Hello, I replaced the broken glass of my iPad mini 2 retina. After that, the screen show some bizard vertical lines and bands. When I rotate the ipad, those lines will change place or disappear. It seems miss 1/2 of resolution. See that battery icon ? It lost the 2 horizontal lines. Text rendering is more obvious. It lost anti-alias. The glass of replacement seems to be a suitable and solid product (Trop saint, lots of positive reviews) purchased on amazon. I even test another glass. But the problem persist. Is this problem due to the LCD screen or something else ? Please help !
