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.

Thank you for the feedback. This is exactly the same behavior that I am seeing.

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

Yes, mine is enabled.

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!!

I don't think these two have a CDMA/LTE ROM yet, do they?

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.

4.1.1 and lightflow

So i got my 4.1.1 update yesterday and ever since then my notification LED stopped working all together.
I uninstalled lightflow and my LED is back again.
Just wondered if it works for everyone else still before i bother to reinstall and set it all back up.
Cheers for replies

The dev of that app is working on jelly bean issues. He is aware of it.

Ah nice one.
thanks for the reply mate. Ill keep an eye out for updates.

Known Issues
Jelly Bean not yet clearing notifications
The accessibility service doesn't seem to be running in Jelly bean causing issues. I'm looking into it. Going into phone settings, accessibility and switching lightflow off and back on again sometimes helps.

I see that I can't access to light flow notifications (where I set my preferences) but it runs... I hope in an update very soon!

Lightflow doesn't seem to be working on Jellybean yet, it mentions that he's working on that still on the app page. Can't get it to act properly for me either.
Aaaaand my response is a bit goofy looking being made right after the same thing!

Damn its amazing how much you can miss the little things. This stock LED is driving me crazy

Now I realize how important LightFlow is to me!
Thanks in advance for resolving this problem.

Don't notice it till its gone. Patiently waiting for the update. Bought the paid app I'm sure he's working hard.

Lets keep each other updated on the status of the fix.

after disabling the app and service and re-enabling both, most all my notifications seems to be working fine for the last 24 hours or so. the only one that doesn't work is the sms/mms notification, but i'm using sms popup and i don't recall it ever working with that app enabled previously on ICS.
most everything clears fine as well by either swiping the notification away or closing all notifications with the 'close all' notification bar icon. the two exceptions to this seems to be wordfeud and plume (twitter) which i have to actually open the apps for the notification to clear.
i'm currently using lightflow to notify me of:
gmail
sms/mms
plume (twitter)
friendcaster (facebook)
missed calls
wordfeud
battery 100%
google voice
parcels (package tracking)**
** i haven't confirmed working yet
update : google voice is working. just got a call and a vm. both my missed call and google voice notifications are cycling.

I have noticed that if i restart the phone Lightflow needs to be manually started to get it to work...after you launch the app it does work properly..patiently waiting..wicked app

"Jelly Bean not yet clearing notifications
The accessibility service doesn't seem to be running in Jelly bean causing issues. I now seem to have a fix that works for this, which I expect to release in the next couple of days after a little more testing."
The accessability service is the heart of Lightflow, when it stops all bets are off.
I'm sure they'll release the fix soon and all will be well again in jelly land

looks like theres an update! a review (play store review) said it now works on jellybean.

I tested. Doesn't work. App crashes..and now I'm stuck with it until a fix..lol. sux.

Updated. Preliminarily it seems to be working fine now. Haven't tested a ton yet though.

which kernels are you guys using? I have noticed that some kernels stop my led altogether. I'd like to give it a shot but I have yet to have it work for me on 4.1.1

Yessssssss! It works! I'm happy. Thanks Dev!!
I'm on stockrom, unrooted.

LED Notification Issues

The LED notification on my Verizon Galaxy Nexus is shaky at best.
I mainly get notifications for Gmail and Google Voice texts. It seems as if it only sometimes actually work. It seems worse for the Gmail notifications, but there are many times that I pick up my phone and see that I have an email when there is no LED blinking.
I'm not sure if it just never came on or if it stops after a period of time, but what the heck is up with the LED? Why bother putting something on the phone as a feature and not having it work correctly.
I'm currently on a custom JB ROM, but it has only worked very inconsistently at stock on ICS and any of the other ROMs I've tried.
**** And yes, I know about Lightflow, but don't think we should have to use a 3rd party app to enable something that should already be working.

I am very new to my galaxy nexus but I've noticed that the LED basically only blinks for GT/whatsapp messages while for other apps/missed calls/sms it only blinks once at its very best, that's why I kind of forced myself to use lightflow. There are some custom JB roms like Liquid Jelly Bean that offer advanced LED management, you might want to try those.

I think I also read that the free version of LightFlow doesn't support Google Voice which is one of the main 2 notifications I get.
It's just very surprising that this feature of the phone works so poorly. And even more surprising that there aren't more people making noise about it.

I had the same problem, and I still think that LED notification isn't as good as what it should be...
If you have a custom JB ROM, I think your best option is to look for a CM10 rom, because in the screen settings, you can change the behaviour of the LED with different apps.

[APP] Light Flow

the developer has claimed the latest version on the play store is working for rooted phones, but I still am not having the best of success. I thought I'd start a thread and see how others are fairing.
The newest version has some improvement; being able to select different colors for different notifications and actually getting them to go off when you've pulled down the notification bar. however, it doesn't blink for me at all. When i get a text or email the corresponding light is a steady constant light if the screen is asleep. If you wake it up the light either disappears or only lights up very infrequently.
I've read some posts before the latest versions came out that some users had success getting it to work by actually turning Accessibility off. This seems to turn off the entire app for me.
anyone having better luck?

I have had the current version working correctly both on a stock TW rom, and now on CM10. The flashing lights haven't been implemented yet, however he is working on it.
The only thing I had to do on the Samsung TW rom was disable Samsung TTS in the manage apps settings. Once I set it to S3 root mode, everything worked perfectly.
I suggest you follow his blog here:http://www.folioflow.com/ff/page/website/lightflow/pageId/1826

I have done all that including following the developers blog. I have accessibility on, only have the light flow notifications turned on, allowed SU access to light flow app, and have tinkered around with it all weekend but it still isn't working correctly. It works fine when the screen is on, but when the screen is off it gives a solid light.

Its not supposed to blink get, that's why I linked you to his blog.

A blinking light will kill the battery or at least use more juice. Dev did say he is looking into that feature tho

Developer advises blinking uses more battery than solid notification. Go figure.

Since I installed Light Flow, whenever the screen is off the LED glows a faint green. First I disabled Light Flow and the led still glows green. I unchecked it under Accessibility and rebooted, still green. Just had to uninstall and reboot to get it to stop. Anyone else have this issue? Is there a setting I'm missing somewhere?

I had that issue when I restored from an old version of light flow. The newest version that I installed straight from the Play Store works fine.

I believe to get other colors other than green, you need to be rooted and go into the app settings and check "S3 root mode" or whatever its called...
Works perfect for me.
EDIT: I think the updated app (as of today) should work whether your rooted or not.

The update version today also supports blinking in adjustable intervals.

You guys should just install cm10 on your phones, it already comes with notification light settings & it works perfectly :good:

I would agree with that almost fully except it's a pain setting up different notification sounds between e-mail and sms/mms. It's also nice to be able to have it make notifications at intervals from missed calls/sms and the light to go away eventually if you want.
But I do have to say, I'm on CM10 - Paranoid Android ROM(latest build) and light flow is working like a charm for me right now. Looks like the bugs have been worked out for the most part.

Hi guys.. I have an international S3 and since a recent Lightflow update, I regularly get lightflow causing wakelock for hours. even with no outstanding notifications. I've uninstalled, re-installed - same problem.
Happened 3 times this week. reboot fixes it.

Trouble getting light flow to work properly

I had light flow working fine, then I flashed an update with FlashFire and now I cant get light flow or any other notification light app to work at all, The light itself will work with the stock notifications but light flow does nothing, the light flow widget will show me it see's the notification and all that stuff but it will not turn the light on., if I test it in the app I get a quick split second flash but thats it.... I tested it on my wife's phone which has the same build of android on it (but non-rooted) and it all works fine... and if I restore an old backup the app works fine.... I even tried a factory reset after updating with flashfire to make sure it was not any other app conflicting with it and it still wont work.... it seems to be something to due with using FlashFire.... makes no sense.... anyone have this trouble? or anyone have any ideas on what may be going on????
