iPad mini Anyone else with an rMini with auto brightness not working?

I just got an rMini and if I bring it to a bright place, it will brighten up but it will not go down if i bring it to a place with low light unless i shut the screen off then on again. Anyone else having this behavior? I have tried a restore already.

 

What kind of iPhone? My iPhone 5 works fine running the latest OS. Are you sure yours is set correctly? You have to go in a dark room, turn the auto brightness off then set the level of brightness you want when its dark. From that setting it will never go down even in the dark but it will get brighter when you go out of the dark room and then go back to the level you set it at very slowly when you go back to darkness. If you change the setting using the control center it will mess with its function and you'll have to reset it again. Always been this way since iOS 6.

For the other people experiencing the issue, is your auto brightness calibrated right as I wrote above?
