I've had my vx6100 phone for about 4 months now and only within the last few weeks it has been shutting off on me with the battery fully charged. I have noticed that it mostly happens when I lose signal or it's searching for service...I go to flip open the phone and it just turns itself off. It's really annoying because it also happens when I receive a call that I try to answer but the phone dies on me. One time even after I turned it back on it turned itself off again a few seconds later. I'm thinking it's some kind of power save feature and I'm wondering if there's anyway to turn it off. There's also a new firmware upgrade? T6NVZV03 ? Hmm, I wonder if that will fix it. Do we have to go to an actual Verizon store or can it be done at any kiosk at the mall? Any help is appreciated, thanks.
