I am having this same problem. When I dock my phone, it automatically docks and goes to the "dim" blue screen setting. When I hit the light bulb, it flashes to the "normal" red screen for a second, and then goes black. I hit where the lightbulb is, and it goes back to dim mode. I want the normal, red looking, bright screen to show up...it's gone.... It's driving me nuts, I've googled and searched for days, and the only thing I've come up with is: Trying the camera button to wake Application/options/disable sleep while awake setting (or similar) help... EDIT: I JUST FIGURED IT OUT! I turned on "Auto Adjust Brightness" in the main settings, and it fixed it.
