S7 black screen and unresponsive

Hey everyone,

Having issues with my Galaxy S7 32gb, 2.5 years old, whereby the screen is completely black and unresponsive, and I’m unable to switch it back on, or enter recovery mode. No previous issues with this, and no drop or water damage.

**Background to the issue
Unplugged my phone from an overnight charge and was browsing on Chrome, when the phone hung and wouldn’t respond with any buttons. No external stimuli to cause this, aside maybe heat - have been travelling around Asia for 3.5 months whereas I usually reside in the UK. No hotter on this particular session than normal though - was in an A/C room.

After a little while of no response the screen eventually went black, as if switched off, and wouldn’t respond.

**Steps I’ve tried
1. Holding the power button - no response
2. Vol down + power - no response
3. Vol up + home, then + power - no response
4. Plug in phone to charge - no lights and no response

All in all it seemed like the phone was dead and unresponsive, despite having almost 100% battery when I was using it. However, I left the phone for the day to see if anything changed when I’d let the battery run down. After a few hours I tried again and steps 1-3 still didn’t work, however plugging my phone in caused the Samsung Galaxy S7 splash screen to show. Next what happened:

1. Blue screen ‘Installing system update’
2. Followed by a blue screen, with a yellow warning sign and white android logo, with text ‘No command’
3. Recovery screen then showed
4. Performed a clear cache partition
5. Phone reboots and gets to my unlock screen, but shows 0% battery and dies again despite being plugged in
6. Reboots to unlock screen again and then freezes
7. Phone now back to its original problem - black screen, unresponsive buttons, unresponsive to a charger

**Where I’m at
I’m now back to having an unresponsive black screen phone. It feels like if I leave the battery to drain again I might get another shot at getting to the recovery menu when I plug it into charge.

If I do, is there anything else I can try? A factory reset perhaps? Or does anyone have any similar experience or ideas as to why the phone is behaving this way? Could it just be getting too old and dying?

I need to try everything I can to self-troubleshoot and fix myself as I’m still travelling for another 3 months and can’t realistically send the phone anywhere for repair.

Thanks in advance!
Jamie

In the UK there is Samsung Experience Stores or Samsung Service Centres who can usually help in house so there is no need normally to send the phone away.

 

The manufacturer warranty has elapsed as this is 2 years but they may still be able to help as long as the phone shows no signs of accidental damage and the water indicators have not been tripped @Jamicar 

 

I wish you all the best with this situation.

I have tried all the same things and having the same issue, i really like this phone (S7 Edge SM-935F)and would like to fix it.

 

For me the screen froze on uninstalling Elisa Elamus application, then phone turned off and hang on android logo. Next time it just would not turn on and now i have a dead phone.

 

What could it be?

My phone died in a similar way, I was uninstalling Montorsport Manager 3 cause my phone had been complaining of low space. I was uninstalling several apps and this one was one of the big ones (370MB). It was uninstalling and suddenly it went black. I think at some point I saw the clock appearing so I just pressed the Home button to see how it was and it went black. After that I googled and tried those Vol.Down+Power and other combinations but nothing.

The LED was blinking as if it still detected there were new messages but I couldn't do anything. Eventually the light died and the phone is not charging.

 

Any other ideas?
