Who has an Android smartphone such as the Samsung Galaxy or a Sony Experia with the notification LED, can customize the color of the LED so that it flashes differently depending on the notification.

If the color of the luminous LED is different for each application, then it also becomes useful to distinguish between more or less important notifications.
On Android there is no setting to choose how to illuminate the notification LED.
