I noticed when i take a pic or video an then go back to watch or see the picture the screen will be bright but then starts dimming down. Is there a setting to stop that? Im sure its to save battery but its annoying.
If I'm understanding you right:
The camera app, by design, bypasses your auto-brightness setting, so therefore when you take a picture, your camera is brighter, then of course when you exit out of the camera, it defaults back to auto-brightness. I could be wrong, but I think that's what's happening.
