I was thinking about formating my phone for a pretty long time because it was over heating every so often until my colleague just said he want to try and test the note 3. so he ended installing the long awaited update lolipop for the samsung note 3. Why long awaited because tons of the other phones already have the android update for lolipop but samsung was taking a long time to get it released. Then he formated the phone and ran the antutu bench mark. on that day he was saying it was like running slower than a snap dragon 400. but it was a snap dragon 800. The next day he was saying it was performing normally and it was because the device was overheated.
