[Android Central Question]

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?

Everything works fine but the screen doesn't come on could be a problem with the digitizer, or a couple of things. A repair shop would be prudent. Good luck

Did the problem start immediately after you did your repair?

When I turn the phone on the display works completely normal but when it goes to time-out it doesn't go back on.

Yes, I didn't use it after the repair but the day after when I turned it on for the first time it strarted doing this.

Sounds like something is wrong with the power button even though it still works to turn it on. Could be a loose connection or something out of alignment that happened as a result of taking ot apart. Unless it's just a coincidence.
