There is a discolored spot in the middle of screek when it's popped in
I'm repairing a 6 plus, and it has a discolored spot at the top of the screen, a little to the right. I tried loosening the earpiece bracket screws since I've heard this can cause discoloration but it didn't help. The discoloration goes away when I test it before closing it up, but once I pop the screen down into place it shows up again. I'll be grateful for any help.
Is this a good question?
