Although automatic brightness is a fairly common feature these days, there aren’t always many options to change how it behaves—especially on some stock OEM-skinned ROMs. While there are a multitude of third party apps available, many seem to be filled with too many settings and options for some people’s taste. Well now there’s a middle ground in the form of Yet Another Auto Brightness by XDA Forum Member andrvo.
The application does exactly what you would expect, and has a nice interface. You can easily adjust the screen brightness manually via the app notification, should you need to, as well as tweak the range of the auto brightness to suit your specific need. There’s also a night mode to increase accuracy in lower light conditions. The developer is also aware that some people may experience problems with their ambient light sensors on custom ROMs, and has provided a small app to test the sensor for yourself.
YAAB is completely free, open source, and compatible with Android 2.2 and greater. Check out the application thread for more details.___________________
