First Nokia Lumia 920 Issue

So after having the phone for over a week now after the Telstra debacle I have encountered my first issue. Last night while talking to a work colleague the phone first decided to reboot and then promptly hang. I left it for 5-10 minutes with the screen happily glowing with the Nokia logo.
A quick google search suggested a full factory reset would fix the issue. Not wanting to go this far initially I did a soft reboot vol down + power + camera and release on vibrate. Within a minute or so the phone was back up and running correctly with no issues since. Hopefully this won’t become a regular problem although from what I read a fix is already on the way. The sooner the better as this is the last thing that MS/Nokia needs for WP8 and a flagship phone.
