DoggNZ: Hmm....on my SII (with Automatic Brightness unticked), I could pull down the status bar slightly and move to the left to go darker and right to go brighter. However, since I installed a custom ROM the day I got it, I can't remember if it's a stock feature or not? Reason I'm asking is because it doesn't seem to work on the SIII?
I don't own an S2 but I'm sure I've read somewhere that it had this feature because a few articles I've read have said that Samsung removed it for the S3.
