hi my phone reboots itself every now and then. when i make a call, it will shut down after 1 mins or so and reboot again. It is killing me. I tried to do a factory reset, it shows " the process com.android. phone has stopped unexpectedly. please try again" I tried several times and it is the same message. what should I do now??? please help, thanks a million! p.s. i uninstalled' some of my apps, and cleared my call log, etc. it doesn't work.
