If you’re watching a video on your HTC Desire and you find the light from the hard keys on your Android device distracting, there is now a way for you to turn them off!
Originally requested by an XDA forum member, user mercianary has posted the solution. You’ll need to copy the command posted by mercianary to a text file on your SD card, save as a shell script and then run it on your Desire using GScript Lite (available free from the Market).
This method will create a new icon on your screen which will let you turn off the hard key button lights. The lights will return after certain events, for example, locking the screen.
Confirmed to be working for Android 2.1/2.2 (Eclair) only.
