Immediately following the Jellybean update to my GS3, my phone began to randomly restarts multiple times, even when I'm not touching it. This is occurring several times within a day. My phone also freezes up at least a couple times a day. The only way to get the phone to operate correctly is to remove/replace the battery, or sometimes just leave it alone for awhile, which will usually result in a restart, without me initiating it. Lastly, my battery drains really fast. I can no longer make it through a day on a single charge.
Am I the only one having all of these problems? If so, maybe it's just coincidental that the problems began immediately after the jellybean update.
