Is the Low Brightness setting really low? Microsoft should decrease brightness in Low Setting. Or better give us a brightness control slider. But chances of brightness slider in WP 8.1 are slim. So better decrease the brightness in Low setting, or add 5 levels named Lowest,Low,Medium,High,Highest. What do you think. It works with Auto Mode,but sometimes screen begins to flicker in auto mode and only option to stop that is to disable auto mode.
