Most Android smartphones or tablets come equipped with an LED notification light. The LED notifications are a great way to find out whether your device has any new notification to show you, without having to turn on the screen. The only limitation of this method is that your phone should have an LED notification light. While most devices have this LED light, not every phone is equipped with it. In such a case, you can use an app like Back Light Notifications (BLN), that uses capacitive touch buttons to double up as LED notification lights, but the only problem with this app is that it requires root access.
