Notification LED doesn't flash

The new message notification LED on my (new) LTE Gnex only flashes once or twice, just when the phone boots up. Doesn't flash when a new message arrives. I've tried disabling it, and re-enabling it in settings, but it just does not work. This does not seem normal, and I'm wondering if I need to return the phone, which I really don't want to do. I've already unlocked the bootloader and rooted, but still running the stock ROM.

Have you tried Light Flow from the Market?
This has worked with the stock ROM.
I personally use Trackball Alert Pro - MoDaCo ROM has suppport for this.

Just tried calling myself, and hung up. The LED isn't lighting up. But I have seen it blink for emails at least. Hmm.. maybe try light flow.

Have not tried any 3rd party apps, yet. First I wanted to know if there was a problem with my phone, or if this is "just" a bug. If others have this same problem, then I'll try a 3rd party solution. Thanks for the feedback.

Tried the same thing, called myself and sent messages with no led notification. Thought my led was broken but then installed light flow and it worked no problems.
Not sure how it was supposed to work stock but could not get it to work at all without a 3rd party app.
Without the app, the only option I could fight was pulse notifications which I tried turning on and rebooting but it never seemed to work.

Just tried light flow. When I tried the "test LED" function, my phone would no wake from sleep. Also got sleep of death when I got an email. Had to do a battery pull. Any solution for this?
I looked at Trackball Alert and it requires Paul's ROM, which I'm not ready to try (yet).

I noticed it doesn't light up when it's charging either. Is this normal behavior?

From what I've seen so far the stock light is a hit and miss for me. Only time will tell how they will improve this.

Do you have it set on? Lol that's all I can think of. Mine works fine

Well its not your phone....The light stock is stupid I have no idea why you would include a light that only flashes random times and only in white..... I had issues with lightflow crashing my phone when waking with several notifications flashing. Just bite the bullet an flash ARHD or Paul's rom they both support Trackball notification and it works very well!!

Yep. Probably don't have/use most apps that support it for me to notice it all the time.

I've been having the same trouble. Haven't seen the light in days.
I went back and revisited some of my settings. I had turned on the setting for the screen to "stay awake while charging." I unchecked it, and now my light is working again.
Now, it only ever comes on when the screen is off to begin with. It won't come on if the notification happens while it's already on.
But at least the light comes on when the screen is off now!
(And I really wish the blink rate was higher. You can look at it for several seconds between blinks, and think there's nothing and look away.)

So the change I made to the settings seems to have fixed the light issue. I have been properly getting notifications since I turned off the keep awake. Seems like an easy enough to fix bug as long as they know about it.
But now what I want is a faster blink rate. One second on out of every 6 or 7 seconds is easy to miss.

[BUG] Sometimes the led doesn´t blink

Hi, I have noticed that sometimes when I have a notification, the led doesn´t blink at all, and sometimes it does. I have official IMM76I, and I have noticed it mainly with Whatsapp, but it can be because is the only program I use with the phone silenced in my work.
Have you noticed that?

Where are we talking of color option?

I have noticed it even with GTalk and many other apps. Yesterday, I was playing when a notification sounded. Without turning on the screen, I kept watching the phone but the LED never blinked. I turned on the screen and I had a GTalk message.
Nothing else have noticed that problem?

I have had this problem as well on my VZW nexus on AOKP m5 and earlier versions as well. It doesn't happen all of the time, but maybe 10-15% of the time with SMS and at least 90% of the time with gmail.
I can see a gmail come in on the notification light on my Xoom, but nothing happens on my phone, I'll check the phone 5 min later and the email is there but no notification.

You mean there is not the notification icon on the upper bar?
My problem is different, I have the notification icon, but the led doesn´t blink

Notices this as well with various apps. Native as well as 3rd party. Doesn't bother me that much just makes the OS less 'perfect'.

Thanks for the idea, I have not tried the light flow app; but I have asked in another forums and people with than app also have noticed the problem.
Anyway, the objetive is to find the bug and report it to google, so they can fix it in the next update for our Gnex

Anyone else with the problem?

Is the option checked in each program? Those who flash rooms and rebuild everything might forget an app or two that does not have the option on by default.
Sent from my Galaxy Nexus using XDA

I've noticed from time to time as well... But the other thing is that even when it does blink, it often shuts off fairly shortly afterwards.
It would be nice if there was options to ensure that it blinks and keeps blinking until you acknowledge it.

Light Flow works perfectly for me. Never had an issue with it not blinking or blinking incorrectly.
I use it as not all the apps I have on my phone have LED light functionality natively, and Light Flow takes care of that.

Yes, because the problem is not always, and the same app can work, and not work sometimes..

In first app u can set time flashing, how long should be flashing and even it wont solve you problem, that second app will turn on your screen for a while and it turn led flashing corectly, some roms has issue that led doest work when is screen off. But i think second app solve you only sms flashing, missed calls not. Try fist, I had it and work properly.
EDIT: First app is for everything....missed cals, email, facebook etc.

Light Flow issue

Hi guys, i'm having some troubles with Light Flow and KitKat on my Nexus 4.
I have set the led notification color etc.. but when there are notifications the led doesn't pulse.
I also try the testing mode of any notification and the led doesn't pulse but the led works..
Someone else has this problem? solutions?

I dont have any issue on my nexus...and you're wrong forum section..it should be on QA and Answer..

Same thing happens on my N4 with the paid version on stock rooted KitKat. I did a LED test in Light Flow to make sure everything works and it does, but the LED lights up about 20-30 seconds after I begin the test.
I then tried the free version of LEDBlinker and the LED lights instantly during the LED test and actual notifications.

No problem, at all.
Light flow works like a charm to me.
Stock, rooted, clean install of 4.4.

I have a problem on KitKat it notifies me but sometime a notification isn't dismissed from the app so the led just keeps flashing. Its annoying but as KitKat is new it'll hopefully be fixed.

I have a issue with lightflow too .. sometime the led is working like a charm, then sometime (like 20% of time when i got a notification) nothing happen, i mean there is no led notification AT ALL !
Didn't try LEDBlinker because i like light flow for its feature to open screen for 5 second when a notification income

I have the issue where if I want read a text message after my screen is turned off then the light blink continues to go off. Its really annoying

I had also wait a bit to see if the led was pulsing, but now it doesn't works..
I couldn't find anything on internet so I thought it was only a my problem..

Make sure to turn the accessibility service on and tick the notification access. (Security->Notification Access.)
Works perfectly fine for me, haven't had any issues with Lightflow on KK.

Try using Light Flow in "Foreground Mode" (No idea what the setting is called in English - i'm using localization), it sometimes gets killed by Android to free up ressources for other apps.

There's a new update out that has a few fixes for Kit Kat. The long delay of LED notification was fixed on my phone and all my custom settings react instantly.

The same happened to me, I found a temporary fix for that specific issue, though. If you go into the Lightflow there should be an option called like "Hangouts - All Notifications" or something like that, enable that one and the LED should start working again when you get an SMS in Hangouts.

The update isn't perfect... Sometimes it fails in SMS, but i think it will b just fine in the next couple updates, it's a very good app.

Maybe there is dust...try to open phone i clean it from inside

[Q] Led Notifications not working

Received the M8 a few days ago and the LED works OK as it lights up on charging...BUT that's it no missed call or Email SMS etc.
Looking around various forums it looks like there are some issues probably software related as people have exchanged phones and still had the issue.
My question to you on the International version is anyone having these issues and if so has anyone found a fix.
Thank you

I had the same issue; so I factory reset the phone. But this time around, I didn't restore any backup and started fresh. Seems to be working so far (and it's been 2 days).

Can confirm this method works but should'nt have had to factory reset. I'm now resetting up all my phone . .just hope it doesnt happen again.
Must be back from google bug somewhere that messes up the LED's from working ?? But dont really understand how it would . .

I had the same problem. I read on another forum that if you install another launcher the led stops working for notifications. When I first setup my phone restored apps and one of them happened to be a launcher. I did factory reset did not restore any apps and notifications led started working again. I'm not sure if another launcher had anything to do with it but the fix worked for me.

For me the notification LED works from day one, did not had a problem, i did restore my apps from backup but i never used any other launcher so i cannot confirm that is the problem. But i believe it must be app related as its working for some and not for others, usually hard reset without restoring app brings it back. Strange...

When I was migrating my note 2 to m8 must have copied a new launcher . I have factory reset and installed backups manually all is good now

Everything I found says that there is no setting on the phone to change that. It may require a developer to patch it or give us some instructions on how to extend the time.

I'm also having the same problem with the LED notification. I really don't want to do a factory reset so i'm still hoping that there is a solution to this. The LED lights up during charging but does not light up at all for text message or email or other notifications. I'm using nova launcher so some are saying that it is because of these third party launchers that is the cause but i'm still wondering how can that really effect the LED. I hope somebody can really enlighten us on this.

I had this issue but only for missed calls. Other missed things would still notify. I did a factory reset and still have the same problem without doing any backups!!

I have the same Issue but I really don't want to reset the phone.
Still hoping for another fix....

I had the same problem on the day I picked it up. Read about the factory reset and as it was my first day with it decided to go for it.
That did indeed fix it and the led started working as it should..... Today however, they have stopped again. I haven't installed any other apps and a power cycle doesn't help.
Don't want to reset it again so am hoping they fix this soon.

Any news on this? Really missing led notification

I installed Light Manager and i seem to be getting lights, however im getting random notifications with a vibrate and light when there is in fact no notification.

Mine seem to come and go, they worked after the factory reset for a bit I then noticed that they had stopped .
Now they are working again.... Seems very strange.

Notification LED only works if your screen is off. The LED for charging will illuminate no matter if screen is off or on
