Purple light?

Help please. I'm trying to sleep and there's a darn purple light blinking. I have no notifications or anything. What could be causing this? It used to happen on my Optimus G Pro but I just blamed the phone. What could it be?
Thanks!

Do you use lightflow? Sometimes the "notifications" or whatever don't clear properly from lightflow even if notifications are cleared light flow keeps sending LED signal i guess. The way to undo this (until it happens again) is to go into lightflow, go to 'Tests'>'All Enables LEDs Test' then click 'STOP' to stop the test. This will stop the test thus removing all LED notifications or whatever. Happens to me all the time.

Was your battery below 15%? I had the same thing around 11 last night and "cleared" all notifications in light flow and it kept coming back. I think the default low battery was purple.

I had the random purple light blinking too. Maybe lightflow needs to be updated for 4.4.

works fine here...though i have an n4 with 4.4..maybe nexus is an issue...but like i said sometimes clearing all notifications DOES NOT WORK, this has ALWAYS been a random issue with lightflow some notification refuse to get cleared from lightflows queue. What you have to do is manually clear lightflows notification queue ..just follow my post above.

Seems to be a hanging application since you also had the same behavior on your G2.

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.

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.

LED customised light not working...only "default" blue light

Hi
Does anyone know how to set up custom colour led notifications on s7? All I get is blue light. Tried light flow and light manager. It looks like Samsung made it difficult for some reason to set your own customised led notifications. Tried the recommended (by these led apps) "Samsung walkarounds" but still nothing. I tried
disabling notifications in Gmail, system's led notifications on ...nothing. Is there a fix for this?

Probably not. I corresponded with the LightFlow dev last year for a while regarding the issues with the S6. Basically Samsung has implemented their own code controlling the LED and it does not play nicely with LightFlow. He tried to implement some workarounds and there were some custom settings in LightFlow to try to get it to work but ultimately it was super buggy and never worked correctly. I ended up uninstalling LightFlow and just dealing with the stupid and unintuitive stock colors. :/

Thanks for reply. I wouldn't have a problem with keeping the stock led but it's pretty close to being useless. Blue light only for all notifications and even that is not reliable...and don't even start with red and green lights...I'm going to stop reading "professional" reviews because nothe even single one mentioned that led notifications on Samsung phones are screwed. Why Samsung decided to mess up this great and highly usefull and practicall feature is beyond me. This is exactly why people stick to Apple. Am ranting a bit, sorry.
Wonder if rooting & flashing custom rom helps with this.

I contacted the Dev in the weekend and this is a temp. fix.
In Lightflow, enable "Switch screen on" on all notifications that's not working, ex. phone, email, twitter, etc. Restart your phone and it should work. It works for me.
I swear by Lightflow. My favourite app.

So you have to have the screen come on every time you get a notification and then lightflow works as normal?
This is bringing back bad memories of hours messing around with this on my S6 lol.

Thanks but having screen switched on and off every time I get a new email isn't really an option for me. It would kill my battery in a few hours.

S7 - SM-G930F - 6.0.1 - unrooted

Light Manager is working fairly well for me. Different colors and 3 second interval.

Hmm, it actually seems to be working for me too, although I did get a message to install LightFlow Legacy app for some reason I can't remember now? And it said to disable the full version which is odd. All these strange workarounds thanks to sammy.

Eh it's partially working now. Blah.

So it seems to be working fairly well, except for Hangouts. It simply won't blink green as I have it set to. It seems to still use the default blue color and slow blink. Anyone else have this issue?

I use led blinker pro... No issues... Have full control over led colors, length of notifications, blink rate etc...

This should help:

I already had that setup with the exception of the "device default" for the screen on time. Still doesn't work for me but I guess it's due to the fact that I have the always on display option turned on. This is reinforced by the fact that I get the blue LED until I turn the display on, and then the color I'd set after that.

Yep, that's the sign of the AOD issue. I decided LF gave me more useful information than AOD, so I turned AOD off. The LF developer is getting an S7, so hopefully he'll be able to figure fixes for these issues.

Light manager has been working almost perfectly for me with my exynos S7. The problem I am having now is that I can't find a way to stop gmail from causing the slow blue blinking LED and this always supersedes the light manager LED so if I get an SMS notification and then get an email the blinking blue light will cause the SMS notification to stop. So annoying. If I can figure out a way to stop this from happening I will post it.

i installed light manager today to...and different led colors seems to work

I actually just ended up freezing gmail in titanium and installing blue mail.

LED, where is it?

can't find the LED notification light. it won't come on while charging or anything... is there a setting for this? the only setting i find is for pulsing, but that won't do much good if the thing doesn't even come on. is there a setting i'm missing?

I think the default setting is on. The blue color (which I think is default) is harder to see than other colors, at least for me. I was able to see it better when changing it to red or green for a given app.
That being said, the fourth small bug which I've noticed is (at least for the few apps I've tried) if you disable sound for a given notification, neither ambient display nor the LED will work for that given notification. I'm unsure if that is intended behavior or not.

How do you change the colours for certain apps. I hoped the led would have been brighter and covered by the glass so it never needs cleaning.
Thanks.

It either has to be baked into the app or you'll have to use a third party app (which may or may not require root).

my pulse notification setting is on. i have an email, a text, and i'm charging and there is no LED anywhere to be found. is there another way to test it? maybe my unit is defective.

Are you looking VERY carefully at the left corner of the earpiece speaker grille (where the LED is located)? I thought mine was defective too until I saw how faint and small it was.

i have a text, on the charger, and i'm staring where you say but nothing. on chat support with google right now. i think mine may be defective but i'll know more in a few...

The LED is nothing special. It will flash for me every once and awhile if I have an Allo message, and if I don't read the message, it will flash as soon as I lock the phone - I did this several times just to get a good look at it. The LED is directly behind the cloth speaker cover in the earpiece. It looks like ****. You can easily identify each red, green, and blue LED when they are trying to display a white color. It doesn't even look white at a distance - you can easily see red, green, and blue. And if the phone is laying flat on a table, you can BARELY even see it. Surely it will not grab your attention unless the room is pitch black. Don't know if they thought it would be cool to do this, but it looks terrible imo.

i didn't finish the tech support chat cus i had to get back to work, but eventually the LED did show for an instant after i got an email.
it showed for an instant, and gone. i waited for it to show again and w/in 20 or 30 secs it did not show. this is what i call a useless feature. makes no sense. why is it even there?
there are so many things about this phone i don't get, and these are not bugs. i guess this is what happens when you smooth everything out for the mainstream or Apple crowd. i'm returning the phone. nice phone, but not for me at this price.

Lightflow does a good job enhancing the LED. Even without root, I now have a charging indicator and fully charged green LED. You can customize other apps too.
With the exception of having used the app for a long time, I do not know the dev, nor have any interest in his/her ventures.
I am linking the paid version as I am a strong beliver in supporting devs that turn out useful apps. There is a free version also.

Enjoy..
Edit: There is another app, called Light Manager, that I have previously tested. In the end, I found that Lightflow is the most flexible and useful for me.

Lightflow has more features. It takes more work/tweaking, but I can do more with it. For example, I use Lightflow to also control ringtones for some apps, as well as reminder tones. You can also control vibrate/volume characteristics. Light Manager does not offer that.

I am running LF on my PXL with no wakelock issues. Battery life is great.

I wish they would put the LED from the Galaxy nexus on the new phones. It had an awesome LED. Theres plenty of space for it on the button.

Been using LF for years. Great developer.

I use light manager pro myself. Just got the pixel yesterday

Notification LED Does Not Blink

Although I have the setting enabled, I miss messages for hours because I never see the LED blinking. I know the hardware works because it lights up during charging and Textra can enable the LED through it's app. Do any of you have notification LED working for non-messaging apps like email, xda, banking, etc?

After searching around the forums and the web, it appears that EMUI only shows LED notifications for stock apps. It will only blink for 3rd party apps if those apps have an option within the app's setting. I am missing so many notifications because of this. Without that blinking light, the phone looks like nothing has happened, causing me not to wake it up to view the missed notifications. I hate this so much! This is the same problem I have with iPhones. You never know when a message is waiting for you because it doesn't blink. The phone could be completely powered off and you wouldn't notice until you tried to wake it up.

Thanks for the suggestion. Light manager works great, but it prevents the phone from sleeping and caused horrendous battery drain. I'll just have to get used to waking my screen regularly to check for notifications. Not only does this look like an iPhone, it acts like one too! Lol

LOL like the quote.. "Even acts like one" (iphone)
I must say I use Lm Pro 11.2 and I don't get the battery drain now. I used to but after a few clicks of the Phone manager my device has settled down OS is B360 L09.

Since I have read this I saw that notification led is working. At least for viber and it is like viber an purpel led color.. I did not saw for regular messages at least for now.. couse all was over viber.. but yeah its working..
Will report if the regular message will trigger the led notification

Yeah, I know messaging apps will trigger the LED, but a lot of my other apps don't get the same treatment. My banking app, my home security app, and even Google now traffic alerts don't trigger the LED. It kinda sucks!

For now it worked for normal messages with green led and viber with purple led..
Will try to see what about other apps like notificstions from you tube maybe..
If it is like you said for banking app and thoese other apps it may be incompatibility with this sistem or just with the setting option..
Becouse if it would not work at all then it would be something different.. but since some of default apps works and some not.. it could be the app incompatibility..

I think it'd a flaw in EMUI, because this didn't happen with any other Android phone I've ever owned.

You are right

Honor 8 LED light not working all of a sudden
I have a problem with the LED light stopped working at all. Yesterday, there was a red light going on for hours, which made me turned the phone off. Today, the LED light just stopped working for any apps and doesn't even lights on while charging. I have switched into the option of setting the screen on whenever I get a notification, but it's not the same as the LED light, because this drains the battery. Does anyone have an idea on how to fix this problem? I'll appreciate it.

Did you try a wipe cache or an Hard Reset?
