ipad mini3 with ios12 problem
Once I updated ios12 to my mini ipad3, the screen went black / gray every time I unlocked the ipad from locked/ covered the ipad. This makes me to restart every time after locking the ipad.
I also tried to update/restart/reset/restore the ipad but these did’t work and also lost my crucial document on my ipad despite backing up to the computer.
the problem didn’t happen when I used the old version of ios, 9 and 10
Does anyone encounter this problem? And how you fixed it?
Thank you
