Re: Okay, i bought an epic 4g, because my old one had trouble turning on.
If your talking about your auto rotation issue, that's going to be tricky because I can't remember seeing anyone having issues like that on the E Touch.
You can try calibrating your sensors and then flash a STOCK rom without moving the phone. You must try a stock build that will reset your phone, this way if there is something screwed up it can be fixed by flashing a stock rom.
Try a jellybean build like Garwynn's Ga10 or newer.
