LED Notification Light Not Working - Nexus 4 Q&A, Help & Troubleshooting

Does any else have a issue with their LED Notification Light not working?
No light when charging, or SMS, or Email, Missed Call, Low Battery... never lights up. Almost thought they forgot to install the LED until I used LightFlow to test it. And even then it only works when the screen is off, once the power button is pressed to turn the screen on then LED goes off, even though I set LightFlow to clear notification Manually. (LightFlow was just used to test if the LED was installed/functional.)
Uninstalled LightFlow, send myself a couple test emails and text(from another phone) and There was no LED notification light, just the notification sound.
Really hoping this is a software issues so I don't have to request a replacement device from Google...
Edit/Update: I'm pretty sure this is a software related issue and not hardware, as the LED is there and functions (with the help of 3rd party app, which we should not have to use) - So I'm trying to get a poll here of how many people have issues with the LED Notification light not working. Something to report to Google/Bug Report.

I believe the reason is that the software has not been updated to be completely compatible with 4.2+

What software are you referring too? LightFlow?
This topic has nothing to do with LightFlow...

Mine doesn't work either. I tried LightFlow and while it did light up the LED for some things, but not all that I selected, it was too faint to see, have to be in total darkness to see it.

The led isn't supposed to flash when the screen is on. Its been this way with every nexus.

But does your LED work when the screen is off? Mine and the OP's don't unless you use a third party app.

I don't know. I've had lightflow installed since first boot.

Is the Notification Light activated under display settings?

Mine worked, but not really well, I only saw it once when sending myself a test mail. Now I'm using Light Flow, which works nearly perfect (sometimes it doesn't seem to work until I enable the screen for a second and then disable it again)

Pulse notification light is checked

Im having the same problem. My led doesnt seem to come on no matter what. I know it worked out of the box because I have seen it light up with light flow but now im wondering if it quit completely and if I should do an RMA.

Mine has been working fine. It's white for TXT's, green for a lot of other things like FB and whatsapp

Yes the "Pulse notification light" option is checked.
I woke today with 6 New emails, 4 text messages, and 1 missed call... No LED Notification light was on, blinking or doing anything.
There not being a notification light is bugging the heck out me, 'cause I depend on them when my phone is on silent at work so I'm able to know there is a message waiting without having to stop what Im doing to turn the screen on every 5 min.

Try 'Blink'
Try the app 'Blink' very simple and its works for my N4

are you waiting 10 seconds before turning the phone on? Thats how long it takes before it blinks again. Whoever programmed the LED truly hates LED notifications because he made it blink so slowly and dimly that nobody could possibly notice it.

Yup, sat there watching the phone for a good 2-3 min after hearing the Notification sound for new email / text. (screen off)
Not sure if its suppose to or not, but I don't even get a LED Notification light when the phone is charging or charged (have to turn phone on to check if the phone is done charging.) Past devices I've had used the LED to notify of charging/charged.

It's normal that it doesn't glow when charging. I really can recommend Light Flow, then you can customise the notification as you wish (the free version is good, I bought the full version because I need steam support, but for normal use there is no need to buy it)

Ok, so my notification light wouldnt work no matter what. I uninstalled sms popup and now light flow works like it should. I guess the sms popup was somehow blocking light flow from allowing it to activate.

No notification light shows while charging, hence why when you charge the phone when it's off, it shows an animation on the screen. It should for calls, texts, emails, etc. though. Mine works. It even shows blue for facebook and white for texts/emails. Not sure why it wouldn't work. Have you gotten the 4.2.1 update?
Additionally, light flow states in its description that it doesn't work on most lg phones.

The impact on battery life should be absolutely minimal. It blinks when a application sent a notification with a LED-request to the phone. Usually, you can turn this off in the application in question.
For example, Gmail lets the LED blink green when a new E-mail was recieved, Twidryod lets it blink blue. In both programs, you can deactivate the LED-notification in the settings of the program.
None of my apps (incl gmail) have any LED options, and I've never seen the LED flash at all. Not for calls, sms, email or anything.
Could be under sound, pulse notification light?

Green LED light staying on... can't figure out why

I (of course) do not have root, but I am running light flow. It seems to be working fine, the LEDs that should go on are working and in the proper colors.
I have unchecked all the LED notifications under settings.
However, when I turn my phone off, the green LED light goes on immediately. It is not plugged in, and it's down to around 92% battery or so.
I even tried disabling all charging/battery related LEDs but still the green LED is on.
Anyone else having this? Any thoughts?
Light Flow is known to cause problems on the S3.

And I was wanting to download and use that.
Yes, I see after further testing that uninstalling light flow fixes the issue. Dangit, it appears light flow is far and away the best LED app. I put a note in feedback about it, hopefully the dev will be able to solve it. I'll try it again once we have root for the US version.
Any know if the light flow creator is working on this?
It's listed in the known issues on the developer's site, so I assume they are working on it:
hxxp://www.folioflow.com/ff/page/website/lightflow/pageId/1931
it has something to do with interactions with the built in notifications.. if you disable them then light flo doesnt work.. if you turn them on then whenever the phone goes to sleep a green light comes on.. bummer
i used the LED color tester app and all the LEDs colors are off from what the previous commands were, i guess... so its going to be a while until the led programs work properly

Question regarding notifications and the display

On previous phones, when I got a notification, say a text message, the screen would light up and I could tell I had to check my phone. On my N4, when I get a text the phone only vibrates and the screen doesn't light up. Is there a way to have it light up? I tried looking through all the settings but couldn't find anything, and I find it rather odd LG would set their phone up like this.
Also- is there a way so that the pulse notification light goes off more frequently? right now I have to wait about 10 seconds for the next pulse light to go off, making the notification LED rather useless if i miss it the first time.
Thanks.

There's custom ROMs such as CarbonROM, Xylon, ParanoidAndroid, or XenonHD and so many others) that let you configure the colour, blink rate, and application-specificity of your LED indicator. You can also look at Liteflow to customize your LED notification if you'd rather not go to custom ROMs

This. But if you are rooted and having a custom ROM, they integrate it by default. But if it's really waking up the device you want, you might want to try an app called SMS WakeUp. (You can get it from the Play Store)

Best app to control notification light?

Just got my nexus today! Playing with the notification light and doing some research. Seems light flow and led blinker cause the ambient display to come on randomly. I also tried light manager but that gives a persistent notification in the notification shade which is annoying. Any suggestions?

light flow works great for me (I turned off ambient display, as it doesnt work very well even without light flow installed). You can also, in light flow, turn off the switch screen option, which will also help with ambient display.
as for the persistent notification, that is a marshmallow issue for the time being, the light flow developer explained it quite nicely (ill try and dig it up).

Yeah, I mean I just got the phone today but ambient display is a little wonky. I thought it was supposed to turn on every time I take my phone out of my pocket, but if doesn't.
But where is this screen option in light flow?
The persistent notification is only with light manager. I don't get one with light flow.

give it time, on its own, it will come on also
In light flow, I am not sure if it is on by default, but if you go to main settings > general settings, there is an option for device admin, if that is checked, you will also have an option to switch screen on (which you can enable/disable on a per notification basis) . You could if you wish use this option instead of light flow, it may work better for what you like as well.

Notification LED Times Out After Only 5 Minutes?

I've observed that when an incoming call rings the phone and it is not answered, the green notification LED only flashes for approximately 5 minutes before it times out. I'm used to a continuous notification light on my Galaxy S6 and Sony Z3 until I unlock my phone and clear the notification.
Would be nice if we could change this default behavior. I much prefer a continuous notification light vs. one that times out so quickly. Unless you use an app similar to DynamicNotifications, you may be checking your phone a lot just to see if you've missed any calls.
I haven't tried any other notification tests from other apps. Can anyone else confirm the behavior described above?

True I have the same I don't think is something we can do about it, I tried some apps but the led color doesn't change.

Dont think its a multicolour LED.
Anyone figured out to have the notification light remain blinking until unlock of the phone???

Hmmm...I wonder why an LED if you can't really work with it. I use LIghtflow, and would hope it would work on this phone. Maybe it won't.
