I have heard of people having rebooting problems when exiting apps, but have not heard of a fix. This happens to me about 60% of the time when exiting out of an app. Then I have to wait while the phone reboots before I can continue on. A battery pull or shutdown will stop it for a while then it starts back up again. It seems like it is getting a little bit worse and I'm sick of it. Any body have a cure? I am stock GB.
