If you are tired of clicking through your settings menu and sub-menu to turn the auto-backlight on or off on your HTC HD2, why not try out XDA forum member react‘s little app?
It’s a simple application that toggles the auto-backlight function on and off. Normally, the auto-backlight adjusts according to the light sensor, however there may be times when you want to turn it off completely or remain on indefinitely.
AutoBacklight will appear as an icon in your programs list, and clicking it changes the auto-backlight setting from on to off and vice versa.
To download the program or for more information, check out the application thread.___________________
