Toggle Blue LED on HTC Desire
When his HTC Desire crashed, XDA forum member ChaosR discovered that his Android device had some extra LED colours. Aside from the known red, green and orange, ChaosR saw a flash of blue and purple!
He was able to replicate the bug once, and managed to get a snap of the purple to prove to fellow XDA members that he was not going crazy!
After stirring up some interest in the forum with the news of these extra colours, ChaosR has successfully coded a little Android app that can toggle and disable the blue LED.
Currently under testing, but confirmed to be working by various XDA members running Stock ROMs, ChaosR has mentioned that he is working on further developing his app to incorporate notifications.
