The location for the backlight sensor is...
Settings > Buttons > Backlight
Make sure the box is checked... if it is, you may still have to check the registry value listed above.
I have noticed on my device that sometimes in dimly lit room the keyboard backlight sometimes takes a few seconds to come on. Sometimes it feels like I can trigger the backlight quicker by sliding my finger across the sensor. maybe the moment of absolute darkness is all it needs. Anyone know if there is a registry setting to control sensitivity?
