Sometimes when I'm playing a game, I'll put it in sleep mode, pause, or it will just change screens and freeze. When I turn it back on, it will show the G6 screen at the top, and then just hang there. It will work again after i connect it to a computer, but it's a reocurring bug so... I remember it doing this a long time ago, and I think it just fixed itself, but i'm not sure. Any tips?
