...but I can't seem to figure this one out. Running stock JB, with auto-brightness off. When I go to the mail app it dims my inbox and any mail messages I read. When I go to mail settings (or out of mail altogether) the brightness goes back up to normal. Can't seem to find what's making this happen. Any ideas? Thanks.

The Galaxy S3 has an option called "Auto adjust screen tone" which might be the cause of the problem.

Thanks for the suggestion. I tried turning that off and rebooting, to no avail. That did head me in the right direction, however. Turns out the problem was caused by the Settings > Power saving mode > Background color being checked. Unchecked it and voila, no more issue. Thanks again!

Makris, do you keep this setting turned on or off? I keep it off cuz I don't see any difference. Is the color/screen tone that much better if I leave it unchecked?

I have it checked because it helps save power.
