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?
