As discussed in other threads I've been working on a notification app to use the 5 LED on the Gemini. I have called this app GeminiLED and a version now available for people to try if they wish.
This first version will light each of the 5 centre LED for notifications colours as follows from left to right:
Viber - magenta
WhatsApp - green
K9 Mail - red
Handcent Next SMS - blue
Dialer (call and missed call) - cyan
NOTE: This app needs access to notifications to work. Select Settings, Apps, Settings (gear wheel), Special access, Notification access slider on for GeminiLED
Due to the (sensible) way Android goes in to a 'doze' mode when the screen is off, I have not been able to implement reliable flashing. If Planet release develop tools as they have said they are going to then there may be some methods available that I am currently unaware of which will allow me to revisit that. I've done some rudimentary testing and having the LEDs lit continuously does not seem to have any discernible affect on battery life.
The app to LED configuration is hard coded in this version. User configuration of what LED responds to what app and in what colour is now under development.
The apk is available
