You’ve all been there. You’re sitting near a window or a lamp, reading an excellent article on your iPad — perhaps a well-written How-To from Cult of Mac — and your iPad’s screen Auto Brightness is going haywire. You slide open Control Center, and set it back where you want it, and continue reading. Then, you turn the iPad a little too far towards the light, and the screen brightness creeps up again.
In iOS 10 and prior, you’d just open the Settings app, tap Display & Brightness, and hit the switch for Auto Brightness. In iOS 11, that option has disappeared. The good news is that it hasn’t gone — the Auto Brightness switch has just moved.
