So I thought auto brightness would crank the brightness up in the daylight and dim it in dark environment automatically? I have auto brightness 'checked' and still have the ability to move the slider bar. That tells me that the autobrightness range is adjustable - maybe I'm wrong. Anyway, to see in bright daylight - I like the display when the slider is at 100%. however, with the slider at 100% and autobrightness selected...I'm still blinded at night and have to turn down the slider. Effectively I have no autobrightness function...I still have to manually adjust up and down depending on my environment. Not sue how the camera senses the brightness of the environment...maybe my screen protector or ballistic case is covering up some sensor? I'm I missing something obvious?
