Today I have them repair my iPad 4 screen,(the glass has cracks on corner).after one hour waiting, I found out lines all over my iPad’s screen when he hang it over my repaired iPad. I told him it’s not ok to have lines all over, he said those lines will disappear after few days, so I’m going to give a try, and leave this comment as prove. I will update my review if the line disappears in few days.
