White lines all over the screen
I'm using ipad mini 2 and I've just upgrade to 10.1.1 last night. After that my ipad's screen becomes like this
Then I downgrade my ipad to 10.1 and the problem is still remain, but if I lock then unlock it, the screen backs to normal again in about 30sec to 1min then everything becomes fragile again. Please help 😟
