Adaptive brightness issue
When I turn off adaptive brightness in settings, my screen goes darker. This happens even if I'm first turning display to full brightness, and then turn off adaptive brightness. This results in me having a better/brighter screen when I leave the setting "on" in screen settings. Why is not the full-brightness-adaptive-on-mode as bright as full-brightness-adaptive-off-mode? It seems to me that the black becomes darker when I turn off adaptive brightness, and the display in general becomes more dim.
