Automatic brightness is not working for me. I'm on a clean wipe, and everything else works wonderfully. Once I power on the phone, the auto-brightness only increases, it never decreases. i.e.: it may start at brightness 70. Then, if I hold it under a bright light, it goes up to brightness 240. But if I shut off the lights in the room, it stays at 240, even if I give it some time and turn the screen off and back on. Does anyone else have this issue? To note: this happens regardless of whether I use custom light levels in CM settings.
