My phone is dimming the display when I switch from any app to home screen. In apps the screen brightness is on its maximum value but everytime I switch to home screen the phone automatically dims the display. Adaptive brightness is off, night light and sunlight mode are also off. Is this a "feature" on Android 8.0 or something is wrong? I cant remember if the phone was doing the same thing on Android 7 but I think it wasnt.
