Are you sure you are actually shutting it off? The power button quick press turns off the screen, but dows not power off the phone. You hold the power button until a menu comes up from which you select Power Off?
yea, i made sure that i turned the phone all the way off. the phone would go through the process of powering off and then any where from 1 hour + it would randomly power itself back on. i returned the phone for a new one. the new one i got did it Once and has been working pretty well since (fingers crossed). only prob im having now is that i see Verizon may be coming out with a Newer, Better phone in a month or so. I really like the Bionic for what it is, but not sure if i should stay with it, or return it and hold out to see what's coming out...
