Yep. It does auto-adjust, but it doesn't seem to be very active as the 4 and 4S were. I wonder why that is.So I've noticed that the 5 doesn't seem to adjust brightness the same way the 4S was on the iOS 6 GM (or beta 4). With my 4S it would adjust all the time or look dimmed when I took it out of my pocket at first but the 5 seems not to be doing any auto-adjusting even though I have auto-brightness on. Just me or had anyone else noticed that too?
