I had a different reaction to the notification led. I don't like my electronics glowing or blinking in the dark. I still liked my old android tablet, but it had to sleep face down because I could not turn the LED off.
You realize that there is a built in android setting to silence notifications if you lay your phone screen down. It's my favorite feature! No vibes no blinking lights. Silence.
On my phone the notification LED works as a charging/low-battery light. I can't use my phone in the dark when the LED is on, because it's so blindingly bright I can hardly see the screen.
I've covered the lights on several of my devices with black nail polish. It works pretty well. Some of them have angles that it won't adhere to very well, but even then it's a lot less obnoxious.
One coat to dim slightly, 3-4 to block light effectively.
Yeh, I thought I wanted a notification led again but once you have it you realise it's pointless. So many things can notify you about stuff you don't care about.
Nice to have and disable if you don't like it though.
