Galaxy A7 2018 display won't turn after timeout

First Poster

Yesterday I replaced the broken glass back of my Samsung A7 2018. I did it myself because it's actually really easy. Everything works fine but the screen of my phone won't turn back on again when I press the power button after a timeout or when the phone is locked. Both the button and the display still work so I think it's a software issue but I'm not 100% sure. So far I've tried to update and factory reset the phone but didn't work.

Do you guys know how to fix this?

It does sound like something has gone wrong either by way of the accident that has led you to have to change the part on the phone or via the process of you replacing the part @xyco  .

 

As you've probably invalidated the manufacturer's warranty by carrying out work yourself you might be charged by a Samsung Service Centre for any work and or go to a Highstreet Store that advertises they repair phones.
