So I'm at work and grab my phone out of my pocket to make a call. Press the power button to bring it out of sleep....and nothing happens. I try a few more times and get nothing. So I wonder if I accidentally turned it off. I hold the power button down a few times and get nothing. Plug it into my charger, nothing. So I finally pull the battery out and replace it. Turns on fine, battery is at 90%. I've had the phone for 6 days, and have had it rooted and OCed for 3. I backed the OC down to 800mhz (had it at 1000) just in case it overheated, but I had the profile set for 550mh whenever the temp got above 41C... Why could this have happened? The battery is fine. I had GPS on but turned it off since it rarely connects in the building I'm in. If it happens again I'll be resetting to stock (so they don't void my warranty) and returning to the verizon store.
