I don't know how many of you came over from Windows Mobile Based phones, but I came directly from a WinMo Phone. Coming from a WinMo phone, I've always loved to use this app called Lumos. Lumos was a app that a dev created which uses to Proximity sensor to check the lighting background of the surrounding. It will then use the sensors and the outdoor surrounding light to adjust the brightness of the phone. This saved a lot of battery for WinMo phone. Was wondering if there's such an app which does something similar? The stock autobrightness doesn't seem to be saving much battery, unless i'm wrong.
