What about the ipad mini2 screen? Just take a picture.
This problem is very common in iPad series. I searched a lot on the Internet, and if I take it to repair it, I will definitely say that the screen is broken, and I need to change it or make some money after repairing it. I'll teach you a lazy way. Turn off your phone first, then take the ipad, with the glass face down (some people say I shot it vertically like a fly, but I shot it flat anyway), and pat it hard against the thick quilt. Don't be reluctant. Pay attention to how thick the quilt is, and don't crack the screen glass, hehe. Take more pictures, turn it on, no, do it again. My machine is too good. The reason is very simple, the screen socket is loose, and it is healthier to shoot, hehe.
