    On reassembly, triple check that the camera lenses are clean and have no dust. Otherwise you have to take the motherboard cover back off to clean. And every time you take a phone apart, the chances of problems increases.

まとめ

To reassemble your device, follow these instructions in reverse order.

The best way to secure the new screen is with a sheet of custom-cut double-sided tape. Apply the tape to the back of the screen, then carefully feed the display and touchscreen cable through the frame. Align the screen and press it into place.

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?
