Notification LED light does not work AT ALL, EVER!

My Verizon Galaxy Nexus does not seem to even include a notification light. Although I see and read about a notification bottom middle of the front of the phone. Mine simply does not work at all and never has. Anyone know of this issue and may offer advice? I have downloaded light flow lite and have had no success, also downloaded LED tester apps and it still doesn't work. Please help.

Have you turned on the notification light in settings? Settings > Display > Pulse Notification Light

Yes.

Play Store > Light Flow > Your welcome

I have already installed light flow. Still not notification LED ever. I have had test SMS sent over and over with no response from the LED. Pulse notification light set, light flow set ON in accessability. All software is set to turn the LED on, the light itself is just not lighting up..

PLEASE HELP
Is it possible Verizon my only option here?

As a test, download an app called "Galaxy Nexus Led" from the market
Enable it and then plug ur charger and turn ur screen off
I think the Nexus's led only works when the screen is off

Take it to VZW and request a new device for the LED not working. You're not the first person I've seen with the issue, and you probably won't be the last to have the problem either.

I've had the same LED-Error... but i solved it.
At first... I'm shure that your LED is not broken. Cause... it is a LED
Before you read the rest of my message, check if you REALY activate your LED in the PhoneSettings and in any app you've allowed to controll the LED. If you're using LightFlow don't forget to activate it in the "Device-Admin-Settings" of your Phone.
Now try a test...
If your LED is not working ... format your cache and dalvicCache partition ... afterwards, it MUST work.

[Q] Light flow/LED problem

I just switched from a Nexus 4 to a HTC One M8 GPe. On the Nexus 4 I used Light flow very much with many colors and blink patterns to be able to identify what was happening without turning on the screen. Now when I have installed Light flow on my M8 it's only possible to choose from 4 colors or something and no blink patterns.
Is this possible to fix?
Great phone but this really bothers me...

Someone can correct me if I'm wrong, but I believe that it is due to the limitations of the LED on the M8 vs the N4. It's a different type of LED so there isn't an ability to tinker with it as much.
I miss that from my N4 too, but ultimately as soon as I saw/see a notification light I check the phone anyway.

I suspected this but before I got the M8 I didn't even realize that it would have anything else than the best LED. But yeah, 90% of the times It's just a message of some kind so I guess I'll survive. Still annoying though...

Not only is it not possible to fix because of the limitation of the LED that the other poster mentioned, but I'd be shocked if Light Flow gives you any color other than green and if it works consistently.
I had messed around with it some a couple of weeks ago, and gave up. I guess it's possible the Light Flow developer has tweaked it since then, but the version I was using was pretty useless on the M8. I don't fault the Light Flow developer though. I blame HTC on this one.

I was able to get green and amber to work. Some colors would just pick green or amber, others just wouldn't do anything.

Yeah, it seems to work pretty bad. Are there any other ways to control the LED like Light flow? Does it work better if you just let all the apps control it themselves? I guess not?

I was able to get green and amber to work.

Green, deep orange, magenta and cyan works for me, but green and cyan shows as green/yellow on the LED and deep orange and magenta shows as orange.

Messed around with the LED settings in Textra after I disabled Light flow and suddenly it actually started to blink. Great improvement!
Is it possible to get it to blink in Light flow too?
Edit: Yes, enable color mixing.

Maybe I was unclear. To get it to flash in light flow you just need to enable mix and choose flash under the right color. This is not specific for Textra, but Textra can flash the Led by itself, without Light flow.

I've really tried getting it to work, but needed to put it in Direct Mode to get the LED with permanent light when lit, instead of flashing.
But in this mode the LED is dimmed even though the settings are set to 100% brightness in lightflow.
To get the LED 100% brightness I needed to remove Direct Mode and accept that permanent light instead didn't work, and live with flashing LED. Hence, not very different control than the standard setup i the Sense rom.
Any clues?

Try direct mode, root mode and HTC alternative mode. All three at once.

With that Setting the led is always permanent on dimmed like 20% through mixer and also standard control.

Yes, I had the LED flashing green from Textra, without Lightflow. But the Textra reminder options are so limited, I'd really prefer to use Lightflow if I can get it working properly.

Then I dont know. Works perfect for me. Really bright too. Have you turned off LED notification in screen settings?

I've been fooling around with this a lot since hearing the news that it was working.
I think I've got it working pretty well to my satisfaction now. As I was messing with settings, some of which I may have inadvertently checked (like the Samsung always on setting) I saw a number of interesting behaviors.
One was that at one point my basic notification was, instead of just the green LED flashing, a combination of alternating green and amber colors. (I'm not sure what I did, so don't ask me to reproduce it.)
At some other point I had the LED staying on even with the screen on.
There were other issues, though, when those things were happening. So I kept monkeying with the settings, and I think while neither of those things are happening now, for the most part Lightflow is working acceptably well. I actually would like it if the LED --could-- be on while the screen is on.
Also unless I am mistaken, after an alert, if the screen is turned on but the alert is not cleared, when the screen is turned off, the LED will not come back on. Is this what you two are experiencing as well? I'm pretty sure with my last phone if the alert was not cleared, the LED would continue to flash.
Thanks.

When the LED is alternating between two colors (or more on other phones) it's probably two (or more) notifications and you've got the settings to loop through them all. Standard setting is to do this when you have the charger plugged in IIRC.
The LED is working with the screen on for me and I think it always has on the M8. On my Nexus 4 it turns off when I turn on the screen and the LED turns on again if I don't clear it and turn off the screen. Great if you don't want to read the message right now and still don't want to miss it later. Since the LED is always working wether or not the screen is on, this is not a problem on the M8.
But if it's possible to alternate with both colors on the same notification, that would be a great way to get a third "color". Could you check if it is like I said or if it really is dual color?
EDIT:
I got it to work! In mixer you can set one color to solid and one to flash to get both. So there are actually a difference on green + amber and amber + green. This will give us a total of 6 options: green, flashing green, orange, flashing orange, orange + flashing green, green + flashing orange.
EDIT2:
The non-flashing color isn't very strong, so I'm not sure how useful this really is.

It was definitely not really two notifications, though it is somehow possible that Lightflow was acting as if it were. The alternating was definitely like the alternating LED colors that I used to see on my last device when it was alternating between notifications.
I can't reproduce it because I don't know what crazy combination of settings I had at the time. The Samsung always on setting was probably involved. It's even possible I had incorrect checked the Samsung root mode. I was really trying lots of things, and not sure of what I was doing.
Right now, as you suggested, I have Direct Mode, Root Mode, and HTC Alternative driect mode all checked.
I have all LED notifications turned off in Settings/Display and Gestures/Notification Light.
I have Textra set to not notify me in any way, and am using LighFlow for notifications and repeat notifications.
I have not tested things much, so I really don't know how well it is working, but it basically seems to be, though I definitely do not have the LED staying lit with the phone on, or after I turn it on and then back off.
I wonder if some of the differences we are seeing could be due to versions of the phone, rooting procedures, etc. My phone is the Verizon version, and I used Weaksauce to gain root access. Could this make a difference?
Again, many thanks!

It is not possible to fix because of the limitation of the LED.

LED notification

Hey guys,
I just wanted to check if Moto Z play has LED notification. I just read somewhere that this device does not have one. But wanted to confirm.
If this is true, I have to look for another device.
Thanks

No doesn't have notification light more a on screen notification , like if a gumtree message comes through and the screen is off It shows a tree in a dim white at the bottom

It actually has a hidden LED as every moto device. On CyanogenMod I've already repurposed it as notification LED.

If it's like the Droid Turbo it has a "charging LED" that can be used with root

If u root there's a app that can make the front flash work as a notification

Thank you guys for sharing the information

I saw the LED on our Moto Z play, when you connect the turbocharger with the phone turned off, you can clearly see a white led (not the flash) blinking briefly in the zone of the proximity sensors.

Yeah there is something between the front camera and speaker, maybe someone can configure it for notification

I used led control app to make it work. It is only white. And it didn't make it work for notifications. Only when charging, or usb, or using internal, or external memory.

Tasker is capable of using this LED and you can set it up to function as a notification light. I do it with my Droid Turbo.

This may or may not work on the Z Play. You will need root.
BACKUP FIRST JUST IN CASE!
I have it setup to only turn on if the screen is off.
Task 1 (LED on): if %SCREEN ~ Off
Set light - set charging to 1
End if
Task 2 (LED off): set light - set charging to 0
For profiles do this for each app you want to have set off the LED if you don't want it going off for every notification. Otherwise don't choose an application and it'll go off for any notification:
event > UI > notification. Choose an application (optional) then have this profile perform Task 1.
To turn off the LED I have it go off when I turn the screen on.
Event > display > display on and have this perform Task 2.
I'm sure this can be improved but this is how I have it set up right now.

I saw the notification light as well and enabled it via e x kernel manager apk.
Your suggestion and instructions was spot on.

Works great!!!

I watched the videos. It almost appears the LED blinks in the 2nd video. But am I correct in saying the notification LED does not blink?

How did you enable it using EX kernel manager?

I've tried this. It doesn't blink. Within the software, the Charging LED doesn't have a blink option, only solid.
I'd personally set the LED to only be on when I've missed a call or text since I don't care about emails.

Yes, I remember it being the same way on the G7 Power, and then I found out that it had a LED by installing one of the custom roms which had taken the time to add some custom features allowing full control of it. If it can be solid, it can also blink, it's just a matter of programming it that way, perhaps a developer could figure it out.

Status LED - for notifications?

Hi, could any one tell me if the charging LED also works as a notification light? Cheers.

Yes, notification led works when charging. When battery became full charged, then led turns off.

Hi thanks for that - I don't think I worded it right
Does the led does function as a notification light? (as well as a charging light)
Cheers

Yes, LED works also for notifications, but it is almost invisible. One must check the phone at specific angle to see the led.
