Weird, my i9100 has been playing up today a bit.
Getting extremely hot and draining the battery a lot quicker then normal. Looks like the Music app was the main contributor to the battery drain. Powered it off for a bit now to let it cool.
Some condensation seems to have built up a bit behind cover around the camera lens. Also a little odd. While it cools and has a large dose of mains charge, I'll grab the latest official samsung rom for it.
