Google Chrome - Do Incognito tabs automatically delete if phone runs out of battery?
so recently, I was looking through some personal information on another friends Galaxy s4 (running Kit Kat) when the battery went out. Problem was, I was using incognito mode.
My question is, if there are incognito tabs running and the phone runs out of battery, once it is switched on again, does it still re-open the incognito tabs?
Much appreciated,
Jacob

The very purpose of having an Incognito mode would be beaten if those tabs would come back after you restart the Chrome or the device.
Google has the following to say here:
(Emphasis mine)

If you don’t want Google Chrome to save a record of what you visit and download, you can browse the web in incognito mode.
...
Incognito mode opens a new window where you can browse the Internet without Chrome saving the sites you visit.... When you close the tabs, Chrome won’t save the sites you’ve visited.

When browsing in Incognito mode Chrome doesn't record the tabs you visit which means there exists no possibility for a normal user to retrieve  them if the Chrome tries to recover/resume the last browsing session once you boot the device after charging it, in your case.
Whatever you browsed in that mode before the device went dark is lost now.
Though having a clear proof already,  I did test the solution by crashing my device and then launching the Chrome after booting it. Nope, those tabs doesn't show up anywhere.

Android phones hangs -phone hardly usable
I have a moto g2 android phone with 5.0.2 android Lolipop.
It has started to hang so severely that the mobile is almost unusable.
The mobile never really had any hanging issues earlier.All of a sudden this problem popped up.
I tried :

factory resetting the phone
removing sdcard
removing junk files & folders from sdcard & internally memory
I have uninstalled most of the apps.(I have google keep,calender widget & watsapp)

Can this be a hardware issue?
I don't want to root my phone as it is still in warranty.
Please share how can I fix this problem .
Thanks
EDIT

when the problem popped up I was on 5.0.1 lollipop version
There is no common point when my phone freezes
After the rest the, when I linked the google account etc & installed watsapp , hanging problem started . Only when there was a fresh reset & no app or account was added the phone worked fine

"The mobile never really had any hanging issues earlier.All of a sudden this problem popped up." -- in that earlier scenario, was the OS Lollipop or Kitkat? 2) Have you noticed something common when the freeze happens? E.g. You're using some common apps, doing file transfer and more. 3) After factory reset and before re-installing the third party apps does your device freeze?

@Firelord please check the edit for the anwsers . Thanks

WhatsApp may be the problem

You might also consider flashing the factory recovery image. I've had issues with OTA updates causing performance issues, and this fixed it on 2 phones and a tablet. I'm sure Motorola provides instructions but just in case, this XDA guide for restoring stock firmware on Moto G might be helpful.

Update Samsung Galaxy Note 2 to Android Lollipop
Is it possible to update further Samsung Galaxy Note 2 from Android 4.4.2 KitKat to Android 5.0 Lollipop?

If you're open to using custom ROMS: How do I Install a custom ROM/recovery on a Galaxy Note 2? Samsung itself is unlikely to ship such an update (device too old).

Yes it is possible, but it involves installing a custom recovery (TWRP or CWM) and to download and install an AOSP-based ROM. Note that the following links refer to the N7000 model of the Note 2.
Possible Recovery - TWRP
Possible AOSP based ROM

What is the use of Android System WebView?
I have seen some Android phones where this application comes installed on the device. What is the use of this application?
(Click image to enlarge)

Does installing this app have any advantage on any other Android devices which does not have this application installed?

It's been available since Kitkat and the apps which takes advantage of it can open the webpages in themselves (their activities) unlike those which always asks you to open them separately in a browser. E.g. Facebook on Android 4.4 and above loads the external links into itself rather than asking you to open them in a browser. See https://developer.android.com/reference/android/webkit/WebView.html and https://developer.chrome.com/multidevice/webview/overview

The above should be the answer and not a comment.

@Firelord So if I open Fb application and when I click a news article from the application with the help of the Android web view it will open the News article on top of the application and under the task manager it will show only Fb and not the browser through which the news is loaded.

Why cannot we embed default webView in separate fragment or activity and pass url to load in our app itself ?  I have done similar in this GitHub POC - https://github.com/hiteshsahu/Android-Universal-Web-Content-Loader .

Some applications require what is known as WebView, a mini browser for functions like approving logins from Facebook and Google+. This is essentially a miniature version of Chrome.
It used to be that WebView only updated with the OS. In Lollipop, Google detached it from the Core OS in a way, and added the functionality for it to be updated via Google Play, like other apps, automatically. This allows it to keep up with Chrome and provide a better browsing experience.
The next time you log into an app and you are brought to a Web Page in the app saying "Allow 'The App' to assess your Google Account" or what not, see if you get get to the Google homepage via the "About Google" link. Then search for and open http://WhatBrowser.Org You will see how it is a mini chrome-based browser inside the app, provided by the system, and updated by Google Play.
Having this installed will keep it updated. You will not have to wait to upgrade the Android OS.

Probably one of the best reason why WebView update is now independent of Android OS is because of WebView vulnerability on Android 4.3 and before. With the update being independent, the vulnerability can be fixed without the need to wait for OS update (though it's only for Android 5.0 and later).

I don't use Chrome Browser,Google+ and Facebook. I have disabled these apps. Should I disable Android System Webview app too?

means do I need Android System Webview app?

"I don't use Chrome Browser,Google+ and Facebook. I have disabled these apps. Should I disable Android System Webview app too?" --- Some applications, other than those you mentioned, use WebView. I suggest you leave it on. There used to be a vulnerability in the previous version of WebView but this has been fixed from 4.4 onwards (at this point WebView changed and is based on Chromium). From 5.5 onwards, WebView became an independent component from the OS and thus appears as an application.

How is an Android N based device despite having it disabled is able to open webpages within the respective app

@user285oo6 From Android N, there is no more need for the System Webview. Chrome is used directly by embedding apps instead.

missing glyphs on web pages
I have a rooted Galaxy Note Pro.
I'm annoyed at black blocks that appear instead of whatever symbol, when reading web pages.  I copied Code2000, Symbola, and the BMP Fallback ttf files to /system/fonts, but (e.g. https://en.m.wikiversity.org/wiki/Reed%E2%80%93Solomon_codes_for_coders#Finite_field_arithmetic ) I still see a block instead of the symbols for Real and Integer domains.  This test page shows lots of blocks in Firefox. The Android browser simply skipps them instead. I also tried Opera.
Is there something needed to register ttf files, other than copying them to the directory? ( Total Commander remounts the file system r/w ) and rebooting?
It's annoying that I can display Tamil, Myanmar-extended-A, and other things I can't actually read, but am missing symbols and marks that appear in pages I do wish to read.

Android keeps track of fallback fonts via a file at /etc/fallback_fonts.xml. After adding your fonts to /system/fonts, you can add a new family node to the XML file like this.
<familyset>
    <family>
        <fileset>
            <file>Custom-Font.ttf</file>
            <file>Another-Custom-Font.ttf</file>
        </fileset>
    </family>
[rest of file...]

Make sure to make a backup first, and you might need to reboot for it to take effect completely.

Very interesting!  I see there is also a file fallback_fonts_sbrowser.xml but the comments in it are just the same. What's that for?

@JDługosz I don't know what that file is for. My phone doesn't have it. Maybe it's some sort of extra customization or testing done by your phone's manufacturer or carrier? The comments at the start of my phone's *_fonts.xml files both refer to an optional /vendor/etc/fallback_fonts.xml file, but that's it.

FWIW, I’ve still never gotten it to work.

Extracting data from running app’s memory address space
Note: the original problem was solved in another way.
Can Ī̲ access memory of an app without (already obtained) root to extract some lost data? A weaker version: can Ī̲ see which files does the app access? Or, possibly, looking in the file system’s deleted/unused space would provide better chances? To be specific:

the device is Explay sQuad 7.82 3G
the OS is Android 4.2.2 kernel 3.4.5 (the one supplied by manufacturer)
the app has the word “Tips” on its icon (its name is presumedly “com.mediatek.notebook”; it has android.permission.READ_NOTEBOOK and android.permission.WRITE_NOTEBOOK permissions)

My problem is trying to recover a chunk of text lost after some UI glitch and recklessly pressed back (↶) that caused the crappy software to save the damaged record. The text in question was saved many times during several days and lost just before Ī̲ stood for copying-and-pasting it to ssh client’s window. Any help will be appreciated; just note that Ī̲ have fairly strong skills locating and extracting various data from memory dumps, but am not a frequent Android user.

Update: Ī̲ rooted the device via USB using instructions from there and there, located the process, and entered its /proc/pid. The system even has gdbserver already installed. Now what?

Update: Found all data needed in files in /data/data/com.mediatek.notebook/databases/ and am not very interested in obtaining memory dumps.

You said you copy/pasted text to ssh client window. So it will be easy to ssh  again into a machine and see history of commands :D really bad if you need to recover a piece of text. The worse case is that text containing login credentials for ssh. Anyway, try with eclipse and see in logcat what app do (there are chances  to find  explicit location for files used).

If you think app store files on sd card, there are chances to recover deleted file via sd card adapter and pc... (if you're on windows, there are some programs running (free) to recover under an amount of data (let's say 100 mb I don't really remember what was the cap/limit for  easeus Free SD Card Data Recovery). Also read http://stackoverflow.com/questions/9017073/is-it-possible-to-see-application-data-from-adb-shell-the-same-way-i-see-it-moun ...and now a question :D did you manage to dump memory from ms-dos games in your life?  you know, full dump breaking the 500 k limit of mem.process :D

@user3344236 is sd card the thing accessible through USB as a VFAT storage? No, it’s unlikely the data in question were ever written there.

transfer contacts from sd card to computer via USB
Is it possible to transfer my contacts from a TMobile Concord Android sd card to my PC?  I have a USB cord.  I know the way to transfer it to Google, but this is my old phone with no service or connection.  I also have an Alcatel One Touch Fierce 2 that has some of my updated contacts on a SIM card (SIM won't stay in place because the metal piece that holds it broke off)  Again, no internet connection.  My new phone is an Iphone5c and I need to get those in there somehow.

Pretty easy to do, and probably explained in some other answers here already:

Open the Contacts app
Hit the Menu button/key, and chose "Export/Import"
Select "Export to SD card" (creates a file named something like 0001.vcf in the root of your SD card)
Either shutdown your phone and connect the SD card to your computer with a card reader, or connect the phone via USB (storage should show up there then)
copy the 0001.vcf file to your computer

*.vcf is a file in VCard format and can be read by many applications. So you can import it into the software of your choice (or transfer it to your new device to be imported there) and check whether all contacts came along. In case the SIM contacts are missing, you might need to first copy them into your device's own contacts.

Oppo find 7: bootloader re-lock impossible?
I tried to relock the bootloader on my Find 7 (which I'm pretty sure was unlocked since I installed a custom rom).
fastboot oem lock
...

After that nothing. Windows console is "stuck".
Any clue?

Just to gauge what you've done, is your device discoverable via adb while its on? If so, then run adb reboot bootloader, which should then boot to fastboot mode. Alternatively it might appear as a selectable option using hw keys. Once in fastboot mode, run fastboot devices to see if its recognized.

fastboot works. and fastboot devices shows my device

I see the same behavior on my Find 7.  I also seem to recall the device arriving unlocked.  As far as I can tell, it simply does not support locking the bootloader.
Running unlock just instantly says OK despite the fact that Developer Options does not contain the "Enable OEM Lock" setting at all (on the latest ColorOS 2.1.5i software, which is Android 5.0 — the version where that feature was added).  I also cannot find anything about (un)locking the Find 7's bootloader online other than one obscure Thai site that seems like it is probably trying to get clicks by reposting the same instructions for multiple devices.

Unbrick SpreadTrum based Android phone (Micromax Bolt A27)
I have a low end device i.e Micromax a27(SpreadTrum SC6820) which I m trying to restore after I had rooted it and tried to free up some space by removing the apps which broke the phone's OS.
Mistakenly I also executed a command in fastboot mode that flashed the system with a recovery.img(fastboot flash system recovery.img) after which the phone keeps on buzzing infinitely and nothing shows up on the screen.
I then tried to follow this method http://androidxda.com/flash-pac-stock-rom-android-smartphone but the phone starts buzzing endlessly when plugged in with a USB cable and nothing is shown in the status panel of tool mentioned in it (UpgradeDownload.exe)
This tool seems to extract the .img files from the .pac package(present under the firmware folder of the downloaded stock ROM) and place it in the phone,Can I somehow extract them from .pac and place them manually in the phone via fastboot?

Download research download tools, load the pac file and go in settings there you must see alls files into the pac, now it's very important: double click on system location and copy, go in your file manager, enable hidden files and paste what you have copy in file location bar in your file manager you will see all needed files

What is "research download tools"?

How do I install an OEM's launcher in my device?
I can easily install launchers available in the market like Nova launcher and others but not the launchers made by many OEMs (e.g. TouchWiz, Optimus UI, Xperia UI, Sense UI, Emotion UI by Huawei, MIUI by Xiaomi, Zen UI by Asus, Color OS by Oppo and the Cyanogen).
Anyone having a device made by those OEMs should be able to upload the APK of their launcher, so why it is not possible to install them? As an example, see How to download and install Samsung TouchWiz launcher any Android device?
A good detailed explanation would be appreciated.

The apps made by OEM are specific to their devices and ROMs.
The apps may depend upon external libraries that the phones don't have..

Anyone having a device made by those OEMs should be able to upload the APK of their launcher, so why it is not possible to install them? As an example, see How to download and install Samsung TouchWiz launcher any Android device?

You can directly install the APK, but it won't work.
Because, you need to place the lib files in the /system partition necessary for that app.
That's what flashing the zip file does :)
The only way to get it working on other devices is porting the app by editing and linking the necessary library files.

Can I change the font color of my Google Now card?
So in the From and Arriving on my Google now time cards, the values I put in are white. Which makes them unreadable.

Is there some way that I can change the text or card color so it is actually visible?
Thanks

I had the same issue, but it was fixed with the most recent Google Search update (I'm currently on version: 5.1.17.19.arm)

It must have updated yesterday on my phone, it is now looking good. Thanks.

Try to uninstall updates of Google Search, and see if it works.

If you mean the "Google App", I can't. When I go into the App info of it, the Uninstall Updates is grayed out.

Why would external Storage Location be unavailable in Play Music and Play Movies?
I have a Galaxy Tab S running Android 5.0.2. I also have a 32GB SD card installed. Supposedly I should be able to set Play Music and Play Movies to download to the external card, but those options are not available for some reason.
In Play Music Settings, I see the Storage location option, but it's set to "Internal (on this device)" and it is disabled (greyed out); tapping does nothing to change it. In Play Movies, there is no option at all in Settings nor when I tap to download a rented or purchased movie.
I see plenty of referneces online about people being able to set the storage location for both apps, as of Android 4.4 and above, so I'm confused why I can't get it on my Lollipop 5.0.2 tablet.
I've confirmed that I can write to the SD card; I've done so via the Android File Transfer app from my laptop, as well as using the Samsung My File app installed on the tablet.
Update: I just noticed that this happens only for some of the user profiles on the device. The "owner" profile can set the storage locations to external (SD card) but no other user profile can.

I had a similar problem on my Lenovo P70A on Android 4.4 and 5.x as well.
The solution for me was to manually create the folder "com.google.android.music" under the "/Android/data" folder on my external SD card, which is where Google Play Music normally stores the downloaded (offline) music. Once I've done this and force closed Google Play Music, starting it again it resulted in the External Storage option becoming available.

Doesn't work for me. How is your sdcard called? Mine is /Removable/MicroSD

What does app not installed mean?
When I try to install an update on angrybirds epic rpg,it says "app not installed" what does that mean?It takes up 105.9 mb I have 500 mb left on my device.I have an android tablet.

I think you should edit and reflect the actual issue and the steps you took to trace the issue. "App not installed" means the app did not install. It's quite plain to understand. What you should be asking (IMO) is how do I know why the app did not install?

If I get you correcty then your tablet has the app already installed and all you want to do is to install an update from the Playstore. So why is your Tablet not recognizing the app as installed? Please go to settings - apps - angry birds epic and see if you can "move it to the tablet". I think it has downloaded the assets to the sd-card and somehow doesn't recognize it anymore.

It can mean many reasons, maybe out of memory, incompatible app, problems to your ROM, conflicting currently installed apps and etc.
Maybe you can try booting your phone to safe mode to remove conflicting apps . You can also try rebooting your phone.
Hope this may help!

That helped a lot thnx guys

Will LG Optimus Exceed update to Lollipop?
The LG Optimus Exceed ships with KitKat 4.4.2. Will that automatically update to Lollipop, or would I need to root the phone?

When will my device get the Android 5.0 update (Lollipop)?

A quick search on Google doesn't show any result if the device will be updated to Lollipop, so we can only guess "no", unless there's official announcement from LG itself. Rooting the phone itself won't help if there's no custom ROM based on Lollipop for this device too.

How to install apk in 2nd user of android 5.0 without playstore
So, android 5.0.2 doesn't allow side loading of apks for 2nd user (irrespective of whether it is guest or standard user). "Unknown Sources" is disabled and is uncheckable. And I use a pure Cyanogen Mod 12 (android 5.0.2) without any Google apps. So, there is no Play Store app.
But I have root access.
As shown in the pics, Unknown Sources is Uncheckable and installation is blocked.
(Click image to enlarge)

With this situation, how can i install apks on to the 2nd user account??
EDIT:
It seems Google intentionally (in the name of security) blocked sideloading apks for 2nd user in android 5.0.2. There is a bug report here. And sideloading was reenabled in android 5.1.
I will post how to sideload apks on lolipop 2nd user using adb. If this can be done without adb please post.

enable sideloading

How? Unknown sources is untickable in 2nd user in lolipop 5.0.2 .

amd first user? I think it's untickable because the main user has disabled it. so any other user can't active it

Main user has it enabled. 2nd user has only option to install apps from play store. Device without gapps are affected...

it's working on cm 12.1. I tried it right now.

@Schwertspize CM12.1 runs Android 5.1.x while OP noted Android 5.0.2 (CM12). I got confused first too but later amended my answer. :)

@Firelord I know that cm 12.1 is based on android 5.1. I just tried it and wanted to share that it's cm 12 only.

Using the command,
adb install -r whatever.apk

will install the application in 2nd user of android 5.0.2 .
Source

what if the 2nd user can't enable developer options and so can't enable usb debugging ?

2nd user cannot enable developer options and usb debugging. When 1st user enables usb debugging and installs this way, the application will appear to 2nd user. If 1st user willingly disables usb debugging, then there is nothing much 2nd user can do in this regard..

If settings.apk is recompiled with this (https://github.com/CyanogenMod/android_packages_apps_Settings/commit/338ab4561d7e06619b43f3634be7414afe5389d1) commit or this (https://android.googlesource.com/platform/packages/apps/Settings/+/ceceb2a) included, then it will be fixed.

Is there a way without need to use ADB? Any method that might require root or custom recovery maybe?

I don't know because I panicked and came away straight away tell me how to find it and I'll get it once u can help to get rid

I think this question was asked before by you. It's not a virus. Websites use pop ups to redirect you to malware sites or to third party app pages. I've already told you to use Firefox browser and it's add-on AdBlock Plus.

As @Mani said. There are millions of sites out there that have all kinds of popups trying to scare you and trying to get you to install rogue software. Seeing how you said you have factory reset the device. Is it only when you goto that site or any site? I tried both sites with and without ad blocker and they just seem to endlessly redirect. I am wondering, If they are targeting an exploit that might be in the HTC One? Also when you did the factory resets, did you reinstall all the apps you had before? Cause one of them could be malware and causing this to popup.

@jer3my I downloaded some eg facebook snapchat 1game and a few anti virus apps. How else will I get rid of it if that app don't work

It is a Spam and it has nothing to do with your Mobile phone.
There are many websites out there that use these tactics to persuade users to click on malicious link.

Please do not click on "Remove risks now"
Avoid visiting such links as much as possible
Also, install Adblock plus

As of the website, Scamadviser (it reports on the safety of web sites by crawling the web and testing the sites it finds for malware and spam) mentions here,

It is 58 days old (as of September 14, 2015) and has a life expectancy of less than a year, which probably means it is a scam website changing its domain every now.
The owner of the website is using a service to hide their identity.
(Some owners do not wish to receive any spam, so they conceal their identity but many scam sites use this as a method to hide their identify)

Can I get rid of it or block it I don't understand all the computer terms I feel like selling my phone

Just install this https://adblockplus.org/android-install

Simply put,  If you visit those sites in any of the phones, you'll get the same pop-up. It doesn;t mean all those phones are infected. Just install Ad-Block. It will go away.

It's coming up an app like this could infect my phone will it tho

Do not panic. They are all ad-s to make you click on their malicious links and make you intsall their fake/spam apps.

What do I do when I install all this

I can't open it is there one in the app store

It is not there in playstore. Install directly from the given link in browser.( Before doing it, Goto settings> Security>Unknown Sources> Allow)

Ya know this thing on my phone why is it going to others phones in the house

If something tells you "there's a VIRUS on your Android phone" – be sure it is scam. There are no viruses for Android. You know why penguins and ice-bears can neither be friends nor foes? In nature, they never meet (the bear lives in the north, the penguin in the south). Same with Android and viruses. Stop visiting that zoo (ahem, site), and your issue will be gone.

@Izzy well said! Yes there is no virus for android. It's based on Linux which is one important reason to have no virus problems. Antivirus apps are just for satisfaction that you are protected from spam.

Additionally, @manubhargav, you might want to mention the fact that the owner "hides its identity" (btw: very good find with the scamadviser site, which says this – just upvoted your answer). With the context of the other data, this makes your conclusion (which I share) even more likely.

@manubhargav you might wish to include that with your answer (and we remove these 3 comments then) – cleaner, easier to see – and nobody checks "down here" :)

how do I remove a missed call notification?
I don't want to disable missed call notifications
And I don't have a "locked screen".
Somebody called me, I missed the call but I met them. I don't need to call them back, so I don't want to tap the missed call notification('cos I guess that'd call them back). How do I remove the notification without calling them back?

You can tap it, it won't call them.
It just goes to the screen with telephone numbers on it.
Another thing you can do, is in the notifications where it lists the missed call , then the first time round, it can also show "call back" and "message"  so you have 3 things you can push. The missed call , which goes to the numbers screen. Or the other two. So only one of those options will call them back. Once you restart the phone you still get the missed call notification but without those other options, still though, if you tap it it goes to the numbers screen, it doesn't immediately call them back.
It's not as bad as with tapping a number on the number screen, where if they're listed under "frequently called" then it calls them immediately, whereas if you tap them under the purely alphabetical list below "frequently called" then it brings up their details from which you can call them.
So tapping the missed call notification won't call them automatically
You can swipe it too, though I suppose swiping might involve a tap, but a tap is fine.

Disable touchscreen input via console
I'm looking for a way to disable and enable the phone's touchscreen via console, and possibly the physical buttons, so to prevent finger touches from being processed. The phone is a Samsung Galaxy Fame, Android 4.1.x.
Background:
I'm configuring an old Galaxy Fame to serve as a sat navigator fixed on my car dashboard, aiming at using the up-to-date and free OpenStreetMap.
When I turn the key, the phone's USB is powered at 5V, when I turn off the car, the USB has no power. The phone is able to detect these events and I scripted some actions upon them, aiming at providing an instant-on and instant-off navigator service.
The phone remains always on and just switches to a power-save status when the car is off. The navigator app – OsmAnd – starts automatically at boot, but the boot does not occur between a car-on / car-off cycle, because the phone remains on to detect the mentioned USB changes.
Currently, what happens when I start the car and the USB gets powered:

Display is lit (echo 200 >/sys/class/backlight/panel/brightness)
Sat receiver is activated
CPU frequency set to max

What happens when I turn off the car and USB loses power:

Display's backlight off
The sat receiver goes off, along with WiFi and Bluetooth, in case they might have been active
CPU frequency set to minimum

Up to this point, everything is working. My problem now is that, when the car goes off and the phone enters this quasi-standby mode, the touchscreen still accepts input and, if the phone is handled or touched for whatever reason, it will stealthily react to those touches while the screen is unlit.

what is the model id of this device? meaning sm-blahblah , also can you post your init.rc to a pastebin? You have this device rooted?, grep your ramdisk *.rc's the perms/chown entries should tsp-ish, touch screen panel

run cat /sys/class/sec/sec_touchscreen/set_module_off
if it comes back 0 then echo it to 1 and see what happens.
Also how do i wrap code in comments?

This is a "Samsung Galaxy Fame gt-s6810p"; /init.rc is here: https://pastebin.mozilla.org/8842877 ; the device is rooted and I can execute su; grep results look interesting but I have not yet experimented with these control files: https://pastebin.mozilla.org/8842878 . My fiddlings with /sys/class/sec/sec_touchscreen/set_module_off are here: https://pastebin.mozilla.org/8842879

okay, that's a classic mistake, it's a good thing anything you do at the moment is temporary, cat FIRST to find out if it's  a 0 or 1 type of setting.

cat your init.rc and under # Permissions for InputDevices.
chown system radio /sys/class/sec/tsp/cmd
chmod 0660 /sys/class/sec/tsp/input/enabled  <--your device may differ
chown system system /sys/class/sec/tsp/input/enabled <--your device may differ

Add to your scripting setup after verifying, for my device, a Samsung Galaxy Tab 4
echo 0 > /sys/class/sec/tsp/input/enabled

Touchscreen disabled.
echo 1 > /sys/class/sec/tsp/input/enabled

Touchscreen re-enabled.

Cool to hear! My phone however doesn't have that control file. The closest things I can approach to by grep-ping under /sys for the strings enable and tsp are: /sys/devices/virtual/sec/tsp/power/autosuspend_delay_ms — which I ignorantly overwrote to 1000, to no avail, and /sys/module/hid_prodikeys/parameters/enable, which I overwrote to N,N,N,N,N,N,N,N attempting to disable the touchkeys, to no avail. Write permissions were set before each write, and no errors prompted. I was probably deceived by the name of those control files.

I also tried fiddling with /sys/class/sec/sec_touchscreen/set_module_off and /sys/module/hid_magicmouse/parameters/report_touches.

I found a solution from https://android.stackexchange.com/a/193667
rm -rf /dev/input/event0

Does "delete" my touchscreen input. The other events disable/delete my other hardware buttons like volume etc. After restart of the phone, they are back.
You need root / su for this.

On Google Nexus 4 (mako, LineageOS 14.1) and Xiaomi Mi5 (gemini), you can give
rm /dev/input/event2

to disable the touchscreen at runtime. You will still be able to control the device through scrcpy.
On Google Nexus 5 (hammerhead, LineageOS 14.1) you can give
rm /dev/input/event1

Is it possible to wipe data from ADB without turning on USB debugging?
I'm on manjaro Linux. A friend of mine broke the screen of his note 3, it's working, the screen stays black though.
He wants to get all his data from it and format it, wipe everything, he's not going to fix it.
The back up part is easy, I plug it into my computer and take everything. But is it possible to format it without turning on the USB debugging? I bet the USB debugging on his phone is turned off and I can't turn it on without being able to see anything on his phone. So as far as I know I can't use ABD, can I?

Without enabling USB debugging I doubt the adbd (ADB daemon) is running, so I don't think it's possible.

@GiantTree I'm going to try https://www.youtube.com/watch?v=B7Z_r0Z0CEo

Could download a custom recovery for the device and flash it via odin. I think Clockwork mod has adb built into it. Then you can run the commands that way... In theory. Lol

@jer3my without usb debugging enabled? AFAIK odin won't work if usb debugging ain't enabled

@Lynob. As far as I know, odin doesn't require USB debugging. It doesn't need it when the phone is in download mode.

@jer3my good idea, please leave an answer, I'll vote it up now and accept it on monday if it works, cause monday I'll try to do that.

Could try downloading a custom recovery, such as Clockworkmod for the device and flash it via odin. I think Clockwork mod has adb shell built into it. Then you can run the commands that way. And as far as I know, odin doesn't require USB debugging. It doesn't need it when the phone is in download mode.

To my knowledge if you do not have USB debugging ADB is not running and any tools that rely on ADB will fail to work.

since i'm not able to comment, i'll make an answer. i've been in this exact spot with this device before. you won't be able to flash the recovery w/o  triggering knox and voiding the warranty. if that's not a concern, you should be in the clear. keep in mind, you could lose the data at any point in the process. samsung has notoriously unreliable USB controllers and if they decided to stop working, the data is probably lost. don't use odin, use heimdall. here's a guide:

Is there a way to permanently clear all notifications and mark them as "read" from the lock screen or notification menu?
Background: I often get no signal on my phone, so use apps like Airdroid and O2 TuGo which allow for texting and calling over wifi and from multiple devices.
The problem is, when I get my signal back, I suddenly get a flood of text messages which take a long time to individually mark as read. I also get message/call notifications from apps like TuGo even if I've already read the message from another device such as a desktop PC or tablet.
Is there a way I can permanently clear the notifications, preferably from the lock screen and/or the notifications bar?
A search leads to this question but it only applies to SMS messages, not other notifications.
Android's own "clear all" button does not mark notifications as read, it only temporarily removes them which is pretty useless.

Marking texts as read is a per-app thing, so there's no standard way to do it. By 'permanently' clearing notifications, do you mean disabling all notifications entirely (for a period of time or for ever)?

@JoshHolland I meant clearing only that instance of a notification permanently. E.g. banish a missed call alert, but don't forbid any more missed call alerts from occuring in the future.

I have some solutions.

To avoid apps permanently not to display in notification bar.

Go in app info of particular app and disable show notifications.

To read all SMS at once.

Install Tetra SMS from play store .This app gives option to mark as read to all SMS

Could you link the app?

Spell Check not working on HTC M9
I was wondering is spell check on android the same as the iPhone, that is does the word get underlined, because that doesn't to be happening in my case. I have downloaded Swiftkey and Google Keyboard and both still don't have that option, is there anything I can do? I don't want next word/current word prediction!

It does work, not sure on your device but on the Nexus 6 running 5.1.1 under Settings > Language and Input. There is an option for spell check. I use the Google keyboard and I assure you. It has spell check. It's in the keyboard settings under text correction.

it seemed to be working for SMS, but not on twitter & other apps :/

Try this. https://productforums.google.com/d/msg/hangouts/2HZOEgILrsg/0IXxuFAFyY8J I know he is talking about hangouts but maybe it has the same effect on other apps.

Yureka fastboot not detected in LINUX, but adb detects device
fastboot detects Redmi 2, but not Yureka.
I am trying to install Cyanogenmod in Yu Yureka. When I tried installing the CM zip with default recovery, it failed stating "Signature Verification Failed".
So I tried to install the TWRP recovery using fastboot. I did the following:

I get the fastboot screen on Yureka device, but no luck with fastboot devices.
(Click image to enlarge)

Some suggested that running fastboot as root user solved this. But that too didn't work for me. But for Redmi 2, I was successfully able to install TWRP recovery using fastboot, so that makes fastboot works, but not for Yureka.
I am using Ubuntu 14.04.

Do you need to add udev usb rule for yureka?

@moonbutt74 I've already added the udev rules file from android website, and that contained the yureka's vendorid. Please see the pasted content. The Bus 001 Device 004: ID 05c6:9039 Qualcomm, Inc. is the Yureka device and the vendor id "05c6" is present in the rules file

Kenpachi, it may be that you are not in fastboot mode, meaning  ' adb reboot bootloder ' hasn't actually put you in fastboot mode. i don't know what model you actually have but follow the guide here concerning booting the device into fastboot mode then check your read again,
http://forum.xda-developers.com/yureka/orig-development/recovery-cwm-based-recovery-v6-0-5-1-t3001339

@moonbutt74 To unlock the bootloader, I must gain access to fastboot. BTW I get the Fastboot screen, but fastboot devices does not list the device

hmm okay take a look at this -- adb-fastboot-install
https://code.google.com/p/adb-fastboot-install/
Still not sure if it's the device or linux

In the recommended ways to boot the yureka into fastboot mode, abd reboot bootloader is not among them, Method 1 is enable developer options and enable advanced reboot options, plug in phone to pc and then select bootloader from the reboot menu, and Method B is outline in the XDA link. The only thing i can see is a duplicate group entry in your rules. Is that correct?

@moonbutt74 I tried that method as well. Held the Volume up button after connecting it to the PC, I get the same screen as when using adb reboot bootloader. Then tried using fastboot devices. No change there as well.

can you run chmod a+r  on 51-android.rules and then run fastboot again? all the information i can find is for windows, with one linux suggestion to update fastboot. Are your sure your vendor id is correct?

Yureka requires the vendor ID as a parameter for fastboot.
Try the following (tested on Yureka Plus):
% lsusb
Bus 003 Device 003: ID 1ebf:7001

% fastboot -i 0x1ebf devices

Try this command for Yu Yureka
sudo fastboot -i 0x17ef devices

Android storage with UTC timestamps?
I would like to use UTC timestamps on the FAT partition on my Android phone.
Reason:
When one moves files from an Android phone to a Linux desktop, one gets wrong timestamps for files which were modified during daylight saving time. The FAT driver on Linux converts the local timestamps from the FAT partition to UTC timestamps on the desktop. It cannot handle daylight saving time, though.
There is an option tz=UTC to mount on Linux to skip this conversion, i.e. to assume that the timestamps were in UTC on the FAT partition.
Consequently, a way to get around the problem would be to use a similar option on Android to use UTC timestamps on the Android storage.
Is that possible?

What does "encrypt all outgoing email" really mean?
I have a Samsung Galaxy Stardust with Android 4.3.  In the email app, under security options, there is an option that says "encrypt all outgoing email".  But my understanding of S/MIME is that in order to encrypt e-mail to someone, I have to have their public key.  So it seems like this option can't really do what it says it does.

It likely means to use SMTPS, not S/MIME or S/GPG.

@LieRyan, when you set up a mail account, there are settings for communicating with the mail server with SSL, so if "encrypt all outgoing email" meant the same thing, that would be redundant.

It actually gets the public key of the receiver before sending the email. So yes, it could do what it says.

Gets the public key how?  Unless that person has already sent me a signed message, I don't see how it would be able to get the public key.

Saving image out of Google app
I can't find a way to get an option to save an image out of the Google app on my phone? I open the image and after going through enough many steps to call it awful UX, I get to these menu options which offers sharing but not saving:

Is it purposely designed to make saving images difficult or impossible?

By "Google" app, did you mean Google search? If it's, then you have to open its website first on the browser, then you should be possible to save it from browser (e.g. by long-pressing the image)

Do you know what the reasoning is behind such awful UX ? Why didn't they design it to make that function more easily accessible?

Yes , Google search app

How do I know if a replacement screen is dead on arrival?
I dropped and broke my One Plus One's screen and subsequently replaced the screen/digitizer. However, there is a vertical strip on the screen where touch is not sensed properly. Before I replaced the screen, the areas where touch did not work was completely different on the original broken screen. What would be a way for me determine if this is an issue with my dis-assembly/assembly or if the replacement screen I got was already broken (dead on arrival)?
The replacement screen was this one.

did you find an answer for this?

I just posted what I did in the end.

I tested the screen by plugging it in after disassembling my one plus one but not using any of the adhesives yet.

Two phones appearing on android device manager
I lost my phone last month and was desperately looking for ways to track it. I never installed any apps to track it and so I got online to see if there were other options and found 'Android Device Manager'. After the remote download, I tried locating it, but then the internet was turned off and a few days later with no success, I decided to go for the factory reset. I was talking with a friend today and he told me that, he got a call from someone saying I had given that person his number, so I decided to get on ADM to see if I could maybe track it this time or check what was going on. To my surprise, I now see two phones listed under my account. I have not bought a new phone yet. I am just wondering why does it show another phone under my account.

the factory reset was most likely successful. i'm guessing the twin devices are showing different locations and one or both never move and may show as offline (if both are offline, dead battery). the device is linked to ADM via your google account and an ID generated when android boots up for the first time. after the remote reset, the device will boot, generate the new ID and ask for the password to the google account the device is linked to. as a ROM addict, i know this all too well. there have been times i've flashed 10 ROMs in a day. i used up my device removal limit on google play music very quickly.

The other phone that's linked to my account is a Samsung phone (GT-I9500). It says registered July 31, 2015(Online; Google location is turned off. Last online August 14, 2015) and my Sony one shows location unavailable; Last online July 22, 2015.

oh, so it isn't a twin. if you haven't already, change your google account password.

my edit was because i tested it out on my device and found out that it wasn't IMEI, but that a remote wipe remembers the last known google account and keeps the device locked until the password is entered.

Okay, so the password has been changed. Now, when I hit locate device, it hovers over west Africa.

one of 2 things happened. your sony device went dead where you lost it and somebody has you google account login or somebody stole your sony device, dumped the data, grabbed your google account login and used it on a new device. there might be other reasons, but they're obscure and would require a lot of skill and knowledge to pull off.

it's hovering because that samsung is now showing a notification that says your google account needs to be re-authenticated and the account won't send or receive data on that device until the user puts in the new password. it will disappear from ADM if the user removes your account from the device.

It did even before the password change. I am not sure if that's the default location it goes if the location is turned off.

yea, that's where it goes if it has no location data. somewhere in libya.

either way, that device that isn't yours won't be able to access your account now. you may want to look into 2 step login verification for your google account now. 2 step login requires a password and a randomly generated code sent to you via text or the google authenticator app. you'll want to make sure you're using the second one so the other user doesn't get sent the same codes.

Hmm.. Thanks a lot for your time. I was bit perturbed, when my friend asked me, if I had given his number to anyone, so decided to check what was happening.

yea, that's upsetting. you're very welcome. stay safe.

Unable to connect to wifi router: Something wrong with configuration?
I needed some way to interact between my desktop and my android phone (Cynaogen). I got a router from my friend. To be clear, its not about getting access to internet, I just want to establish LAN connection between by desktop and Android phone.
By logging into the router, I've configured "Wireless Network" to following settings (advanced view).
Problem is even though XYZ wifi network is shown in  available networks in Android phone, after entering the password, status is turning to Saved and after  a while it says Authentication Problem.  I tried rebooting the router, forgetting the network and try connecting again in my phone. I tried connecting using my friend's phone (kitkat 4.4) too. But still it isn't connecting.

TTS speech from console
Can I synthesize arbitrary text strings with TTS from the Android's console?
To give the idea, on Debian I would do:
festival --tts <(echo Buongiorno signore)

The TTS engine needs to be always available and run offline, thus Google TTS is not an option. The phone is a "Samsung Galaxy Fame gt-s6810p" with Android 4.1.2; it comes with an offline Samsung TTS engine installed.

I normally run android tts from android terminal, just the way on linux.
I achieve this with sl4a & Python4Android (github.com/kuri65536/python-for-android/releases).
Here is the wrapper script that I use for python environment in terminal.
Just Create a python program using sl4a tts api, like this ::
`#!/system/bin/py  # Change the Path to wrapper script

 import android
 import sys

 droid = android.Android()

 print 'Speaking ::' + sys.argv[1]
 droid.ttsSpeak(sys.argv[1])

`
Save as tts. Run it in terminal with your text as argument.
tts 'Hello, It's me TTS , running from console.'

Lan local ip address of Android phone is constantly changing?
I believe I am a victim of malware on my phone.
I have already flashed a new ROM and reset my Samsung Galaxy S3 phone many times. Using a network logging app and a "network connections" app shows me the live connections coming from my phone.
My local wireless LAN is 192.168.x.x but I see the IP address change to 10.0.8.1and then reverting back to my local WLAN IP address.
I do not even route that subnet in my network so how am I getting that address? Using network ping apps, I can ping that 10.0.8,1 address from my phone. It's even happening to my other android phone (Gamsung Galaxy Note 3). The S3 is rooted and the Note is not.

Welcome to the Android Enthusiasts! That must not necessarily mean something wrong: your device can have multiple IPs, e.g. one for WiFi, one for your mobile data, and one "local" (in case there's no network available). So a shaky network connection would exactly look as you describe: when the network connection drops, the device reverts to one of its alternative IPs.

is there an open wifi access point or a network you've connected to previously nearby? 192 and 10 are both private IPv4 blocks, so it doesn't make sense that your connection is bouncing between wifi and mobile data connections. mobile data connections normally lease public IPs using IPv6. your situation sounds like the device is bouncing between 2 WLAN connections.
hop into Settings > Wifi > Advanced. make sure that "Avoid poor connections" is enabled. this might help the device ignore the weaker connection. back in the Wifi menu, you can also choose to forget the network that's causing the problem by tapping on the SSID and selecting "Forget."

my phone won't store to my memory card
I have a Sony Xperia M (C1905) and have a SanDisk ultra 16gb memory card but it won't save any of my apps pictures or videos or anything to it is there anyway to fix this?? It keeps telling me I have insufficient space because it's used my internal storage but still have 16gb on my memory card why???

From your comment on the answer I assume you can write to it (and already transfered files) – so what you're really asking about is how to have your apps moved over, is that correct? If not: what error are you receiving?

Try this one - Open Settings > Storage > Transfer data > Check all. This moves all the content especially Photos, Music, Videos from internal memory to SD Memory card.
Some video and audio formats may not support this operation. For moving those use ES File Explorer from Play store.

I've done that but I really want to move apps not just files

Xperia doesn't support this operation even if you root the device. That's a weird limitation by Sony. Developers are still trying on this thing.

Developers in the sense people on XDA Developers website.

incorrect mapping from brightness slider to real system values
Sorry in advance for bad english and also for a noob question.
I have a problem with brightness on my tablet Supra M94BG. There is a system brightness slider, the range is 0% -- 100% (as usual), and the problem is that 0% corresponds 0 value in /sys/devices/platform/leds-mt65xx/leds/lcd-backlight/brightness , and 100% corresponds 90 value, and not 255, as expected. Manual setting of value in /sys/.../brightness to 255 gives really maximum level of brightness (as desired), but this value resets to 90 after screen is locked.
How can I correct the mapping?

Maybe everytime you unlock the screen, the phone sets the brightness to the current brightness value specified (set) by the slider.
This is something that has to be changed in the framework-res.apk .
If you know how to edit it using APKtool, just proceed.
Otherwise, the most easiest way is using a Tasker app.
Just add a task to set (echo) the brightness to 255 everytime screen is unlocked.

Thank you very much for letting me know about Tasker app, it is the best temporary solution for now! However, I think I still need to fix framework-res.apk so for this bug not to appear at all.

And that's not a bug :) It's just to save your battery or avoid heating or something.

As you have told me, I disassembled framework-res.apk and found these values there:
<integer name="config_screenBrightnessSettingMinimum">30</integer>
<integer name="config_screenBrightnessSettingMaximum">255</integer>
<integer name="config_screenBrightnessSettingDefault">102</integer>
No trace of maximum value of 90. Do I have to search in another place?

So, i want to ask yout that, is the wrong message will be deliverd to the person or not?

Most probably yes, single tick means the message is received at server and is awaiting to be delivered to the person you sent it to. (Double tick means the message is delivered, and the blue tick means it's read)
I'm afraid to tell you, the image has been sent, and the person will receive it once he connects to the internet. But as you have deleted the image from your phone you won't get the second tick and the blue tick for that matter, and you'll never know when the person actually saw the image.

hidden photos in gallery lost/deleted/disappeared?
So I have a problem... all my pictures in the galaxy's own 'hide photos' option have deleted. I went on holiday and took some pictures. I decided I would sort them and keep only my holiday photos in the gallery and hide the pictures of me and my friends. After a month of checking back at them couple times during the week they decided to disappear just after I had a look at them. I'm pretty sure I didn't delete them because if I did have accidently  clicked the deleted button it would take a couple of minutes for round about a 1000 pictures to delete and I did not see any box that said deleting 'whatever amount of number out of a 1000' please wait because I looked back at my phone within seconds. I've read many different forums which told me to use third party apps or going through to my files > ticking the show hidden files in the settings > clicking all files > phone/sd card storage > .hide file > island > and my pictures should have appeared..  but they did not... all I got was an empty file. I had no luck with anything so far. Please help me to retrieve these photos, they are important to me. Any help will be appreciated. Thanks

Are you rooted?

Launch app with UI in background
Is it possible to start a regular app – with a GUI – in the background, without displaying its UI? Also, it needs to be launched from the shell terminal, not from java.
What I'm using currently:
am start -n com.nolanlawson.android.simpletalker/.MainActivity -e text "Sample text for TTS."

What is the final objective?

Apps can run services in the background, but activities are for UI; it doesn't really make sense to run an activity without displaying it.  If the app has useful stuff that it can do when it's not in the foreground, it should do it in a service.

It makes sense to me. Consider a TTS app which allows to be launched from console with a parameter for the text it has to speech. I need this app's UI to stay in the background while speaking, and I'm taking the compiled app as-is, without modifying its source. The same should probably be achieved best in Java, rather than console, it seems.

I don't believe you can, however you could try using the StandOut library to achieve your goal. The StandOut library allows you to have floating windows on the screen.

How to filter IP address in a hotspot/tether
For non rooted phone IP can be filtered/blocked by using a firewall like NoRoot firewall. Every apps in the pthone can be controlled this way. But when mobile data is shared with other devices (like tether to a PC, WiFi hotspot) they aren't under the control of the firewall. Applications, like software update, on the other devices are sucking the whole data which lead to exhaustion of mobile data.
So How to filter IP/domain from  connection on a phone that act as a WiFi/USB hotspot.
I have visited many hotspot manager apps but none of them seems to have a filter option. Does any hotspot manager support it? or any method? nonroot highly recommended.
**Update  **
PLAN to identify spam IPs
After creating the hotspot client devices are connected. Clients are requested wait for some time so that spam apps begin to update/download by connecting to their server. These IPs are noted and filtered by the hotspot manager.

I believe your question is this: In your device you can control which app gets to connect to Internet and fetch or send data by using the said firewall app. However, when your phone is tethered the other connected devices consume like hell because the apps on those devices are not controlled by anything, so they all try to get a share of mobile data through hotspot.

But why are you trying to filter the whole IP address? Filtering usually implies restricting something and that would mean access denied to the whole device. Is that what you want? Or the objective is to identify and restrict a particular request from an app running on an other device? In Android 4.2.1 you can block the tethered device's IP address temporarily. Which Android version and device do you have?

ICS. stock ROM. I don't want to block the client. Just some domains from that client like updaes.android.com

That can be achieved through DNS. On rooted device put 0.0.0.0 updaes.android.com in /etc/hosts. On non-rooted devices use some firewall or ads-blocking VPN app that incorporates hosts functionality.

Recover user profile image
Android 5 has options to have users, so multiple people can use the device. I had my Motorola G 2 set up to use multiple users, but it now only has one profile which would be nice to recover the profile picture of:

Can this be done (without root etc as well)? I can get a very low res 90px image from screenshots but that is about it.

/data/system/users/0/photo.png is the picture you're looking for. But, you cannot get that pic or even visit its parent directory without elevated privileges. adb shell isn't enough to get it.
There is a catch here. In my Paranoid ROM (AOSP) I found that the owner is supposed to create a contact (about me) for himself. Any image used in that contact is directly user by the system as the image of the user, and hence, gets copied to that said location. This isn't the case in CM12 though.
The images provided to contacts are saved at the location /data/data/com.android.providers.contacts/files/photos. Your profile image is saved in /data/data/com.android.providers.contacts/files/profile.
Both location are inaccessible by ADB and an ordinary user. Now that I've given you ample stuff to search and research, it is up to you to choose a path: 1) root and get the stuff easily, 2) find an app that can copy the profile or contacts images in a standard format from which you can retrieve your profile image.

You can export the contacts through SMS or Bluetooth. The .vcf file would have encoded image into it. May be you can convert that encoding into a full-fledged image since Android can.

How to repair-unbrick-solve my Galaxy Tab 3 10.1" after rooting
I was trying to root my device, but I think something went wrong. I may have bricked my Galaxy Tab 3 10.1.
When I noticed that the device was in loop, I tried to root with the CF-Auto-Root file a few times with Odin3-v3.07
The tablet doesn't start up. The only way to turn it on is to plug the USB cable in, then it starts and doesn't pass through Loading Screen where it says 'Samsung Galaxy Tab 3' something like that.
And when I connect into my PC, it starts up but keeps itself in a loop.
By loop i mean -> Turn on, Show Galaxy Tab 3, restart and show again...and again...and again...
Now i think i could get him to charge his battery..i hope at least, cause when he was in a loop i think he didn't charge as well as it should...
I try to go Recovery mode, to try to wipe those sys folders that we know can help in this loop scenario, but it just won't start recover mode, i think it did just now, but battery was low so to avoid further problems, he just says battery low or voltage low...something like that...too fast to read...And then he just turn off...
I do have TWRP to recover, i did a sys bkp before, is on my ExtSdCard, but i took it off from the slot for now...When i first saw on web that if not enough free space is available it can get to startup loop, but as i choose my ExtSdCard to save my Sys BKP i don't think that is the problem...Should i put it back in?
Sorry
Can someone give some hint, anything really?
Oh and i downloaded the ZTO version of firmware already to try out later...if i can't get it to at least work for boot...if...just if...
But i saw here that some have been able to unbrick so i'll die trying :D
I hope not literally..haha
Firmware that I downloaded is
ZTO-P5200UBUAMF6-20130801180132.zip ~1.1Gb
There are a few different types of bricked devices: hard brick, soft brick or coma brick. Which one applies to my situation?

I live in Brazil, so English is not my native language, sorry for any mistakes I might have made.

If you have access to a custom recovery, just flash any ROM for Galaxy Tab 3 10.1
If your phone doesn't even boot, try flashing the stock image using ODIN.
This might help: [HOW-TO] Unbrick Galaxy Tab 3 10.1

Ok, but in oder to do that, shouldn't  be on download mode?
apparently i can't set DownloadMode, so how can i do that...not even recovery mode....
Let's way for full charge of the battery and a'll try that...
Also, when i plug it on my PC, he just start up already by him self, i hear the  win sound when connects something on usb, and them imidiatly  the other sound, when is disconnected

It looks like you bricked your phone. Fortunately Samsung devices are generally easy to recover from a Brick.

"I do have TWRP to recover  i did a sys bkp before, is on my
  ExtSdCard, but i took it off from the slot for now"

Good thinking. Insert that External SD card and perform a recovery from that.
A website that is essential for anyone rooting their phones is xda developers. There is a thread dedicated to what to do to recover from a bricked device [HOW-TO] Unbrick Galaxy Tab 3 10.1 by Zachisimo.
This will take you step by step on how to recover to stock android. Once you recovered, you can always root again and install a custom rom (if you want to)

How do I enable AWS band on Galaxy S4 GT-I9515L?
My phone broke while I was in Brazil, so I picked up a Samsung Galaxy S4 GT-I9515 (I9515L for Latin America). When I got back to Canada, I realized that it didn't have the AWS band (1700/2100) enabled, so I couldn't use it with Wind Mobile. Wind Mobile in Canada uses roughly the same bands as T-Mobile in US.
When I search for networks, I only see "Wind Away". On my other phone, I see "Wind Home" as I expect.
From my reading, GT-I9515 is supposed to have the same hardware as GT-I9505 except for the touch screen driver. I can find other GT-I9515L phones for sale on Amazon with the AWS band enabled.
Details:
Model number: GT-I9515L
Android version: 4.4.2
Baseband: I9515LUBU1ANJ1
AP: I9515LUBU1ANJ1
CP: I9515LUBU1ANJ1
CSC: I9515LZTO1ANJ1
Kernel version: 3.4.0-2953991 dpi@SWDD5101 #1
Build number: KOT49HI9515LUBU1ANJ1

Idea 1: Reconfigure Qualcomm modem using QPST and QNC backup
Enable AWS on Samsung Galaxy IV AT&T i337 & Canadian i337M says that AWS can be enabled on other Galaxy S4 models (not I9515) by using the QPST utility to restore a QNC configuration.
I successfully installed Samsung Kies, the phone drivers, and QPST. Taking a QNC backup worked, but restoring the supplied QNC file did not work.
It failed at 5% with "Received an invalid command from the phone" error. The phone continued to function otherwise, but the AWS band did not become available.
Is there a known good QNC configuration for GT-I9515L?
Idea 2: Reconfigure bands in NV_RF_BC_CONFIG_I
Enable AWS for i337 newer roms (nj4) 4.4.4 says that AWS can be enabled by flipping bits in line 1877 (NV_RF_BC_CONFIG_I).
It requires root, and I was able to successfully root the phone by following [GT-I9505 + GT-I9505G] CF-Auto-Root and applying the CF-Auto-Root-jflte-jfltexx-gti9505.zip file for the GT-I9505 model.
Initial values on the phone:
441 NV_BAND_PREF_I      65535
1877 NV_RF_BC_CONFIG_I 562950035735424

I used the mzTool utility mentioned in Unlock all bands of your Qualcomm device to generate the following values and apply them using RF NV Item Manager utility.
441 NV_BAND_PREF_I      896
1877 NV_RF_BC_CONFIG_I 1688849976132480

After applying the values, I used Terminal Emulator on the phone to run these two commands:
su
setprop persist.usb.eng 0

After rebooting the phone, I continued to see my new values in RF NV Item Manager, but the phone still didn't see the "Wind Home" network on the AWS band.
Do I need to do anything else or change any other fields to enable the AWS band through this method?
Idea 3: Install new baseband/hybrid modem on the phone
The answer to Frequency band modifications for Samsung Galaxy S4 says that I can enable the AWS band by flashing a new baseband or hybrid modem onto the phone.
I tried flashing a few hybrid modems using Odin3, but all of them failed to flash. The error was a Fail! (AUTH) message in Odin3.
Is there a known good hybrid modem for this phone that works with the AWS band?
Idea 4: Install a new firmware
I tried flashing the United Kingdom firmware for GT-I9515, but it didn't work.
There are some firmwares for GT-I9515L, but none specific to United States or Canada. Flashing the phone with the Trinidad and Tobago firmware updated the phone to Android 5.0.1, but still doesn't show the "Wind Home" network on the AWS band.
The baseband is now I9515LUBU1BOF1, but I'm happy to revert to the original Brazil firmware if required.
How can I successfully enable the AWS band on Galaxy S4 GT-I9515L?
Idea 5: ServiceMode
Based on Loreno's comment, How To Unlock Samsung Galaxy S4, and How To Make Your Android Perform Dog Tricks, I did the following:

Enter *#0011# in the dialer to automatically open ServiceMode
In ServiceMode, Menu > "Back"
Menu > Key Input > Q0
Wait a couple seconds. If nothing comes up, do Menu Back and Menu Key Input again.
With luck, the following menu is now displayed:
MAIN MENU
[1] UMTS
[2] CDMA
[3] LTE
[4] SIM - Not Used
[5] DOCOMO DEBUG SCREEN
[6] run EFS SYNC()
[7] DEBUG SCREEN

Choose 1 UMTS
Choose 1 DEBUG SCREEN
Choose 6 PHONE CONTROL
Choose the Network option that's not LOCK
Choose the GSM menu
At this point I see this menu at GSM bands. AWS (1700) is not on it:
[1] GSM 850
[2] GSM 900
[3] GSM 1800
[4] GSM 1900
[5] GSM 850/1900
[6] GSM 900/1800
[7] GSM ALL

1700/AWS also doesn't show up under WCDMA or LTE.
Is there a way to make 1700 or AWS show up in the ServiceMode menu?

Try to change it in the service menu. Open the dialer, enter *#27663368378#. Then UMTS, Debug, Phone, Network, Band, AWS.

@LorenoHeer Good idea. Unfortunately, the 1700/AWS band doesn't show up for me in the ServiceMode menus. I've added details to the question.

Idea 1: Reconfigure Qualcomm modem using QPST and QNC backup
I was able to do this method, but LTE B4 (1700/2100 AWS still does not appear)
I downgraded to 4.2.2 to complete the 337_AWS restoration
Pude hacer este método, pero LTE B4 (1700/2100 AWS sigue sin aparecer)
hice un downgrade a 4.2.2 para completar la restauracion de 337_AWS
saludos desde argentina

I'm glad it worked for you

not worked for me.. just made the metod one, but LTE B4 (1700/2100 AWS still does not appear)

"Received an invalid command from the phone ..... REMOVE IMEI FROM QCN AND THEN FLASH IT WILL SOLVE THE ISSUE."
Since I haven't learned how to edit a QCN file yet, as an experiment, I used the QPST to back up and create an XQCN file.  When I tried to restore this file, I got the same error!  If IMEI conflict is the issue, why would my phone reject an XQCN file from itself, ie. same IMEI number?

"Received an invalid command from the phone"is anyone find the solution?
REMOVE IMEI FROM QCN AND THEN FLASH IT WILL SOLVE THE ISSUE.

Taking pictures with headphone jack
It's a first generation Moto G running Android 5.0.2 and I'm trying to make this headphone-jack selfie stick work.
Tried with both Motorola Camera and Google Camera apps. Both take photos correctly when the volume button is pressed on the phone. Neither take a photo when the button on the selfie stick is pressed. I would consider the product defective, but Google Camera actually focuses when the button is pressed.
Is there any setting I'm missing, or a way to find what the selfie stick button is actually doing so I can re-map the action?

Check your volume sliders, it sounds [see what i did there? xD ] like
it's your notification volume that triggers the mechanism. At least that what i got when you said pushing on the volume button did the trick.
Unlock/unlink your volume sliders if they're locked/linked, also if your rom has safe earphone volume feature, disable it.

Can a app store data beyond uninstallation?
I've an app that creates an account for me but uses no login credentials (starting the app logs me into the account).

When I uninstall and reinstall the app it still logs mit into my account.
When I reset my Android Phone (e.g. new OS) it does not remember my account

My question is: What possibilities could this app have to do such behaviour and how do I eradicate it completely from my phone when uninstalling it?

A lot of apps leave behind what I like to call junk files.
There's an app called SD Maid which helps you clean up your F.S. (filesystem). There is also Ccleaner and System app remover, these apps will assist you in cleaning up cache and removing apps. You can also navigate to /sdcard/Android/data/ and remove any left over folders an app may have left behind.
What I like to do is clear the apps cache and then uninstall the app. I hope this helps.

Apps can/do store "persistent" data in /sdcard/Android/data, /sdcard/Android/obb and sometimes a mirror of that on /storage/extSdCard,
and some apps tend to leave "corpses" in /data/data. a cache/dalvik cache wipe does not clear this. I definitely recommend SD Maid if you have a rooted device. I've been using it for centuries. It has functions available even in the free version to clean up corpses and optimize .db files. My take from paranoid land is, if it's still alive , then it's probably doing something.

Google play store now forcing adware on my android
I was being swamped by google play store adware, redirecting my phone to the google play store and various downloads.  It happened any time I activated anything on my phone...  opened a folder.. redirected to google play store.  Recieved a phone call; sometimes I could not clear all the redirects to different apps, usually games or phone tools, until the caller hung up.   Open messages, get redirected, etc.  Cleared the cache and everthing, and it was all good until I accepted the terms and conditions for the google play store, then they were all back.
BAD ANDROID!!
How can I continue to use the Google play store, yet not be harassed all the time to download and install this and that app? It's so difficult to clear the layers of google play store offers that its actually acting like malware.
Please help.
Ren421

Play Store doesn't do that! Your phone must be having a malware  doing all of this stuff. Could you tell us where you're directed to in Play Store? Is it the front page of Store or a particular app? Do give us the list of all the third party apps you've? Also, if you're convinced that it is an adware then consider using an ad blocker.

It seems that you have some kind of malware on your phone. Google Play doesn't acts like this.
You should try a factory reset and see if this solves your problem.
By the way, this will ERASE ALL YOUR DATA like photos, sms...and apps data so you'll have to log in again on every app.
Hope it helps!

Rooted phone missing key features, help!
I have a new MetroPCS Lg Leon running lollypop 5.02. I rooted it with kingroot apk (bad idea) and I cannot get the menu bar or swipe gestures to work. I.e. swipe to search,  there is no pull down menu.
I must have messed with some settings in root but I factory reset the phone multiple times and hot reset it if that is any different with the battery out. Not corrected.
The lg startup screen starts each time I boot it as well.  Any suggestions?

Finally found an answer. I had to give the android system full root privledges and/or unroot. It updated as it should to a new version of lollypop in a few days time. Any better answer please post.

how to fix "settings has stopped" error
I was  uninstalling  some bloatware on my lg l15g and now can't access my settings.  Get an error message of settings has stopped. What is responsible for this?

Hard to pin down. Log the action using [tag:logcat] and give us the output.

What are bloatware's you uninstalled? Name them?
As @Firelord asked you, give us some clues, logcat traces will be good.

On my LG L16C (Kitkat 4.4.2) I had that issue several times. I bought the phone only two months ago and realized that certain aftermarket apps were causing the problem-each time my settings froze, removal of newly added apps (one at a time, testing after each) stopped the problem...just added similar apps instead.

Can my Android phone detect when it is in the shade?
Is there any way I can get my Android phone to tell me when I am in the shade? These days the sun is pretty damaging for my skin and was curious about how I could measure this.
Maybe if I put it in a transparent pocket somehow?

Yes, You can do this with your phones' Light sensor(usually located above the screen). It measures the light falls on your phone.
There are some apps in the play store which  provide data about the light falls on you phone and you can  save it.
Such an app is Lux meter.And there are plenty of apps to do this. Search for similar apps in Play store.

I forgot the Google account name that I used for buying apps on Google Play, can I recover it somehow?
I am not sure if this fits here, but I saw a couple of other account related questions, so I'm giving it a shot.
I just resetted my phone and forgot to take note of one of the two Google accounts I had on it, which I was using to buy apps on Google Play and to save some contacts.
The account is not linked to a recovery email, nor is associated with a telephone number. I fully remember the password but only a good part of the username. I never used the account to email anyone at all, not even my other Google mail account.
Do I have any chances to recover the account username given that the account also has a Google Plus profile, and that nobody else except me could be able to tell exactly the Google Plus profile associated with that Google account name for which I remember a substantial part (the G+ account has been configured to not pubblicly show email) ?
I also thought I could contact a developer for an app I bought, and see if they have access to the emails from which they receive a purchase. But I have been told that as a developer you can search order details only starting from the email itself...
Any other ideas? What else could I do? If I don't fix this, I will loose all the apps which I've bought on Google Play and all the contacts saved on that account... :\
I hope there's a a way. Thanks!

In my opinion you should search for devices that you might had linked that account and check if someone has that email address. Think if you ever sent a email using that account to a close friend, family member or other internet service.
You can also take a look at this forum answer: https://productforums.google.com/forum/#!msg/gmail/ydNElvUjJVU/hNjOMBN0dNYJ

Thanks! Actually, no other devices had been attached to that account but the forum link helped me find the account! Reading the post, I gained back some hope in doing what I had already attempted, that is, searching in the sd-card for any hints for the email name. This time I did a more in deep search for "mail" in all files content, and it finally popped out! I got my mail back! Welcome to StackExchange and Android Enthusiasts!

Can I, simultaneously, run two instances of the Facebook app?
Can I, simultaneously, run two instances of the same Facebook app
(which is installed once in the system)?
I want to be active on two accounts (I also have iOS and Windows Phone devices if their support for multiple instances of an app is better than Android's. But my Android phone is my main phone, hence I prefer an Android solution.)
Also, can I get parallel notifications from both accounts (I don't need any chat messages, just the notifications from a specific Facebook group on my second account).

You can change the source code to fool the system that an instance of the app is not present by changing the package name. Method here

Possible duplicate of How can I run multiple copies of the same app?

@RahulParashar I don't think this is quite a duplicate, because if there is some technique that's specific to Facebook, it couldn't be posted on the other question.

@DanHulme So, now, there is a technique, specific to facebook?

@RahulParashar For example, the top answer, which recommends a Facebook-specific app.

Based on the answers, this question seems ridiculous.

You cannot run two instances of app with same package name because when you try to install it out of the box because the package installer checks if an instance of the package you are trying to install is already present and if present asks if you want to update the existing app.
You can however change the source code of an existing app to fool the system that it is some other app with a different package name  by cloning the source code and have a different package name. Reference link here

Also there's another way by making use of the special Facebook lite app.
 Facebook has provided a Lite app which is supposed to work for low-data-speed devices consuming less memory.
You can install one Facebook native app and another Facebook lite app and use multiple accounts. So you'll be able to get notifications from both the apps.
NOTE: This is possible because Facebook-app and Facebook-lite are two different apps (with two different package names com.facebook.katana and com.facebook.lite respectively)

Thanks, it wasn't exactly the answer I was looking for - I was more looking for something along the lines on how to launch an app twice (like you can do from CLI on a Mac) - but it solves my problem so that is good enough!

Hmm, when I try to install Facebook Lite it tells me that "This item cannot be installed in your device's country" (I'm in Europe). Any workaround for that?

@user23122 Download from http://www.apkmirror.com and install the APK. Enable unknown sources if necessary, you can disable it later.

@user23122 you cannot just launch an app from terminal in android although it is based on linux, it restricts users to launch an app in terminal to compulsorily have a particular Activity Name

to do that, goto terminal and type the "am" command with the syntax shown $ am start -n com.package.name/com.package.name.ActivityName

Reference link broken, and now goes to a questionable site.

You can use two Facebook account in a single Facebook application. For that you have to install first an application Parallel Space
that is easy available from Google Play.
There you will get an option for Facebook application, and that Facebook will work in Parallel Space application.

App is running even though disabled! Why?
I did:
pm disable com.android.systemui

I get:
pm list packages -d
package:com.android.systemui

So it is disabled. Still I get:
ps | grep systemui
u0_a71    2053  1183  462960 27552 ffffffff 40089a40 S com.android.systemui

so it is still running, even if I kill it, it restarts! How can it both be running and be disabled at the same time?

It's a bad idea to disable SystemUI.

Why? What can happen except the loss of navigation bar etc?

Pretty much that. I found your comment on the related SO question.

never ever disable system UI strange things may happen as it is required by the entire system so that you can interact with your device as @Gokul NC said

SystemUI.apk is an System app which needs to be always running to provide the Android UI as you know, like Navigation bar, Status Bar, even Wallpapers, and lots more ....
It's a very bad idea disabling it. Even if you disable it, it'll just restart.
If you remove it, your phone won't be having an UI.

How can it both be running and be disabled at the same time?

As far as the question is concerned, I think the current instance of the app will be running eventhough you disable waiting for the effect to take place on reboot.
But Android may not allow SystemUI being disabled during boot, by forcibly starting the app and its services.
If you are a developer/debugger and really want to disable it for some reason, this might help: https://stackoverflow.com/questions/28055413/can-i-disable-systemui-from-within-my-android-app
I think you can also Freeze it using apps like Link2SD :)

A few apps like these are necessary to run the OS. So, no matter how hard you try, this will start again and again. In fact, this default setting is just to prevent your device from getting bricked or behaving abnormally.

my sd card suddenly crashed
In a morning time i was seeing pictures in my phone.
After 2 hour i saw my phone ( Samsung galaxy y ) it was
show memory card unavailable.
I did reinsert memory card many time in my phone and also in computer. But it can not find that..
i have captured many pictures at vocation time it was very important for me.
Please help me  can i recover my pictures ? please please help me. what i do ?

That sounds like your card is just dying (or already has died). If I read your question correctly, you can mount and read the card just fine – but some files are disappeared? If so: are all newer files gone? // It could also be you've (accidentally) deleted those files. In that case, please check our data-recovery tag-wiki for first aid, and especially check How to Restore Deleted / Formatted Files on HD Micro SD Card.

Also see: How to recover data from a damaged SD card?

Try cleaning it, if it's broken not much you can do except trying again. If it's really really important you can send it to experts maybe they can recover something !

I doubt that helps. If it would be that, the entire card would be unreadable; there's nothing you can "clean" to show a specific file – either contacts are really dirty (then the card doesn't mount), or the card mounts fine (then there's nothing to clean).

So it's recognized ! Try recueva a nice program to recover files

Micro SD cards have a nasty habit of crashing at the most annoying times. There is not much you can do if your sd card has truly died other then buy a new one and hope your files were backed up. Sometimes you can recover a card if it's simply corrupt but if your cards controller goes pumpkin witch they do tend to do a lot these days your sol.

How can I backup and restore Cyanogenmod 12.1 rom installed on my Samsung Galaxy 2 i9100?
Cyanogenmod(12.1)'s recovery has no backup or restore option. As I read in the answer of a previous post, CyanogenMod recovery is basic, so we should flash another recovery. The easiest way would be to use rashr, Fashify or GooManager to install CWM or TWRP. Unfortunately, these solutions don't work on my i9100.
An other answer in the same post says : "Especially for Galaxy S2. I stuck with Cyanogen Recovery for a couple of days. Neither Rashr nor Flashify worked for me. In the end, reflashing a TWRP kernel (Apollo 9 light) with Flash Gordon did the trick."
My questions are where do I find this TWRP kernel and how do I install it ?

I found a link to a signed stock kernel providing TWRP v2.8.7.0 on xda Forum : [ROM][I9100][5.1.1][OFFICIAL] CyanogenMod 12.1 Nightly Builds
It can be flashed with the Cynogen Recovery.

Why are the app labels missing in "all apps" list?
My "all apps" list doesn't show the app names and I have no idea how I turned it off. Because I'm using a theme I have a really hard time figuring out what icons belong to which apps.

How do I turn the labels/names back on for the apps in the "all apps" list?

Welcome to the Android Enthusiasts! It might help if you [edit] your question and include device name, Android version, and the launcher used – without that it's hard to tell for us as well.

@Ariella Which launcher and theme are you using?

1 - In your homescreen, press and hold on a free space to get to this menu

2 - Click on the up arrow to enter advanced settings and you'll be presented with a screen like this

3 - Scroll down till you get to Drawer Settings(Do not confuse it with Homescreen Settings).   In the Icon Labels options change it to Show

Thanks for the detailed answer (with pictures!) On how to solve my problem.

I'd wager that you're using Cyanogenmod or CyanogenOS with a custom theme. The fourth icon in first row belongs to AudioFX, quite common in Cyanogenmod.
If that's the case then go to home screen, press Menu button. You would see options such as Wallpapers, Widgets and more. Swipe up that dialog and change Icon labels under Drawer Settings from Hide to Show.
That should take care of the issue.

That was it. I'm still new to android so I wasn't even aware this was a launcher setting? I got this with my phone so I never installed it myself. I thought it was a phone setting, hence the lack of information with my post. Thanks a bunch!

D3 barchart on Firefox Android 4.4.2
It seems I that I can't load this d3 barchart on an android phone (android version 4.4.2) and on Firefox browser. Firefox on Android has javascript enabled (checked from about:config) and also the built in android browser and Chrome also is able to load the same page and show the visual. So it has to do something with Firefox. Any ideas what to check?
Attached is a screenshot of the d3 barchart page loaded in Firefox for Android

Screenshot - Click to enlarge image

I have no problems loading the page in Chrome and Opera and UC Browser. Did you change anything in the about:config? Could you post us the screenshot on how the page is displayed in your Firefox Android browser?

@Lucky : how can I post a screenshot in this comment? No haven't changed anything in about : config.

you can click [edit] link on your question anytime you want to post and update or add additional information. Look at How to upload an image to a post

@Lucky : Thank you. I was trying to post the image on the comment, whereas it should go on the original post... So I do not know why I am getting this. Are you able to load the link on a Firefox in Android?

Unfortunately, I don't have Firefox browser on my android. Could your reset the browser cache/settings and check? Also please visit this url to find if javascript enabled

@Lucky : History and cache erased. Firefox started with a Welcome to Firefox! prompt, as if it was newly installed. Javascript is enabled. D3 bar chart page in question visited but still visual does not show, leaving me with the same attached screenshot in the post question.

Have you checked the Request Desktop Site under Menu and tried loading the page?

@Lucky : Checked Request Desktop Site for Firefox on Android but still visual on page does not show. Uninstalled and reinstalled firefox and when started for the first time also checked Request Desktop Site but problem persists. Unchecked also `Request Desktop Site', with the newly installed Firefox and again no luck...

As Firelord mentioned he has not problems loading the page in his Firefox broswer. Are you sure you are using the updated version? or Are you using the Firefox beta?Please mention your version and are you using any other mobile-addons? If yes please uninstall the mobile addons and check.

There is no problem in Firefox. I have tested the said website on Firefox v35.0.2 and v40.0. It shows the graph as good as it does on Desktop.

If you are running the latest release yet facing that issue then it implies that your Firefox's configuration is messed up. I've NoScript addon installed and I allowed cloudflare.com and ocks.org in it, since both are needed to show that chart.
I suggest you open Guest mode in the browser and visit that site. It should definitely help in understanding whether it's Firefox itself or your custom configuration that's causing the issue.

Vodaphone 875 Uninstall SuperSu
I own a Vodaphone 875 model phone, which I rooted previously using Cydia Impactor. Installed SuperSU, everything was fine and dandy, and when I needed to transfer it to another person who wasn't comfortable with a rooted device, I used the standard master reset button within the Settings page. However, on startup, I discovered that SuperSU was still installed, and, knowing that it was now a system application for whatever reason, I attempted to reroot with Cydia Impactor again. However, something changed, I have no clue what (probably a Google update or the like), and the exploit no longer works for my phone. A quick google search resulted with people having this problem, on different devices, with the solutions being a flashable zip, which I have no intention of doing.
Therefore, my questions are as follows:
How do I remove SuperSU from my device, permanently?
Is there a flashable zip for my device?
Any help would be extremely helpful, as I have been looking for a solution for over two months now.

SuperSU gives the option under its settings to fully unroot the device. It usually works well. Have you tried it?

The only problem being that, when the phone was reset, it clears the su instructions, making the removal of a system app impossible.
