Chad Williams on iOS 6 features you may not know about
The auto-dim feature got significantly improved in iOS 6. The best improvement is brightness adjustment in the lock screen. Before, in a dark room, I would be blasted with the iPad or iPhone’s default brightness before sliding to unlock and having it dim down to match the room’s brightness. Now, from the moment the screen turns on, the brightness is appropriate.
It is the little things.
