My screen occasionally blacks out - often when I turn the phone from horizontal to vertical position or vice versa. The screen goes black, then turns on, then goes black again and so on. Feels like a loose connection or something. For some reason it happens more often when I have the phone placed in its leather protection case.
By the way, I think that my phone is just an Xperia - if there is such a model.
What to do?
