Has anyone been having spontaneous reboots lately? Over the last week or 2 I have had several unplanned inconvenient reboots. Some when sending a text, some when hanging up from a call, and one in the middle of a call. I've had this phone for 6 months now and this was never an issue until recently. My Bionic is stock on 902 and not rooted. I'm about ready to try a factory reset, but don't want to have to set everything up again.
