| | Re: Blackberry 9930 Screen going blank
I've had the same problem. Never had it power down but the screen goes blank and no button will bring it back. Only thing that will bring it back is to end the call. After a battery pull it's usually ok. What makes it worse, the problem is intermittent. Tough to pinpoint a pattern that makes this happen. I'm still on 7.0. Doesn't sound like 7.1 has addressed the issue either.
