The brightness value got by Screen.brightness is different from the value of device brightness

[mis0025033]

Hi,

The version of my testing device is android7.1.1, I found if the adaptive brightness feature is enable, the brightness got by Screen.brightness is different from the actual value of the device brightness.

If I disable the adaptive brightness, the brightness value will be the same as the device brightness, so what can i do to get the actual brightness value when the device enable the adaptive brightness feature??

Thanks!!!!
