'AutoBrightness' Offers a Better Automatic Screen Brightness Controller Than Apple Does
For those of you where screen brightness depending on the lighting conditions around you is a big deal, you may want to take a peek at a new free jailbreak tweak called AutoBrightness
by iOS developer K3A.
AutoBrightness does two major things: 1, it keeps your screen at a good brightness level depending on how bright or how dark the lighting conditions are around you; and 2, it does so much better than Apple does. For this reason, the developer recommends that you disable Apple's Auto Brightness feature from the Brightness and Wallpapers preferences pane in the Settings application after installing AutoBrightness... so make sure you do that or you won't get the expected results.
After installing the tweak and giving it a try, you will notice that as soon as your ambient light sensor detects a high amount of light, your screen brightness will rocket up. As soon as the ambient light sensor detects a small amount or no light, your screen brightness will quickly diminish to a very dim state. Apple's Auto Brightness feature lacks a quick dim when the light decreases, which for some makes the display feel like a flashlight straight to the eyeballs.
AutoBrightness is completely free and doesn't have any options to configure because it's completely automatic! If you would like to give it a try, you will find it in Cydia's BigBoss repository right now.
