iPad screen going black every few minutes
My elderly sister has reported that whenever she tries to do anything with her iPad, which is less than three years old, the screen keeps going black. After a short while the screen she was working on reappears - so she carries on, say, writing an email and then the screen goes black again. She says it is driving her crazy!
I managed to talk her into backing up her device and then 'reset' all settings, but the problem continues.
What else can I suggest before she has to send it back to Apple for repair?
