Both my 8130 Pearl and Dad's 8330 Curve, when you are doing something on the BB, be it on an application or sending a text or whatever, the screen always after a few seconds dims down from bright to a not so bright contrast. It doesn't turn black or off, just dims down while in the middle of doing something. It doesn't really bother me, but it does Dad. I figured since it was going on with both the Pearl and the Curve it is a battery saving tactic on all BB's. ??? Could be wrong, but that is my guess.
My question, for Dad, is.....can you adjust a setting anywhere to keep that backlight from dimming down at all or at least adjust the period of time it takes for it to dim down???
