Auto brightness off, screen changes

[VooDooCC]

I think I've noticed it a few times before, but tonight I've been able to replicate it on purpose. I have my brightness at close to it's dimmest setting, yet in direct sunlight the screen goes to max brightness; hold it in the shade and it goes back dim.

Is this something I could have been utilizing all along, or do I have an app that needs uninstalled?

There is a thread discussing this already. It seems to be a thing.
