Since installing Liberty I have been experiencing a lot of random reboots. I've been trying to narrow it down to something I'm doing that is causing it, but from what I can tell it's completely random. It's especially obnoxious when I'm on the phone and it suddenly reboots for no reason. It's not a soft reboot either that was once an issue with the lockscreen, but a full reboot. It happens 2 or 3 times a day. Is anyone else experiencing this or know of a way that I could at least diagnose the problem?
