Is it possible to connect a device to a pc so the pc display is on the device's screen?
Well the thing is i broke my pc monitor so is it possible to connect  it using an hdmi so the display is on the device screen?

What device do you have?

Samsung note 3 android

VNC should be the answer.
From Wikipedia:

Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network.

With VNC, you can control another computer or a group of computers available on a local network.
The procedure is as follows:
Install Real VNC server on your computer, and Real VNC viewer on your Android tablet. Your computer and Android tablet should be connected to the same network; if you don't have a WiFi connection, you can use your mobile WiFi hotspot or USB tethering to connect your computer for which you needn't require mobile data pack.
For your HDMI solution, I believe your tablet support OTG functionality. Buy HDMI adapter and an OTG cable. I believe it should do the job.
I fear the HDMI streaming could go opposite, so VNC should be your choice as HDMI would drain the battery and you won't be able to charge your tablet in between.

I've installed a custom recovery image, but not yet rooted my phone. How can I install SuperSU and subscribe to automatic updates?
I own a Samsung smartphone.  I'm running Android 4.1.2 "Jelly Bean".  I've also installed ClockworkMod Recovery 6.0.4.5.
Each time I exit ClockworkMod Recovery, it offers to root my phone.  I haven't accepted this offer yet.
Binaries are not yet available for the currently-maintained fork of Superuser.  So I guess I'll install SuperSU instead.
OK; fine.  So I want to install SuperSU.  I also want to start getting automatic updates — in other words, as new versions of SuperSU are released, I want the Google Play store app to install them automatically.
Please note that I would rather not boot Android up even once with su installed but with no su GUI installed.  Doing such a thing would be a security risk which I'd rather avoid if possible.
What steps should I take, and in what order?

Chainfire (Dev of SuperSU) offers flashable zip. Stable build: https://download.chainfire.eu/396/SuperSU/ or Beta Build: https://download.chainfire.eu/740/SuperSU/

@Firelord: Once I've flashed that Zip file, will I need to do anything more in order to start getting automatic SuperSU updates?

Once you're done flashing, boot into Android, go into SuperSU's settings and under clean-up choose Reinstall. After that, install the SuperSU app from Play Store. As you know, if the app would be having an update, Play Store would tell you that. There you go.

@Firelord:  Ah -- intriguing!  SuperSU has a special option to prepare itself for reinstallation from the Play Store.  (See screenshot.)  I didn't know this, but now I do.  I wonder if you could please copy and paste your most-recent comment into an answer?

Follow these steps:

Download the flashable ZIP for  SuperSU app into your device. It would have both the APK as well as su binary. Choose the stable build .
Boot into the custom Recovery → flash the ZIP → Reboot.
After the boot animation you would see "Android is upgrading" dialog for few seconds. Once booted to Home screen, launch SuperSU app.
Go to Settings and scroll down until you see CLEANUP section.

Choose Reinstall. It would remove SuperSU app from the system but not the su binary.
Go to Play Store and install SuperSU app. Since the app is now installed from Play Store, you would definitely receive updates to the app as long as they are pushed to Play Store and are compatible with your device.

Done!

OTA update limitations with custom ROM?
I want to do some experimenting with an Android TV stick and want to ask some questions beforehand -- that I couldn't find answers to already here on SO.
Any advice is appreciated!

Is it possible to flash the ROM, to start with my customized Android TV launcher? i.e. like Android TV Launcher
If YES to the above, could I have the OS periodically check for updates on my OWN CUSTOM SERVER, to prompt to update the OS / launcher itself?

I am a little confused, because as I understand it from the official documentation, flashing the ROM places restrictions on OTA updates.
Surely I can update my launcher or over-write certain files fetched from my own server?

It would not seem to make sense to flash a ROM for a customized android TV launcher - all you need is something to automatically start your app when you boot - maybe something like https://play.google.com/store/apps/details?id=com.autostart
If you build your own ROM you can make it do whatever you want - including check for updates on your own server - this is probably not trivial, and anyway, where would the upgrades come from.
If you flash your ROM you will no longer get OTA updates as you are no longer running the software associated with the OTA updates.

It highly depends on the ROM you are going to use.
You won't get any OTA updates from the manufacturer. However there are ROMs out there, which use the original (hacked) OTA interface to provide their own OTA updates. So it's definitely possible, but I highly doubt, that you can easily modify that. I've had that functionality on my HTC One for example.
Also some custom roms provide a client from where you can update.
All those updates however are not really "OTA", as they will always have to boot into your custom recovery and install it from there.
If it's just for having a kind of automation I would go for an app like Tasker, AutomateIt or Llama, which provide a great benefit if it comes to automation of things like start up behaviour.

Notification for battery virus
When I was browsing the internet, a new site opened and it said that I have a virus in my battery and that it will then also infect my sim card and everything else, infected by a recent adoult side that opened while I was watching anime. It was android site so I clicked continue and then it asked for my number so I closed it. I don't know if it's real, and if it is, what should I do?

Related SE post

there are no viruses for Android. So just by that you can tell it's a fake
especially, there are no "battery viruses". Neither is there any "security update" for battery firmware, as often suggested. And even if there were such updates, they are not distributed that way (no system updates inform you via browser popups that they should be applied)
websites don't have the facilities to scan your smartphone for that kind of infections. They might be able to tell security holes in your browser (such as "you're using an old version of plugin-X|browser-Y"), but not much more

Knowing these 3 facts, you can rule out 95% of those "warnings" as fakes. If you clicked that anyway, and it asks you for any kind of credentials/serials/system-IDs, that's just fact number 4: No serious updates ever do that.

How unlock S6 Edge When The Finger Print Scanner is Not Working?
My S6 edge was locked by finger print. It was working fine, but today while I was on bath my child was playing with my mobile and by mistake they tried finger print scanner, now my device is locked out.
Now my device asking for backup password but as the password was alphanumeric (12 digit long), I had also forgot it. I have searched a lot on Google and found that either Google account or resetting the device is only solution.
But I can't even use my Google account as my WiFi and/or mobile data was off when my phone was in lock mode. Now because of Google's security system I can't even enable WiFi or mobile data?
So, my question is:
1. Is there a way to make my device to ask for my finger print once again?
2. or is there a way to on my WiFi or mobile data on lock screen?
Because I don't want to reset my device, as I have unsaved data.
Thanks in advance
Best regards

Have a look at this comment and see if his works (http://forums.androidcentral.com/samsung-galaxy-s6/528785-locked-out-galaxy-s6-fingerprint-scanner-passwords-don-t-work.html#post4578198), You probably have already got your phone to work but this is for anyone else who might have the same problem.

Try pressing the power button, till it shows the options like,
power off,
flight mode,
restart,
emergency mode
then select emergency mode. Wait for it to enable. After that, it will ask again for your finger print.

How can I uninstall an app I downloaded, that won't let me uninstall it?
I downloaded this app called 'Photo Editor' (pink logo with letters 'fx' on it) on my HTC Desire 510, I went to uninstall it, but it won't let me do this. Other apps still let me download it. I have tried doing it in settings, google play store, second home screen menu, in the app itself, and none will let me uninstall it. I can't find the app in the play store, it's as if it's deliberately not letting me uninstall it. It takes up 30MB, which is a pain seeing as though my phone can only hold a small amount of data. I have been researching what to do but no one seems to have the same issue. Can anyone help me please? Thanks in advance.

Did the app downloaded additional data after installing ?

How did you install the app? 2. It's true that the HTC Desire 510 ships with only 8 GB of built-in flash memory. But you can insert a MicroSD card of up to 128 GB. Have you already inserted a card?

What do you mean when you say you can't uninstall the app? What happens when you go to Settings > Apps and try to uninstall the app from there?

Have you checked if that app registered as "device admin"? If so, unregister it (removing it from device admins; you can find this in Settings › Security › Device Administrators). An app registered as device admin can block its uninstallation. And avoid that app in the future: a photo admin has no reason for being device admin. If it requests such, I'd count that as indication for malicious intend.

Your phone needs to be rooted for you to be able to get rid of apps preinstalled. But here you say you have downloaded the app later. Have you tried clearing the device cache from recovery and then tried this?

(https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/amp/) If you have root access, you should open a command line as admin in windows/ use su in linux. Then run the above command but without the "-k --user 0" part. Afaik, running it with "-k --user 13" should also work.

It's a pre-installed app from HTC you might be updated from play store .
If your phone is rooted then you can uninstall that app

OP has literally specified that they have "downloaded" the app. This answer is, in my opinion quite invalid.

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

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

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

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

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

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

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

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

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

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

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

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

Why does my phone charges fast when WiFi is on?
My phone is Lenovo A6000+
Original charger and Stock OS.
Edit: it is a two months old phone with no other complaints.

Poor, unclear, and too-short question. -1. Your phone charges faster when Wi-Fi is on, and slower when it is off?

Sorry. But nothing else to add, as you said, it charges fast when WiFi is on and slower when it is off.

I removed the downvote, but please [edit] your question, make it longer, and improve the grammar.

Have you tried using the free apps named "Ampere" or "Trepn"? If so, please [edit] in more information. What did you learn?

Do you have concrete evidence to show us that your device charges fast when Wi-Fi is on and charges slow when Wi-Fi is turned off? Also, which Android version are you running?

I haven't used any apps for that. As I said, its a relatively new phone. And I have no evidence other than I know the phone charge twice the speed when WiFi is ON. Lenovo A 6000+ charge very slowly. It may take up to 2 hours for full charge. Turning WiFi ON reduced at least 30% of that time. All I wanted to know was is this a feature or something like that, as there are no defects.

The only reason I can think of why your charges faster on WIFI, with the information given, is you have data enabled. If data is enabled and WIFI is enabled your phone uses WIFI. However if data is enabled and WIFI disabled, your phone will use data, which on my phone uses 1.5 times more power than WIFI with a good connection. You can disable data by going to Settings>mobile data>off (on some phones it is under the "More..." settings).

Thx, I think that is the reason as my data is always on...

Using external USB camera with Android-based settop box
I have found many offers for selling settop box-like computers based on Android 4.4. One of them claims to have Skype installed on-board and allows to have Internet calls through TV.
For full video conference, a camera is required and since settop box doesn't have one (it is not a tablet or smartphone), we can only talk about external USV camera, connected through one of USB ports to settop box (notice, that we talk about pure USB port, not microUSB with OTG).
While browsing site, I found this answer, that points to an application named USB Camera Trial (Google Play and producer website). But, there are only examples for connecting external camera to full featured Android-based smartphone or tablet.
Will this work with settop box as well? Is Android on board settop box limited in any way or is it as natural as on smartphone or tablet and supports everything as on real mobile device?

I Can't sign in my gmail account. Because am enabled 2-steps verification but i lost my sim card . how can I open my gmail account without my backup phone .? please help me..

When you enabled two step authentication, you should have received a set of backup codes that you can use to log in when you lose access to your account.
If you do not have those codes, or if you didn't receive them, you should ask your cellular provider for another SIM card, although your provider may ask money to send you another SIM card.

Is it possible, that old smartphone becomes slow simply because it is old?
I have 3.5 half year old Samsung / Google Galaxy Nexus i9250. The phone has become so slow after that time, that it is simply being unusable. Launching any application, as simple as Gmail or Calendar takes 2-3 seconds, sometimes even five. Pressing Home button needs 4-5 seconds between press and really showing up main screen of my launcher (Nova Prime).
When I purchased this phone, it was simply lightning fast.
I have about 50 applications installed, of which about half is used (15 from time to time and 10 daily) and the other half, never used or used once per 2-3 months. Because I change my attitude very rarely, I have installed these applications in 2012, when I purchased my phone and haven't installed anything or nearly anything ever since that. I would describe this as changing 1-2 application per year.
Because of above, I can hardly accept, that my phone is slow, because I installed too many applications during that 3.5 year period. We can assume, that I'm sitting on the same apps set for past 1-2 years. It is also hard for me to belive, that 50 apps, of which half is nearly never used is enough to visually reduce performance of such phone. Even though it is quite old, its hardware isn't that weak, as I assume.
I of course did a full factory reset once or twice, installing only the same set of applications, as in 2012, after that. It brought little or no help and little or no performance gain. This has actually "killed" me, because I was more than sure, that full factory reset will return this phone to a level of performance and speed close to the days, as it was brand new.
The only theory, that comes to my mind -- though very strange and unbelievable -- is that my battery is old, its performance is far lower than when it was brand new, and thus it powers all hardware with lesser voltage causing its overall performance to degrade.
I know, how stupidly this theory sounds, but it is the only one, I managed to come with, in given situation.
Assuming that number of installed applications and overall usage style of my phone hasn't changed over past 3.5 years of using it, is there any reasonable reason for why it is so extremely slower than it was, when it was brand new?

Performance has nothing to do with battery voltage. The reason is that the flash memory is "worn" and therefore slower and less responsive.
My Nexus 7 (1st generation) is also very slow now and I have almost no apps on it. You can read more here: Why Android Phones Slow Down Over Time, part "No Solid-State Drive TRIM"

No Solid-State Drive TRIM
The lack of proper TRIM support was the main thing that caused
  Google’s original Nexus 7 tablet to slow down over time. This was
  fixed in Android 4.3, which added proper TRIM support. On Nexus
  devices, updating to Android 4.3 will fix this problem.
If you have an older device that doesn’t have Android 4.3 and has
  slowed down over time, you can perform TRIM by rooting it and using
  the LagFix app. This app runs the same fstrim command Android 4.3 runs
  in the background. TRIM is necessary because of how solid-state drives
  work — solid-state drives slow down over time because flash memory
  cells must be cleared before they can be written to again. TRIM
  preemptively clears cells that contain data from deleted files,
  ensuring things will be as fast as possible when Android needs to
  write to those cells in the future.
How to Fix It: Root your device and run LagFix if you’re using an
  older device. This happens automatically on devices running Android
  version 4.3 and newer.

Why isn't TRIM something that runs automatically? http://android.stackexchange.com/q/117164/100457

It seems, that your answer / suggestion stands completely opposite to my situation, as my (all) Samsung Galaxy Nexus has Android 4.3. If Google added TRIM support to that version of Android, then I have it and the lack of it / Flash memory wear-off are not the case. Your answer is good and valuable to others so I voted it up, but I must consider, whether to accept it or not, as your suggestion clearly does not answer the question (no TRIM issue on Android 4.3).

@trejder In my experience with a Maguro Galaxy Nexus, TRIM does not run automatically.

Is there a way to run the trim command without having root access?

You've likely been updating the apps, and they're using more bloated APIs.
I, personally, don't see a reason every app needs to carry Unicode support, for example.
Facebook would be one of the largest offenders. 3 years ago it took 70MB RAM, now 200 so that it, among other snoopy things many apps now do, can carry its own browser to better track you. It doesn't help they split off Facebook Messenger, which also takes 150MB RAM.
'Flash wearing out' is definitely NOT what you're experiencing here.
Additionally, I think Google hasn't bothered optimizing minfree and the OOM manager, or the app lifecycle management. YouI'll have 500MB RAM free on a 2GB RAM phone and you still get home screen redraws all the time, and apps suspend the second you switch to another. Google is lazy and practices 80/20 too much...
Personally I avoid updating apps unless under duress, and use App Quarantine to keep apps locked down when I'm not using them-- for example, Amazon has 5 apps, and they all like to load up running around doing nothing in particular. Keeping them disabled and only unlocking when needed helps with Android's aggressive app suspending.

It's possible that as you use your phone, the apps themselves becomes slower, because it is managing more of your data.
A music app may work blazing fast when you've only got ten music in your library, but then you've collected about a hundred, and the database accesses becomes slightly slower as it's trying to generate the thumbnails or search through the ID3 tag indexes. The music recommendation engine may have worked blazingly fast when it only have to skim through half an hour of listening history, but then it got bogged down once or collected data the years worth of data about the music you skipped often and which ones you have been repeating over and over.
You may have taken pictures with camera app. Originally your gallery contains nothing, and the program can loop through the entire directory fast enough to not matter, but then as you snap more photos, getting a list of all files and looping through them all becomes a lot slower.
You may have added more people in your contacts in chat app. And the chat app have to work through a lot more of the chat history with more contacts and attachment files.
You've used the browsers, and browsers stores browsing history, bookmarks, etc. The size of a browser profile tend to go up over time.
These aren't necessarily solvable by a simple factory reset. If the app had online sync, they would have synced back these extra data that you didn't have back when life was simpler. Likewise with data stored in SD Card/external storage may not get wiped with a factory reset.

As in case of Alex.S' answer, I'm voting up yours, because it can be value to other readers, but I think, I won't accept it, since it is off-topic to my question. I clearly stated, that I did a full factory reset (so I assume, everything, that you're writing, that slows down my phone was cleared to the status of brand new phone) and this hasn't speed up my phone in any noticeable way.

Yes, a slightly lower\unstable voltage caused by worn battery can underpower the device SoC affecting performance and stability, not only the autonomy, in the same way can make a torch less bright.
I have observed this some years ago when replacing the battery of an old smartphone because of poor autonomy, I have seen also noticeable performance improvements. I have measured the battery output with multimeter and the battery related to poor performance had a lower voltage output (not only 700Mah reduced capacity at full charge compared to the new battery).
However there are also many others reasons that can affect performance, some Apps and services in the years after updates become more heavy in terms of memory(included built in Google services), or the storage nand flash memory can be worn.

Could be due to a couple of reasons:

Flash memory degradation. As you repeatedly write data to your storage, the hardware degrades and increases the chance of hardware failure.

New OS and app updates might not be optimized for your device, and use more resources.

Background processes. Some of the apps you install will open at startup and hog up CPU and RAM. Make sure you clear these.

Are you still dealing with a slow phone?
I'm making an app called Cycle (https://cyclephones.com)
It lets you stream an android emulator from a server to your phone so that you can run any app smoothly. It's great for gaming.
Would love to have you as an early tester if interested :)

CyanogenMod on Xperia Z1 compact: Amami or Yuga
I have in stalled CyanogenMod (CM) 12.1 on my Sony Xperia Z1 compact -- according to the CM website the name for that device is amami. The OS (Cyanogenmod version) that it runs, very much to my satisfaction, is 12.1-20150424-UNOFFICIAL-amami.
However, updates for amami that are downloaded, for installation in recovery mode, are refused because the ZIP installer (in recovery mode) says that my device needs a yuga update not an amami.
While the name yuga is reserved for Sony Xperia Z phones, which may be a generic class into which the Z1 compact also falls, I had expected that the amami updates, which are specifically for my device, would be a better fit.
Does anyone know how I can make the amami updates work on my amami phone with an amami ROM on it, instead of asking for yuga?

You are running an unofficial build/port of the rom. If You must use official N build of the CM rom you should first change to official CM rom.
 You can't simply jump from some xyz rom( that's what UNOFFICIAL rom is) to official CM Nightly(N) or stable (Milestone, M) rom.
 Also if you are happy with your current non-CM rom, you may continue using them. You have to get updates for it from the developer whose rom you are using. Check for updates at XDA-Dev or whatever other development site from where you got your rom.
 If you wipe and load official CM nightly for your 'amami' you will be able to receive and install updates from CM.

Makes sense I guess. But isn't it strange that it does first try to download the updates then in the 1st place?

It was an UNOFFICIAL ROM but iirc it was from the cyanogen web site.

@alle_meije Unofficial builds are by private donors and its their choice and responsibility whether they want to provide updates or not. That's why they are unofficial. CM puts many requirements and responsibilities on the shoulders of developers that may not be possible for the devs. Hence they use the CM source but don't want to go official.You can not download their rom from download.cyanogen.org.

Got it. For future peace of mind I'll just have to download + flash https://download.cyanogenmod.org/get/jenkins/126041/cm-12.1-20150915-NIGHTLY-amami.zip then. I must have downloaded the unofficial one when the official rom was not yet at v12. Thanks!

In the end it seems to be the TeamWin recovery manager app that I installed, which turned out only to accept yuga software. I could not even install the NIGHTLY from the Cyanogen site without flashing another recovery... Luckily that is solved, hope this post will help others.

Upgrading rooted Galaxy Note II
So after about 3 years I have finally received and Android 4.3 to my Galaxy Note II. It downloaded it but refused to upgrade (probably because my device is rooted).
What do I do now?
Can I upgrade it anyhow? (also would like have it rooted)

You will have to return your device to complete stock.  Since you have rooted it, in Settings - About Phone it will list your device as Modified, so if that's the case, you won't be able to update.  Going back to 100% stock in Settings it'll say Official, at that point, you'll be able to update.

Thank you, does that mean that I have to then root it again?

Yes you would have to.

Modern apps to manage app permissions
In doing research on app permissions and cool "l33t hax0r" apps to put on a rooted phone, I stumbled across a category of app permission managers.  They seem to be relevant to Android 1.x and 2.x, circa 2010.
The advent of Jelly Bean (Android 4.3) gave us a rudimentary app permission manager within Android, but not everyone got it, Google didn't mean to release it, and it was quickly removed from Android.
Is this category of apps no longer valid?  Or are there just a new bunch of apps and I'm finding stale posts, articles, and information?
I found this article here on Android Stack Exchange, and the answers link to most of the apps that I have come across (modified Google Permission Managers notwithstanding).
The only modern/supported app of similar design is a module for XPosed called  Xprivacy.  However, XPosed is only for Samsung ROMs/devices.  Is there something more generic?
I currently have some Samsung phones, and some of them are rooted, but not all the devices I am tinkering with are Samsung or rooted.

XPosed is not only for Samsung devices. Certain modules may be, but the framework is most certainly not.

Apart from that, there are much more permission managers available for Android. I've used LBE for a long time, XPrivacy certainly works on many more devices (I've used it on some), as does DonkeyGuard.

Donkey Guard works fine for me...It can manage Location,Identity,Media etc permissions as well as can use fake information for particular app (For e.g if for a particular app you dont want to share your no. than you can set some random no. via DonkeyGuard so when that app will try to access your no. it will get that fake no. not the orignal)

Three possibilities:

Try Advanced Permissions Manager found in the Play Store. But mind you, permissions are not granular. Example, if you deny Location right on an app and it needs some aspect of that right, then the app will not run.
Xposed's Xprivacy is very granular; I can disallow certain aspects of that same app's Location rights, for example. and the app will continue to work.
Xposed is not specific to Samsung; it's running on my rooted LG G3.

I would suggest the X-Plore file manager. It is a very handy tool once you get the hang of it. It has made all the file operations very easier. It uses a two pane user interface which makes working on it easier! You can find a full review of the app here.
You can also try the Advanced permission manager which relatively handles permissions better and does not require root.

Pop up about security problems

I had a lot of these pop ups and I don't know if it's for real or not.

Correct your date and time. Try if this solves your issue.

Based on the screenshot, what made you to conclude that the pop-up is related to virus or some other malware? Consider following the advice noted by @Manubhargav. You can also tap on View Certificate and show us the output of it. Anyhow, which website is it?

That note popped up and when I clicked it, it lead to a site that scanned my phone and said I had malware, that's why I posted it cause I just wanted to make sure.

First make sure your date is correct. Are you sure your date is correctly set and still getting this warning?

BTW: As @Firelord already indicated, the popup nowhere talks about a virus. I've corrected the title of your question accordingly.

It is worth saying that, based on what you've said, it sounds like some form of adware for an app.

Solution: Correct your date, or Set the clock to update automatically
Reason: This security warning pops-up when the verification of certificate needs to be done but the requesting system is set to wrong date(usually to the past).
The security certificate is seen as From Future.
This is all related to certificate validation by the browser.
Related Stack Exchange post
NB: This does not harm your phone (and certainly it's not a virus)
EDIT: There can be other reasons as suggested by @Lie Ryan - due to certificate mismatch / weak encryption / browser not trusting the CA

There are other possible reasons why you may get invalid TLS/SSL certificate warning other than expired certificate (or certificate issued to future date). The certificate may be issued for a different domain name than the server you're trying to connect to, or it may use a weak cryptography that are no longer trusted by the system, or it may be issued by a certificate authority that the browser doesn't trust. In any case, you may want to view the certificate and find out what's wrong with it. Or bail out to safety.

I didn't understand the reasoning for revision 4 and revision 5. Would you please care to explain a little?

@Firelord   I thought it was not necessary to mention about virus since the original question was edited removing the term virus for revision 4.  But then I thought it will help readers further to understand that android does not suffer from virus problems as many posts about virus have come up in the recent past, hence revision 5.

Image App which does not hide the directory structure
I sync images to the external SD cards of my android5 tablet.
I use this schema:
YYYY/MM/DD-event1
YYYY/MM/DD-event2

Example:
2015/09/01-morning-sunrise
2015/09/01-afternoon-shopping
...

All images viewers seem I tried seem to hide the underlying directory structure.
For me it feels like global evil forces trying to keep me stupid.
I can navigate trough the directory structure with the "My Files" app.
Opening a single image works with the gallery or photo app. But swiping to get to the next picture of the directory does not work :-(
How can I navigate the directory and view the images on my external SD card?

You've used the wrong apps then. My list of Image Viewers gives you a bunch of candidates, several of them supporting browsing per folder (e.g. QuickPic, F-Stop).

I suggest you edit the title. Title is asking for an app which is off-topic here. Body seems fine to me.

@Firelord the body is asking for an app, too. Why should l change the title?

Because questions asking us app suggestions/recommendations are off-topic here. See what on-topic in [help/on-topic].

@Firelord the body of the question is asking for an app. Unfortunately I have not enough reputations to close-vote my own question. Could you please do it? Thank you :-)

@guettli if you still didn't find what you're looking for, you can try SR. Also next time you're looking for an app, that's the place to go :)

I suggest you use the X-Plore file manager. It has the exact features of what you have expressed. The other file operations on it are also a lot easier and faster once you get the hang of it. You can read a review before installing from http://reviewlagoon.com/x-plore-file-manager-android/

I use Foto Finder now:
https://github.com/k3b/AndroFotoFinder
Up to now you can't install it via google play, only fdroid :-(

Can handle big image collections (15000+ images in 1000+ folders).
Uses Android's image content-provider. No initial image scan neccessary.
Find images via folder (with hirachical picker), wildcards that match folder/filename,

Just for the records: since the above app is missing some other features, I use F-Stop now.

What is actually happening when you hard brick a phone?
I've never hard bricked a phone. I've never seen one either. But hard bricking is everyone's worst nightmare.
I wan't to know what exactly happens when you hard brick your phone. What happens that makes it irrecoverable without professional help?
To find this out, I needed to know how flashing of ROMs work. For this, I downloaded the data sheet for my phone's chipset (an MTK6589, whose datasheet can be found here) and then found out that:

The USB data lines D+ and D- and VCC goes directly to the application processer.
There is an external PMIC for application processor that handles the power ON and OFF of the handset. On this IC there are two pins(KP_KOL0 and KP_ROM0) which when are 0, triggers USB download without battery.
The memory (eMMC or NAND Flash) to which the files are downloaded is also connected to the Processor via a External Memory Interface (EMI).

So this is what (I think) happens when you flash a wrong ROM:
Though I don't know what results in 0V on pins KP_KOL0 and KP_ROM0, but this happens when you want to download a new ROM, and the application processor switches/starts in Download mode.
I've googled what happens when you hard brick a phone. All I get are noob posts telling how or how not to hard brick your phone. Most of the posts say that when you flash the wrong ROM, the phone may get hard bricked. My question is,
What happens when you flash a wrong ROM that makes the phone hard bricked?
Or why does the processor become not responding at all when you hard brick it?

It has nothing to do with the processor, unless you've fried it.
Usually, the only software-based hard brick that is possible is when you overwrite the bootloader.  Without a (working) bootloader, the phone (a) cannot get to the point where it would load the operating system and/or (b) cannot have working software loaded onto it.
If you get into this state you need to access the hardware more directly to write a new bootloader, often using JTAG.

Or you could just backup your bootloader and then restore it using dd

@vishalbiswas Yeah, and how are you going to restore it with dd if the bootloader isn't working?

@vishalbiswas See Android Boot Process. (Source)

Most phones show up as a USB Device when their primary bootloader is gone but secondary is intact. You could restore it with a Linux machine to the correct partition.

@vishalbiswas I think OP intended "hard brick" to mean the recovery / secondary boot loader is not intact. http://forums.androidcentral.com/android-4-1-4-2-4-3-jelly-bean/303013-what-difference-between-hard-soft-brick.html

To expand on point (b). As there is no program loaded to communicate over a USB connection, you can never flash anything else using the resources on the phone. All "soft" methods require the phone's CPU to write to its own NAND, even when connected to a PC.

For it to be possible to hard brick a phone, some of the software that the phone has to run to boot and flash itself -- something from the point where it's a just-powered-on processor running address 0 to the point where the phone is writing a new image to flash -- needs to be itself in flash that the phone can write. Usually this is something like a secondary boot loader.   If you erase that, then you can't reflash anymore. Hard bricked.
On a phone where you can write something new with only the aid of whatever software is in ROM that the phone can't write, whether or not it's by shorting a couple of pins and there's USB straight into the processor, you can't truly "hard brick" the phone.  Unbricking would always be possible at least in theory, provided you can feed it the firmware in whatever format it needs.

I have more apps than my max storage

As you can see in the screen shot my device recognises I have ~.5 gig of storage left, but I have an impossible amount of apps. When I moved a 230 MB app from SD to phone the apps storage when from 5.18 GB to 5.15 GB. I was confused so am wondering if any of you Android Enthusiasts know what is going on, and how to solve this issue (assuming this is an issue)

what does it exactly mean to move data in phone storage and internal storage
I am using a Micromax canvas turbo
it has 16 GB internal memory
so when I install an app ,
i get the option to move the app to internal memory card ,
and then ican move it back to phon storage
so what exactly does these both mean ,
how should we decide ,
what app to move ,
or any info regarding this movement

"Phone storage" is essentially your /data partition, the main space on your phone allocated to apps.
"Internal storage" sometimes means the same but, since they are being contrasted here, it likely refers to the internal "SD card" partition.  Likely both of them are on the same flash chip, just set up differently.
SD cards (and "cards") are sometimes mounted later in the boot process, so sometimes it can confuse some launchers and you end up with app shortcuts being removed from your home screen.  Services also might not start properly.  Otherwise, however, they are more or less the same.  You really only need to move apps around if you're running out of space or if you want to be able to wipe one partition without losing as much data.

4 apps get installed after every reboot, how to remove them
I am using Micromax canvas turbo with Android 4.0 ICS.
I once tried to root my phone, but didn't find any good use so reverted it.
Now I have 4 apps:

Hola Luancher
One touch white
One touch Black
Lazy swipe

And I also have some internal app getting installed like:

TimeService
MusicProvider
backUpProvider

They all get installed and enabled after every reboot. How do I resolve this?

Factory Reset. Back up your data and perform a factory reset, and if that doesn't work, then you will need to root your phone to get rid of them. :|

i tried to root my phone , can you give any trusted rooting tutorial link ??

Another solution is to go to their app settings and disable them. It won't remove them from memory, but it will act like they are not there

I have tried disabling them , but they also get enabled after every reboot

Returned One M8 to stock but can't install OTAs
My UK EE One M8 was unlocked, rooted and running a custom ROM.  The CID is ORANG001.
I wanted to return it to stock so installed stock recovery and a stock ORANG001 nandroid, relocked the bootloader and returned to S-ON.

It all looks OK but when I start receivng the OTAs, I get this error.
We have determined that your phone may be running a modified version of it's system software.
What have I missed?

Are you sure there's been no modifications to the system partition? You should double check.

@keepcalm Sorry, that's a bit above my knowledge level.  How can I check?  What do I do if it is modified?  Cheers

Are you sure the nandroid you restored is completely stock (no leftover root or anything)? It's been a while since I used an HTC so I might be a bit rusty, but have you tried using a different Nandroid (maybe one of the ones here), or manually applying one of the OTAs in that thread?

Two errors that refuse to be resolved, Google Play, Android 2.2.1
I have an old phone (LG Optimus V) running Android 2.2.1. I recently took it out and would like to download some apps on it. It automatically updated Android Market to Google Play by itself, but for some reason, it wouldn't let me download anything at all.
I keep getting two errors:

Google Talk authentication failed
Error retrieving information from server. [RPC:S-7:AEC-0 4SL6-CLLI-5VT2I]

I have tried everything:

Clearing all data for Google Play and Google Services Framework
Uninstalling updates for Google Play
Restarting the phone
Resetting the phone to default factory settings
Creating a new Google account

I'm still getting the two errors above, and I can't download anything. Is there anything else I can try to resolve this problem?

If you are rooted, you could flash a gapps package. Sounds like you have a wrong version that updated to your LG

@HasH_BrowN That fixed it, although flashing the gapps package also installed a whole bunch of bloatware that slowed down my phone a lot. I've rooted it, so I went ahead and deleted Facebook and Twitter and other stuff I probably won't use in my lifetime.

you can also download the gapps package from http://www.teamandroiders.com/google-apps-gapps-for-android-roms/. Scroll down to Android 2.2.1, then click on which zip file you want. The tiny is only 7.9 mb.

Information pulled from
http://wikitechsolutions.com/1222/error-while-retrieving-information-from-server-rpc-s-3-aec-and-rpc-7-aec-0

Method 1: Level: Easy

First we have to remove our Google account settings on this device. Go to: Settings > Accounts > Google > Delete Account.
Then, we will: Settings> Applications > All> Downloads > delete data.
Settings> Applications > All> Play Store> delete data.
Settings> Apps > All> Google Services Framework > delete data.
We turn off the device. Turn it on again.
Settings> Accounts> Add Account

If not then try

Method 2

Please read carefully. If the download does not work from the device, you'll have to download it to your PC. Then copy it to the device, using the USB cable to a folder on the external memory (microSD).
The Facebook app is the one most commonly generating this error, so we will focus on that. If needed, changing app files can be applied to almost any application that is giving you this problem.
Facebook version 3.8 is what we want :
 Download Facebook 3.8 APK
How to get downloaded APK files to update through Google Play Store

Enable installation from Unknown Sources

Settings> Security> and check the box for Unknown Sources option

Locate the APK file you downloaded using a file manager.
Open and install the APK file.

If installed version is newer than the downloaded APK, uninstall it & reboot, then continue.

Open the application and login into Facebook with your username and password.
Close the application and reboot.
Open the Play Store & check for updates.
Remove the check from step # 1, for added security.

I had an old Motorola Droid that I was trying to use the same way, ran into same problem.  My phone is longer on the Verizon network, I think this was the source of the problems.
Tried lots of the stuff listed.  Here is what finally worked for me.  I suspect there may be a way to succeed without resetting your phone and loosing all of your installed apps/settings.

Reset the phone by going to
Settings -> Privacy -> Factory data reset (don't "Backup my data")
Here is where these instructions differ from everywhere else after a reset:

When the phone reboots, skip the activation step. (Because this phone can no longer be on the carrier's data or mobile phone network, as you probably have a newer phone using the same number, and if not, you still do not plan to activate it, this will be a Wi-Fi/bluetooth only phone)
When it wants you to register with an existing google/facebook etc. account or create a new account using google, decline.  We will come back to that.  This stupid thing has not bothered to get on a wi-fi network yet, how can it possibly link to an account?
Skip through the tutorial etc. until you get to the desktop screen.
Go into settings, and enable airplane mode.  This will prevent it from trying to use the mobile data network for any part of the account linkup.

Settings -> Wireless & network settings -> Airplane mode
(before you do that, you may want to disable Mobile Data) Settings -> Mobile network Settings -> Data enabled
Now you can attach the phone to a google account. When I succeeded,   I was using a google account I had created on the phone 10 minutes earlier before the last reset. (My phone wouldn't let me delete the original account without doing a factory reset.) I don't know if you can attach your phone to the original account you used when the phone was active, and have this method work.

I then went into Settings -> Accounts & sync settings
and disabled Auto-sync, and then added my new google account.
I then went to Market, and was able to download the app I wanted.  (Note that the original name for the Google App store was called Market, not Google Play.  If it offers to update to Google Play, I recommend not doing that, unless you have to to download a newer app.

BTW, I didn't record it, so I don't know what the phone's versions were before the original reset, its currently Android 2.2.3, Kernel 2.6.32.9-g68eef5 android-build@apa26#1 build number FRK76.  I rooted one of my old Droids, don't remember if this was that one.

Inputting math symbols in Android
I need to input calculus and trigonometric notations in Android.
How to input math symbols in Android?

I know this is an old question, but the answer might help if there are still people looking for what the OP asked.
There is MathKeyboard that comes loaded with math symbols from trigonometric symbols to logarithmic, integrals, subscripts, superscripts, etc.

From square roots to triple integrals, this keyboard helps you in math typing
MathKeyboard it's a keyboard that helps you with symbolic typing, for the ones who struggle to get a decent math text in common apps, this keyboard is fully compatible with all instant message services

When you open the keyboard, click on Menu to select symbols' categories.
The only caveat is that the free version contains ads.

Some replacement Android keyboards on Google Play deal with mathematical characters (I don't need many, so my keyboard is sufficient), and some mathematical apps provide a very broad range. See this Google Play query to see if any are a match to your requirements.

You can do this with your existing gboard.
Go to
Settings>language & input>gboard settings>languages>add Greek>save
Hope this helps.

Restore power button to default behaviour
I have LG G2 (D801) on Android 5.0.2 Lollipop, rooted. The power button stopped working. I am pretty sure an app messed up its behavior - I don't know which one of the many I recently un/installed trying to fix another issue. I am pretty sure it's not a hardware issue.
How could I restore its default behavior: press to optionally lock the screen and long press to bring up the power menu?

Not very helpful if you ask me. How do we even suspect what may be interfering with your power button if you don't even list those apps that you've tried and are still installed? Simply backup all of them and remove each of them. Restart and see whether the button functions normally.

Just go full stock with a factory flash. See if the problem is present then. If it is, it is a hardware issue, and you can claim warranty. If it works, be a lot more careful with your apps next time.

I thought of doing the same but figured I would post the question in case someone has a quicker/less brute force approach. If no one else comes up with that kind of answer, I will accept yours. Thanks

Contacts need restoration!
I see in my galaxy s6 edge that my contacts were saved on Sept. 9th. i then factory reset my phone and havent been able to restore the contact list. Everything else, messasges, phone records, and such are there, but not the names that go with the numbers. Ive tried google contacts under Gmail but that hasnt worked out. Any ideas?
thx,

If you didn't back up your contacts before you factory reset, they are gone. They will only be on google if you synced them to google. your phone will sync automatically if you allow with the settings for backup and restoring.

Play store does not list any installed apps
After installing CM11 and corresponding gapps I no longer see any installed apps listed in the Play Store. Is there any way to have them relisted without re-installing all the apps? I have tried clearing the Play Store data and cache.

Similar question: http://android.stackexchange.com/questions/115547/add-an-app-to-the-google-playstore-installed-list

This problem does not seem to be limited to Cyanogenmod devices. I experienced it on most new devices: Pre-installed apps are not recognized by Google Playstore.
The only way I found to make Google Playstore recognize that an app is installed is to search for the app in the Playstore. Usually the Playstore has an update for the pre-installed app and if you install this update manually the app will afterwards be listed as installed app in Google Playstore.

How to stream audio from PC to android device through USB?
How to stream audio from PC to Android Device over Bluetooth
Is there a way to stream all audio from PC to Android via USB?
Can I stream video from PC to an android device over USB?
I have found these questions, but since they're asked a few years ago, is it possible for now?
I've seen some new feature in android 5.0 and above, like this.
https://source.android.com/devices/audio/usb.html#androidSupport
But I don't know how to use those features to stream audio from pc to android device via USB, please help me!

What you just read from the Android developer's guide is actually a specification for an Android device to send, not receive, audio using USB to an external device, such as a charging dock-cum-music player. This is a host mode USB connection. This does not allow your pc to send ( stream) audio to your device via USB. However, if your PC has Bluetooth, maybe you can register your phone as a Bluetooth audio player and stream audio to it that way.

security implications of participating in app beta testing?
I am an IT professional (but not in app development). Two days ago  someone contacted me about a blog post I made and invited me to participate in beta testing for a messaging app which was related to my blog post. I have never before considered participating in beta testing for a mobile app before. For the android app, they are using Closed beta with Google+ community or Google Group.
At first, I was enthusiastic, but then I thought --- whoa! I don't know this person (or this company) from Adam. Although the developer's website looks legitimate, this person contacted ME, so this could all be a setup.
The instructions to download the beta app seem straightforward and seem similar to how legitimate apps do beta testing. And frankly, I doubt that this app has any malicious purpose. On the other hand, I have no reason to trust this app.
In fact, when I begin the steps for downloading the app and seei what privileges I am granting, I literally have no idea what the implications are.
So let me ask:

Are beta apps basically operating in a safe sandbox? Are there
significant differences in security risks between android and ios?
Generally is it easy to uninstall them?
When evaluating whether to install a beta app, is there an access
level which I should be careful not to grant?
Is there any sort of community rating system that might reassure me
that an app is more likely to be safe? I see all kinds of websites
which list apps for beta testers. Is there any reason to believe
that apps listed on these kinds of sites are vetted or determined to
be safe (or do not pose security risks)?
Are  certain kinds of apps  riskier to install as beta apps than others?
I assume that I should monitor performance (such as memory and storage use) when the app is running. Is there any metric I should be monitoring to ensure that the beta app is not dragging down overall performance?

Thanks for your help. Hopefully your answers can help other clueless potential beta testers like myself. I would love to participate in more beta-testing if I could be convinced that it would not pose a significant risk for me.
I have worked in software development before and even done a bit of testing on desktop apps  but I had VMs and understand the security model for Windows and Linux fairly well. But I only have one phone and 2 tablets (ios and android), and don't want to mess things up (though I regularly test ebook design on multiple platforms and displays).

Also consider that installing Beta apps often comes with an implicit agreement that your usages may be tracked more closely than with final release. The purpose of a Beta after all, is to collect feedback.

There is no real difference between a beta test application and a regular application for security purposes. You can remove any beta test application the same way you would a regular application. Android is setup so that applications do not normally have access to the data for other applications.
If a beta test is closed, then the Google+ or Google group is the access control for the beta test. This has no effect on the application on the phone.
If an application is in the Play Store, you have general assurances that it has been virus scanned. The Play Store is much safer than installing applications from generic websites. The Play Store will not, however, tell you anything about how the application works.
The permissions requested by the application determine how risky it is to use it. Permissions include things like:

camera
contacts
location coarse/fine
network access
read call log
read contacts
microphone

The general trouble is that applications ask for many permissions, and it is not possible to tell what an application is doing with those permissions. But if an application that turns your flash on and off is requesting access to your microphone or contacts, then you should get suspicious. If an application has access to your contacts and the network, then it is capable of sending all your contacts' information to a server on the Internet.

AFAIK apps don't even need the network permission to send data to the internet, just to use custom protocols to do so.

It isn't run in a safe sandbox mode, it runs the same way as other apps. You can uninstall the app or leave the beta test group if you want. iPhones are a bit more secure as they have to support less phones, but with Android and the right knowledge, you can make your phone very secure.
If it requires root permissions (only available if phone is rooted), then you should evaluate if it is safe to use or not as granting root permission is basically admin access. If it requires access to files or photos etc you should also check if you should install.
I do not know, but a general Google search can help here.
This is the same as Question #2. As some apps require access to more private stuff (like files), you'll need to evaluate it and see if the risks are worth taking.
Betas are used more to find out potential bugs, and to test new parts of the app, but you can monitor performance if you so desire.

General Way to join Beta Test
You'll join the Google+ Group, then access the beta join link, so that you can participate in the beta.
Once that has happens, you'll be able to download the update from the Google Play Store (may take a little while to show up).
And as such like any other app you have used before it will ask for permissions to install.

I don't know how it is in iOS, but there is no "install as beta app" in Android. All apps in Android are installed the same way - you install it or you don't. Once installed, a "beta" app would have the same rights and possibilities like any other "release" app. "Beta" has only lexical function here, not technical.

Device lose root access after installing SU .zip update from stock recovery
I rooted my device, Samsung Galaxy S3, by connecting my device to pc via usb, and one-click-root with KingROOT application(on my pc). It automatically install a superuser on my device, but it's not the SuperSU that developed by Chainfire, instead, it's called Kingo Superuser. It works fine, but unfortunately an app did not get authorize by Kingo Superuser, it keep asking for authorization from SuperSU.
I don't know why SuperSU is asking for update even though I just install it from Play Store. Since I don't have a custom ROM, I choose Normal when asking for update method. Before I do that, I already install the .zip update file from recovery. (I saw 3 red lines, ...can't get signature..., something like that when I install it.) After it completed, device starts to reboot. The worst thing is after rebooting, my device lose root access :(
I searched for solution online about updating SuperSU and related stuff but I can't find a clear solution. So I came here, how do I update SU binary in a proper way, without a custom ROM.
Thanks.

Use Rashr or Flashify app to write a custom Recovery on the device. After that installing or removing actual SuperSU is very easy. You just flash a file and that's it.

SuperSU zip is an unsigned zip and can only be flagged through a custom recovery like cwm our twrp. You can search on xda for a custom recovery for your device. Use Kingroot to root your device again, use fastboot or ODIN from PC (refer to XDA  for proper device-specific instructions) or Flashify to flash a custom recovery image, then full unroot from Kinguser, and then flash the SuperSu zip from custom recovery.

Comments are not for extended discussion; this conversation has been moved to chat.

"unfortunately the process com.google.process.gapps has stopped" even after hard reset
I have a Blu Life 8 (Kitkat) phone and was getting some annoyng messages: "com.google.process.gapps has stopped", i tried to hard reset it to see if the problem was gone, but even after reset i could not get the message to disappear, and now i can't even go after the initial setup process cause it crashes every 0.1 seconds showing this error.
Is there  way to fully restore the default settings or something like that? How can i solve this issue?

The best solution for your case is to fully flash your phone. I've been searching around for Android 4.4 firmware for your phone, but I couldn't find any, just for Android 4.2.2. But there is no problem flashing with it. Follow these steps and get your phone working again.
Flashing FW:

Unpack SP-FlashTool, and run Flash_tool.exe
Select MT6592_Android_scatter.txt from Firmware folder
Wait for file to be added into Flash Tool
Choose Option -> USB Model, click USB Model
Choose Option -> DA DownLoad All->Speed -> High Speed, click High Speed
Turn off your phone, remove the battery then put it back after few seconds (and don't turn on the phone).
"Press F9 (hit Download button)" OR "if upgrade ROM Firmware->Upgrade "
Connect your phone into the computer via USB data cable.
The process will start and a red progress bar will appear after color purple, yellow.
And green circles display

Finish!

Transfereing Apps on Samsung
I had some apps which were very useful on my old Samsung S3 and wanted to transfer them to my new s3. I went to applications manager and clicked on move to sd card. Not all the apps.can do this? Also now the sd card is in my new s3 I don't know how to access or install the apps that are supposed to be on my sd card.
Any help or ideas with this?
Thank you

You can't transfer apps like that. app2sd only moves parts of the apps to free some "internal storage" – and no, not all apps support this (if they offer widgets or run services, they cannot be moved this way).
So as you never get the full .apk file moved-over this way, it obviously doesn't work for your purpose. What are your alternatives?

You can install them from Playstore (or some other market place)
You can restore them from a backup taken
You can use some "APK Catcher" (see my list of apps to Backup your apps for possible candidates)

Note however that if you want to transfer the apps' data along, you either need root – or have to use adb backup (see our adb tag-wiki for a starter).

Google Play Services Has stopped message continually popping up on my Samsung phone
The following message keeps appearing on my Samsung Galaxy S4 phone screen about every three seconds
"Unfortunately, Google Play Services has stopped".
Is it actually a virus or it is a problem with the Google Play Service?  I have tried disabling the Google Play Service but the message keeps appearing.  I have Norton Mobile running on my phone to pick up on viruses and to alert me to any possible security issues and also Lookout. They haven't picked up anything.  Does anyone have any suggestions?

Did Norton ever report a virus to you? If so, it's time to drop it: there are no viruses on Android (malware yes, but no viruses). Try uninstalling the updates to Play Services, that often helps in such cases (sometimes updates have trouble; they get reinstalled after you removed them, and that time maybe cleaner, so don't worry about that).

No Norton didn't report a virus to me.

I doubt it ever will, for the given reasons. Anti-virus apps are discussed controversely – they often cause more issues than they solve. Don't ever rely on them alone. They have their "uses", granted – but never more than a piece of a whole concept. // But back to your issue: Have you tried uninstalling updates? Did that help? As I wrote (and you can find that for many Google-app issues listed e.g. in our google-play-store tag-wiki), this is often recommended as possible solution.

This helped me: Settings - Accounts - Google, remove the account and add it again.

Solution 1 – Update Google Play Services to the latest version. You can download from here. You may be getting an error because you have a very outdated version or the one you have is having a conflict/bug with the current Android version in your phone.

(source: teamandroid.com)
Solution 2 – Clear the Google Play Services cache. The Google Play Services app in your phone acts like a framework for all the Google and Google Play apps installed in your phone. You can try cleaning up its cache and see if that would fix the issue. This worked with one of our team members! Read these quick and easy steps:
Go to Settings > Apps.
Scroll to All apps and then scroll down to “Google Play Services” app.
Open the app details and tap on the “Force stop” (see "Force stop is disabled" below) button.
Then, tap on the “Clear cache” button.
Solution 3 - Uninstall the updates of "Google Play Services".
As in solution 2, go to Settings > Apps.
Scroll to All apps and then scroll down to the “Google Play Services” app.
Open the app details and:

Tap on the “Force stop” (see "Force stop is disabled" below) button
Tap on the "Disable" button
Tap on the three dots at the top right and select: "Uninstall updates"
Once the uninstallation is completed, tap on the "Enable" button

Solution 4 – Clear the Google Services Framework cache. The Google Services Framework system app on your Android device stores information and helps your phone sync with Google servers — and keeps your Google Play Services up and running. This could be one of the reasons why you are not able to connect to Google servers using the app and keep getting the error message. Read these quick and easy steps:
Go to Settings > Apps.
Scroll to All apps and then scroll down to “Google Services Framework” app.
Open the app details and tap on the “Force stop” button.
Then, tap on the “Clear cache” button.
Solution 5 – Check your Internet connection. Maybe your WiFi network is blocking any of the IP addresses that Google uses. You can also try switching the WiFi on or off on your phone — same with mobile data.
Solution 6 – This goes without saying, but maybe a simple reboot of your Android phone/tablet could fix the problem.
Solution 7 – I hate to say this, but in the end, you might just want to install a custom ROM that is stable with no bugs.

Force stop is disabled If either the "Disable" or the "Force Stop" buttons are disabled then:

Go to Settings → Device admin apps
Deactivate the following apps if they are listed:

Find My Device
Google Play

(example on Android 8.0.0, Samsung Experience 9.0.0)

Note: Please, keep in mind that you may have to experiment with what apps you deactivate.
Your device admin apps list may differ. For example, you may have more or entirely different apps.
I have found that disabling the above two apps was enough for me to disable and force stop "Google Play services".

I'm not sure which version to download

Ashrith, Play Services auto-update themselves. No need to download some experimental "new version" – especially not if you already have issues with the one installed, and especially not from a place where you can't tell if it's safe. Clearing cache is a good point I've missed in my comment on the question itself, however.

I fixed this issue by clearing the Data for Google Play Services, rather than just the Cache as mentioned in this answer.

I updated to the latest (public, official) versions of the OS and Play Services using the Samsung Smart Switch software, connecting from my laptop to the phone via USB. See method 4 at this link: http://www.geeksquad.co.uk/articles/how-to-factory-reset-your-samsung-galaxy-a3-2016

I had this problem due to a conflict between my custom ROM (Katkiss) and the latest versions of Google Play Services.  The solution was to revert to the factory version of Play Services, install the last version known to work with the ROM, then create some folders to prevent Play Services auto-updating to a bad version.  I used these instructions for the detail: https://forum.xda-developers.com/eee-pad-transformer/general/how-to-fix-crashing-google-play-services-t3557521  The same should work with other ROMs/devices, but you'll need to work out which version of Play Services you need.

@DavidWaters
All of this application's data will be deleted permanently. This includes all files, settings, accounts, databases etc. I did them all and it didn't work. I'm trying to delete data, but I get the above message. I'm wondering would it delete my WhatsApp, Telegram message or it won't have any affect?

Find My Device is buried under Settings → Biometrics and security → Other security settings → Device admin apps → Find My Device, at least on my phone.

I my case, the problematic device was running Google Family Link and it was the phone of a child. In this case, Family Link app is device admin and cannot be disabled without resetting data. I had to factory reset the phone to fix crashing.

Here is the way to fix this issue: go to APKMirror, find the last Google Play service, then download and install it. That's it. If you are having any problem then just go to the Settings → Applications → All → Google Play Store → then Uninstall Updates.

I've experienced this problem also and I found out the cause of it.
So when you access any Google stuff the Google Play Services are used right.
Okay, that means that each time you play around any app using those services, it s going to require your device to be awake and/or keep the device awake.
For some time I have used the Privacy Guard to make a restriction for this behavior i.e. to stop the apps from keeping my phone awake, even though it's locked/asleep.
So I went to the Privacy Guard and set the setting to "Ask every time" and what do you know, it started popping like crazy.
In conclusion: when you need to use the Google Play Services - set the permission for it to "Allowed", if you don't need it - that's when you want to stop it from draining your battery like crazy, then set it to "Denied".

Would be useful to actually explain the steps you take, or maybe the fact that you are referring to a third party app...

After some searching, I found this solution from Google Play Help (archived) and that's how I solved the problem.

Go to Settings -> Lock screen and security -> Other security settings -> Device Administrators (in your version it may vary slightly)
Uncheck "Find My Device"
Go to Settings -> Apps -> Google Play Services
Tap the vertical ellipsis (3 vertical dots) at the top right -> Uninstall updates
Go to Settings -> Apps -> Google Play
Tap the vertical ellipsis (3 vertical dots) at the top right -> Uninstall updates
Restart phone

At this point, the message  "Google Play services keeps stopping" was gone. You may try now to still do

Open one of the Google apps (in my case Google Maps)
It complains that "Google Play services" is outdated, click the popup to update it again.

This is the only recipe that worked for me. Switching off "Find my device" was key.

The problem is in the updates. I fixed this problem by uninstalling updates from the Google Play Services app. All my Google apps started working. I went back in and reinstalled the update and it stopped working again so that tells me it's in the update.
Go to Settings - Apps - Google Play Services.  Do a force stop on the app, and clear cache and data. Check and see if your Google apps are working. If you reinstall the update, it may stop working again.

This worked for me! I have no idea why this has been downvoted!

I've been having wakelock issues for the past week (OnePlus One) and today narrowed it down to googleplayservices. After some searching and reading, I went into Privacy Guard and turned permissions off for "Wake up" and "Keep Awake". My handset was again able to go to sleep after the set 15 seconds, but then that "Unfortunately, Google Play Services has stopped" error started popping up every 3 seconds in an endless loop.
I didn't connect the dots until this thread (hours later). Turned each back on separately to confirm. It's the "keep awake" that was the culpit. They're both on again, and I assume my phone will again have insomnia until whatever is wrong with the last update gets fixed.
I assume that googleplayservices needs to keep checking for something and preventing it from keeping the phone awake was causing the error loop. Maddening, but I can say from experience that that looping error is far worse than having to manually turn off the screen!

Is it possible to install android wear apps on android smartphone?
I'm an Android developer and recently I've started to develop apps to Android Wear. The problem is that I don't have an Android watch and the emulator is too slow.
Does someone knows if there is a way to install Android Wear apps on an android smartphone or install the android wear os on android smartphone

I think till now there is no such way to test Android wear app in mobiles.

I use the Android Studio in-built emulator and there is no lag whatsoever, try configuring the VM to maxed out settings.

What is "Assistant 1.0" app and how do I get rid of it?
I have MetroPCS and a ZTE ZMAX Z970 phone with Android 4.4.4
This app appeared, I don't know exactly when, and it's got some worrisome permissions and I want it off my phone, but it has no uninstall option and there's nothing on Google Web Search about it.
It looks goofy enough to be malware.
(Click image to enlarge)

Is the device rooted? If not, then you can't install that app easily. If your device has never been rooted then assume that your OEM has shipped that app in the device. Also, give us its package name. Install [tag:adb] and give us the output of pm list packages -f -s | grep "Assistant".

ZTE ships with a smartphone management tool name Mi-assistant. Could this be that? Google ID: com.zte.heartyservice

Keep in mind that uninstalling this app could eliminate some core feature of your device.

@DanHenderson, thanks for the warning. I would have to root it to uninstall it, and I don't think this phone can be rooted.

@Firelord, it's not rooted. I don't think this model can be. I'll run pm list packages and let you know. Thanks!

@Manubhargav, I don't think so. The icon is not the same and my app can't be ran or interacted with. https://play.google.com/store/apps/details?id=com.zte.heartyservice

Giving the package name would help as @Firelord suggested. Also if you're not comfortable with adb,  you can install System Info for android and see package name.

@Manubhargav, thank you I will install that. Signal too bad at the moment, but I'll check it when the icon hits my android desktop.

Headphone icon won't go away
A headphone icon popped up on my LG G3 phone yesterday.  It won't let me hear phone calls if I call or receive them.  It also won't let me play music.  The only way I can hear anything is if I plug the headphones in.
I've tried cleaning out the headphone jack, making sure the hearing aid impairment was off, and I even reset my phone.  Nothing has worked and I
still have the problem.
What can I do to fix this?

It sounds like hardware issue, try pluging in and out headphones maybe it will fix itself.

try rebooting the device

I simply insert a needle inside the audio jack to short-circuit it. It works and the headset icon disappeared.

I think the headphone jack is shorted, and it needs to be cleaned or replaced by a new one. Unfortunately, both need to disassemble the phone. Here is a short YouTube video for how to replace the jack.

This just happened to me as well. Took a Q-Tip with rubbing alcohol and cleaned it out but didn't work. Took an air duster and blew it up there and it's now gone.

This is a common problem on Redmi Note 4 (I have it too right now :D). Headphone jack is damaged and thinks there is a headphone plugged in permanently which results in android never playing sound over the speakers. For phone calls you can turn on the big speaker so atleast you still can hear callers.
The only way to fix the issue is to completely remove the jack (and replace it).

What happens if I remove my dropbox account from my phone so I can add another account?
I want to add another account but I have to remove the other one first. Will that delete all my photos? Or can I still access my photos if I log in on my dropbox account online?

Logging out will not delete your photos or other content. You will still be able to access all content in the old account via re-logging in on that device, another device, or in browser.
However if you have multiple accounts, you may want to be sure that you are using each account in accordance with the terms and conditions of service of Dropbox.

How do I see if my Android Nexus received the latest security updates?
I'd like to check the patch level of my Nexus. I'm using Lollipop 5.1.1 build LMY48I. Under 'System updates' in 'About phone', it says 'Your system is up to date'. Should I assume that includes security updates?

In Marshmallow (Android 6.0) there will be an additional bit of information on the 'About' screen showing the "Android security patch level". This should show the date of the last security update that your phone has. How you will know that this is the latest available is unclear though.
Source
As for pre-Marshmallow the best suggestion I have is to look at the factory images page and see what the latest build number is for your device. Depending on which device you have there should be a newer version than LMY48I, most likely build LMY48M.

The Build number, e.g. LMY48I (found in 'About phone') can be looked up in the Android Security Updates list, or the list of Android factory images.
In this case you can see LMY48I refers to the August 2015 security update, but there has been another update since then: LMY48M for September.

If you mean the Android Device Protection (ADP), then according to Google,

applies only to devices running Android 5.1 or higher that came
  preinstalled with Android 5.0 or higher, such as Nexus 6 and Nexus 9.

References ..here and here.

No, not for the anti-theft. Google started pushing out monthly security updates this year.

My bad, according to Google, this update was made to patch the Stagefright exploit, and if you want to check if your device vulnerable or not, then you can use one of this apps, 1. Stagefright Detector ( https://play.google.com/store/apps/details?id=com.zimperium.stagefrightdetector ), 2. Stagefright Detector ( https://play.google.com/store/apps/details?id=com.lookout.stagefrightdetector&hl=de ), everything you need to know about Stagefright in this article ( https://www.androidpit.com/what-is-stagefright-on-android-am-i-affected-and-what-can-i-do ).

Cheers. I was hoping for an easier way to check for future security updates as well.

Samsung S4 Google Sync Settings Problems
When I am in settings, Accounts, Google, myemail@gmail.com, I see "Sync turned off. I select it and get a list of things I can sync. I can hit each and sync it, but there are no check boxes to auto sync certain features, I have limited data and don't want to sync all continuously, not that I can see how to anyway. A few minutes ago, at the bottom I could choose 'Sync All', now that option is gone, this whole screen makes no sense to me, basically, I always want to sync contacts, gmail and Chrome settings, nothing else, anyone know how? Always in awe of how bad menu designs/UIs (don't) work.
Thanks much!

I am using S4 Kitkat though, however I was in the same situation where I needed to enable Sync for selective Providers like Google mail, Calendar, Contacts (not Google Games, Google Books etc).
I ended up using the Synker App (Paid) to achieve those. However, not sure if it works equally well in Lollipop!

Samsung Galaxy J1 will not play music from my SD card
I have purchased a Samsung Galaxy J1 and it will not read any of my music from my SD card. My photos show up but no music. SD card worked okay in the last phone.
I have tried to download music players and MP3 conversions but nothing works. Staff at Spark said that they have no idea what to do.
Please help.

Create a folder named Music in your SD Card and move all songs to that folder. Try if that works

In my case I had disabled the Google Play Music app, so no music was playable; neither from the SD card nor from internal storage. Not exactly the same issue, but just in case someone else hits this :)

Copy the songs to your SD card, while connecting your mobile to the PC and try to play these songs. Also try using TTPod music player as the inbuilt Samsung music player won't support the different formats.

Thanks already tried this and it did not work. thanks anyway

I had the same problem and it turned out to be the file format of my music which is not supported on the Samsung Galaxy J1.
I installed the PowerAmp app from the Play Store and I can now play my music. PowerAmp plays just about every type of music file. There is a trial version which lasts two weeks so you can test to see if it works for you. The full version costs £2.99 when you are satisfied that it works, and want to buy the full app.

Difference between Google Photos Sync and Google Photos Backup Sync?
In the Accounts section of setup, what is the difference between
Google Photos Sync and
Google Photos Backup Sync?
When would I want to enable one over the other, and when would I want to enable both?
Specs:
Moto G 4G, 3rd generation, UK edition
Android 5.1 Lollipop

Did you see this thread: what is google photo sync under account>google?

Then there is also this article which kind of make things a bit more clear: Yes, Google Photos Can Still Sync Your Photos After You Delete The App and this brief tutorial on what is Google Photos Backup Sync. This XDA thread also helps: Does Google Photos Backup Even When Uninstalled?.

Google Photos in sync is what synchronizes your photos saved in Google Photos with the device. So if you add a photo on one device, it automatically appears on your other devices. This is only going to use data when photos are added/removed from Google Photos, so it shouldn't really be a concern for the battery unless you're constantly uploading photos to Google Photos from other devices or the computer.
Google Photos Backup is the automatic photo backup feature that uploads your pictures/videos to Google photos automatically. You can disable this, but you have to go into the Google Settings app. In there go to Google Photo Backup and you can turn it off or set it to upload only on wifi or mobile as well, and you can even set it to run the backup only when charging. And this will only be contributing to battery usage while photos are being uploaded, so unless you are taking tons of photos and have them set to upload over mobile or wifi.
Now the decision is yours!

How to copy the phone number of the sender of a text message?
I'm using a service to report SMS spam via text messages. First step is to forward the text message, and the second step is to send a text message containing the phone number of the spammer.
I achieve the first step by doing a long press on the message itself, then I have a forward menu.
But I can't find a reasonable way to do the second step.
I can see the phone number in various places, but never in a selectable text field. So I have to create a new contact for the spammer, give him a name, tap the phone number  text field, copy, and go back a few steps to create a new text message, then paste the previously copied phone number.
Is there a faster way to do this ?

The message itself reacts to a long press, but the contact bubble on its left reacts to a single tap. Then you can long press on the phone number in the bottom field, and you can copy the phone number from there.
Edit:
There has been a change in in Android 6.
This answer does not work with the new message application.
With Messengers (as opposed to Hangouts, you can't copy the phone number by tapping the bubble icon.
Instead, tap the three dots in the top right, then find Participants et options (not sure what it is called in english), long press the bubble the label or the bubble of the person you want to copy the phone number from, then copy.
Unfortunately, the actual copy operation behind the menu doesn't seem to be implemented. The phone number is not copied using this operation..
This is inconsistent with the previous way, but it makes more sense in a way, if it worked.

Press the three dots top right. Choose 'Add Reciptent'. Phone No. appears in a box with a red minus sign to the right. Tap on the number. Choose 'Edit' from the box that appears. Long press on the phine number. Select 'Copy' from the menu which appears (3rd right). Open a new text message. Press inside the message box. 'Paste' appears. Selecting it - Bingo!!!

As an alternative, you should be able to automate this process very easily via Tasker. You can configure certain qualities of a spam message and have Tasker automatically forward it, or you could 'tag' the message somehow (reply with a certain string possibly) and have Tasker detect the tag and forward the corresponding message.

On Samsung phones (tested with a Samsung Galaxy Note10+), with the Messages application:

Tap on the number.
Tap on the (i) icon that has just appeared.
On this new screen, long-press on the number.
In the menu that appears, choose "Copy".

Unfortunately, it is currently not possible to long-press on the number at an earlier step.

How to set signal strength threshold for switching WiFi on and off?

When the WiFi signal strength is low, the phone switches to a 4G
network.
When the WiFi signal strength is high, the phone switches to that WiFi
network.

This is normal behavior for any Android device and all too familiar to Android users, or to users of any WiFi enabled device in fact. But the problem I often run into is that the WiFi signal is too low to be usable, and too high to switch to 4G automatically.

WiFi signal strength 0 < x < 0.5 marks (bars), the phone switches to
a 4G network.
WiFi signal strength x > 0.5 marks, the phone switches to that
WiFi network.

These values are not real measurements. They are merely my own perceived points at which the phone switches between the two.
TL;DR:
Is there a way for me to optimize the auto-switching between WiFi and 4G to my own liking? Is it possible to set that threshold point manually? What I would like is to switch over to 4G as soon as the WiFi signal is below the 2 mark point.

What I am often forced to do, in order to get (usable) Internet access, is to enter the Settings menu on the phone and disable WiFi altogether in order to force my "smart" phone to switch over to 4G!
Would it not be better if the user could control the threshold at which the phone switches between WiFi and 4G? I think the default threshold is too conservative. It's set up to conserve 4G bandwidth by free-riding on available WiFi networks for as long as possible and whenever possible (available).
Devices are optimize to make use of WiFi as much as possible, due to associated data costs on 4G networks. But this is a nuisance! My Internet access is almost completely crippled for many of the WiFi networks I have access to, whenever the signal strength is below the 2 mark point. On the other hand, I have over 4 GB unused bandwidth on my carrier network, for which I have a much stronger signal, but I have to disable WiFi first in order to connect to 4G. That's not convenient when you're on the move a lot.
I have recently started using the 4G network almost exclusively. I have stopped using WiFi because I have had enough with enabling and disabling it back and forth, and having to remember to do it when I'm on the move. So I am looking for a more permanent solution to this.

@sammyg you can take a look at my answer here for a starter. Might need some adjustment, though :)

in the same vein, though little different, but it seems like you can set a threshold:
https://android.gadgethacks.com/how-to/make-your-android-automatically-switch-strongest-wifi-network-0172651/

This would be messy for a comment, so consider it a partial answer.
The following task can stop or disconnect a WiFi if the signal level is below your preferred level.

Create a task named "Wifi" and create following actions in it:

Code → Run Shell:

Command → echo "%WIFII" | awk '/Sig: [0-9]/ {print $2}'
Store Output In → %Signal

Alternatively, since awk requires installation of Busybox, for non-rooted devices use the action Variable → Variable Search  to search the integer next to Sig: in the variable %WIFII and save it in %Signal.
Task → If:

%Signal Maths: Less Than INT

Replace INT with the signal value (0-9) at which Wi-Fi should disconnect
Net → WiFi → Off | Net → WiFi Net  → Disconnect

It is up to you how you want to use this Task.
Note: Tasker has a profile option "WiFi near" under "State" where you can select SSID and/or Signal level of WiFi in proximity.
Hint: You may try running that task with a bit more modification under an infinite loop.

No, there simply isn't something like this. Maybe someone has made an app for this, but this function isn't to be found in An

An app solution would be acceptable too. It doesn't have to be implemented in the system.

Symlnk failed in strange way on Samsung Galaxy S3
I tried to create a symlink for the external SD on a Galaxy S3 as I have done it on my HTC M8 previously. I tried with terminal emulator in command line, with Root Explorer and with Solid Explorer. It always worked and they were fully operational – but when I rebooted the device they are always lost, no track of the symlink previously created. Could someone explain, what is happening and how to correct that ? Thank you.
I forgot, my device is GT-9300 French running Android 4.3

Very much depends on where you wanted to create the symlink. A good guess: in the root FS? That would explain, as that FS is built up from a RAM disk on boot. You'd need to either manipulate the boot-image then – or use some init.d script to create the symlink on each boot. Doing it with an app like Tasker would be another approach.

@Izzy, that is a valid answer. Please make it one.

@TamoghnaChowdhury Yes, sir – done so, with a few more details making it a valid and detailed answer :) Thanks for the heads-up!

Thanks for idea. I have it done with init.d after implementing on my stock ROM. I also did with Tasker. Both worked very well. I prefer init;d as it is a system solution.

That very much depends on where you wanted to create the symlink. A good guess: in the root file-system? That would explain the behaviour:
Android uses an initial RAM-disk (aka "boot-image") on startup, from which it creates the rootFS (and several other things) anew each time – so changes to the root file-system don't survive a boot. That leaves you with at least two or three options:

manipulate the boot-image: only if you have the experience. Getting that wrong, and you might have to flash a fresh ROM (worst case; keeping the original, you could replace it via recovery-mode – but the try-and-err process might take a while)
use some init.d script to create the symlink on each boot: Requires your device/ROM to support the init.d system (not all do). Again, a "borked script" might screw your boot process; but you could verify your script (running it manually) before placing it into init.d, and doing so keeps the risk level very low.
Using an app-based solution: apps like tasker offer to run stuff as soon as boot is completed.

Distinguish samename apps installed?
I sometimes installed apps with the same name. Checking their info doesn't help me distinguish between them,because i think the only way is to find out the authors, and app info doesn't provide that. How can we distinguish samename apps installed? Can we fi d out their authors? Thanks!

How would you like to distinguish between them? I mean, is there a goal attached that I'm unable to see? E.g. in Lollipop, you can see package name (always distinguished) of apps in Settings -> Apps. In some custom launchers you can rename the apps. Besides, icons are usually enough to distinguish sometimes. See if App Browser helps.

E.g., i have two apps called Messaging. One, only after i open it to find out, is from Freedompop, while i can't find out about the other

Get rid of TouchWiz

No better options? Can I just uninstall it somehow? Can I found somewhere completely clean Android?

No, you can't uninstall it – it's too deeply integrated with the system. Only options are alternative launchers, or alternative ROMs.
