x, do you find the camera and other apps crash instantly on boot and become unusable?

I have been considering just buying a new one too but I've just been making due with KitKat for now. When I revert to 4.4.4 my device is stable and I do not have any app crashes. My only issue it my bootloader no longer wants to relock itself. Every time I reboot it unlocks.

I have a new Nexus 6 which immediately updated to Lollipop. When in standby mode the screen turns on randomly and displays the clock. This has been going on since I got it 24 hours ago.
Any thoughts or tips to fix this issue?

It might be daydreaming. Did the screen turn on when you charge or dock the phone?

Sorry for the delayed response. No, it is just sitting still. No charging.

I turned off daydreaming. Still happenjng. Very strange.

After having switched off the Ambient display the problem has stopped for me. Hope this helps.
Settings > Display > Ambient display (Wake screen when you pick up device or receive notifications)

You can try by going to Developer options and then disable the Stay awakecheck-box. ("Screen will never sleep while charging")

App to OCR pre-existing PDFs?
I am in grad school and have a samsung galaxy tablet that I primarily use for reading and annotating PDFs. Many of these docs are scanned book chapters and have not been run through OCR before I download them to my tablet. I'd like to be able to run them through an OCR app so I can search the text. On my PC I use Acrobat Pro, which has this feature built in, but there doesn't seem to be anything comparable available for Android. I use EasyPDF Reader Pro to read and annotate PDFs on my tablet, and really like it, but it does not have an OCR feature. All of the OCR apps I've found on Google Play and by searching online seem to be geared toward recognizing text in photos and some will output a PDF, but none seem to take an existing PDF as an input. I suppose I could just convert the docs on my PC and reload them from there to the tablet, but this is a hassle and seems to defeat the purpose of having a tablet. Any suggestions on an app I've missed, or any OCR developers out there who want to cook something up that would be really helpful to all of us grad students?

Is it possible to disable the access in the lock screen to the dialer and the camera?
I've updated my rooted, Nexus 5 with an OTA update to Android 5.0 Lollipop and since then I have noticed something that quite bugs me.
After the update has been added to the phone lock screen access to the camera if I slide to the right, and the dialer if I slide to the left.
I liked the old method (without any additional apps in the lock screen)
How can I disable/remove them from there?

One way is to use a custom lock screen.

Google Voice Search no longer automatically takes action
I was recently using my phone and noticed something odd. Previously, when I used Google Voice Search, and I said something like "Set a timer for 10 minutes", my phone would recognize that I wanted to set a timer, and if I took no action, would automatically start the timer after a short duration. Now, when I take this action, the phone recognizes the voice command, but only has a button labelled "Start Timer".
I'm not sure what in particular has changed, but I haven't found any similar problems via Googling. The only thing I can think of is that I recently upgraded to Cyanogenmod M11.
How can I regain the previous behaviour of Google Voice Search?

Same here on Xperia Z2..
If you uninstall updates to the Google search app functionality is restored so it is definitely a Google update

Battery charging however phone not turning on, after being in a puddle
A while ago I dropped my Samsung Galaxy S in a puddle, the phone came apart (the battery & back cover came off). I quickly wiped the parts and put them in my pocket (without turning it on), when I got home I opened it up, wiped the parts and left it in the window sill for it to dry.
About 3 days later I checked to see if everything was working but only the Samsung logo came up at the start, then it just froze. The next morning I tried turning it on to see if it worked and it wouldn't start, completely. When I try to charge it, it doesn't show a battery sign and it won't load up into recovery or download mode.
Since I had downloaded a custom ROM I'd hoped plugging a USB jig in would get it in download mode so I could redownload the original ROM – however it didn't do anything.
I know the battery is charging as I checked to see if the battery was working by connecting it to a led, it didn't start so I knew the battery was dead; I left the phone plugged in and after about 10 mins I checked to see if it would work so I connected an LED light and it worked.
The battery is definitely charging so the problem isn't the battery, could it be the screen? Or something wrong with the circuit? Whenever I touch my phone screen, it does seem to be moist and wet.
Any help appreciated, I'd like not to get a new phone so if there is any chance of recovering it please let me know.

Most likely it is a hardware problem. Take it to a local mobile service center for confirmation.

would it be possible to fix it?
Also is there a way to check for short circuiting?

If the screen is still moist, then there's probably moisture trapped in the phone despite sitting on a window sill for three days. Try placing your phone in a small airtight container full of rice for a couple of days, with the back cover off and the battery removed.

will do :), il let you know how it goes

cell phone make screechy noises while on call
I'm using Sony Xperia J , Why does my cell phone make screechy noises while on call? sounds like a dial up modem
also , my cellphone is not rooted

There are three reasonable possibilities:

Your phone has a problem, most likely hardware.
Your service provider is having problems.
Your phone is not fully compatible with your service provider.

Possibility #1 is the most likely.
To check for #2, call your service provider and see if they are having issues.  To check for #3, ask your provider if your phone is compatible with their network.

Cannot open Android 4.1 on PC as in mass storage mode
I cannot open my phone in Mass Storage Mode.
I've tried using the MTP and PTP which were on the list on USB settings and I've tried using Eclipse in ADB (which only copies one file at the time).
With MTP, the file transfer stops when it gets on a big file.
With PTP, I can only see photos.
There's another phone which is older and has this ability to be displayed as a drive, but why doesn't this newer one have it?
Is there an app where I can transfer files over Wi-Fi maybe? Don't tell me Dropbox because NSA spies on it and it takes a lot of time to upload it there. Is there an app that bypasses settings and makes my NONROOTED phone capable of initiating Mass Storage Mode?

The above covers the first part of your question; the second part is answered at http://android.stackexchange.com/q/20670/12442 (summary: there are many such apps).

apps download error
Whenever I try to download apps I receive error "error while Dowunloading-application name" there is insufficient space on the device.
Please help me to overcome this and I have sufficient space on device and SD Card. Sony Xperia C2305. Android 4.2.2

It's happening because application download from the store first heads over to the internal storage of the device which I guess isn't enough, what you can do is try moving some of the application installed/music/pictures over to the SD card in order to free up the internal storage. You can also try clearing the Dumpstate/logcat to try freeing up some space you can do that by pressing *#9900# and select the second option "Delete DumpState/logcat" and see if this helps you in freeing up some space.

What's the difference between a factory image and a ROM?
Why are ROMs flashable through recovery while factory images require fastboot?

The factory image is just the ROM that's on the phone when it leaves the factory. It sounds like you might be thinking about different kinds of ROMs.
When you download a stock ROM from the phone's manufacturer (or elsewhere), it usually includes the image for the system partition and one for the stock recovery. In contrast, when you download a custom ROM, it usually just includes the image for the system partition, and it's expected that you already have CWM, TWRP, or some other third-party recovery installed.
Obviously you need fastboot to flash the recovery - you can't overwrite the recovery when it's running - so you need fastboot to flash a factory image (when it includes the recovery and the system image), but not necessarily if you're just flashing the system image (from a custom ROM).
A ROM can be a custom ROM or a stock ROM (aka factory image). The difference only comes because of the different ways that first- and third-party ROMs are distributed.

So then is it possible to flash these using CWM? What file in there would be the equivalent of what you would flash as a custom ROM? When I extract, I do see files like boot.img, system.img, recovery.img, etc.

Each .img file gets flashed to the partition with that name, so the system.img is the image for the system partition. As I said, most custom ROMs only include a system partition, because they assume you already have a custom recovery, and there's no reason for every custom ROM to include a recovery.

So I could theoretically just flash system.img through CWM and expect a fully functioning Android OS? Doesn't it require a zip file though?

This article made me understand the difference http://www.howtogeek.com/193055/what-is-a-custom-recovery-on-android-and-why-would-i-want-one/
They are the same concept except that that custom recovery allows certain things like introducing custom ROM. Flashboot is the built-in recovery environment of Android which is limited and definitely does not allow you to introduce custom ROM.

Fastboot is not the built-in recovery environment for Android. It is a special boot mode for flashing partitions and a few other developer tasks. Android has a real recovery environment, which is typically used for flashing OTA updates. If you have a custom recovery, it replaces the built-in one, but fastboot remains even if you replace the stock recovery with a custom one such as TWRP or ClockworkMod.

Galaxy s4 compatible sdcards
I'm thinking about buying this:
http://www.amazon.com/PNY-Elite-Performance-256GB-Speed/dp/B00FF90EZM/ref=sr_1_3?s=pc&ie=UTF8&qid=1417386617&sr=1-3&keywords=sd+card
Is the 256gb  compatible with galaxy s4? I'm concerned that it might not be because I've never heard of anyone using such a high gb card with the s4.
Thanks

I think you want a micro sd card. Not the one you chose.

@rrirower Ahh cool. http://www.amazon.com/Samsung-Class-Adapter-MB-MP64DA-AM/dp/B00IVPU7AO/ref=sr_1_1?s=pc&ie=UTF8&qid=1417400166&sr=1-1&keywords=micro+sd So something like this would be good?

Exactly. But, I'd save some money by going with a 16gb card. That's usually sufficient.

I just put a 256gb micro sd in mine today, it works so far. But it has to be a micro sd not the one you have a link to. I've been trying to look up what the galaxy 4 can support, to see if I'll have problems as I fill it up. Haven't found anything yet.

Wi-Fi cannot turn on! Accidentally deleted /etc/wifi folder
i was trying to enable ad hoc network connection on android and overwriting below folders
/etc/wifi
/etc/dhcpcd
and now my wifi could not turn on. The phone is ADINNO R8, a custom build phone.I could not find its ROM on the internet and most of software does not recognize it.
it runs on 4.2.1 Jelly bean.
tried:

USB internet

USB internet to upgrade firmware within OS(seems to use wifi driver as well which are corrupted, so there is no internet connection)

3rd party fixer

download WiFi fixer and not working

other version/wifi folders

downloaded some WiFi folders people upload on the internet and none of them are working.(maybe because this is a rare custom phone)

Recovery

tried recovery and wipe all data in setting, still no luck, wifi folder still corrupted.
i could think of three methods, both failed.

reflash its OS.(failed as could not find its ROM)
upgrade its OS.(failed as no internet access, WiFi not working)
Replace /etc/wifi found on internet (failed as no compatible version)

is there anyway i could fix it?

Is there an upgrade waiting to be installed even?

Try harder to find firmware images for your phone. A factory reset might not work, as it only wipes data and cache partition. The etc folder is in /system/etc, /etc usually just is a link to /system/etc. Therefore you would need an image of the system partiton.
Well, if you can't find such firmware, it might not be a device thats common used, and therefore - if you are lucky - there was not a lot of money around for software adaptations from the manufacturor. Try to get firmware for similar devices, watch out for the same android version, and second on similar hardware / components. Download these images, unpack them and try to find the needed files.
Maybe you can just grab another device, from a friend or so, and look for the files. You might also consider having a look on aosp and taking the files from there. Watch out for the correct android version.

Thanks for commenting. However, as Armando Gonzalez said, there is really not much information for the mentioned phone model...and it consist of 7 hardware button and 3 touch screen buttons. It's really hard really hard to find similar firmware as well... I will keep trying though.

As harder it is to find it, as closer it might be to the official aosp, Android OpenSource Project. The source can also easily be searched on androidxref.com. good luck.

Contact someone from the review of this phone and ask him if he can do a /system/etc  backup and upload it to the internet.Than just restore it.

This is really a comment, not an answer. With a bit more rep, you will be able to post comments.

I'm sorry but i don't have that many reputation, cause i just registered so it would be helpful if someone helps me get it not down voting cause I can't  comment.

Attempt to do a Factory Reset through Settings. I deleted a system file once and it ended up fixing it although my new experience with Android says it might not work. I couldn't find anything online relating to your phone besides reviews, tests, and things along those lines. You are sort of in a pickle here. I'll try to search more for ya.

Thanks for the searching... tried factory reset through setting. only deleted my user data...Wifi still not fix.

@BuWenliang  same here ;-(

Is there an upgrade waiting to be installed even?
I have 2 ideas:
A: Use bluetooth tethering to your phone to get network access
B: You could install some basic commandline tools (eg. ssh server / socat / brctl / etc) from http://dan.drown.org/android/ and try to get a working connection via Android-Debug-Bridge's integrated portforwarding feature (maybe setting a proxy to this port works)

Thanks for the effort. I tried using inserting a SIM card. There is no update available.

Is there any way to share data(not through cloud) between multiple users in lollipop nexus 4 device
Is there any way to share data(not through cloud) between multiple users in lollipop nexus 4 device, I tried with android/obb and other folders but without any success in lollipop version. Kindly provide a way to share large files, within multiple users, on the same device.

I think the first answer (by June Lau) misses the point - the question was about sharing files between different users on the SAME device. I have been using subdirectories that I created within android/obb with success. In my Nexus 7 tablet the exact path is /storage/emulated/0/Android/obb/. The issue is that the media browser does not see files in there, so that one needs to use some file-manager software (search for 'File Manager' in the play store) to get to the file and start its reproduction from there, or for moving the file into the user's file-system.

This worked for me on Android 7.1 as well. The second user was not seeing the obb folder, so I created it with no problem. When I opened it with the second user, I could see existing content (so it obviously hadn't been newly created, just somehow made visible through that action). Files dropped there were visible to the first user.

Confirm that many file handling/viewing apps ("File Picker" com.android.documentsui, "Gallery" com.android.gallery3d and their alternatives such as com.simplemobiletools.filemanager.pro, com.simplemobiletools.gallery.pro ) are programmed so badly as to ignore access to the obb shared files, needlessly complicating user->user data sharing, despite the way via /data/obb is indeed internally working and the correct way

What sort of files are you trying to share? And how large are they?
Android beam / bluetooth will work, though it may take a while and not give you much feedback of how long it will take.
To do this, tap the 'three dots' on the top right, and select share. There's an option of 'android beam'. Make sure that the receiving phone has their nfc turned on.

High data usage by OS Services (on Nexus 4)
Since the update to Lollipop last week, OS Services on my Nexus 4 has been using a really large amount of my mobile data (when I'm connected to mobile data).

Disabled auto backup
Cancelled auto synch of all my accounts
Cancelled auto upload of any photos / videos

Any idea which OS Service could be using all this data?

Answer without unlocking in android 5.0
I recently upgraded my nexus 4 to android 5.0 (Via OTA update).  Now, for some reason, when I get a phone call the screen is black and I have to

press the power button
ress/swipe the lock icon on the screen
enter my password
swipe right to answer my call.

Before (android 4.4) all I had to do was slide to answer.  How can I get the old functionality back?

Lots of people experiencing problems with Lollipop on Nexus have found that a factory reset fixes them. You might try this too.

oddly my phone crashed, then rebooted, and now it works.  Here's hoping 5.0.1 comes soon and fixes this weird bug.

Try resetting the screen lock on your phone. Worked for me. I have a nexus 4 too.

Have you tried this? This might've suited better as a comment

Options not diplaying in service menu (Samsung Galaxy Ace 2, Android 2.3.6)
I am struggling with very low in-call microphone volume (when I simply record sound it's fine). The common solution seems to require going to [5] AUDIO option in the service menu, but I can only see three items there: [1] DEBUG SCREEN, [2]VERSION INFORMATION and [3] COMMON. I'm using Samsung Galaxy Ace 2, running Android 2.3.6 (Gingerbread). I launch the service menu by dialing ##197328640##.
Does anybody know a different way to get to the service menu AUDIO options or another way to boost in-call microphone volume?

Choose a specific app to open a particular file
I created some e-learning using Articulate Storyline 2 which I want to view on my Samsung Galaxy. The files are physically in my Documents folder. The module is not on the internet - I'm still testing it. The file to run the e-learning module is "story.html." It will - I'm told - run on Android with the use of a free app called Articulate Player - which I have installed. When I attempt to run the "story.html" file I get three options - "HTML Viewer," "File Editor" and "DB Text Editor," none of which work. Articulate Player app is not provided as an option. So how can I choose Articulate Player app to run the "html.story" file?
I've looked in applications manager but there are no options I can see that help.
I must add, please pardon my ignorance as I know next to nothing about mobile phones. I have avoided them like the plague for years and only got this one recently as a matter of necessity. I would be grateful for any help from anyone and thanks for your time.

You can only open files with apps that tell Android they support that kind of file. If the app tells Android it can open that kind of file, it'll show up in the list of possible apps.
If this app you mention can open this kind of file, the developer needs to change the app to tell Android it can do so, by adding an intent filter in its manifest. You should contact the developer and ask them to do so.

Choose "send /share" and select the app you want to open the file with

The story.html file is supposed to open in your normal mobile browser, which will then open the Articulate Player app and load the content. Does the "html viewer" option open the real browser, or is it using a browser inside the file manager app? If the latter, then that's your problem methinks. Try opening the story.html file from Chrome or the stock Browser and see if that works. Also, read this as it explains how the content gets loaded onto the client and may help. BTW, you need to specify AMP support when you published the content or else it won't try to use the player at all.

Thanks to Dan Hulme and apraetor for your responses. Appreciated. To the latter, I know this will sound dumb but how would I open the file in Chrome or navigate to it's location? This android stuff is really new territory for me.

Ah, sorted! Downloaded Open In Browser app which lets me choose which browser I want to open a file. And it now works. Again, thanks for your input as it certainly put me on the right track.

Where can I find my App Folder when connected to Computer?
I need to put a .bak file inside my Application Folder.
I connected my Android Device to my computer via USB, but I cannot locate my App inside any of those folders!
I have unistalled the app and re-installed it again, but still, no folder about it in Nexus7/Android/Data
It is probably a silly question, but I really can't find it. And I need to put those .bak files inside, since they are holding a profile, that needs to be loaded inside my App.
CAREFUL: I am not asking where can I find Files that are stored with the OutputStream - but where the FOLDER of Application is located on the Computer, when the Device is connected to it as Media Storage.

Apps' private data directories aren't visible over the USB connection to your PC. It would complicate error handling in apps a lot if you had to worry about users making unexpected changes to your data files, so Android doesn't let you do this, to make it harder for you to screw up your phone.
You can access them from the phone directly, but only if the phone is rooted. If your phone is rooted, you can access any files, but you have to accept the risk of breaking things (this is why it voids the warranty), and it'll make it a lot harder to get support from app vendors. All the same, this is probably using a sledgehammer to crack a nut, and there's probably an easier way to achieve the thing you're trying to, using the facilities built into the app.

I am open for any suggestion here. I created the App quite some time ago, and its quite a big one, so some root modifications to it wouldn't be nice. But now customers want to have their own "Profile" they created to use with App (their background, button colours, etc.).. it is a bak`file..and I need to include it somehow to my App.

I'm afraid I can't suggest how to add a "profile" feature to your app. For a start, programming questions are off-topic here; and even if they weren't, you haven't given nearly enough information about the app and what you're trying to do.

I think I'll go with rooting of the Device then. Thanks for the answer

I know you can access the app folders (SD/Android/Data) through the Airdroid app - and your browser) but while you can upload files to the folders you can't actually see the files already inside.

@TrishLing They're only the ones on the SD card, which the OP can see through USB only. In this case I think he's trying to access the internal data directory, which you can't access with any app (without root).

@Dan Hulme I don't have an SD card slot in either device I use with Airdroid. But yes, it is in the folder labelled SDCard. But after all that is where /Android/Data is.

Cannot use internal memory partition in my Nextbook 7 16GB tab
I have just purchased a Nextbook 7 16 gb tab. I have installed only a few apps and then got the message of "Insufficient Memory". I looked in the storage section and found the tab has TWO partitions under "Internal Storage" One has space of 0.98GB and another internal storage has 12.22GB. All my apps are installed in the first partition. How to use the larger partition for apps? So far I have been unable to do so. KINDLY HELP!!!

Every user of this tablet is having this issue. The company supposedly put out a firmware fix, but when you download the files to install it, they are corrupted. Which either means they are incompetent or purposely put out files that are corrupt so they can say "oh sorry" and never address the issue. Either way I'm not too optimistic.

How to control which apps has access to my connection?
I'm looking for how to control which application has access to network. In my country it costs bit higher for data connections. I don't have access to wifi networks always when I'm travelling. Sometimes when I try to check my mail by turning my data on I will have to wait till all the new check ins of swarm come in my phone to get loaded my emails. Or sometimes when I try to check in swarm I have to wait till all the mails loaded kind of. How can I limit which application only to use when I try to open my data connection.

I'm using unrooted sony xperia L with jelly bean OS and I cannot root my phone.
Thanks in advance.

Go to settings, data usage. Press the apps you want not to use data, and scroll down and select "Disable background data". Now the app won't connect to the Internet if connected on mobile network or mobile hotspot. Please note that if you open the app, it will be allowed to use your data connection, this is only for background data.

Merged contacts keep separating (Google and LinkedIn)
I’ve got a Nexus 5 with Android 5.0 and after installing some applications handling contacts (Google Contacts, WhatsApp, LinkedIn) I got this terrible mess in my contacts. Thus, I merged some manually, definitely not very systematically. Just to make things clear, the main source of my contacts is my Google account.
The problem is the following: It seems that e.g. the LinkedIn app when automatically syncing its contacts first deletes them all (or what) and then it creates them again. This breaks all the merges that I did before and it is all in vain.
Is there a way how to make this work so that my contacts remain merged/linked/joined?
Thanks for help.

Will debugging damage my battery?
I work as a Android developer and I use my own phone for debugging as well as some other devices. Keeping the phone connected with USB will automatically charge my phone but will my battery be damaged by being connected 8~ hours at night and 8~ hours at work every day?

Well, I don't think so because if I talk about modern smartphones they have IC in place which cuts down the power intelligently and over USB I would say it's pretty much less voltage when compared with charger. So, nope I don't think it would damage your battery !

There are provisions to stop overcharging etc etc, but it will keep the temperature of the battery up, and temperature is the single worst enemy of a battery (outside of something unusual like a fire, explosion, water etc), so I would imagine it will degrade the life of the battery. They have a limited number of charge/discharge cycles, so the fact it is charging to full, depleting a few % and charging again all day won't help. How much effect it actually has; I don't know.

I have used my Nexus 4 for developing and personal usage for about a year and no problem so far.

That's a big "Probably not". Even if you could replace the EXE, you run into the fact that Android hasn't supported Flash officially in a few years.
If you want to just run the SWF's without the EXE, you can still manually install Adobe Flash Player together with SWF Player, but compatibility these days is probably hit-or-miss (mostly misses I believe). If it does work on your device, interactive SWF's may have problems.
But if it's worth a shot, it's worth a shot.

Messaging app (stock) not using full phone number to send text/sms
I am using Android 4.2 Jelly Bean stock Messaging App and the get "message not sent" error whenever I use my contact to send the message.  I noticed that the Messaging App might not be using the full 10 digit number to send the text/sms.  If I manually enter the full number, e.g., 155551234567 then the message is sent successfully.  But if I use the contact then it only shows in the top display that 123-4567 number and then it will fail to send any text/sms.
I am wondering if that is problem and if so how can I set the Messaging App to use the full phone number?  I did not find any setting for this anywhere so far.
Thank you for any help.

I presume you're talking about US numbers? If you haven't tried including a + at the start of numbers saved in your contacts that could be worth doing. +1 555 123 4567 is the international format and may help other apps know where to send your message/call.

Thanks for your reply.  I replied early but don't see it here.  So am doing again.  I already have full phone numbers.
