I’m going to quickly cover how to enable the LED notification light in Android 7.0 Nougat, in this case on the Nexus 6P, so don’t go anywhere! If your device has a notification LED, we can enable it by going into Settings followed by Notifications, select the cog icon and then simply toggle the pulse notification light option on.
Keep in mind that while these steps apply to stock Android 7.0, the steps for your specific device may differ slightly as different phone makers apply different skins and change the location of settings around.
That’s basically all there is to it, the LED light should now display regularly when you have a notification such as unread email or SMS which is really useful as you don’t need to constantly power on the screen to check for notifications, which saves you both time and battery life.
The colour of the LED will also be different depending on the type of alert so that you will be able to determine what type of alert you have based on the colour. Unfortunately the colour of the LED can’t be changed by default, however there’s application called Light Flow if you’re after this functionality, I’ll leave a link to that in the post description if you’re interested.
