My power button on my prevail won't work. It wont turn the phone on, off, or put it in sleep mode. Only way I can get screen back is to plug in and/or unplug charger. Had this problem about a week or two ago and had to hard reset my phone. I would hate to have to keep doing that. I haven't rooted the phone or downloaded any new apps. Does anyone have any advice? Thanks and hope everyone is having a good weekend.
