    Um, I have my phone set to autobrightness. I am in a really dark room. I hit the wake button on the phone and it's really bright, but it goes to the main menu and becomes incredibly dim. Why the hell is that?

    That's normal, unfortunately. The sensor apparently doesn't take a reading until you unlock the device.

    No, I mean it's bright when I unlock it, but it loads the main menu and dims down again. Shouldn't it be really bright in a dark room? (ie: the opposite)

    no think about it… if you use your phone with the lowest brightness setting in a dark room you can still see it but when outside in full sunshine you wont be able to see it at all, you would have to turn up the brightness. this is what the ambient light sensor does.

    This is correct. It's amazing how many people get this backwards. ;)
