Why's my screen dark & diagnostic kept showing up then shut itself off
I got my phone last year and now my phone kept shutting itself off and the only way I could turn it on is when I plug it in, and now that it's on, Diagnostics would show up ask a question and if I exit Diagnostics, it would power down by itself... What should I do? I have turned it on and off a lot of times and it's still happening.
Is this a good question?
