How do I activate notification light on moto g4 plus?##
You can’t because it doesn’t have one.
You will have to look in the playstore but an app may flash the camera light when a message comes in notification flash - Android Apps on Google Play
I use this app and get sound notifications but it customizes in all one area. I have the paid version and can custom edit what & how many I want there instead of the 5 app limit on the free version.
Hope all this helps.
