LED notification not working any more

I've just realized my notification LED doesn't light up anymore regardless of what the notification is.
I thought it was the lightflow app affecting it so i did an uninstall and rebooted my phone, but the LED still never lit up. What gives?
I'm running stock 4.0.2 unrooted device.
EDIT: Even going into GO SMS Pro and under Test Notification the LED also doesnt light up when it normally does.
EDIT 2: Just reinstalled light flow, re-did all my settings, and then testing the notifications via lightflow doesnt work either. My LED just stays blank. Is this normal?

Make sure it's turned on in Settings > Display > Flash Notification Light...

I, too, have consistently had this problem. The only ROM I've been able to get LED notification working with consistently is CM9, but even that has been giving me trouble with the latest nightly.

Did you install an app in between the time it worked and the time it stopped working? If so, try uninstalling it. I've had a time or two on ICS where I've had 3rd party apps conflicting with different things. One time I installed Tweetdeck and it completely killed GPS, couldn't get a lock or anything. I uninstalled Tweetdeck, and GPS came back. Reinstalled, and haven't had a problem since.
Probably unrelated, but technically ICS is still Beta in many ways.

I've done quite a few things in trying to narrow down the problem, including wiping data, trying different kernels and varying ROMs, and uninstalling any apps that control LED notifications in any way. Nothing has been able to get my LEDs working, except restoring to an older CM9 nightly.

Sounds like there might be something in /system that is preventing LED notifications from working in the newest nightly. I haven't tried CM9 yet, or I'd test it as well to see if it's an issue with the latest nightlies.

Solved!
It would seem that the newly merged Quiet Hours code includes an option to disable LED notifications as well. It's set for the whole day and is on by default. It's under Settings -> Sounds. Once you disable quiet hours, LED notification works as expected lol.

[Q] Is the notification LED on your Note II working reliably?

Being an ex-Galaxy S1 and Galaxy S2 owner I was happy to finally have a notification LED on my phone. However I have found that the behaviour of the LED just isn't reliable.
When I got it a week ago it worked, then it stopped working for no reason, then it worked again, then stopped, now it works sometimes but most it just doesn't. I find the behaviour to be quite erratic and difficult to diagnose.
I tried using both the stock LED code and LightFlow (exclusively and at the same time) but both exhibit the same erratic sometimes-works-sometimes-doesn't behaviour. Totally unreliable.
This has happened with my original 4.1.1 ROM (stock, unrooted), then 4.1.1 rooted, then 4.1.2 stock unrooted and now I'm on stock 4.1.2 rooted. No different. Sometimes it works, most times it doesn't.
Is your Note II notification LED reliable? Searching got me some threads on LED trouble (both for SGS3 and Note2), but no conclusive reasons/solutions.
PS: I checked the LED with the factory test code and it works perfectly there - it does not appear to be a hardware issue at all.

It works for me all time. Very reliable I'd say. And I'm a person who hates any sort of non working things. Like Smart Alert, which has literally stopped working for me. And like you, it works each time perfectly on test mode.
PS: I switched to LED Light Manager last week, but that doesn't mean the stock LED didn't work.

My native LED works fine but it's pretty limited. Better than nothing. I like Lightflow the best but it interferes with/invokes the Note II Accessibility functions so I removed it until they are worked out. Light Manager seems to work but the only thing I don't like about it, that Lightflow has, is the ability to flash network status when you have good signal (i.e. green flashing LED when you have signal; Lightflow does but LM does not have this function).
Ideally I just want an LED manager to mimic Blackberry, flashing green in standby mode, and flashing red when "something comes in". I have no need for 18,000,000 color combos.
Cheers

I haven't had any issues with my LED notification light. It has always worked for me. I don't use any apps though. The most I do is go into an app and select the color I want the LED to flash. But that's already built into the app. But they stay on while my screen is off. If it's flashing, and I turn on my screen, then I believe they disappear. But to be honest, if it flashes and I turn on my phone, I usually check the messages, reply to them, or clear them / swipe them away.

So despite all the problem threads I found, 3 users with no issues at all, interesting.
I can understand that as for the first days the LED behaviour was accurate, but since then it has been quite randomish and I have been unable to find a pattern. Somtimes I have a missing call and have the LED blinking, sometimes I have a missing call and nothing happens. There is no easy difference between the two situations.
I will try LED Light Manager, never used it and one more shot won't hurt. Meanwhile I was starting to think that the LED unreliability was the reason why 99.9% of all Galaxy Note II covers designers don't bother to add a LED cutout. :laugh:

Mine has been reliable so far.

The notification LED on my Note II has been very reliable, unlike on a past HTC phone where the light would either not blink or would not stop blinking.

All of my led are working fine
n7100
omega rom v10 perseus kernel 31
hit thanks its free anyway

It's working properly on my N7100 also.
No problems at all.
Now for the solution:-
1.You can try reflashing a rom (stock or custom)
2. Install ths.
https://play.google.com/store/apps/details?id=com.koo.lightmanager&feature=search_result
This should override the stock LED functions and may improve it's performance.

No issues what so ever with the LED, I've never used custom roms/kernels on my phone though.

I'm even more puzzled than before now, as I cannot find a reason for the erratic behaviour on my phone.

Did you read my post and try my method?

Yes, I already had Light Manager. I also have LightFlow, but first started using teh samsung notifications only.
I find the same pattern in them all... sometimes teh notifications trigger/clean properly, some times they don't. Usually they don't.
I tried several combinations, Samsung LED app only, Lightflow off, Light Manager off, etc. And the same remains. The behaviour is erratic. Seen other users complaining about this in other foruns, but since it seems tricky to reproduce, no solution is clear.
I'l on 4.1.2 stock (bot rooted now) and besides de rooting my phone has almost no customization at all. Going for a full wipe/reset seems overkill, as it appeared to have done nother with other users.
Still trying to find out if this is a documented bug or just something specific to certain OS/apps.

I've noticed with Facebook messenger that if I get a message right as the screen goes dark and messenger was the last program on the screen, the LED will not light up. The phone must think I already checked it in that case. Other then that, it works as it should.

Mine works aswell

Mine never fails to notify me of events, but sometimes it lights dimly with no reason.
I'am still wondering why ...

The LED's glow bright if the ambient lighting is powerful, like in Sunlight or in a well lit room, and it'll be on the darker (dimmer) side when the ambient lighting is dark, like in a dark or low lit room.

After about 3 weeks with the Note 2 I am still puzzled by the LED. I have days when it works perfectly (like you guys are reporting) but others when it just stops triggering and so far I found no pattern. Some code related to it must be really flaky. But when it works, it usually works fine...

Getting some features you've been missing back

So probably like most users I had the Note7 coming to this phone I have noticed a few things missing that I really need. One of those was notifications the lack of an LED indicator has kinda bothered me. So I went looking for the Samsung always on screen with the clock... I figured without the LED light it would have that so I found in the app store Always on AMOLED. This app help fix my issue of never knowing if I had missed a e mail or text or phone call.
2nd was the lack of the phone vibrating hard enough to feel in my pocket.. I went looking in the settings for the vibrate pattern normally found in 6.0 couldn't find it so i searched around and found an app Light flow I have used this app before to change the color of my LED notification so I can tell if it was an e mail text or phone call I installed the app to help with the first mentioned issue also when I realized it didn;t have an LED notification it surprised me .
I am still trying to figure out other features I am missing has anyone else found things that they are missing with this phone. The calander is another lacking issue for me I like the month view with cut of writing on the days I had something if anyone knows a alternative would greatly be appreciated.
I miss the wireless charging feature I knew it didn;t have it when I ordered it but I still miss it.

The pixel has a LED notification light that can be turned on in the settings by going to notifications, clicking the gear at top right and switching pulse notification light on.

We had multiple notes in the house and got free wireless chargers with them, and they all are in a box. It's slow, it's awkward, and it's just not as good as a regular old plug it in charge....

Samsung fast wireless charging is awesome and every phone should have it. Just like every phone should be water resistant.
I love the way this phone moves. Which is something even the note 7 didn't have consistently. It's the first phone I can say has made my use more fluid and purposeful.

Delayed Notifications In Android P

First off, I disabled adaptive battery in Android P. Ever since the upgrade from 8 to 9, I noticed that notifications are right around 5 minutes late. I have a couple time-sensitive apps that I need notifications right away. Gmail and another app for my home automation. In Android 8, the were flawless. However, ever since going to 9, not so much.
I also noticed that when I delete messages in the gmail app for gmail and an IMAP email server I have it does nothing with the messages on the server. I login to webmail from a computer and the messages are still in the Inbox.
Anyone have any ideas? I am going to try a wipe again to see if it resolves the issues, but I am out of ideas. I had the above issues in Android 9 beta as well. I would downgrade and it fixed them.

I have the same thing and it turns out it is a common issue with Pie. I have not found a solution yet. I have read all kinds of things people have tried and nothing seems to help. Sorry that I can't be more positive. Hopefully Google will figure something out and fix in an update.
Here is a two page post I started about the issue but there are also many others online describing the same thing:
https://forums.androidcentral.com/android-pie/904647-notifications-delayed-stopped.html

My thought is that the delayed notifications are due to Android Pies implementation of adaptive battery. Maybe try excluding the apps you want to receive notifications from in a timely manner?

You don't happen to have data saver in the quick tiles turned on by accident do you? That does prevent notifications from getting pushed. Both my parents had this on and a bunch of notifications came through after turning it off. I made sure to remove it from even being an available option.

been fighting with this issue as well, but it only seems to be gmail, and a couple other apps, my sms notifications seem to come through fine, at least as far as I can tell. I've turned off adaptive battery etc, nothing seems to make a difference. sometimes i can turn my screen on and all the notifications will come flooding in, other times they come through 10ish min later.

yes i have also these issue
and i opened thread on these https://forum.xda-developers.com/pixel-2-xl/help/gmail-sync-problems-pie-t3839357
also i tried many apps, but instead of gmail but yet i didn't find any solution

Made sure it was off early on. No change.
The best way to describe my issue is that once the screen times out and has been off for at least about 5 minutes, notification sounds are delayed. It is sort of like the phone goes into a deeper sleep or something and then the problem arises. As soon as I use my fingerprint to wake the phone, all notifications blast through.
The delay can vary. Sometimes it is only 15 minutes or so, but often it is much longer. It is almost like once in a while an app wants to call home or something and to do so wakes up the phone just enough to allow some notifications through.
There also seem to be some issues with individual apps and notifications that may be fixed when a developer updates their app for Pie. For example, most apps notify immediately when the screen is on or within that first 5 minutes or so after the screen goes off. But since installing Pie, Kuna always has a delay of 5 to 10 minutes before notifying. Kuna does this 100% of the time. In fact if I have the phone awake, looking at the screen when walking out the front door, when the motion sensor is triggered, immediately there is a notification icon. But the sound notification is always delayed. This seems like an issue with Kuna and they are well know for being very slow with updates and fixes but eventually they do fix things. But the notification sound delays described in this thread do indeed seem like a system issue with Pie. Hopefully enough people will have the issue that Google will figure it out and fix.

I am having same issues after updating to Android P. At first, notifications came late about 5 min, but then they started to vary some coming in 15-30 minutes later. Can't figure out what is causing the time difference but either way I can't find a fix. I spoke with Google support and they had no fix as well.

Nope, they didn't mention anything about existing issues or being aware of the issue.

Any one found any solutions or fixes? I feel like my notifications are becoming even more delayed now and have also realized I'm not getting a lot of various notifications at all (through many different apps).

I am guessing you all are aware of this, and have tried, however I just found this recently and thought I would share for anyone that doesn't know.... Settings > Apps and Notifications > Advanced > Special App Access ..... Lots of options here with one of them being battery optimization for individual apps. After I upgraded to P, hardly any of my frequently used apps were given full battery use. Haven't played with all the other options there, however just granting apps full battery seemed to help me out.

Just updated some settings, now we wait and see if these buried settings fix my delays.. here's to hoping! :good:

One of the first things I tried was giving full useage, (no battery optimization) for all apps that I want notifications from. Did not help. Many other apps are still being optimized. I thought I had previously found a way to turn off all battery optimization but because I do have many apps in that list that are being optimized, I obviously did not. Right now I can't find a global setting to turn off battery optimization even though I thought I did before?

So I noticed this morning, that the main app/notification that's super delayed (5-10min after the event should have triggered) it doesn't happen when my phone is plugged in or i have the screen on in my hand. Even after going through all the battery save features and making sure this app is exempt from them, it still happens if the screen is off, or my phone is off the charger. super annoying. wish there was a fix for this already!

Verizon sent me a replacement because of this problem. I was apprehensive, but got a very nice re-furb. Still have the same problem, but I got a phone that is indicated as Verizon on the LG site. In developer mode, the bootloader unlock button works. I guess everything isn't bad. I sure hope Google straightens this out soon.

This happens only with Gmail on my phone - WhatsApp and Messages send instant notifications. Messages isn't optimized, the other apps are.
I can live with that, no big deal. Perhaps disabling battery optimization for Gmail would fix this, though.

Interesting note: I was talking to YouMail support today about something else but I asked about an issue where I get an email and transcript of a new voicemail but when I go to the YouMail app that voicemail is not shown until I drag down from the top of the screen to refresh the list. Support told me they are aware of this but can not do anything because it is a problem with the "latest Android version causing delay". So it is becoming a more widely known issue and hopefully Google will fix soon.

Thanks for all the feedback. Speaking of delay, I think I have tried just about every fix here and then some and still no luck. Wiping the phone did nothing as well. At this point, I would almost like to revert back to v8 to get this fixed.

I tried this supposed fix, (reply #51). https://forums.androidcentral.com/a...ifications-delayed-stopped-3.html#post6355714
No idea if it worked for me as when you restart the phone you need to do it again and less than 30 minutes after I went through the steps, my Pixel2 got the October update for Pie and required a restart!

Places to enable notifications (L29)

I have the L29 version and right out of the box notifications seems to work great on almost all 3rd party apps. That's is certainly not normal for Chinese phones and is very much welcomed.
I do have one app however that I can never get to push notifications "HQ Trivia"
I made sure all notifications were turned on, and I also went into the battery settings and set it to manual and turned everything on in there.
Is there some other place or permissions I need to set to get notifications to work again? (Also tried clearing data, uninstalling app)
This seems to be the only app I have issues with for notifications, just trying to learn the UI so i know where everything is hidden as on my Xiaomi phones there were about 3 different areas you needed to adjust setting in for notifications to work.
