LED Notifications

Look in settings under Display. I would guess that LED indicator is turned off.

Nope. I was right. If you have silent notifications selected on any of your apps the LED will NOT blink. I am unsure how to fix this. I have seen something on another page saying download a 1 second silent ringtone, but unfortunately, there is no way to put it in the notification sounds. Samsung really screwed up on this one.
 
Led notification is a bit disappointing on the Note 8 orange for charging blue for email or messages my S7 or Note 7 had multiple colors ,you do have to have sound enabled for your LEDs to work

My gripe is with the led size. It's quite smaller than what I'm used to on the Note 4. Blue isn't too bad, but other colors like green are really hard to see. It's forced me to use the always on screen (since edge notifications don't work).
