Where do I find Recent Apps?
I am trying to map my Recent Apps to a gesture, instead of home button long-press.  However, I can't seem to find the location of the Recent Apps function.  Before Lollipop I think I found in Activities > Settings; now I don't see it anywhere there.  Anyone know perchance where Recent Apps is located?
I'm using Android 5.0.1 on a Samsung Galaxy s4.

Which launcher are you using? I think this may be launcher dependent, but I can't be sure

Also, what's your device model and Android version? There's never such setting on vanilla Android (Nexus 4~5, KitKat~Marshmallow).

@1990clb The launcher is Lightning Launcher.  I used to use Nova for a while, I think both Nova and LL used to have Recent Apps in the same place, in the Activities > Settings section.

@AndrewT. It's a Samsung Galaxy s4.  The Android version is 5.0.1 (Lollipop).

Nexus 7 - Stuck in recovery mode
So I bought a nexus 7 a while ago and after a while I jailbroke the nexus 7 and installed cyanogenMod. I'll be very honest I followed a tutorial online and it worked. After a while I was stupid enough to install an unstable version. Which caused my nexus to basically break ( when I say break I mean I couldnt get past the recovery mode screen).
Currently I am stuck in recovery mode. I turned my nexus on today after years.
And I see this ( I apologise for the bad quality of the image )
I have no idea where to go from here. How Do I fix this? Whats the next step.
I honestly have no clue at all.
Any help will be greatly appreciated.

My advice would be use a Nexus toolkit to restore your device back to stock. It's often the easiest way. And in future make sure you make a backup in recovery before installing experimental builds

@1990clb Thank you. Would you happen to have any tutorials that I can follow to get it back to stock? Also I have a macbook air, any idea where I'll still be able to download and work with nexus toolkit?

Screen shot in power menu
On a previous phone, the HTC One X,  I had the print screen option show up in the power menu. It was along side shut down,  restart,  etc..
I now have the Vodafone Smart 6 Ultra but I can't find any settings relating to the feature I want.
Is it possible to add the screenshot menu option without rooting my device?

Similar but unanswered question: Can I change or add to the power off menu in Android 5.1?

Does this help http://www.techmuzz.com/how-to/android/add-screenshot-option-in-the-power-menu-in-lollipop/

App folders on homescreen being removed automatically when a new app is installed
I have HTC Desire 820 running on Android 5.0.1 Lollipop. I have folders with favorite apps on the home screen. But whenever a new app is installed, all those folders disappeared, and the home screen was being set to default.
I cannot rectify this issue and even cannot find out why this is happening. What is the possible cause and how to fix it?

Are you using Nova launcher? If yes, there is an option in launcher settings to disable this and also to lock the home screen from making changes to it

Not sure what this nova launcher is, is that an app to lock the app bundles??

Nova launcher allows you to customise your UI in different ways and allows you to mask your stock UI.  It had many other features which make it attractive for those who wish to alter UI

Hmm but I think it is not my issue, all my app bundles are being removed when a new app is installed.

Which launcher app are you using? If you don't know what does that mean, then we will assume that you're using stock launcher. By app bundles, are you referring to folders?

Yes its just folders created when we club any two apps

App sending spam messages to my contacts
My phone sent the following message to all of my contacts:

Install this voice messenger just to talk http://mrv.withmechat.us/Cun

I know I didn't send this message and not to mention it sent it to all of my contacts at exactly 9:41AM. Is there a logger that can help me find what app or process sent that message?

Following the link leads to this app: imo free video calls and chat. You sure you didn't install this app? Otherwise, please refer to any questions related to checking app permission.

You could find the default text messaging app in the settings

I just ran into this same problem today. It was sent by the Imo app itself. Don't use or install this app!
I recommend leaving a bad review on the Play Store and reporting the app on the Play Store.
To find out which app sent the spam, you can use Android App Ops if it works on your phone.

I would also suggest you go to settings -> Apps -> Click on the app -> Then uninstall. You could also just disable all permissions for the app if you wanted to keep it installed for some reason.

Delayed Wake Up Time
I'm having issues with my LG G3 CM13. Whenever it's locked and I double tap the screen or press the button on the back, it takes about 5 seconds for it to wake up. Could anyone help me with this issue?

are you using a custom launcher? do you have any other applications running that may hog resources?

I'm using the default trebuchet that comes with cm13. When my phone has been locked for a while, it unlocks instantly. But when I lock it and then go to unlock it, it takes forever

Are you using stock CM13 kernel or something else? Since there is no stable  CM13 yet, your issue may be resolved in another nightly build if you report it to CM. Try it.

Cannot use ADB on a bricked phone
I'm trying to unbrick a soft-bricked Android phone, and many tutorials say to use ADB to fix it, but I cannot use ADB or fastboot, since the device is not reconized. It's a Lenovo Zuk Z1, I am running Lubuntu, and it bricked because i formatted every single partition with CWM recovery, I can go into Zuk Recovery and download mode.

Welcome to the Android Enthusiasts! If you really wiped every single partition, your device has no OS anymore – you will need to flash a ROM. See: Where can I find stock or custom ROMs for my Android device?

I have already tried to flash a new ROM with fastboot and heimdall. That is my exact problem, I can't do anything on it now.

I don't know that device; but can't you flash a ROM from within CWM?

I suppose I can, but i cannot go into CWM anymore.

Argh. So you wiped /recovery as well? Uh-oh. Sorry, in that case I'm out. That doesn't leave many choices (if any at all except for JTAG). Guess you've successfully created a paperweight :( You could try customer care and ask whether there's the possibility to boot from an SD card (that way I was able to resurrect a tablet in a comparable situation); apart from that, no more ideas here, sorry.

There is no SD slot on this phone. Don't worry, thanks for your help!

Anytime. I'd still ask them – maybe they've got a work-around booting via OTG (though I'm not sure whether that's even possible on Android devices). Good luck!

Some apps won't open anymore
I've got a problem on an LG G4 with android 5.0 : Some apps can't be openned anymore. Facebook and and supercell games like 'clash of clans' for instance.
Facebook close each time I try to open it and supercell games are locked on a black screen. That's why I didn't think it was the same issue but both happenned at the same time twice ... it has to be something they have in common...
It happenned a first time and the only way I could unlock it was to factory reset the phone.
It worked then for a few days but here I am with the same problem again and I'm looking for a way to fix this without factory reset each time ...
I don't have any clue... maybe someone here can help ?
Edit :
I tried to uninstall facebook, reboot, reinstall.   still crash at startup :(

Android's logs might give you a clue. Please check, then [edit] your post with your findings. Good luck!

I've found out that it occurs only when developpers options are enabled :/
As a developper, I need to enable those sometimes and the problem appear again.
So now I just disable them when I don't need it and it solve the issue.
If anyone can explain it I would be interrested.
Thx anyway

how to fix bricked ascend P6 with new firmware
I have a Huawei P6 ascend that currently will not boot to android. The splash screen will come up and the huawei red rose stays pulsating forever - this is apparently after huawei forced an unwanted software upgrade (since I didn't initiate any upgrade).
When I hold vol +- and reboot I get to the 'bios' or rom update mode (whatever the real name of this mode might be).  So reading some forum entries I put a file 'update.app' from here on a sdcard (both zipped, and unzipped in a folder 'dload' as well as at the root of the sdcard.)
Upon booting into rom-update mode however I never seem to get a successful reflash.
The system says:
ro.build.version =4.42
ro.product.name=UEDGE
Current build version release is not 4.2, don't need move/
Warning:battery percent is less than 15
Huawei USB update fail....

fooling with various options that I get to after a while (like wipe data etc) doesn't seem to help so far.  Any clues?
I am now also trying (again) the options

Hide buttons overlay (e.g. 5 second burst) on Google Camera
I have been getting overlays as such on my Nexus 5, Nexus 6 and now my Nexus 6P - haven't noticed exactly when they start to appear and have yet to find a way to disable them - please take a look at the following image:

Screenshot (click to enlarge)
If you look at the upper right, you should notice a few buttons on the viewfinder. It used to be just two, now I have three after the camera app updated. They were not there when I initially got any of my Nexus devices but shortly presented themselves afterwards.
I do use my Nexus devices for debugging so I have disabled debug mode to see if there was any connection, but this does not seem to be the case.
Is there sort sort of hidden button I must press (ex; how the developer menu is activated) in order to hide these buttons once again?

The buttons in the upper-right corner seem to be the flash indicator, HDR mode, and self-timer.  To what buttons are you referring?

I recently had the same issue with my 6P, running 6.0.1 and the latest Google Camera version 3.1.021. It turned out to be a result of having the Screenwise Trends Panel app installed on all my phones. Enabling it in Accessibility Services causes the buttons to show up. From my searching there is no real solution other than to disable the Accessibility Service toggle for Screenwise. Then the buttons go away.

AH! Wow, seriously! Yep, I make use of Screenwise as well for some cheap Google Play funds - guess I can uninstall it on my main device at least.

The buttons overlay (i.e. Z-, Z+, and 5 SECOND BURST) are part of Android's accessibility feature, TalkBack. Refer to Google Camera Help - Use TalkBack with Google Camera.
To hide the buttons, you need to turn off TalkBack feature on Android Settings - Accessibility - TalkBack - tap to toggle off.
Note: the buttons are integrated to the TalkBack feature, so there's no way to hide the buttons without turning TalkBack feature.

This is neat, but TalkBack is off on my device.
Turning it on then back off, does not get rid of the buttons either.

@avluis I see... this is the only clue I have tested and proven on my device, but it seems there's something more in your case... I'll try to experiment with it again, but I can't promise the fix... Edit: try to switch off any Accessibility option and see if it helps. Just now when I tested Switch Access accessibility, the buttons also appeared.

I too had this menu enabled today. Later I found that, I was playing around with accessibility settings today. I've (accidentally) enabled "Switch access", so I got this menu in camera app.
Now after disabling the Switch access, this menu was gone in camera.

Nexus 6P remote control headphones not working
I recently acquired a Nexus 6P, which runs Android Marshmallow. I'm trying to use it with my Beyerdynamic Custom One Pro Plus, which has a mic with a remote control (one button, wired, not Bluetooth, which I used to use for starting and pausing songs, and answering phone calls on my previous device). I figured it would work on my Nexus 6P as well. However, I've found something very peculiar. I have three scenario's:
Scenario 1
I simply plug in my headphones, click the button to start music. I do not even unlock my phone for this, nor do I start Google Play. This used to work on my previous device.
In this scenario, the button does not work. Nothing happens at all.
Scenario 2

I plug in my headphones
I unlock the device, start Google Play, and start a song (not using headphone remote).
I then push the remote button on my headphones to pause the song.

In this scenario, the button does not work. Nothing happens at all.
Scenario 3 (this is where it gets interesting)

I plug in my headphones
I unlock the device, start Google Play, and start a song (not using headphone remote).
I lock my phone, while I keep the music playing.
Then, while the music's still playing, I unplug my headphone from the device (when I do that, the music automatically stops playing).
Then, while I keep the device locked, I plug in my headphones again.
I then try the remote button.

When I do it like this, it works perfectly! I can pause and start the song, and when a call comes in, the music is faded out, my ringtone sounds, and I can answer and end the call with the remote button, without ever unlocking my phone. In other words, it works exactly as I expect it to work.
I have tested this over and over again, and every time I get the same results. The remote button only works in scenario 3. This erases my suspicion that it could be a hardware problem; after all, if it were a hardware problem, the remote wouldn't work in any scenario, right?
So my question is, does anyone have an explanation/solution for this? Because it's very cumbersome to have to go through all the steps I described in scenario 3.

did you resolve this matter? I'm encountering the same behavior

Hi @EugeneKrapivin this matter is not resolved yet. I have, however, found this thread on the Google product forums: https://productforums.google.com/forum/#!topic/nexus/9KN9pS3bsgU;context-place=topicsearchin/nexus/category$3Anexus-6p
I have phoned my headphone manufacturer to see if the wiring standard is CTIA or OMTP. It was CTIA, which means that in theory, my headphone remote should work. But it doesn't.
I think it has something to do with the signal thresholds that are defined in the Nexus 6P's software for interpreting the remote's signals. But I'm defintely no expert on this.

I think that once the remote works it should indicate that the signaling is OK, otherwise it wouldn't work. I think there is a a SW problem in the detection of the remote and starting up a process that interprets the signals from it.

I have custom rom installed but I have a problem
i installed a custom rom. now I want to open recovery but when I open it says "do you want to start factory reset (it will delete everything in phone)"
I don't want everything to be deleted I just want to start recovery. what can i do?

Is it an LG? And by custom ROM do you mean custom recovery?

Yes LG G2. And no I mean rom. Cloudy G2.

Ok. I figured since I also own LG. (Also Cloudy ROM too, but that is irrelevant in this case) You can go on to say yes and it'll boot into recovery.

are you sure? it says it will delete everything.

Yes I'm sure. You can ignore it completely. You used the Power + Vol Down combination when booting up I assume?

yes. i am normally familiar with recovery. but this phone is new and it is the first time I see this warning.

I will post a detailed answer.

it worked. i was actually scared to be honest. thank you. accepted answer :)

Firstly, let me say this: You can ignore it and go on since it will not actually delete anything (assuming you actually got a custom recovery installed)
The combination of Power + Volume Down when LG logo appears during boot will bring the screen you mention. It gives you this warning because that is what the stock recovery is meant to do. However, with custom recovery being installed, it will just boot into recovery mode. This is because the process of factory resetting is done by recovery of the phone.
For example, if you start factory reset on Settings, it will just pass your command to recovery, and recovery will get the job done. That button combination is there just in case you can't boot into system at all. But by default, what that does is also the same, calling recovery to duty.
However, if you want to boot into Download/bootloader or recovery modes without using those methods, you can use the Quick Boot app to get the job done with ease.

Restore gmail account to Android
I just got a new Motorola Droid Turbo 2, Android 5.1.1 I have 2 gmail accounts & 1 just disappeared (it was there as of yesterday), altho I can access it from any computer. I have tried to add the acct by doing the obvious: "Add Account" on my gmail page, and "Add an Acct" in Android settings w/no luck. Both seem to be treating it like I'm trying to establish a new acct not an existing one.

Storing this for future reference and to help others.
Summary

desktop computers fine
android mobile phone

1 gmail account accessible the other not
had removed google authenticator 4 months ago on previous mobile

new mobile 1 month ago

everything syncing and accessible till recent google account password change

Actions

tried cache apps deletes, reboot
tried google resync
then tried android mobile google account remove of non-accessable gmail account
successfully installed google authenticator on mobile by switching to working google acount via desktop computer
then tried disable 2 step authentication
then tried changing google account via lastpass (wanted one common password for both google accounts) which failed
changed google account password successfully via google account. Rebooted mobile. Waited 1/2 hour for servers synching.
Now able to logon to both accounts on mobile.

CM 12.1 Nightly Mako Home Button Not Showing
When I go to landscape mode on my Nexus 4 with a CM 12.1 Nightly, the home button gets cut off, and the other buttons are not showing. How can I fix this?

Give us the screenshots of both portrait and landscape mode. Which nightly build are you using? Is it official or unofficial?

It is an official nightly build, and updating it doesn't change it

Screenshots are still required though.

This is a system ui issue.
A simple restart will definitely fix this problem.
If it doesn't, make sure to do a clean reflash again.

This doesn't work at all.

Resetting Nexus 6 requires previous account

Same wifi
previous person registered on the phone left
I reset the phone
after language selection (and wifi selection), I get the problem

Device says
This device was reset. To continue, sign in with a Google Account that was previously synced on this device.
Does anyone know how I might fix this problem? It's an important test phone for me.
Again it’s the same wifi as previously.
I looked How to bypass "Verify your account" (Factory Reset Protection) but Nexus 6 does not have such a home button.

This is an anti-theft policy put in place by Google. There is not supposed to be any way to use the phone unless you have access to a prior account used on the device. See the Nexus documentation.
The user with access to a prior account should remove that user to allow future access:

To turn off device protection, remove your Google account from your device. If you have Developer options enabled on your device, you can also go to Settings Settings > Developer options and check "OEM Unlocking."

Reboot to the Bootloader, see my previous post, and plug it in to a computer. On your computer, install fastboot (google "how to install fastboot on ..."). Then, open a terminal and type,

fastboot oem unlock
fastboot oem lock

If this does not work, download a nexus 6 factory image here, and download the latest one. Double click it, and then run:

cd ~/Downloads/name_of_file
fastboot oem unlock
sh flash-all.sh
fastboot oem lock

Please note that this will void the waranty.

Please delete both of these incorrect answers. Only entering the prior account will work. Once this is done, use the factory reset from the Settings menu.

Why does unlocking bootloader affect camera quality on some devices?
Sony announced it officially that unlocking bootloader, since it will remove DRM keys, might affect camera quality.

For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality. For example, noise reduction algorithms might be removed, and performance when taking photos in low-light conditions might be affected.

I tested it on my LG G3 (D855) too and I realised there is a certain drop in the camera quality. What causes it?

For Sony's specific case, it's because Sony has proprietary technology (X-Reality color management, BIONZ image processor, active noise cancelling techniques) for its stock camera that uses DRM security keys. When the bootloader is unlocked, the keys that reside on TA partition are removed, thus disabling the features. The use of proprietary technology also means that those features are unavailable on 3rd-party apps, regardless of locked bootloader or not.
Quoted from XDA Developers - Restore Functionality on Unlocked Xperia Devices,

If you unlocked your bootloader on a recent Sony Xperia device, you probably know that the potential loss of warranty is not the only disadvantage you have to accept. Another fairly hidden issue is related to various proprietary features such as the X-Reality color management, BIONZ image processor and the active noise cancelling techniques.
Once you decide to unlock your bootloader, the process also removes a piece of data referred to as the DRM keys. These are tied to various services (such as streaming video and the like) offered by Sony but are also required for the features mentioned above to work properly. Put simply, once the keys are gone, you’ll face issues such as decreased low light camera image quality and the lack of the X-Reality mode.

Note: I can't say for LG's case, since I couldn't find any issue with unlocked bootloader and camera. The only things I found were LG G3's stock camera also use proprietary technology and LG G4's camera is not affected by unlocking bootloader, which seems conflicting this answer if the issue is solely caused by DRM.

Can we install Amazon video app on external SD card?
I am an Amazon Prime user. The Amazon Video App allows us to download the video to the phone so that we can watch them without wifi connection. I have a Samsung S5 phone 16G version. When I download a movie, the amazon app size increases. I think that the app somehow hold the movie data within itself. Normally, I can only download 2 movies into my phone because I have many apps and the system itself talks space. May I know whether there is anyway to put the app on SD card?

In July 2016 Amazon upgraded their Amazon Video app... now when downloading a video it prompts you if you want it saved to your SD card (if you have one installed).  -Settings- in this app also has an Internal/SD Card toggle switch where to save. The negative is any videos already saved to Internal memory have to be deleted and re-downloaded to the SD Card if that is where you want them.
This whole subject freaked me out a bit as I just bought 6 seasons of Game of Thrones only to think I could not put on my (newly purchased) SD Card...  My lucky day that this app upgrade just happened within about the past 30 days.  The Hi-Res download to a 80/20 mbps SD card is painfully slow.

Every app has a data folder under /data/data partition that only they themselves can access. Your Amazon app downloads the videos to that folder. What you see as increased size of data is the size of that folder.
Application itself, no matter where it is located, will keep downloading things to folder. If you want to switch this data folder's location to SDcard, then you can use Link2SD to do so.

Have you verified that the said Amazon app download videos into its data directory under /data/ and not under internal/external SD card, most likely in Android/data/PACKAGE/?

@Firelord For DRM reasons, I think SarpSTA is right (I haven't checked it, though). Compare with Google Books/Music/Video, same stuff. If data would be stored on external SD card, they'd risk people extract it using a card reader – so unless every download is encrypted, that's rather unlikely.

IPV6 address on wifi
I noticed the other day that my Android phone (Moto X first gen running lollipop) was reporting having an IPv6 address.
After a bit of investigation I discovered two things

It only shows when connected to WiFi, not cellular data.
The address it is showing is a loop back address starting fe80:

I am a bit bemused as to why this is. Why would it be enabling IPv6 and why would it be reporting it's address is a loop back address?

Is the DHCP off in your router? If I go by this article, the address is a link-local address and appears when all methods to issue a routable address to a host fails.

fe80: isn't a loopback address, it's a link-local address.  Every IPv6-enabled network interface has one, and it's in addition to any global ("real") IPv6 addresses that the interface may (or may not) have.  What you're seeing is entirely normal and expected; it just means that your phone supports IPv6 on WiFi.  (Presumably, IPv6 is enabled so that the phone can take advantage of it on networks that actually provide IPv6 Internet connectivity.)
The IPv6 loopback address is ::1.  You'll probably see that address on the lo interface, along with the IPv4 127.0.0.1 loopback address.

No decimal input on numeric field when using Google Sheets on phone
In Google Sheets, when I add a number (e.g. 1.01) using the text keyboard and hit Enter, this numeric keyboard pops up as a default because the field is numeric. However, I do not have a decimal option, so I switch back to text keyboard, and we start over on every cell... or I could switch back and forth just to get the decimal, which is also insane.
On a tablet, in the white (extra options) the last one is the decimal point, but on the phone, it isn't there. I'm using Samsung Galaxy S3 and there is no decimal point on numeric keyboard.
How to input a decimal point with numeric keyboard?

Screenshot (click to enlarge)

What is your device model? And what keyboard are you using? It seems it's impossible to do (1) and not sure about (2), so do you mind changing keyboard?

I'm quite sure the Google Keyboard, SwiftKey and ai.type keyboard apps have the decimal point. Use any one of them. The 1st 2 are free.

@TamoghnaChowdhury This is also what I was thinking and a great suggestion. Perhaps add this as an answer if the keyboards show the decimal point by default on the numeric keypad. Be sure to include Play Store links!

@Great answer! Don't worry about pictures...

@AndrewT. Samsung Galaxy S 3

This was fixed after app software update

What software update? OS or app? Clarify and state relevant versions and other information if possible.

There may not be an exact solution to the problem as you posted it, but there are possible workarounds. Android's primary strength is it's customizability and modularity, so if one (your stock) keyboard does not satisfy you, you're welcome to switch it out for another which does.
I know of 3 keyboard apps off-hand that have a decimal point in their numeric keypad. These are:

Google Keyboard - The officially recommended keyboard app for Android, and the default for Nexus devices and devices running Lollipop or above (as the AOSP keyboard). Very clean and doesn't deviate much from AOSP. Completely free.
SwiftKey Keyboard - a very popular keyboard replacement app (some might even say the most popular). Highly themeable. Free with in-app purchases.
ai.type Keyboard - Another very popular keyboard. Supposedly has very good text prediction, and also high themeability. Free with in-app purchases, Pro version removes ads.

I recommend these keyboard replacement apps to the OP as I have used them myself and know that they (when I used them) provided a numeric keypad with a decimal point, as the OP requires.

OpenVPN Connect (Android): How to allow local traffic to bypass VPN
I use the OpenVPN Connect app on my Android devices to route my internet traffic through commercial VPN Service providers (Private Internet Access and IPVanish).
I can access the internet through the VPN with no issues.  Problem is, while I'm connected, my device cannot communicate with other devices on my Local Area Network (LAN). For instance, if I use ES File Explorer app to open a folder on my Network Attached Storage (NAS), I get a timeout error.  When I disconnect from the VPN, everything works.
Another VPN client, OpenVPN for Android, does not suffer this limitation. It appears to be able to distinguish which packets to send to the VPN server, and which packets to send to the LAN devices.  Digging through the options for this app, I noticed a setting titled Bypass VPN for local networks that controls this behavior.
Unfortunately, for my use case, I cannot switch to the OpenVPN for Android app.  Its UI for connecting/disconnecting is too complex to be useful on my streaming box (Amazon Fire TV) where I have only a remote to navigate (no mouse, no touch).
Is it possible to configure the OpenVPN Connect client to bypass the VPN for LAN communications?  Alternatively, is there an OpenVPN client for Android that has this feature and works reliably and is easy to use with just a remote?
I have looked for answers in the OpenVPN help forums and found that the question has been raised (https://forums.openvpn.net/topic16773.html) and raised (https://forums.openvpn.net/topic19489.html) but never answered.
Please help if you can. I have no networking experience so please be explicit.

I concur and would also like to know the answer to this. I have trawled the forums but there seem to be no answers on this. OpenVPN Connect (the official app) seems to have no routing option to allow for local traffic. As mentioned above, OpenVPN for Android by Arne Schwabe has the routing option 'Bypass VPN for local networks'. It seems strange that the official app does not support this.

Why can't install 15MB app when I have 180MB free?
I want to install an app from Google Play, where it's said it has 14.99MB.
However, when I click on Install, it says "Insufficient storage".
When I click View Storage, there says 180MB available.
Why can't I just download it to the SD Card?
As I see, this has been a persistent error, though in other posts people are talking about 15 MB of free space. I got more than 10 times that, so isn't it strange?
Also, the Storage screen don't show the available space as part of the bar "Device Memory", above. Does that happens with anyone else?
I'm using a Sony Xperia.
Thanks in advance.

Please take a look into our insufficient-memory tag-wiki, most of your questions are already answered there. And no, it's never 15MB free – it's at least 25MB free and more likely 10% (don't blame me, I didn't make that rule).

Thanks. What I meant is that, in the other posts I saw, people were complaining for having far less free memory than I have, and they couldn't install a small app (< 1MB in their case).

Yes, I know. This issue is asked about here almost once a day. See the "Related" section next to your question for examples, or click the insufficient-memory tag below your question (364 posts – and not all questions about this issue used this tag, so it's definitely more).

Give us the output (screenshots) of Diskinfo. Mention the exact name of Android model and Android version.

Diskinfo: 875KB on my device. Device memory available: 194MB. SD Card: 7.96GB available. It says there's no room to install Diskinfo! Android sucks, that's all! Android version is 4.4.2. What do you mean with Android model? Don't you actually mean the device model? It's a Sony Xperia E1 D2104.

Unable to flash zip made by ZIPme app
Device details:
YU Yuphoria
Android 6.0 Marshmallow (AOSP custom firmware)
Root Access: Not yet
Bootloader: Unlocked
Recovery: TWRP v2.8.7.0
I made a flashable zip of my apps along with their data through this app while I was on CyanogenMod 12.1 (with root access). Now when I try to flash that zip file in the ROM I mentioned above, I'm unable to do so.. I get an error:
ZIP file is corrupt

I'm unable to make out what's causing this error.. I could assume that the app which I used is not a good option for me to make zips, but many users have tried that app & gained success.. Please help me troubleshoot this..

The very obvious first question is: Have you tried to unzip manually, e.g. on your computer?

Of Course yes. The zip contained three folders: one was META-INF, one with the app data which was stored on the SD Card, and the last one was named data, which contained two sub folders, one with the app apk, and the other with the app data which is stored in the device /data partition.. I just can't flash it

Can you put the updater-script content here ?

@lord-ralf-adolf I've copied the content of the updater-script & uploaded it as a text file: http://www63.zippyshare.com/v/i4ffcGPO/file.html

ok every thing looks good in the script ,I still think it's a zip file problem so ,did you try unziping then ziping then flashing ? zip the file with 7zip or winrar make sure you zip it as .zip with a low compression level for better compatibility

@lord-ralf-adolf I tried unzipping & zipping again with 7zip.. but still no success.. same error.. "Zip file is corrupt"

ok I see can you test this dummy zip I made ,it does nothing just flash your first zip that say curupted then flash my zip and then copy the recoveryX.log from your sdcard and show them to me

@lord-ralf-adolf where is the link to that zip you made?

oops my bad sorry for that here you go https://www.dropbox.com/s/ynsqy5z1gahy6zg/DummyZip.zip?dl=0

Mobile Hotspot timer without root?
I have a Moto E (2015) and I have a hotspot plan that I let my family use. The Moto E has stock Tethering support. However, there are some limitations.
The hotspot would not turn off automatically. This could potentially create two serious problems. One is that the tethered devices continue to tether even when they are at a place with free Wi-Fi. The other issue is that I could forget that my Wi-Fi was used for hotspot and ended up using my Mobile Data when free Wi-Fi is available.
The best I could come up with is manually setup a reminder every time I turn on Hotspot but it is rather cumbersome and it requires me to manually turn hotspot off. I searched around for this topic but I don't see any solution. Would like to hear some better ideas.

@Firelord The latter one is easily possible with Tasker.

I would be perfectly happy with a time based trigger.

There are many automation apps that can help here.
MacroDroid
It is a free/paid app. Free version would suffice for the goal however.
The macro would be:

Trigger: Hotspot Enabled/Disabled → Hotspot Enabled

Actions:

Wait Before Next Action → set the timer per your needs
HotSpot On/Off → Disable HotSpot

Constraints: none

This method, due to some technical limitations, may not work on every Android version, though I had success with both Android 4.2.1 and 5.0.2

Automate
It is a free app with in-app purchases. No purchases are required to achieve the goal however.
You would need to create a flowchart like this
(Click image to enlarge)

The hotspot blocks can be found under Connectivity section and Delay is under Data & Time. Set the Delay to the timer you need.
Once the flowchart has been created, make sure to install the permission it needs

Start the fiber and there you go.

Unfortunately, neither solution worked on my Moto E. It seems the API to enable/disable Hotspot is private and not supported on all phone.

Ahh, too bad. Could you tell me which Android version are you using?

I'm running 5.1

With respect to your first comment, I suppose that's the case for your device because I've now successfully  tested my solutions on Android 5.1 ROMs as well.

In continuation of my former answer, some other useful automation apps are:
Automagic
It is a paid app with 10 day free trial version. Use the trial version for testing before attempting to buy the app from store.
Alike Automate, it uses the concept of flowchart. You would have to create a flowchart like this
(Click image to enlarge)

The block with rounded edges represents a trigger, the rest are for actions. The app would introduce your with its know-how, so you would know where to look for to create that chart.
Note that Execute Command is executing the command sleep N. Replace N with the number of seconds your timer would have, such as 360 for 6 minutes.

Tasker
It is a paid app with 7 day free trial.

Profile: Event → System → Intent Received:

Action: android.net.wifi.WIFI_AP_STATE_CHANGED
Priority: Highest
leave rest of the entries untouched

Task: (Actions):

Task → If:

%wifi_state eq 12
OR
%wifi_state eq 13

Task → Wait → set the timer
Net → WiFi Tether → Off

The information about the intent and variable wifi_state came from this reddit thread by TremendoSlap. Anyhow, if you monitor the output of logcat when hotspot gets activated, you would know that the said intent is broadcasted with initial tethering state denoted by 12 to final state 13.

Droid Automation
It is a free/paid app. Free app would be enough for our goal.
Create a profile with following entries:

Trigger: Wi-Fi Hotspot state → Become active
Task:

Various → Sleep → set timer duration
Network → Wi-Fi Hotspot → Disable

Everything works fine except that sleep duration cannot be beyond 10 seconds in a task. The simplest workaround is to add multiple tasks with sleep action. It may become impractical to add multiple of such tasks. Hence, you may consider Tasker here.
Under Various there is an option to execute Tasker's task. The Tasker's task would be to wait for N seconds/minutes and turn off Hotspot.

Can i delete old WhatsApp database backup without affecting the chat?
WhatsApp data is taking around 700 mb of internal storage which excludes media. If I delete all the database backup except for the latest one, will my all previous chats get deleted? I don't want to delete any of my chat

No, your chats will NOT be deleted.
Deleting old backups would not delete all your chats but only the ones which you deleted before last backup was created and hence are not in latest backup. So you can keep the latest one without any fear of losing what is important to you.

Like it is said already, the chat is not touched by all these backups. You can delete them without any harm.
The thing is, it won't help you nothing to delete these. WhatsApp will rebuild them day after day till they all are back. You cannot change this backup behaviour of WhatsApp. The only thing to get the backups smaller is to delete your chats and delete the WhatsApp data. Then not restore the existing backup when WhatsApp started first time after data-deletion. But who wants this?
EDIT 2017-04-05: I wrote a little Task in Tasker (need root for it!) which deletes all these old backups each night. This saves me some 100 MB of space :)
I use the Action "Run Shell" with a "rm" command with wildcard.
Works :)

Why is my phone coming on in my pocket?
I've got a stock Nexus 6p and I have noticed several times that the phone has come on by itself while in my front pocket and is waiting for some kind of input.  Furthermore, in some cases it has somehow got to the dialer which has been filled with a long string random digits - fortunately it hasn't actually dialed any of them yet!  I'm not sure how digits are even being dialed, as I keep the screen facing in (as the radio antennas are exposed on the back).
I turned off "Ambient Display" but this is still happening.
My phone is protected both by a PIN and the fingerprint reader, although it appears the dialer doesn't need either one to be activated?
There are apparently some apps which will "prevent" your phone from waking up when the proximity sensor detects the phone is on your pocket, but I'm wary about these without knowing more technical details: for instance, is it really possible to prevent the screen from coming on, or it detecting the screen has coming on with the proximity sensor in the "near" state and then shutting the screen back off?  Are such apps even necessary any more?  This seems like such a fundamental necessity that it would be built into the OS by now!
Is there some feature in Android to prevent the dialer from coming up at all without unlocking the phone?  I can't even figure out how to get the dialer to come up without getting past the lock screen. (Do I have to click "Emergency" from the PIN entry screen? I'm afraid to test that as it might go directly to dialing 911 without further input!)  I don't think I'm accidentally unlocking the phone with my finger as I don't usually keep my hands in my pockets; further I haven't felt any haptic feedback, and half the time I have trouble getting my finger in the right orientation to get recognized when I'm actively trying to unlock the phone.

Do you have the double tap to wake feature ?

@lord-ralf-adolf don't think so... if I double tap the screen it doesn't wake up. Is that what you mean?

yes that's what I mean ,so no double tap to wake is not there ,you installed any apps lately ? is this behavior new or is it there since you got this device ?

How do I disable camera autofocus on the Galaxy S5?
I'm trying to take video with my camera on my Galaxy S5, but the shots are almost always out of focus, or the autofocus will kick in randomly and leave the shot blurred.
I have tried the stock camera app and Open Camera, both have this issue.
The phone is useless to me unless I can resolve this issue, every video has a problem with blurring.
Thanks

Sorry for telling you the truth , but you cant really disable autofocus from the stock camera app...

Can you disable it in some other way?

No worries. I'm furious with the phone company for selling me a terrible phone, but it's not android's fault.

Cant enter recovery mode Galaxy Tab S 8.4
I have an issue on my device (Galaxy Tab S 8.4). I´m either stuck on boot loop (flashed with TWRP that worked fine for months until recently after a restart) or I can enter download mode and get stuck at the "Download... Do not turn off target!"-screen. Cant ever enter recovery no matter how I try... If I let the battery die it boots up into the boot loop as soon as I plug in the power chord. Is my device bricked or whats going on?

It is late to answer the question but for others: in download mode you can connect tablet to pc via usb cable and use samsung kies (windows app) to flash stock rom. And probably problem will solve.

I had the same exact problem. I flashed a Marshmallow ROM from KitKat, not realizing I had to update the bootloader to Lollipop. I got stuck and couldn't get past the boot screen and when I used pwr+vol dwn+home I got the Download...Do not turn off target msg. What worked for me was to plug in my Tab to my pc, start up Odin 3.09 (not sure if the version matters, I didn't try 3.12) and I was able to flash the Lollipop boot loader. The Tab restarted and I was good to go. Hope that helps

Not enough data in question - and not enough rep to ask with comment, do you try to enter recovery by holding volume up + home + power? (You mentioned just letting battery die, which is not going to help any good). You mentioned You can enter download (vol down + home + power) so I'm guessing you know about recovery too.
If You cannot enter recovery even holding proper combination You need to flash just recovery.img, preferably checked and working with your model.

Thanks for the fast answer! Problem is that when I enter Download mode I get stuck at "Download... Do not turn off target!" and cant any further. In the boot loop I can only get into download mode. Have tried getting in to recovery mode with volume up + home + power but I cant get it to work. Tried it when Im stuck in download mode and tried it when I´m stuck at the boot loop.

Yes, but how about recovery mode (You enter recovery same as download, from device turned off, just different keys)? If You tried that from powered off, and failed then its basically reflashing recovery.img in download mode, from PC.

I cant turn off my device at all, thats why I tried to let the battery die out to see if it fixed it (which it didnt). The only time I get into the download mode is when the device is stuck at TWRP-logo. Entering download mode -> stuck at "Download... Do not turn off target!"-screen. From there I can only reboot normally (power + vol down + vol up). Can not go into recovery mode from there either...

You can use a better trick to power it off. Plug charger,  hold power key ~10 seconds, wait for battery charging img, unplug charger. It should be  off. But since You are sure that You  cannot enter recovery there is not much to do,  first You need to be sure that kernel (boot.img) is flashed correctly, and then recovery.img. You might unpack Your ROM and flash those two separately.

As soon as I plug the charger (even when the battery is empty) the device boots up and get stuck at the TWRP-screen... Doesnt help that I hold the power button.

@JakobStrand, consider incorporating your comments into the question because users who may be interested to answer would need that info.

I have exactly the same problem Jakob has described.
The Tab S is stuck in in a boot loop. The power off button has no affect.  Vol Up + Home + Power has no affect,  Vol Down + Home+ Power reboots straight into the boot loop.
The hope was that letting the battery drain to power off, then charge to try Vol Up + Home + Power ( as this should be done when the device is already power off).
The action of charging sends the device back into the TWRP boot loop.
The Tab S had been working great with CM12.1 for many months. But after a factory reset, which I did in order to be able to gift this to someone else, has resulted in this situation.

Gmail not showing notifications on Nexus 5x?
I have been using Xperia U on ICS and never faced this issue. With my 1 week old Nexus 5X I sporadically get notifications for my gmail app i.e. sometimes (10%) it shows notifications but most of the times it doesn't. This also happens even if I am using my phone. So definitely nothing to do with deep sleep. I manage my personal gmail account as well as university email. Please tell me some solution to this problem as I am missing important mails from my university and am considering returning this crappy phone.

Have you restricted background data? Or turned off auto-sync?
If you did either of these, they could be the problem.

Auto sync is on. What is restricted background data? Its on WiFi all the time, and never on Cellular data.

Is Cyanogen fully compatible with Play services and stock android apps?
I am considering the upgrade of my Android Phone to Cyanogenmod as even with root, I am having several permissions problems, OTA updates removing root, etc.
The only reason I did not yet install it is because I don't know if it is compatible with the Play Store, and apps related. As I have alot of apps downloaded through the play store, and an AppData helium backup, I want to know if the backup will be compatible with the apps in Cyanogen.
My helium backup only has the backup of App Data, rather than the entire application source, as it is more space efficient

Samsung Galaxy S5 mini SM-G800F with stock Android 4.4.2 rooted

I am not sure for the backup (especially for system apps), but as long as you remember to flash GApps (Google Apps), you are good to go and all Google Play services will work like normal.

You can actually test this on your own. All you've to do is to make a [tag:nandroid] backup of your current stock ROM using a custom recovery, then wipe the ROM, flash your desired CM version, flash compatible GApps, restore those app backups, restart and see what happens. If it doesn't work, use the nandroid backup to fall back to stock ROM.

@GiantTree I forgot to mention that the App backup is only for the app data, not for the actual application

@TheBro21 for non-system apps I'm sure it works but system apps like SMS or settings may not work.

@GiantTree I think I will go with testing it by dualboot, or with crossed fingers. You can put instructions on dualboot or nandroid backup in an answer

Luckily, Cyanogenmod is in fact compatible with play services. I am not sure about the stock apps that samsung has, as I didn't even bother trying to install them. The adb backup I made before going to CM restored properly. Google Apps are copyrighted, that's why they are not there initially. You can flash the Open GApps package as I found that to work for me best.

Yes, Cyanogenmod is fully compatible with your previous apps.

Ok, thanks for the informations. But I would like some more detail. And also, will Helium backup of apps work?

Why are apps slowing down my phone just by being installed?
I have about 50 apps installed on my phone (not counting system apps). And my phone is absolutely unusable this way. Everything lags so bad that I can barely even enter my lockscreen pattern. I assumed this was because the apps can magically run in the background as services or whatever, but after freezing about 40 of them and making sure that only a very few services were running like whatsapp, my alarmclock app and my firewall app. My phone is still extremely slow.
Why is that?
Back when I only had these 10 apps installed that are running right now, everything worked pretty smoothly.
So what is wrong? A frozen app shouldn't have an impact on performance in such a way. Is there any way to get it fast again?
I've already removed as much preinstalled apps/bloatware as possible and cleaned the system using SD-Maid and used Autorun Manager to disable a ton of receivers that could start some apps. But it is still really slow.

Which Android device and Android version are you using?

Does that even matter? I had this problem on both smartphones that I've owned until now. The current one is an LG G2 Mini, stock ROM, Android 4.4.2.

You could try using Perfmon  to study which app is consuming most resources

if we goona find exactly what is the problem we really need more infos ,like logs ,power consumption , Storage benchmarks ,which apps are frozen full list if possible ,what bloatware did you remove ? ram memory usage ,how many apps are on your SDcard ,what kind of SDcard you're using  ?

How much RAM is free in Running Service ? I experience lag when my phone does not have enough space in internal storage. How much space is left in your internal storage ?

Is your device rooted?

Information provided by you is scant. Requests for information to help surely a solution have not been answered. How then is it possible to arrive at a solution that works?

Sorry. Yes my phones are all rooted and it looks like there is actually only 170MB of RAM free when I close all apps (the normal way). Wtf? My phone should have about 1GB. About Perfmon, is there a free alternative?

Holy crap, my Whatsapp uses 736MB of my RAM. What the hell? Okay that must be the issue. I could probably just delete all my messages, but I don't really want to. I need to search through them regularely. I guess i could make a backup, but I heard that after some time it gets impossible to merge the backed up message database with the new one because whatsapp changes a lot and I'm really scared of that. Any ideas?

Perfmon alternative IDK...It is one of a kind

Since you are rooted, suggest install wakelock detector to see what is consuming resources when screen is off and perfmon to see when it is on.You will at least be able to pin point top issues and then one can take it further. That was my suggestion and I don't have time to elaborate as answer

Your what's app concern would be better addressed as a separate question (do check existing questions ). You can link this question in that to give background. Your concern now on this is only heard by people who carr to read comments

Phones use Solid State Drives (SSDs) for storage instead of traditional Hard Drives (HDDs). This is because carrying and jostling HDDs can cause hardware problems.
Solid State Drives, however, get slow as you fill them up. So when you start to fill up your phone, its storage gets slower. This means that it takes longer to read the code from storage into RAM to execute.
It should also be noted that the description on Autorun Manager says that some apps will just attempt to restart themselves after it kills them. This constant restarting-killing behavior could possibly be even harder on system resources that just letting the background app run, so be careful which apps you kill.
Some background tasks help apps start-up faster too. I can start up a heck of a lot faster if I've already updated my app while you weren't using it. Instead of waiting for my app to get all of the data it needs when you open it, it grabs it in the background and can just display it when you open the app.
Also, if your device has very little RAM, then it can only hold a couple of apps in there at a time. If the apps you're opening have been erased from RAM, you phone has to erase another app from RAM and use that space for the new app.
Basically, there are a ton of reasons why your phone could be acting slow, and it's probably a combination of them that's causing your phone to act so poorly.

I already moved most of the frozen apps to the SD card and it's still the same. Also: As far as I know, SSDs don't really get slower the more data is on them. On my notebook for example I get full read/write speeds until the drive is full.

@Forivin Check my link, the benchmarks don't lie.

My internal storage and my SD card are only filled by about 60% each anyway...

this really shouldn't be a comparison between SSDs and HDDs. They both slow down when close to full, HDD's much more significantly than SSDs

android phones don't use SSD's as their storage that's totally false ,android phones uses eMMC flash storage , slower than SSDs

I go with @sonictt1. I too experience lag in my Nexus 5 when my internal storage has only around 1 GB, I have experienced lag in whatsapp and keyboard

You might be having lots of data, including pictures and videos, and others that is media from social apps, including WhatsApp and FaceBook .. get a back up of that data, free some space,
also delete unnacesiry apps,  like those used for cleanups,
hope this helps you run the phone acting smooth again,

As you install apps, they are allowed to run in the background. This takes up quite a lot of ram, and will slow down your phone. Do not use a task killer, as the apps use even more ram to restart themselves. The only solution is to delete some of the apps. To find the ones using a lot of ram go to

Settings->Apps->Running

Look for the high ram usage apps, and delete them. As a last resort, factory reset your phone.

Enable Hangouts SMS Notification on second user
I'm using Android with a main user and a secondary user account.
How can I enable notifications when I receive a new SMS?
This notifications are apearing in the main user only.
For the secundary account only when I open Hangouts I can see the unread SMS messages.
I've been looking in the Hangouts settings and can't enable this option.
I'm using a Nexus 5 with Marshmallow 6.

In Hangouts have you tried settings -> accounts -> tap on the secondary account -> notifications and check the box "Notifications"?

I think that's the notifications for the hangouts account (that's checked).
But what I want is the SMS notification.
And in the SMS settings I can only choose the sound and the vibration. There's not an option there to turn on or off.
Don't know if there's another system settings for SMS outside hangouts.

WhatsApp contacts doesn't merge with Google Contacts
I can't really reproduce what caused the issue, but all my contacts show up separately, it's like I'm having two contacts with identical name, one in the Google account containing all his phones, emails including his WhatsApp number but not identified as WhatsApp, and another one for each WhatsApp number the contact has.
I thought about deleting all the WhatsApp contacts but I can't seem to find a way to do it.
Here's what it looks like:

I've tried merging accounts on Google and on phone and the system found no duplicates.
It looks like my WhatsApp contacts are stored somewhere on the cloud and needs to be erased then be re-obtained automatically staying as simple contacts, but I haven't found a way to clear all WhatsApp contacts (I have 900 - meaning erasing them manually isn't an option).
I've tried to filter only WhatsApp contacts then choose delete selection but it didn't allow me to do that.

Have you tried manually merging the two contacts corresponding to the same person?

@NicolaBastianello I've updated my question

similar to: https://github.com/WhisperSystems/Signal-Android/issues/4191 and https://android.stackexchange.com/q/133285/55984

I might be a little late, but still, at least for google.
I had the very same problem recently, some whatsapp contacts were separate from original (google / device / doesn't matter). Manual join did not work - phone said contacts joined but they did not.
After some fiddling I found a solution thet worked for me in all cases.
Problem was in phone number format in original contact and in whatsapp. It is possible to store the number either with or without spaces.
Here in Czech Republic these are

+420 123 456 789
+420123456789

in UK it is

+48 1234 567890

+481234567890
etc.

Solution was simple after realizing this, edit all your google contact numbers coresponding to whatsapp and either add the spaces in numbers without them or delete the spaces in numbers which got them.
After that I was able to join manually all contacts with whatsapp contacts.
Hope this helps
JirkaBitr

works but would love some automation.

If anyone else is coming here and still has the problem. And do not want to manually edit the contacts in different country formats. Here is a simple workaround.
Go-to Contacts app. - settings. - Select contacts to display. - Customize. - Deselect WhatsApp contacts.
You will not see what's app contacts separately when searching for contacts.

Editing all the contacts is useless - just try to re-install your whatsapp and you face the issue again (and sooner or later you will re-install when you buy new phone :-) ).
Why it seemed to be helping? Because the contacts were re-sync to your smartphone - you can test it - just add a web page and it will fix the issue as well - the spaces in the number are not important, it just marks the contact for a re-sync.
What helps and much faster is a full re-sync of google contacts to your phone. You can achieve that by simply adding all of them into a new group, which you can revert in next step - 30seconds and everything re-synchronized and working.

Battery level always 42%
I purchased a second hand nexus 5 to find out that the battery indicator is always showing 42% and never updates, regardless of the actual battery charge level.
I tried replacing the battery with the one from my brother`s nexus 5, then replaced the usb port board.
Also tried:

rooting
installing twrp 2.8.7.1
elemenalX 6.0 kernel
Android 6.0.1
Cache and dalvik wipe
Use the battery until phone shuts down

Nothing helps, although the indicator jumped to 83% and to 54% after some actions which I dont remember. Maybe after cache wipe, not sure.
Anyone know how to fix this?

It might be an issue with the battery controller chip on the device mainboard. I recommend that you get the device checked out by LG. However, if the device is usable, you could not worry about this. Also, if a battery stats app shows OK data, it might be an issue with something else, I'm not sure

@TamoghnaChowdhury Thanks. Other than this the device is usable, w hat do you mean by "not worry about this"?  (battery stats apps didnt help).

Battery contains the chip which provides information to fuel gauge hardware and drivers. Since you have already done that, next is to determine if the problem is with fuel gauge drivers/ software or hardware.
Wipe clean your phone (cache, dalvik and system) and flash stock ROM for your phone. Don't install apps. Switch to safe mode, charge  for about three hours (will certainly top the battery) and if the behaviour is same, then it is NOT OS related (yes, try all this with external SD and SIM removed...doesn't sound logical to do this and I agree but for some unexplained reason I had the experience of weird battery reading with SD card installed and reverting to normal when removed)
If this didn't help,almost certainly hardware related. Time to get the hardware checked and repaired

How to make Startup PIN make a loud noise
My phone unexpected rebooted itself this evening while I was cycling.  This was unfortunate, because I was logging my ride with GPS, and my phone was inside a pack where I could not tell it had rebooted.  Worse still, even though the logging app would have automatically detected that logged was enabled and restarted logging, causing me to only lose a couple minutes of data, the device itself was stuck at the boot screen waiting for a PIN.  The reboot happened about one minute into my ride, and thus my entire ride was lost.
I have done some research and have found that the only way to disable encryption on my phone involves unlocking and flashing a new bootloader and reformatting the entire flash, which has risks of its own and I am not comfortable doing at this time.  So barring that I would like some way to know when my phone is wanting me to enter the PIN so it can boot, so that when I am running a logging application I don't lose all my data simply.
How can I make my phone forcibly alert me when it wants this info?  Preferably a loud tone of some kind that would persist until the PIN is entered.
Update: Ok, apparently after a while the device starts making a faint clicking noise, but this is nothing I would ever hear while outside.

Maybe you should try using headphones while cycling? Because I don't think there is a way to increase the volume.

@zackygaurav yeah, i may have to resort to having my app send a periodic "pulse" sound through my bluetooth headset so i know it is alive.  still not great for unattended logging, but it at least works around the issue in some cases.  for now i will probably just reboot the phone nightly in the hopes that this will get rid of the spurious reboots.

Is there a way to send a video signal into an Android device?
I have Samsung 6 and I'd like to use it with Gear VR. I would like to send an external signal into it like my VCR or Laser Disc player (I'm joking I'm not that old, geewhiz). I'm actually thinking of sending a regular HDMI signal into it.
Is there anyway to do this? Even if it requires hacking? I remember at one point it was impossible to send the video signal out an Android device but now it's not so there is hope?

TrinusVR is an app that allows you to stream HD video from you PC to your smartphone, either wireless with some latency, or with a USB cord without latency. Meant for video games but it will stream whatever is on your computer screen. Then you need an HDMI capture device connected to your PC, and you've got a way to port HDMI into your Android. The catch is that it split screens the image for use in VR goggles, but I believe you can bypass that.

My Phone Installed a Duplicate System on Top of Existing One. Uninstall How?
My phone has been randomly restarting by itself and after its last restart, the screen showed the "New Phone" setup wizard like what you'd see when you get a new phone.
I went through the setup process since it wouldn't go away despite force restarting or removing the batteries. Now my media files from my then existing system are invisible when you check gallery, but the internal storage still says it's fully occupied.
It's a Note 4 T-Mobile Lollipop 5.0.1 N910T and it installed/duplicated that same OS version I currently had on top of my existing system (not Note 4's factory android version of KitKat). It installed a duplicate new clean slate of the phone with only the native apps it came with, while the memory still seemingly has my files but are hidden (or encrypted?) and not classified as anything else but just "Others" when you check it in the My Files app. It's no longer asking for my then screenlock password or fingerprints since it's booting the duplicate install.
How do I uninstall only this duplicate system and recover my files? I had some files not synced in the cloud when it happened so I didn't want to do a factory reset yet. I've tried Kies and SamsungSwitch to explore the phone and all the folders would just show up empty yet still say the internal memory is fully occupied (~23GB out of the 24 usable GB). The external microSD's files can be read just fine. Tried calling Samsung and they don't know how either. Screenshot below shows that the phone can see its memory is full but couldn't classify the files in it so it just says "Others" (gray bar; the "SD Card" in the graph stands for the External MicroSD)
When explored via PC (Win), folders are empty (pointing to that duplicate install, while the existing files seem to be hidden:

Screenshot of My Files app showing internal HD is full but could not distinguish what those invisible files are, Gallery is also empty. The "SD card" stands for the external MicroSD files which had no issues and I can access just fine:

Screenshot (click to enlarge)

I'd try to do a full backup of your entire phone contents as is with Kies, save to your desktop computer, then factory reset and start over and use Kies to try and selectively restore the data you're trying to recover.
According to a thread on xda here when using Kies Restore it extracts all contents of the .sbu backup file to C:\Users\{LogonName}\Documents\samsung\Kies\sbu\temp\{NumberID}\{Files Extracted} which you could try to explore and see if you can access the data from there.

Moto G GPS is inaccurate
I am running CyanogenMod (12.1) on my Moto G (first generation) and while using mobile data, the GPS is extremely inaccurate when driving. I use Google Maps driving mode which used to be great when I had an iPhone, but using Moto G, Google Maps always display wrong position.
I even had the GPS mode on High Accuracy but did not change much. Any suggestions?

Apparently it is a known issue with CM 12.1.

How can I play videos on my TV(not smart TV) from my phone
Can I play videos from my Moto G on my Vizio TV via the USB port or HDMI.
If possible, how?

There are a number of devices similar to ChromeCast which plug into the TV's HDMI port and accept wifi streaming from computers/phones/tablets.  Some are quite inexpensive, and a few incorporate a full media computer running either Windows or Linux.  Any of these will let you stream media to any HD TV, even a first year model.
If necessary, you could also use an HDMI switching cable to expand your port count, if all HDMI ports are already in use.

How to delete a Whatsapp group without admin privileges
Today, I have created a Whatsapp group and accidentally left the group. Now the present admin of the group is not able to add me back. Kindly suggest me what to do.

well why is he not able to add you? Any error message?

You can't delete a WhatsApp group unless you're the last person leaving it. If your friend's phone is throwing an error, try getting him to make another member of the group an admin, and then the second admin could try adding you. But deleting the group without it being completely devoid of members is impossible.

As the Admins, you could delete the group. Unfortunately, Whatsapp admins. have recently eliminated that option, and without notice.
I see NO rational in the absence of this feature. If you created a group, you should have that same power to delete the group.

Can't find Smart Lock on Huawei Y6 on Lollipop 5.1.1
My phone is Huawei Y6.

I already have a pin lock.
Enabled Smart Lock (Google) in Trusted Agents.

But I still can't find Smart Lock feature anywhere.

I have a Huawei 4C with EMUI 3.1 (Lollipop 5.1.1) and don't have Smart Lock setting anywhere either. I think it's just that EMUI might have simply overwritten default security settings menu, and now that option isn't accessible from there.

I removed the question on your post. Take note that this is not a forum, but Q&A site. Answer is to answer the question, not to reply to any. However, your guess is as good as mine, since when researching about Huawei, Lollipop and Smart Lock, I found others have the same issue, as noted on this post on XDA

It does have a Smart Lock feature at least on Stock and CyanogenMod build.
On Stock Android (5.1.1): Settings > Lock Screen > Smart Lock.

Are you specific with Huawei y6 or just lollipop 5.1.1 ? because I do not have a lock screen option.This is how it looks on settings..
http://i.imgur.com/DJYsCBV.png

@NirmalSeneviratne PhoneArena says that Huawei Y6 runs on Huawei EMUI 3.1 UI. As much as I know, This ROM is close to Stock Android and it should definitely have that feature.

@NirmalSeneviratne Is there Lock Screen option in Settings?

There is Screen lock & passwords option only, no lock screen option.You can see all options related to security of settings page in the screenshot in my comment.

The same happened to me. Huawei Honor 4x after upgrading to Lollipop the Smart Lock UI Is Missing. After Connecting a new Bluetooth device it had even asked me once or twice if I want to use this device to unlock the phone so there seem to be working in the background but no way to control it. Obvious bug.

Are there any Marshmallow-compatible bluetooth styli?
I've bought a Nexus 9 as a gift for my daughter for Xmas.  After reading that Android M added native support for Bluetooth styli, I'm looking to purchase one as an additional gift. I'm looking for a stylus that is highly accurate and supports varying levels of pressure and palm rejection, like the Wacom Bamboo Fineline 2 or Intuous 2. Those products only list Apple device compatibility, though.
I realise that apps need to be updated to accommodate the new APIs in Android, but can I pair either of these with the Nexus 9 in the meantime?

Try the Adonit Dash. No palm support on Android device though.

please link the app and explain significant use in relation to the question

Using Android Device Manager to determine state of stolen device
My phone was stolen over a month ago, during which time I had already sent a lock request to the phone via ADM.
The device still appears on my list of 'recently used devices' although it is clear it has not been used since being stolen. I am still able to send lock requests though.
I am curious: If the thief had somehow hard-reset the phone back to factory settings, wouldn't it automatically be removed from my list of devices? Or will it simply remain listed here indefinitely until I choose to remove it myself?

The List will remain same even if the thief has done a hard factory Restore So you cannot trace the phone again if he had done a factory reset or flashed a custom/stock OS again Android Device manager is helpful only if he hasn't done a reset to your device better book a complaint using your IMEI number to Police they can help you :)

Getting a hotspot without root
I've read several articles on how exactly to do this, but none of them seems to work. I can't root my G Flex 2 (because I have ZV9), so that route is inaccessible. FoxFi initializes but I get a warning that I need to subscribe to a hotspot service. Is there any workaround for this?

Which Android version are you using? Why not take the native (built-in) hotspot feature – is it missing from your device?

Yes, but I receive a notification that I need to subscribe to the hotspot service.

Maybe your provider detects the "tethering" and wants some extra money. The built-in hotspot feature requires no subscription. Funny that USB tethering works; have you tried the built-in variant of that as well?

Didn't even know there was that option. New to android.

Thought so – hence I've mentioned it. An app is not always the only solution :) Guess I should make that an answer for you to accept? Does it work for you?

I downloaded Pdanet+ and used the USB option, not the Wi-Fi one.

I think I may have flagged in haste. Is this an answer or you intended to reply to somebody?

Answer. Solved my issue

HTC EVO TWRP No Kernal Installed TWRP
I have a freedom pop HTC EVO LTE (Jewel), and I have erased the image and no OS is installed.  I have TWRP installed and I can boot to recovery, but I am unable to flash any ROMS.  I have tried MeanBean, but the kernel install is not working and errors out.  How can I get the Kernel and or a new ROM installed so the phone will boot?
TAMPERED
UNLOCKED
S-ON
HBOOT-2.1.0000

"but I am unable to flash any ROMS" -- can you elaborate on this part? Which TWRP version are you using? Is it official or unofficial? What ROMs have you attempted to flash so far?

I have tried cyanogenmod, and meanbean.  Cyanogenmod fails with error: can't extract binary.  Mean bean fails with error above (can't install kernal).  I am unsure what official vs unofficial twrp is.  The phone came with it on it from freedom pop.

It appears that for Meanbean ROM, data and system flashed successfully and some problem occurred when flashing kernel. Do this: in your PC, extract boot.img from Meanbean ROMs zip and copy it to /sdcard of device. Then in TWRP, go to Install, select IMG instead of ZIP option at the bottom, find and select boot.img under /sdcard/, and when asked for, choose boot partition. Report us the results.

Do I flash meanbean rom via zip after the boot.img?

This time: wipe System, data and all caches. Then flash Meanbean ROM. It would flash data and system fine (if I trust the screenshot) but fail at boot. For boot, follow my earlier comment.

I do not have the option to flash .img from twrp. looks like that is not available until 2.8.4.0

Let us continue this discussion in chat.

How to use burst / slow-mo features on Nexus 6p?
The Nexus 6p is supposed to have some cool features dealing with burst and slow-motion (high frame rate) capture, but all my searches for how to use these features are turning up an explanation that the features are there, but not how to use them.
It must not be too difficult, because I inadvertantly took a burst capture when I was trying to take a single picture.   A bit of research suggest that "holding down" the shutter button (volume button, apparently) shoots a burst, which is unfortunate if I just want to make sure I really pressed the button and only want a single picture.  I can't find out a way to disable this if I really don't want a burst of images at a particular shoot.
But I can't figure out at all how to use 120fps or 240fps capture, or even how to choose the frame rate.  How do I do this?

This is for Google Camera v3.0 and up:
Video

Open Google Camera app
Swipe from right to left for Video mode.
In the top right, touch the icons to turn features on or off:
Slow motion: Set slow motion to 120 fps or turn off slow motion.
Note: On Nexus 6P devices, there's an option for 240 fps. 240 fps produces a higher quality slow motion video than 120 fps, but requires more storage space on your device.
Flash: Turn flash on or off, or set to auto (for auto, you'll see an "A" in the icon).

Photo

You can choose what Google Camera does with your photo bursts. There are two settings you can turn on or off:
“SmartBurst”: Automatically save only the best photos in a burst.
“Auto-generate creations”: Automatically turn your photo burst into an animation or collage.
To turn these settings on or off:
Open Google Camera app.
At the top left, touch Menu  > Settings > Burst settings.
Next to each setting, touch the switch to turn the it on or off.

Galaxy Tab 4, WiFi strong but internet drops constantly
I'm having this issue with my father's Galaxy Tab 4. He can be just feet from the router and even though the WiFi is strong, the internet keeps dropping on his device.
Even my crappy Dell Venue 8 almost never drops the internet despite the issues it came out with.
I already updated the Galaxy's firmware and didn't fix the issue. I found this is a documented issue in other sites but the Samsung link they were giving to troubleshoot this issue was no longer working.
Any help will be greatly appreciated, thanks!

This is one of many gripes I have with my Samsung Galaxy Tab 4 7.0. Samsung really cut corners on this device, omitting a lot of features and skimping on hardware. I generally like Samsung devices but have found that they certainly have "grades" of their products. I personally have a Galaxy S3 phone,  Galaxy Tab 1, 2 and 4 7" tablets as well as a few other appliances. Basically, anything that is "inexpensive" from Samsung is cheap garbage, while anything that is "expensive" is decent. The Galaxy Tab 4, unfortunately, falls in the "inexpensive" category.

This is a known issue to users but Samsung won't admit it. I have a Galaxy Tab 4 7.0 and have the same problem. I have read a lot of other users experiencing the same issue.
I emailed, chatted and spoke with Samsung customer service about the issue. After a lot of back-and-forth, I finally set up a service ticket where I sent them my tablet, they replaced the entire motherboard, and sent it back to me. The Wi-Fi is integrated into the motherboard, and replacing the motherboard didn't fix the problem. This is the only device I use that has this issue, and it happens when connected to other networks as well (not just my home router, NETGEAR N600).
Basically, the Wi-Fi in the unit is garbage. The device shows that the device has a wireless connection, shows the SSID of the router, and shows full-strength for the signal- but the internet connection just stops working. No rhyme-or-reason, either. It will happen in the middle of doing something after working perfectly for hours. It normally won't fix itself, and the easiest way I've found to reconnect is to just cycle the Wi-Fi off and then on again.

Actually the Wi-Fi is a good Wi-Fi. Not crappy. I spent over a year and finally found the issue of WiFi turning off.
Try this solution.
In setup go to - more networks → mobile networks and choose connection optimizers and check to remove check mark from box.
In other words, whereever your "connection optimizers" is located, turn it off. See if this works.

The “Optimize Networks” aspect seems the issue. As described above, disabling that option resolved the issue. Thank you for that!

Why does 4.4 support infinite Bluetooth visibility duration, but previous versions don't?
I'm building an app that forms a network using Bluetooth. However, Android versions less than 4.4 do not support infinite Bluetooth visibility duration. Every x amount of time (usually an hour), the app has to prompt the user to enable Bluetooth visibility. In 4.4, you can go into the Bluetooth settings and select "Never timeout" for Bluetooth visibility.
What changed between Android 4.3 and 4.4? Why didn't Android 4.3 support infinite visibility? Why does 4.4 and higher support infinite visibility now?

What do you want to achieve where the explanations of "why" and "when" and "what" help you with? It seems your question is off-topic here for multiple reasons: 1) this site is for end-users (no dev questions), 2) answers would be "primarily opinion-based" (the"why" part), and 3) it's "unclear" what issue should be solved that way.

Have you proven this in all situation, e.g. different devices, different apps, different ROM? Infinite bluetooth visibility can be considered as security issue though, so that should be the main concern. On my Nexus 5, Android 6.0.1, there's no visibility setting at all; there's only "Nexus 5 is visible to nearby devices while Bluetooth settings is open".

How do I back up my samsung S5 data.
I have a Samsung S5 and without no reason the screen has stopped working, its totally black the lights are still active. I have taken it to the mobile retailer and they have tried to reset it by taking the battery out etc but with no joy its not fixed the problem. They have said it needs to go for repair. But I have photos on the phone that I would not want to loose. I was advised by the shop to download Kies onto my lap top and then I could back up my phone data. Having downloaded the software today and plugged in my phone I am still left with the problem of unlocking the phone with a totally black screen I cannot see the keyboard on the screen to type in my password. Therefore my question would be how can I unlock the phone with a totally black screen?. And is there a way to save my data and my photos?

Welcome to the Android Enthusiasts! Though it's probably not a "dead screen" issue, results are much alike. Please take a look at our broken-screen tag-wiki, there's a data-recovery section which might be helpful in your case.

You can definitely back your data up. Even if the screen is broken or black.
First, boot your S5 into recovery mode like this:

Switch your Samsung Galaxy S5 completely.
Boot into Galaxy S5 recovery mode by pressing and holding Volume Up, Home and Power keys at the same time.
Release all three buttons when Samsung Galaxy S5 screen flickers and the main screen of Recovery mode appears.

Your phone should now be in recovery mode. If your phones' screen doesn't show any signs of life during this process like some sort of flicker, repeat the process and check through adb with
     adb devices

until it shows your device id.
Once it shows your device id, enter the following in the command prompt
    adb shell
    echo "persist.service.adb.enable=1" >>/system/build.prop
    echo "persist.service.debuggable=1" >>/system/build.prop
    echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop
    reboot

Once you've completed that, you can download a free software that when run on your pc allows you to control your android device. Including touch response and swipe for screen unlock or password entry. The software is available at the link provided. I've personally tested this with multiple android phones including s3, s4, and s5 and it does work. (kids can be dangerous around phones :/).
Hope all this helps

Boot S5 into Recovery
Control device with broken screen

Many thanks for getting back with a reply to my question. But the screen is totally black and does not come on or illuminate, it makes all the right sounds when turning off and on but the screen still appears not to have life. I don't know what else to do sorry I do not understand the adb device shell information you have very kindly shared.

Basically, the adb shell enables USB debugging on your device. Since you stated that it isn't enabled. Add long as your phone vibrates when you press all three buttons, then it should work

Thanks Steve C. I am sorry not too sure what I have to do next do I need to download a program to enable USB debugging.

No. You can enable debugging through the adb command prompt like above then download a software that let's you control your device from your computer. If you lived in LA, then I would just do it for you

How are certs validated against default trust store?
Through some reading, I have a fairly rough understanding about how https works with Android apps, especially how are certificate validations done. Some of the resources that I referred to for gaining this understanding would be :
Validating certs in Android
SSL in Android apps
Validating SSL - Android
As per my understanding, I could roughly say that apps can validate against :

The default Trust Store that Android provides - which has a list of all the CA certificates that are by default trusted by the OS and hence by the browser and the app itself. This is the same list of CAs that can also be seen in Settings -> Security -> Trusted credentials (in JB+) or system/etc/security/cacerts.bks (in Android < JB)

OR

Developers can choose to define their own custom keystores and make an SSLSocketFactory with them to trust their custom trust store.

My question revolves around the first case described above. In most of the places that I could read about it, I discovered it mentioned that for validating the certificates against the default Trust Store, the developer does not really need to do anything explicitly. Just hit the https end point and play on with the HttpsUrlConnection object returned.

The certificate validation itself is internally (by default) taken care of by Android OS.

Now I would like to know how exactly is the above (highlighted) done ? What is the API/internal method/anything else that Android actually calls to do this certificate validation ? Where can I find this information ? One approach I can think of is to go through the Android source itself, but I have no clue which part of the code does it (and plus it would be a lot of efforts).
Please advice.

How to connect a Motorola Xoom 2 ME (MZ607) on fastboot mode to a PC?
I am trying to connect a Motorola Xoom 2 ME (MZ607) on fastboot mode to my laptop running Windows 10 as per described here:
https://goo.gl/ln57PX
When the system loads, Windows recognizes the device. Not on fastboot, though. Motorola usb drivers and Android SDK are installed and updated.
Is this normal? If not, how to solve?

The motorola website behind the link expects me to sign in to access the resource. Consider providing an alternative way to access the resource without the need of user credentials.

Actually, the issue I attempted to describe, and get help with, was the issue of fastboot oem get_unlock_data on the device (tablet) on fastboot mode.  After posting this question I realized that if I try fastboot devices, it gets listed.

Consider self-answering the question in that case.

I tried reaching out for Motorola live chat and they said my device isn't unlockable... So, tough luck!

Problem downloading a game
I'm trying to download Clash of Clans from Google Play, as I always did. My phone is a Samsung Galaxy Core 2, and the Android version is 4.4.2.
The download starts but when it is done appears a message like this:

Application cannot be installed in the default install location

I think you set default install location to SD card and clash of clans can not be installed on SD Cards , change the default path for installing apps in settings and try again .
Update 1 :
May be you have not enough disk space in Internal Storage . Try to remove some apps and install again . sometimes a restart after clean up is necessary .

I have not SD card, and neither can choose the default path for installing apps.

Will wipe request from Android Device Manager affect replacement device?
I had a Samsung Galaxy Tab 4 stolen, so a remote wipe was sent from Android Device Manager. I have a spare tablet of the same model that I need to set up with the same account as the stolen one.  When I sign into the Google account on the new device, will the pending remote wipe command affect it, or is that request somehow tied to the specific device it was originally issued to? I'm only concerned because the device is only identified by model number in ADM, rather than MAC or serial, so I want to be sure ADM won't send that command to the next thing signed in to with that Google account.
Thanks!

Short answer
No.
Some background
As you can have multiple devices associated with the same account (even if they're all of the same brand and model) and still target them separately, there must be an identifier. Logical conclusion is that identifier being the GSF1 android_id. When you register your "replacement", a new android_id will be created for your specific installation2, and stored with the device's configuration. This serves as device identifier for all related operations/interactions between your device and Google services, e.g. for GCM3 and Google Play (apps).
Hence I'd say it's safe to assume the same is used by ADM4, as it's part of Google Services as well. So as long as you don't restore a full backup of your old device, but register e.g. via the setup assistant, your replacement will get a new android_id and thus not receive the "wipe request" addressed at a different android_id.
Another proof to that I've just found on Reddit: Someone had setup multiple devices using the same Nandroid backup taken from a fully configured device, and hence with the same android_id. Result was ADM seeing them all as one device, always "communicating" with the last-used device.5 The issue was solved by resetting the ID.
References for further investigation

XDA: What is the Android Device-ID?
SO: GSF ID KEY (google service framework id) as Android device unique identifier
Reddit: Multiple devices with the same android ID

1: Google Services Framework
2: This is done whenever you register a device, i.e. associate it with your Google account
3: Google Cloud Messaging, e.g. used in the SE app to notify you that you've been mentioned or got an answer to your questions
4: Android Device Manager
5: Quote: it seems like the last device booted is recognized online, the other one isn't

Unbrick Samsung Galaxy Core Prime SM-G360V
I need to know how to un-softbrick the Samsung Galaxy Core Prime. I don't know how it got bricked, I was just asked to fix it. It looks like a bootloop issue. The Product name is SM-G360V. I have already attempted flashing TWRP on it with Odin3, but it fails saying SECURE CHECK FAIL : recovery and the next line is Custom Binary(recovery) Blocked By R/L. I have no idea how to flash a custom ROM (of which I can't find) without a custom recovery.

Can't you hard reset it?

@SarpSTA No, It's in a boot loop, and I cant get in (factory) recovery for some reason. Removed battery, tried the following: Volume down, Power, Home = Download mode. Now, Volume up + Power + Home should equal = recovery, but it won't work.

Turn it off then hold volume up and down and power and wait until it flashes on then flashes off. Next, let go of those buttons then press them again. This should open the maintenance boot menu, and you can factory reset, boot to safe mode, or normal boot, or debug mode I would either boot to safe mode, or reset it. Cheers.

Jake, Hard reset won't work. My friend tried to install a custom ROM. Hard reset will just reflash the broken ROM.

Try to reflash an original rom:

Download the correct rom from sammobile.com
Turn off the device
Press volume down+home+power on for 5 seconds
Press volume up(to enter in download mode)
Connect the phone to the PC
Flash the correct firmware with odin

Doing this I unbricked many Samsung devices.

Use Samsung Smart Switch to Reset to Stock Firmware (I have done this in the past):

Download Samsung Smart Switch for PC
Run it
Remove battery from phone
The device's information is on a label inside the battery compartment at the back of the device. Copy this information into a notepad.
Put the battery back in
Boot to Download Mode (Vol Down + Home + Power)
Connect to PC
Select Emergency Software Recovery
The application will provide instructions from there
Enjoy an unbricked device :D

NOTE: Remove SD card so it doesn't get wiped. I'm not sure if Smart Switch will wipe it but remove it anyway.

Next time you flash a custom recovery enable OEM unlocking in Developer Options.

Why do some bookmark icons have a red background in Firefox?
I have Firefox for Android installed on both my phone (Nexus 5X) and tablet (Nexus 9).
On my phone, some bookmark icons have a red background:

Whereas on my tablet they appear "normal":

What does the red background mean? I couldn't find an explanation online. Even on Mozilla's help website the YouTube icon has a red background.

This explains it as a site having RSS feed. Possible reason it doesn't appear on your tablet is configuration of browser? Try with identical browse settings as on your phone

It's a small cosmetic feature of Firefox: dominant color as favicon background.
To put it simply, Firefox will try to calculate the dominant color of an icon, and apply it as the background. Here is the screenshot of the feature while it's WIP (might not apply to current version).

Image credit to Margaret Leibovic
As for the reason why some of the icons have it or not, it might be probably a bug on Firefox.

Downloads not possible after root
I rooted my Samsung Galaxy S5 (Android 5.0, SM G900F) recently with Odin. While I rooted it, I had Kingroot installed. Since Kingroot took over the root management, I'm not able to download files with 3rd party apps (like my browser or whatsapp). I already tried to replace Kingroot with SuperSU, but the script which seems to be the only way to do that didn't work for me. For me it looks like the apps didn't have the permission to write to the internal storage. For some reason downloading apps from the Google Play Store works. I downloaded "Root Browser" and it shows me, that my whole /storage/emulated/0/ is owned by root:root and has rwxrwx--x permissions (the subdirectories too) what seems a little bit strange for me (is that normal?), but I'm not able to change them (Root Browser says that you can't change permissions on some file systems).
I already searched for this problem, but I didn't find anything.
I hope someone can help me with this.
