One of the common problems that many LG Optimus G pro users face:
Auto-Brightness:
The auto brightness function on LG works different as compared to other phones, you have to set the arrange first and apparently the auto brightness will around that
Say you have it at 75% brightness and auto brightness on, the level will go up to maybe about 85% while outdoors and maybe to about 65% in a dim room. Set it at 35% brightness with auto brightness on, the level goes up to 45% in a bright area and 25% in a dark area. That's how my old iPhone 4 used to work.
