when i go to settings to adjust my display brightness, like all N8's we have a MINIMUM all the way to MAXIMUM setting. there are actually 5 steps between min and max. 1 being minimum, and 5 being the maximum. Well my 1 (minimum), level 2, and level 3, are all the EXACT same brightness. However once I go to level 4 or to level 5 (maximum) then I see a change. But levels 1, 2, and 3, it does not get any brighter or more dim when I change between these 3. Does your n8 do this?
