Capacitive buttons aren’t generally the most tweaked items in the Android hacker’s arsenal. While they can often be too dim, many find them way too bright.
Having the backlight too bright can distract users attempting to use their devices to read or play games in dim environments. After all, it’s a little hard to concentrate with that home button glowing at you. In fact, the capacitive buttons being too bright was a major issue causing light leakage for the HTC Amaze 4G. Now owners of the HTC Rezound can lower their brightness as well.
XDA Senior Member rsage has released an easy-to-install script that will lower the brightness of the Rezound’s capacitive buttons. The idea came when rsage found a script that permanently turned the lights off or on. He then figured that this would be a nice in-between solution for Rezound users.
The installation instructions are pretty basic. Place the update.zip on your SD card, flash in recovery, and reboot. The modification is currently only compatible with Sense 4.0 ROMs—as any version below that is actually compatible with LeeDroid Tweaks, which includes a similar mod.
