I got a VM Rise about a week ago, my first smartphone, and I'm rather impressed, for the most part. However, it's got this annoying habit of shutting off on me, and it won't turn back on. I'll take out the phone, the screen will be black, and the power/unlock button will do nothing no matter how many times I press it or how long I hold it. To get it to work again, I have to either remove and replace the battery, or plug it into the charger, and then it will come back on. I'm not sure whether the phone is just frozen while locked, or if it's actually turning itself off. When I put it on the charger and hold the power button, it undergoes the boot sequence with one of those obnoxious little songs Virgin Mobile likes to put in their startup sequences, yet when it freezes it doesn't seem to go through any shutting-down sequence. I thought I had the cause narrowed down to the SD card, as it seemed to happen most often when an SD card was in, and once, I inserted the SD card, and the problem immediately occurred. Yet, it also sometimes happens even without the SD card in. Calling tech support, they instructed me to do a factory reset, and if it was still having trouble after four hours, call again and they'd send me a replacement. I'll do this if all else fails, however if it's possible to fix it without having to wait for them to ship me a new one, that would be much, much preferred. Thanks in advance!
