This small application allows you to change the brightness of the capacitive buttons (back, home, and recent tasks) on many HTC devices and a few non-HTC devices, including the HTC One X (both dual-core and quad-core models), the HTC One X+, and the HTC One. Users have also reported success on other devices, including HTC One V, HTC One S, HTC Desire HD, and Evo 3g. Root is required in order for this application to work. This application works on any ROM, including CleanROM, ViperXL, Cyanogenmod, AOKP, and MIUI.

Differences in the Pro Version

The Pro version receives new features and bug fixes 2-4 weeks earlier than the free version. That's it! Oh, and also the free version has a link at the bottom of the main UI to upgrade to pro. The main motivation to pay for the pro version is to get official app updates easily and automatically via the Google Play Store. If you're happy with waiting for updates or using beta versions then you can live a full and happy life with the free version.

Frequently Asked Questions

Which brightness setting is "stock"? It depends. On Sense based ROMs (eg. CleanROM, ViperXL) "Bright" seems to be the default. On AOSP-based ROMs (eg. CM10, AOKP) "Dim" seems to be the default. It all depends on how/if the ROM maintainer tweaked the default setting. The "default default" (ie. if you RUU to stock) setting is "bright". In v1.0.4, a "Default" button was added to allow reverting to stock brightness.

How do I get back to the default setting? The most reliable way is to click the "Default" button on the main screen of the application then simply reboot. Or, you can just set the brightness setting that is the default.

What happens if I uninstall the app? Nothing. Well, it doesn't change the brightness setting if that's what you're wondering. After a reboot, though, the brightness setting will revert back to the ROM's default setting.

Known Issues

"Dim" does not work on all ROMs and kernels

"Off" does not stick when "GV Integation" app installed

Feel free to bake the free version of this app into custom ROMs or publish it in other places. No need to ask permission from me. However, I am quite interested personally in different places that this app is used. So if you do include it in a ROM or whatever feel free to post a note to this thread to let me know! The app is licensed under the GPL, which means you can even take it apart and include it in your own stuff... I just ask that you honor the spirit of the GPL (unlike HTC's 120-day policy... grrr!)
