[Q] Light Flow/notification LED issue - keeps flashing

Hello everyone!
I recently replaced my 3 year old Nexus S with a Nexus 5. It's my second smartphone and I love it. Naturally, I rooted it and everything.
One of the apps that peeked my interest was Light Flow. It's a bit mind-boggling what you can do with it, but I'll figure it all out. However, I noticed one issue straight away...
Notifications in different colours seem to work. I did a test with whatsapp and it blinks green: perfect. However, after a couple of "blinks" a white light flashes "through" it if that makes sense. It doesn't alternate between green and white, no, they just flash through each other, the white light slightly before the green light.
I don't know what is causing this white light to flash, but after I turn off Light Flow and close the app entirely, it keeps flashing. I have to restart my phone to make it stop (or disable notification LED in the Android settings menu).
Does anyone have a similar issue? Or can someone maybe tell me what boxes I have to tick in the Light Flow settings? It could very well be one of the settings is causing this issue. If someone has a certain set-up and it works fine, I'd love to try it and see if it fixes my issue.
Thanks in advance!

I installed LightFlow yesterday for the first time.Worked well, but after receiving a notifcation for Whatsapp and Gmail (and opening up the respective apps, the notification carries on until I reboot.I dont know if there is a setting somewhere (doesnt seem likely?) or if it is a problem with kitkat, uninstalled for now

Do your notifications work by default? Like, your stock notifications? Mine didn't, but do with light flow. Weird, no?

Yes, notification light works as it should

I tried another app (Light Manager), and I had the exact same problem. Don't get me wrong, the app is working fine, but once I set everything up and I do a test notification, a white notification keeps flashing even after I turn Light Manager off. The only thing that helps is to disable LED notifications in the Android settings, or to reboot the device.
Something is telling my device that there's a notification, but I don't know how to fix it.

Make sure in your phone settings, security that lightflow is switched on.

The test option isn't great at the moment. Follow the steps above and it should work

Thanks for the personal reply, andrew! I really appreciate that
However, for some reason my phone keeps flashing this white light, even after I turn off Light Flow. I have to turn off the notification LED in general or reboot my phone for it to stop. The white light notification starts after I do a "missed call test" like described in that link (that works perfectly fine by the way), or after any test I do with Light Flow for that matter. And it doesn't stop no matter how often I clear my notifications.
EDIT: NEVERMIND. Totally forgot that I don't have a sim card yet. That's what was setting off my notifications. Weird though that even after disabling Light Flow it keeps flashing, and weird that it was white instead of cyan like it's supposed to be.

Sorry for wasting your time. I totally forgot I didn't have a sim card so Light Flow was making the LED flash because it thought I had no signal.
Still weird that it keeps flashing even after I disable Light Flow, and that it's white instead of cyan like it's supposed to be.
Anyway, thanks a lot for your help! It works fine right now. I'm not too sure how the cycle thing works yet. I've tried it with a red slow flash for low battery and a green fast flash for whatsapp but the result is the LEDs flashing kinda "through" each other. Naturally, with different flash rates, I guess.

Quick question for people. For the last couple of updates I've been getting quite a lot of reports of certain notification types not working. Hangouts, emails (not gmail), whatsapp etc
I know that all the types that people are having issues with have been using the notification listener (quite a few stock apps don't use it), has anyone else been seeing this. I'm trying to track it down, but I can't recreate it and the beta testers haven't been able to either. Just interested to work out how much of an issue it is as I've never had reports of this before.

Hey Andrew,
I tested the color cycle for textra app, and google voice. I purposely got both notifications with the screen off and waited for the colors to cycle. It started off cycling both colors, but the cycle was not consistent. For example, the colors were red and blue. It would show like this- blue....red....blue..red..blue..red....red....red....red....red
The time between colors was not consistent, then eventually one color took over. I have the setting to 'cycle all - medium' under battery settings. Have not tested under charge settings yet. I am not using the 'highest priority' or 'show latest' options.
This isn't a deal breaker, but would like to bring to your attention.
Thanks!

I use it for WhatsApp, BBM, Hangouts all w/o issue on my stock N5. My only complaint is the perma-notification in the notification tray. Can't seem to get rid of it with any of the options in settings. Wasn't an issue with older versions (I'm using the latest)

Ive been using lightflow on my N5 and it's working well
I have multiple notifications set up - all set for 'permanent' rather than flashing. I have turned EMAIL notifications OFF
however - sometimes, I am not entirely sure when, I notice a white (slightly bluish?) blinking LED. I can't figure out what causes this. I suspect it MAY be email (exchange email, not gmail) - but I am not sure - I can't reproduce consistently.
Also, sometimes when I do a 'test model' on SMS apps, no LED lights up. I've stopped using "SMS Apps" and now am using "Hangouts" as a notification instead and that seems to work

Had 2 hours full wakelock on lightflow this morning -from the minute I unplugged from charge
very strange

Isn't the white light you're seeing the default LED color? Whenever I get a Gmail or Exchange mail it blinks white. I don't have Light Flow installed.

Yes I think it is the standard light. however with lightflow that's not meant to occur.
either way it appears to have stopped now.. not sure how/why!

Try turning off your LED notifications in each program and just have Light Flow control them. That should stop the default white light from showing.

I had a same problem. I dismissed missed call, but LED light was still blinking. And second time this happened for gmail.

Hey Andrew, Great work on this app. It is fantastic and I was happy to upgrade to the full version.
Just wanted to share that I have the lingering notification scenario also. essentially I get a few notifications and once I clear them out and the screen turns off, the light continues to blink. It is usually the last notification that came in (I have different colours set and I can tell that what sticks is what came in last).
To be honest, I wonder if it is Kit Kat not clearing out the notification and the issue has nothing to do with LF. Interestingly another way to clear the issue is to bump the notification with another real one, and then accept that notification (i.e. light still blinks without any active notification, I call the phone and miss the call, it blinks for the missed call, I clear that, and we are back to normal)
Hope this might have helped.

Anyone able to get the Camera Light LED/flash to work? The one on the back.
I enabled it in setting and I've tried all the other ones not officially supported too with no success.
Also had the notification light not dismissing problems too. But I'm thinking I got it figured out now. Hasn't happened since.

Light Flow

Has anyone been able to get Light Flow to work on the OnePlus One? I like light flow a lot better than the CM notification center, but I just can't seem to get it to work.
Has anyone here getten it to work? If so, mind sharing your settings?

So far I've had one person say it worked and two not!
Can you try and see if led color tester by coolbeans works on the phone (with lightflow either not installed or disabled) and let me know if that works?

I'm interested in this as well. I enjoy Lightflow so much more than any of the other notification apps I've tried. I'll be heartbroken if it doesn't work...

i used lightflow with paranoid android and it works fine on my oneplus one chinese version

Hello. I'm a big fan of your work (been using on the N4 and N5).
I also have this app on my OnePlus One. I noticed that up until the most recent build that all my notifications were working. Gmail and stuff were all fine.
Is it me or did the latest build change something? When notifications come in I get a white light blinking. When I power my screen on and off again it seems like Light Flow then registers, and now I get green pulses.
I'm not sure if its the most recent build of Light Flow or if its because I added a second Gmail account). I am rooted so I'm on root mode, but maybe some of my settings are whacked?

Yep, have the same "issue". Before the last Update everything was fine..

No Light Flow issues here.
Just got my OnePlus One today. Installed, restored the app generated backup from my S4, good to go.
Some apps need to have their own LED setting disabled for LF to work properly since the last version.

I'm aware of this for some users and I've just pushed out an update (it should show in the play store over the next few hours) I've had a few people testing who had that issue and reports so far seem to be that it fixes that issue.

You sir are a hero. It no longer requires me to use Gravity Box UNC to override settings.
Question: Do you recommend for high end phones like the N5 and OPO to run in foreground or background? I see no issues with background on my OPO and the app doesn't get killed at all.
Second question: You're still going to roll out global settings someday right? Having to change speeds for every app is a bit annoying, or even custom blink settings.
Final question: Is it possible to adjust the brightness for the LED? I see a brightness option in the sleep options for night blinking, but adjustments for individual notifications? Would be nice to have global for this too

On the N5 I find it does work better with the option on, without it once every few days maybe it'll get killed off by android (which is fairly normal for any background service) so it'll miss a notification.

Yes that's still on the list. If google hadn't brought out android L I'd have been working on that, but I've had to divert my time to issues with that!

There's a global option for this (in lightflow, settings, general settings, led brightness), but not individual, you'd just have to use the custom color option at the moment.

Lightflow works for me.

I can't get LF working, or if it does work it just flashes white. I'm 100% stock/unrooted so is there anything else I need to activate to get it working? I had no issues with my previous Nexus 4/5 so it must be something silly!
EDIT: Reinstalled and seems to be working OK now, so obviously something I did wrong!

Thanks for the help @andrewpmoore
Is it possible to have the lights on even when the screen on? Is that the "Samsung direct mode?" I don't believe that worked on my other non Samsung devices, so I doubt it will work on the OPO.
I ask because CM's battery LED seems to by default remain on even when the screen is on or off.

Same here. Rooted. Locked bootloader. Dunno if it matters...
Correction! There seems to be a small glitch: At the end of Charging when switching to Charged it seems to start switching between Charging and Charged rather than just using the Charged notification.

I've a fix coming for switching between charged and charging.

What 'Device Settings' is everyone running to make this work? Is anyone using:
Direct Mode?
Samsung root mode?
Reset color before change?
Nexus 5 force LED reset?
For some reason mine works for a period of time than I start getting SMS's and it stops working. I restart the app, but it doesn't continue to work again. Not sure what's going on.

The glitch seems to have exploded... nothing seems to be working now... not mail, not sms ... nothing. Tried to enable the root option but it makes no difference

The Nexus 5 thing is the only box I have checked (must've been by default since I didn't do it).

Not having any issues... maybe backup your notification settings and then wipe and restore them. Ensure LF has the proper notifications access, etc.

Nope. Nothing. Tried to clear the cache and data. Tested the notifications and nothing... Checked Notification access and tried enabling root mode. Still nothing... Phone is stock though rooted.

Is there any way to flash / blink the camera LED on call / ring / sms ?

Hey everyone,
I want to flash the camera LED (Not the notification LED) on incoming call , message , and SMS / MMS .
I have tried just about all the free apps on the market attempting to do so, with no / little luck. Some just don't work at all, and a few will flash on TEST mode but not actually work when ringing. [Edit: Some work great on SMS / text but NOT ringer ... wtf ???]
I found one or two that will flash AFTER the ringer stops, but not consistently and nothing works like it should. Also nothing will actually flash while the phone is ringing. I tried Flashlight Notifier but you have to pay for PRO to use the ringer option, which I am afraid to do since nothing else worked....
I am using ViperOne 3.2.1 on HTC One M8 -- I have also tried the VenomTweaks settings of notification flash and added people and phone but that doesn't work either.
A few apps that I tried have Accessibility on/off service, which I have enabled and still no luck.
Any suggestions ?
Thanks !

You want it to flash as often as the notification led or just once when the initial notification comes in?

Well, just flashing on the original incoming call would be great.
In a perfect world mirroring the notification LED, at incoming call, on voicemail, sms and text all would be nice but all I really want is to flash while the phone is ringing....

Awesome, that would be cool...
I know zero about Android code, but in my head it's just something like:
----------------------------------------------------------------------------------
On Rintone_Activate call Flashing_Timer
On Ringtine_DeActivate (Halt Flashng_Timer | Camera_Flash_OFF )
Module Flashing_Timer (
:Loop
Camera_Flash ON | Wait 1,1
Camera_Flash OFF | Goto Loop
)

So... Quite a funny outcome here...
So unless you write an app including permission to access torch, if torch is turned on in anyway (outside of an app with permission) the screen turns off...
So what I did was wrote a nice little script to monitor when /sys/class/leds/green/blink so when it's set to 1 /sys/class/leds/flash_0/brightness is echo > 200 for 500ms (half a second) then echo 0 > /sys/class/leds/flash_0/brightness . However because of what I have found when that does happen the screen goes black for a second while torch is flashing.
Il keep working on it to see if I can get something a little more usable.
Still having an issue monitoring /green led

ok so this is what ive come up with for the time being, since i see no foreseeable way around the screen flash issue, and there for dont see a point in dedicating more time to this.
download tasker.
create a new profile.
select event
select file
select file modified
type
Code:
/sys/class/leds/green/blink
then back out and create a task.
label it what ever you'd like
press the + and select code
select Run Shell
in the command field type
Code:
echo 200 > /sys/class/leds/flash_0/brightness
the check the box next to Use Root
back out and click the play icon bottom left, this will prompt you to allow su access.
all done, now in the phone settings under sounds and notification select what app light notifications you want to use, and whenever the green light changes from on or off status the torch will flash once.

Problems with LED notification apps

Hi guys,
I hope somebody can help me.
I'm using the S6 on stock rom (Android 5.1.1.). However, none of the LED changer apps is working. Tried light flow, LED Blinker, Light Manager ...
I enabled LED lights under android settings, gave each of the apps the necessary rights, even priorities. None of it worked.
Light Flow - > Messenger app color is not changeable, all others are (but somethings they don't work either)
LED Blinker & Light Manager -> dont work at all
Thank you for any help!!!

Hey! Light Manager has been updated today. It is working for me, even though it was working in the last release too. Try to re-check your led indicator toggle on settings

I'm going to try this too I subscribed to this forum to see the problem everything works even when I test the led but every time I receive an sms, it just blinks to stock blue.

Still not working and I haven't gotten an update for the paid app today at all. It just keeps blinking stock blue at the stock rate. All the settings and all the permissions are where they are supposed to be. I have the app set up the way I want to but it's like the phone is just ignoring the app.

Thanks for the advice. However I tried light manager, but I still have the same problem as Clyff. Only some functions like recharging work.
Gmail still uses the stock color blue and ignores the app, no matter what settings/restarts etc. I did.

try to use different collors, as some collors look really different. Pink works, red works, purple works, white works.... And yeah, it is definitely working for boxer (my email client), whatsapp, facebook, charged/charging/low batt statuses, etc.

All of you with working apps are on 5.1.1? I have also not been able to get any apps working correctly since the 5.1.1 update, even with root. Seems numerous users are reporting problems with Light Manager since 5.1.1.

Yes 5.1.1.

nah, I haven't updated yet. 5.0.2 XtreStoLite deodex here.

Yeah 5.1.1 lightflow paid version.

You got LightFlow to work on 5.1.1? Mind sharing your settings - did you set anything special, like root mode or direct, etc?

It works for the most part with the screen lighting up and for basic settings but I couldn't get it to change sms mms and other aps led settings. That's the only problem I'm having. It works with low batt missed calls etc. But won't work with sms mms messenger kik etc.

Sorry to bump this up but I worked out what the problem was for all out there with issues with the LED notification app's since update to 5.1.1. On settings under sounds and nonotifications, right at the bottom there is the LED INDICATOR switch. And its default to off. Not sure if it was there before. But after switching it on and clearing cache on LED blinker pro. All my notifications work as before. Hope this helps

Glad that sorted out your problem. That is not the issue affecting most users, unfortunately. McKoo who develops Light Manager is continuing to do some research with user submitted logs. I'm still holding out hope.

What happens if you try using led blinker lite? Not sure I if I understand the issue some folks have sorry. Not being a pain. For some reason I never managers to get light manger or light flow to work on my S6 from day one on 5.0.1. And then blinker stopped working too. Which I am glad I found the remedy. I'm on stock everything not rooted.

Lightflow app developer is working on a fix.

I have started a own thread for led blinker.

Workaround für Samsung 5.1.1 Firmware Probleme ist in Arbeit!
Workaround for Samsung 5.1.1 firmware problems is in progress!

✔ Samsung 5.1.1 support added (see appsettings at the top!)
Does the LED of your Samsung device just blink blue since you updated to Android 5.1.1? Start the accessibility service (if available) AND enable the notification access (under sound and notifications or security). Furthermore you SHOULD disable the light/LED in the activated apps, do NOT disable the notification itself (e.g. in Whatsapp, Facebook, Twitter, Google Inbox). With these settings LED Blinker should work as usual.

I have the S6 (SM-G920F). Lightflow does work for my LED's, but for some, e.g FB Messenger, the colour doesn't flash the colour I've set it as (flashes green & I have it set to blue). I also have Light Manager Pro on here, same prob. (I know it's the least of everyone's probs here, as some hadn't got it to work at all, though hopefully they have now).
5.1.1 - the scurge of Android!!! I bricked this model the last time I tried to root it (& I've rooted a lot of phones) so am too scared to risk it again, even with a Custom ROM.

Notifications not appearing until the phone is unlocked.

Hi,
I have owned Find X2 Pro for about 3 weeks now. I have noticed that my notification is not appearing when the phone is locked. It only shows up when I unlocked my phone.
I know Oneplus also has this issue but can be fixed by disable battery optimization.
Is there any thing I should disable or enable in order to alert me when my phone is locked.?

Have you tried going in to Privacy<Lock Screen and then selecting show notifications

Hi mate. Did you sort this out? I have the exact same issue. As soon as screen is locked, no notifications. If I knew this I would not have bought the phone. Thanks for any help you may give.

I was disappointed to discover there is no notification LED on this phone, so wanted to find a way to overcome that. I'm not sure it's exactly the same issue you've found, but maybe the solution is the same?
There are several ways to replicate the missing notification indicator, but the one I've been using since I got the Oppo is NotifyBuddy. Although there is a free version (link below), I quickly paid a small amount of money to unlock all its features. This means that notifications appear on my lock screen in the form of app icons - you can select the size, colour and which ones you want to show from a list of all your installed apps. I've set mine to blink on and off at one second intervals and for NotifyBuddy to not show any notifications when the phone is in Do Not Disturb mode. A double-tap brings up the lock-screen fingerprint sensor, so it's easy to open the phone without even picking it up.
This is my preferred set-up, but the program is very flexible. It does consume some battery power because I've set it to run in the background (which seems pretty essential to me) but the extra drain is very small.
You can get it from the Play Store here: https://play.google.com/store/apps/details?id=com.xander.android.notifybuddy&hl=en

Thank you John for your reply,
I do not think this will solve my issue nor the original posters issue. When the phone blinks out and goes into its hibernation state/lock screen state and has been idle for quite some time, no notifications come through until the phone has been picked up or woken up then all the notifications flood in. I have tried all sorts of things to get the notifications to work when the phone is in this state but it just does not work. However, if the always on display is on, all notifications work perfectly as the phone is not in that hibernation/resting state. I am not sure this app would help until this aspect is resolved, unless in your experience it has fixed the issue?
Thank you for your reply.

I don't know if this will solve your issue, but, have you tried to turn the "sleep stand by optimization" off?

I have just tried this now. So by locking the apps in they should notify regardless yes?

When the phone was in hibernation, I wasn't getting any notifications through either. The app I suggested solved this. Now I get notifications immediately, whatever the phone's state.

Hi John,
That is good to know. I am currently trying Tobias14's suggestion, if this does not work I will most definitely try yours. Thanks again.

Also whilst I am thinking about this, supposedly lock screen magazine can impact notifications if it is turned off so I have enabled this too.
Cheers.

I thought I'd add a photo of my Oppo Find X2 Pro showing how notifications appear on my lock-screen whilst the phone is locked. This is thanks to the NotifyBuddy app which I've discussed earlier in this thread.
Sadly, I seem unable to embed the photo, so here's a link to it:
https://www.flickr.com/photos/john_gass/50301729781/in/dateposted-public/
It shows three simultaneous notifications... Twitter, WhatsApp and TypeApp (which is my preferred email app). The strange position of the icons is because I set up NotifyBuddy's ability to move the icons around to avoid any possibility of OLED screen burn-in.
And finally, I have no connection with this app except that I've been really pleased with it and feel it deserves a bit of promotion!

I am facing the same issue on my oppo reno 8, in my case sleep standby optimization is turned on, because of which I am not getting notifications on lock screen. Make sure you turn off sleep standby optimization. Settings>>Battery>>Advanced settings>>sleep standby optimization.
