There is fixed level of auto brightness and brightness slider moves on its own based on the light sensor - This is Adaptive Brightness ??
Adaptive Brightness - ON = Auto adjustment of the phone brightness based on the ambient light sensor.
Adaptive Brightness - OFF = Manual Brightness Adjustment by user.
Well, as it says in the article. This was a feature of Android L.
It is not there in the stock version of Android N.
I meant Auto Brightness is not there in Nougat. I have not used it and it was a feature of Android L.
7.1.1 and 7.1.2 have the same settings.I didn't see any change in the display settings. The Adaptive brightness option works just fine for me.
