The last 2 phones I have replaced the screen assembly I have encountered the following problem, screen seems fine to start with but when any think is pressed or anything pops up the screen gets horizontal lines across. I was thinking it was the new screen but with it being the last 2 replacements I’ve done, i’m beginning to wonder if its something I’m doing. Does anyone else have this problem.

I’d question the quality of the screens, are they from the same supplier? If yes, try sourcing out a screen from another supplier and see if there is a difference.
