I think the phone over heats while in the pocket, mine reboots sometimes when it is in my pocket, and it shuts off completely other times and won't turn back on for a few minutes sometimes. I hate the thought of returning the phone, having to backup everything and reinstall it because you never get everything like you like it again without a lot of work. You also may get a refurbished phone too boot when you return your phone for warranty, but if it gets worse I will be swapping it out.
