I've come to the conclusion, after my Razr XT910 was offered an upgrade to ICS, the OS has become corrupt and needs a reinstall. I just don't know where to start. I have tried clearing caches, rebooting, hardware rebooting etc... but the phone seems to be degrading. I originally purchased it from Kogan (online) and found they had an Asia version of Android. My first suspicion is (if Asia specific) that it doesn't work all that great here in Australia. This is a long-shot but it is a possibility. Google play appears corrupted as more and more apps come back with "Package file is invalid". I have reset the cache, tried several google play fix apps but no luck. The camera and video camera intermittently works, other times no start... but worst of all, the phone reboots itself randomly, sometimes several times a day, without any user interaction. It just sits there and decides to reboot for no apparent reason. It has also done this during a phone call! Forget about warranty; Kogan has a support team by name only. Their people are as useless and/or technologically illiterate. I downloaded ICS via the 3G network and think it may have downloaded with errors, but still successfully upgraded. Can anyone tell me: 1) where I can download ICS or Jellybean 2) where I can find step-by-step instructions to do a clean re-install thanks.
