Need help: My screen came out so I took the phone apart and re-glued the screen with some 1mm 3M tape. Now I reassembled it and it vibrates on boot and I can see the backlight go on because a corner of the screen is broken off… Also WhatsApp Web works. So the phone is definitely working, but the display isnt showing anything… I re-checked the main screen connector at the bottom and it is properly plugged… what can I do?
