What kind of indications are there that the phone has rebooted? I used to think that the up time was indicative, but I've seen my phone reboot itself without resetting the up time. Sometimes turning on the screen, I'll get the Location notification that shows up when turning on the phone. I can assume this comes up because the phone rebooted. Would it come up any other time? Is there anything else that would indicate a reboot? It seems like it's happening more frequently to me.
