Don't know if anybody else has noticed this but the Nexus 6 does have a notification LED inside the top speaker. Been messing around with Lightflow and I have got the light to light up under certain conditions.



Edit - Just so it's right at the top. This is what you need to know:

You'll need root but with that try the following:

Choose root mode
run every command as root and
direct mode
Make sure "su"/superuser has access granted for all requests

Then go into lightflow, notification settings and you should have a
"mixer" option. Enable that and you should then see options to set the
red, green and blue leds and also an option to set their brightness.

The brightness is has a 255 max value (0 being off) - (255 max brightness) and it should work.

The led won't flash but you can mix them together to get different colors. Technically you don't need to use the mixer but there's more control with it from what I remember.

You will need the paid version of lightflow. The free version is not updated frequently and doesn't support all the required settings.

Also worth noting, that you can enable control of the "Charging" LED which is green only. If you use that LED, it's slightly brighter than using the standard "green" LED.

Also, brightness levels for the Charge LED are variable between 1 and 40. Over 40, it's no brighter.

The RGB LEDs seem to be on or off. I haven't seen any difference between brightness 1 and brightness 20 (or any other higher number, I just use 20 because the /sys/devices/leds-qpnp-f0067200/leds/red/max_brightness file indicates 20 is the max for this LED - it's 40 for the Charge LED)

K, I think I have steps to reproduce. Looks like you have to enable "Root mode" and "Run every command as root" then enable control of the "charging" LED. Then set up a notification to use that LED. The light doesn't respond to the different blink settings. Always seems to be solid for a few seconds then flashing for a few then back to solid.

Awesome find! I'm assuming it's multicolored?

As long as we have the hardware, the software will come in time. Loving this! Great find.

And it's always green, no matter what color I tell Light Flow to use.

The Moto X had one of those with the sole purpose to light up to indicate a charge when the battery was too depleted to power the screen to indicate charging. That's probably the reason it is here as well.
