Rookie prob...I can't find where to adjust my screen brightness. I see where I can auto adjust screen, but no manual adjusting of brightness. I am trying to tweak my battery saving and I've read where the screen brightness is a big drain. I do have my battery set to battery saver mode now. I did read where they said it would save on my battery but the 3G cuts off after 15 minutes of non use...maybe it was longer than that.
