My Q10 seems to have a mind of its own. If seems to reboot quite often. If you put it down too hard it reboots, if you pick it up too fast it reboots, if I move too fast with it in my hand it hangs up on the person I’m talking to and it reboots! Wtf??? It’s a great phone but this is obviously a design flaw. I called tmobile and they have no answer. I don’t want an iPhone but I might have to get one. Anyone have any ideas?
