Put Your Android Phone’s Notification LED to Use With Light Flow

Many Android phones have an integrated notification LED. With Light Flow, you can have your phone’s LED notification flash different colors depending on the types of notifications you have waiting for you – your phone can communicate notifications even with its screen off.

Light Flow requires a notification LED that can display different colors, so this will depend on your phone’s hardware. The Nexus 4, Galaxy S III, and a variety of Motorola and HTC phones all have the required hardware.
