iPhone 12 Pro auto dimming with all setting turned off.

My 12 auto dims to around 50% brightness even with all the settings for that turned off.


I have accessibility - display and text size - auto-brightness turned off


I have dark mode , night shift , True Tone turned off


In display & brightness I have brightness turned all the way up and appearance on light mode.


phone still auto dims. Is there another setting somewhere or is this phone broken ?

iPhone 12 Pro, iOS 14

Settings/Accessibility/Face ID & Attention/Attention Aware features. If the phone does not see your face it dims the display when this is on.


Also, the screen will dim 30 seconds before automatic lock, as a warning. That can’t be changed.
