Here is a solution based on the user experience when you experience random reboots on Galaxy S III after JB update. Please note, the results may vary on each device:

  • Disable Downloads in Settings > Application Manager > All.
  • If you have previously enabled face unlock feature, you should disable this feature.
  • This can be the last solution before bringing your device to a local store, by Factory reset your phone, so your phone will back to factory default settings. Look at Settings > Backup and reset > Factory Data reset. However, all the data stored on the internal storage will wiped, so do not forget to backup. This can be the best solution as a factory reset will erase all the settings you made on ICS (Android 4.0), so it does not conflict with the Jelly Bean firmware.
  • The last solution that you can do in case you are still within the 14 day return is replace your Galaxy S3 with a new one, just visit the local AT&T store.

    I have the gs3 international with the same issue as described above and i’ve noticed that if i use the app called Fast Reboot frequently then my phone will not reboot itself unexpectedly. I’m kind of noob so maybe someone more qualified could confirm or dismiss this.
