Blinker – LED Notification for Incoming SMS and Call Notification
Making more use of the charging LED on your Android device is a much requested feature from XDA members, and there have been a few apps developed for this purpose for various devices.
XDA forum member djbrutale has also developed an Android app to make use of the LED, this time on the Google Nexus One, although it’s possible that the app may also work for other Android devices.
Blinker, uses the charging LED to notify the user of received SMS’s and missed or rejected calls.
Additional functionality includes the option to set the colour of your choice from blue, green, red or amber and also the blinking speed of the LED.
Once the SMS has been read, or the the Call-missed notification has been deleted, the LED will turn off.
djbrutale has stated that for some devices, root may be required.
