My screen locked up on me! I had it connected to my car's bluetooth. I went to shut off the bluetooth (while still in the vehicle) and the screen was locked. I turned the screen on and off, pressed all the various buttons, but no dice. So I just shut the screen off, unhooked it, and went in the house to mess with it there. When I got inside, it opened right up. I know the screen lockups were a common problem in "the early days", but haven't read of many complaints about it lately. In particular, after the last update. So just checking...how are others doing with screen lock ups these days? Yes, or no? Thanks.
