Backlit Buttons With Keep The Lights On
If you want to keep the LEDs behind your Samsung Galaxy device buttons on whilst the screen is on, try out Keep The Lights On – an Android app developed by XDA forum member Guardian_Bob.
One of the main reasons for this app, is for those of you who have installed i9000 based ROMs on your device. Although the stock ROM turns on the LEDs when you touch the screen, the i9000 based ROMs do not or have a timeout of approx 3 seconds.
Be assured that surface LEDs draw very little power, so no need to worry about battery drain. Additionally, Keep The Lights On 1.3 works with other BLN apps such as Blinky.
Keep The Lights On is a widget based app hence won’t appear in your app list. The app is available free from the Market (although a Pro version is also available with more features).
