Upgraded to official 4.3 with complete wipe on my S3 for a couple of days already. Haven't use heavily but the unlock screen can get quite annoying. When sleeping, can be quite unresponsive when waking up. Sometimes 2-3 seconds to wake up. Cannot swipe anywhere when I want to unlock. If accidently swipe the clock, it wouldn't unlock.

However, I do like that now my applications can be "move to SD Card".

Developer options is now hidden. To enable back follow the link below. It is meant for S4 but works in S3 as well.
