Problem #1: Galaxy S6 won’t power off or restart | Galaxy S6 overheating after lockscreen becomes unresponsive and camera turned on by itself

Hi. I have a Samsung Galaxy S6 which is 17 months old. My phone has been behaving as per usual until tonight. I put it on charge whilst switched on and then 5 minutes later went to unlock the screen. The screen displayed my lock screen picture but then suddenly the buttons and screen were unresponsive. The phone then reset itself and the Samsung logo was displayed. Instead of then loading up with the security code screen, the camera turned itself on. Yet it would not let me take a picture and none of the buttons worked or screen. Then a blue screen flashed on screen twice and after a blank screen for a while and then the Samsung logo (as if it had reset again). I have tried to power off with no luck and also reset with no luck. It seems that all buttons are failing to work and the phone is getting quite hot. please help! — Mark

Solution: Hi Mark. In the least, this issue may be caused by an unknown software glitch, while at the most, the device may have suffered a fatal hardware malfunction. There’s no way to know what’s going on for sure.

The first thing you want to do is check if you can boot the phone to other modes. If you can’t, then the most logical thing to do is wait until the battery is fully drained so you can charge it again. Below are the steps on how to boot the phone in other modes:

Boot in Recovery mode

  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode

  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode

  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

If the phone remains unresponsive after draining the battery and charging it, call Samsung or your carrier for repair or replacement.

Problem #2: Galaxy S6 won’t load beyond Samsung splash screen

I have a new 2 month old Samsung Galaxy S6. It has been fine up to now but last night immediately after hanging up on a Skype call the phone tetradoxinent black and then displayed start off page (image that come up when you switch the phone on). Then it froze like this. I know it only had about 15% battery left so i ignored it during the night and imagined it would run out of battery. This morning i woke up and the phone was off. I charged up the battery and tried to switch it on with no success.

After checking on the internet i learned about the ‘power button + volume down button’ and it switched on but is now frozen once again on the Samsung starting page. I have tried to reboot several times using the same 2 buttons and always restarts but stays frozen on that page. I’m currently travelling abroad for another 2 and a half months in Asia so i can’t take it to the shop where i bought it from.

Also, when you ask for the android version my phone uses, i have selected the first option because it is compulsory, however i don’t actually know what Android version my phone uses. Any good advice? Thanks in advance. — Alhena105

Solution: Hi Alhena105. If the phone no longer boots normally, there’s very little to nothing that you can do about it. Try booting the phone in other modes, like what we suggest to Mark above and see if you can force the phone to work normally. If not, try booting again in download mode and see if you can flash a stock firmware. This procedure requires a good guide and correct firmware so make sure you find a good reference online. Use Google to look for a guide on how to do it.

Problem #3: Video keeps on showing up on Galaxy S6

On my Galaxy phone I have a random video that pops up about every few hours. Does not matter which app I am in. Sometimes while I am texting and it has happened on the home screen without even an app being touched. It has a X in the upper right corner so I can end it. The phone has never been rooted and I only go to Google Play for my apps. So I am thinking it must be from a webpage I visited. I have tried clearing cache. I have uninstalled apps that were put on since I noticed the issue. So far no change. I have Lookout for an antivirus and since this issue started I have installed Adguard & Addons Detector. But nothing has worked. I am coming pretty quick to a factory reset as being my last option. — Jake

Solution: Hi Jake. If the video that keeps popping out are ads, then your phone may be infected with an adware. Do a factory reset, observe the phone for a few days and make sure that you don’t install anything during this time. If the issue won’t happen during the observation period, then one of your apps must be to blame.

For reference, these are the steps on how to factory reset your S6:

  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #4: Galaxy S6 keeps showing “sorry system UI not responding” after installing Verizon update

I install Verizon security update like it told me to and the install did not install correctly I guess. Now every time I turn my phone on it says “sorry system UI not responding.” I have tried everything, safe mode, clear cache, put it in easy mode, put it in ultra saving mode. All I need from the phone is some pictures. I have not tried a full reset yet due to this problem. I am stuck in ultra power saving mode now and my computer can’t connect to my phone since its in ultra power mode. Any help getting it out of ultra mode? Everytime I click off for ultra mode it says “sorry system ui not working” and the phone resets. Same when I go to photos to sync, it just restarts before doing anything I need. Any help would be amazing, thank you!!!!!! — Chris

Solution: Hi Chris. We know where you’re coming from but unfortunately, factory reset is just as necessary as wiping the cache partition. There’s just nothing else that you can try to get the phone back in working order other than this procedure. Obviously, doing so will delete everything off the phone’s memory but it’s either that or letting your phone become an expensive paperweight.

Problem #5: Galaxy S6 cannot send SMS in Google Hangouts app

Cannot send SMS texts via 3rd party apps. I can receive all texts, cannot send SMS texts through Hangouts or Google Messages. however I can send MMS through these apps with no issues. It started with my old S6 Edge and I got a replacement due to another issue but the problem remains. I have done a hard reset and a full data wipe to factory settings and still not working. It will just sit on ‘sending’ for a few minutes and then give ‘sending failed, tap to retry’ message. Samsung and AT&T are unhelpful as they said that Hangouts is a 3rd part app. Don’t agree since it comes preloaded on my phone from the factory, but still no use. Worked up until two weeks ago and I did not change any settings or download any new apps at the time it stopped working. — Jahn

Solution: Hi Jahn. We don’t work for Google so we are not aware how their products work in the background, specifically on how Hangouts sends and receives SMS. We think third party messaging apps like Hangouts continue to use the registered message center number on the device. That means that if you’re having issue sending SMS via third party apps, it should be replicated on the first party messaging app as well. So our question is, are you having an issue sending SMS via first party messaging app too? If you are, then make sure that the message center number is set correctly. If you don’t have the right number, contact your carrier and ask for it.

On the other hand, if the correct message number is already in place and you have no issue sending SMS via the primary messaging app, we suggest that you contact Google and ask them for support.

Problem #6: Galaxy S6 damaged by water stuck in safe mode

I have unfortunately dropped my Galaxy S6 in water and damaged it. At least 2 of the three water damage stickers are showing damage (2 red ones). Everything seems fairly well functional despite this except my charging is screwy but I’m confident I know how to fix that, which leads us to the real issue. The phone is now stuck in safe mode. I had this problem once before, except no water involved, but I have 2 S6s.

So, I swapped the bent button for the good one but this time the button isn’t bent. I even completely removed the button and still safe mode. I tried booting using the power+ volume up method (didn’t work) AND home+ power+ volume up and down which took me to a warning about custom os installation. I was unable to choose either option.

While on and in safe mode the volume up works perfectly but volume down doesn’t work at all though in call volume decreases on its own. Also it has magically come on and NOT be in safe (2 out of 100 tries) but the phone is also cutting itself off randomly and that kicks it back into safe mode.

I plan to clean the logic board with isopropyl tonight and see what that does. My apologies for being so long winded and thank you in advance for any wisdom you could bestow on me. — Flawlessempathy0114

Solution: Hi. Flawlessempathy0114. Android troubleshooting is straightforward — if software solutions don’t work, then hardware must be to blame. Add in the fact that the phone has been exposed to water and you have a solid case of hardware malfunction. That said, the only thing that we can tell you is to have the phone repaired. If you want to do the repair yourself, try to find a good guide via Google.  Our blog does not provide hardware troubleshooting and solutions.
