Screen brightness too high on auto mode when in the dark room An Android-based HTC Desire S is set to "auto brightness" display mode. The brightness is adjusted okay unless the device in a completely dark room. In a dark room then display is very bright - tolerable, but really uncomfortable.

Is there a way to make it less bright without disabling "auto brightness" mode?
Short answer: no.

Auto brightness is usually a battery waster.

I like to use the Brightness widget, it will let you turn on/off auto-brightness or with one touch adjust the brightness to one of several presets.
