And it wouldn't come back on by pressing the power button. I thought maybe the battery needed charging. I thought that would be odd because the battery had to be over 60% when I was using the nav. Put it in my pocket and realized the phone was hot and I couldn't turn it on. Hooked a charger up to it, and nothing. Finally after a few mins, I held the volume buttons and power buttons together and that finally turned it on. WTF is this?
