I took my personal Droid Ultra (emp edition) apart today to see if it actually does have an LED or not (for notifications). The answer is Yes it does. There is a LED right next to the light sensor on top, from what i have read from others i guess it just blinks when your low on battery and you have notifications instead of it lighting up the screen. I was assuming it would have been by the earpiece but i guess not, nothing was there. I also assume with root or something, maybe the LED can be enabled for those who would like it as a notification all the time.
