Forgive me if this has already been found but the Moto X has a notification light. Everywhere I've read including critic reviews said the moto x only has its active notification system.

I stumbled upon this with my defective moto maker xt1053. Somehow it came with a corrupt system from factory that even rsd lite couldn't fix. Anyway, I have a replacement on the way but I've had no way to turn it off. This morning I was playing around with it and plugged it in via USB to my computer. Battery graphic popped up as it would anytime you plug in with the phone powered down. The phone then showed 0% and to my surprise, a bright green led light long-blinks through the speaker grill!

My question now is... Is there anyway to enable the light under normal circumstances? I love active notifications, but if my phone is face up, I'd like to know if I have a text, etc with out picking up the phone.

That's pretty awesome. I would love to be able to activate that. Nice find!

I'm surprised this hasn't been found before and hacked to work as an ordinary led notification light.

If I didn't have a busted phone I would never have known. On android central someone else mentioned that the light will turn on when plugged in without enough battery to activate the led screen. Has anyone tried the notification light widget from Motorola? Supposedly that gets the moto g light to turn on. If that doesn't work then perhaps it is a kernel setting? I would love to play around to get this working but until my replacement arrives I'm stuck. The picture I took was dumb luck. I kept plugging it in until I could snap a picture fast enough with my nexus 5 to catch it. It looks really cool coming through that grill... Even if it is only green. Its more of a bar than just a single light but perhaps thats an effect of the metallic grill.

That looks awesome! I hope someone figures out how to enable it. I'm too stupid to figure that out :p

I love active notifications, but would still like using this for some things. It looks pretty awesome when lit as far as your pic shows.
Hard to believe it isn't controlled by the OS.

Yes someone found this early on in the Motos realease. It was eventually concluded that it is not in any part of the system framework so any kind of software changes wouldn't be able to enable it. It is independently attached to the batteries circuit.

Seriously... What an opportunity wasted... Especially since they put it in such a neat spot. To place an LED there in that spot in such a clever way and then never have it do anything with the OS seems like such a waste.

From the user manual:
Low Battery LED:
This LED lights up when you plug in your
charger and the smartphone’s battery level is too low to
power on the display. It means that your smartphone is
charging and will be ready to use shortly.

Seen some posts about this before and so far no one has been able to make use of it otherwise

Hah most of us haven't seen it because our battery life is so great :)

I've actually never had the motox run out of juice on me.

    first off you will need root secondly this only a command to trigger it

    adb shell

    su

    echo heartbeat >/sys/class/leds/charging/trigger

    echo battery-full >/sys/class/leds/charging/trigger
    Nice work figuring that out.
    Now, I can have an led turn on again when my phone is finished charging. Missed that from my old phone. Thanks!

    FYI, this is the fullpath (the other is a symlink):
    /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/charging/trigger

    I tested the other triggers, and here are my results:
    none
    -off
    mmc0
    - HDD activity
    rfkill0
    - didn't do anything for me, but it might light up when bluetooth is connected
    rfkill3
    - wifi connected
    - when I turned off wifi, the light went out, but it didn't go back on when I turned it back on - when I checked trigger file, rfkill3 was replaced by rfkill4, which worked the same way
    battery-charging
    - on while charging, off when charged
    battery-charging-or-full
    - on while charging/charged
    battery-charging-blink-full-solid
    - on when charged, but it didn't light up at all for me while charging
    usb-online
    - didn't do anything for me (thought it would work when usb connected)
    pm8921-dc-online
    - didn't do anything for me (thought it would work when connected to outlet)

    And we already know what heartbeat and battery-full do. Oh, it took a minute for the light to go on for the battery-charging triggers for some reason.
