I guess I'm assuming it works like my Macbook Pro, where I can go into the "Display" system preference and visually see the slider adjust (and the monitor/keyboard dim or brighten) as I turn on/off the lights. But is it different with the iPhone? Because I set it on "auto-brightness" yet wheter I'm inside or outside or whatever, I check, and the slider is at full brightness (all the way to the right). What's going on? You guys gettin this?
