LED Notification Light Deciphering

Been doing some searching, but there doesn't seem to be much info regarding the different colors and frequency of flashes that the LED notification light is capable of, depending on the notification received on the Nexus 4, so here goes.
This is just regarding the stock setup without LED modification apps, etc. So far, I have found that the LED has a few different patterns and colors depending on the type of notification that you receive. I am also wondering if there is any way to adjust the behavior of LED notification light in the stock configuration without additional apps or rooting with custom ROMs, etc. I have checked around within the settings of the different apps but aside from a few giving the option simply to use the notification light or not, it seems that it is not possible to adjust the behavior. Here are the details that I have discovered so far:
- Gmail, stock email app, stock text messaging app, others? - White LED, flashes once every 10 seconds
- Google Voice messages, Ebay app, Official Twitter app - Green LED, flashes once every 2 seconds
- Yahoo Mail - Violet LED, flashes once every 2 seconds
- Facebook, Tasks app, Plume - Blue LED
- Flight Track app - Yellow/Orange LED
- Google Messenger, Calendar, others? - No LED notification flash
This is just what I have observed so far after about a week with this awesome phone. Feel free to add to this list based on your observations and I will update the list. Thanks!

There won't be any way to adjust these without additional apps. It's left up to each particular app to support it and pick a color.
I seem to remember the old TweetDeck app was yellow.

All apps can do different colors, but it just depends on the code. The Google+ used to use Red LED notifications, but they've since returned to using green (I think this is a step-backward, but whatever). Yahoo Mail did Purple when I last used it, and Flight Track uses Orange/Yellow. I suggest just downloading LightFlow or Rooting/Flashing a custom ROM for increased control (you can even specify blink frequency and other settings). The problem is, not many phones have had RGB LEDs, so App Devs have no reason to support them. With the GS3, New RAZRs, and the Optimus G/Nexus 4, hopefully this changes, although the LEDs seem to behave weird on some phone models, especially the RAZRs...

could the red LED be for sync error? google mail had an outage the other day.

Facebook notifications are blue on mine, which is neat.

Good to know, although I don't use Facebook right now.

My LED didn't work from the factory, installed light flow and now at least it works the way I would have wanted it to from the factory.

I wished Google + would use the red LED again. I thought it was cool with the FB blue and G+ red.

Plume (Twitter app) also is Blue by default but can be customized in the settings.

Just got an eBay notification and they use green too. I would have assumed yellow....
Edit:
Forgot to add, the flash rate is fast, like on one second, off one, then back on.

Get Lightflow:

It'll take about an eon or so to set up, but once it's up and running it'll change your life. I have customized the LED notifications for all of my different accounts/apps in such a way that I rarely even turn my phone off vibrate anymore - I can tell exactly what is waiting by looking at what color(s) are displayed on the LED.

Good info and thanks for the comments! Also I am aware of light flow but am just looking at the stock setup.

Before I go with lightflow, I'm going to need to see two things. 1. Full compatibility with the N4 (there are bugs) and 2. Proof this won't drain my battery or prevent notifications from appearing. My battery isn't doing too hot and I don't need something else draining it!

One of my LEDs is dead
What color LEDs are there in there? I'm assuming RGB
I noticed my colors are off, tried several LED control apps, particularly "LED Tester", and none can get the Blue LED going. And my white is yellow. G and R are fine. Any advice beyond LED is dead?
I'm so sick and tired of QC on this phone ... I think I'm done with it. Returning for a refund, money wasted on now useless accessories, some of which are still in the mail

I prefer Light Manager. Much easier to set up. Plus notifications for charging.

Lightflow has notifications for charging. I say it's a pain to set up initially because picking a color for 41290 different notifications can take awhile, but the setup really is quite intuitive. It's been changed a lot in the last couple months - might be worth looking again some time.

I've had no issues on my Nexus 4 with it. It's never drained my battery on this nor my Galaxy Nexus. Its memory footprint is tiny and it has no reason to wakelock the phone since all it does is intercept when a notification shows up (so the other app is what actually wakes the phone). It's really well designed.

One question for you. I know that because of how light flow works, if it doesn't support an app the led won't work on that app even if that app has it's own led ability, but will the phone still display the notification (minus the light) for an unsupported app?

If you guys are rooted and installed the stock AOSP browser, for some reason Light Flow breaks it.
Once light flow is installed and permission is set in accessibility, the stock AOSP browser starts behaving badly and stops working correctly.
The autohide url bar stops working, when changed to full screen mode there is either a glitchy image at the top or a blank black area where the url bar is supposed to be. Problem completely goes away once light flow is uninstalled.
Very frustrating because I can't stand Chrome, and I need the AOSP browser + lightflow. It's either one or the other.

Have you talked about this issue in the Light Flow thread here?:

Maybe it helps to get it solved.

As far as showing up in the notification bar? Absolutely. The apps themselves control that, not lightflow.
Personally I don't have any apps that lightflow doesn't support by now, but I'm sure there's some out there.

XXperia Z notification Led colors?

I know RGB is there..But i have seen pink/purple, Orange
May i know is it multi-color and what apps can be used to change each?

i've only seen orange/red and green....how did you see the others?

Try an alternative LED application like Light Flow or Led Blinker. Cheers!

You can have like any color that you want, the only thing is that you can barely change the color of the led per ap. You can with 3rd party aps though.
When you go into WhatsApp settings you can change the LED color for that ap.

Thats great..means its multi-color...May i know what the basic colors signify?
Green = Fully charged...and rest?

Orange = charging
Red = low battery
Purple = cwm / whatsapp
I think its green / purple for SMS.

You can see/test LED colours under Whatsapp's settings! There are 7 different colours :angel:

Yup there are 7 different colors on WhatsApp, but there is only 1 LED, so you should be able to make what ever color you want.

Most likely to be carrier specific mods

I have an unlocked XZ

I have NO leds at all, only while charging and such, but none for texts or such (sms), bug ?

Hi guys,
Found out my phone can't show the led while in Stamina mode. I read somewhere that you can still have the led going even with Stamina mode if you use a third party app to manage the led and set that app in the stamina mode's white list. Tried Light Flow but it didn't work.
Anyone got lucky with an app?

Rango advised Light Flow or LED Blinkers apps. I don't know about Blinkers as i have not used them, but Light Flow is superb, maybe a bit too complicated, to much settings, but it's great, only thing is that you need to have the paid version, as Lite does not support custom apps.

LED Color Change

Is there any way to change the color of the notification LED on the Note 8 without root? I'd like to change it for each specific notification (gmail, missed call, text, etc.). I have tried Light Flow with no success.

I use light manager, have been using it for years.
On the note 8 it works well for notifications, and works for charging but not as well as previous phones.

What is funny is there is a "LED Icon Editor" in the Notification Access area in settings. When I click to allow it to access notifications it goes right back off. I can't find this app anywhere else on the phone.

This is actually for the LED Case which you can customise the LED notifications

For anyone finding this thread later, LightFlow works with the Note 8 without root

The problem with Light Flow on the Note 8, though, is that it appears that, even though I believe the LED is capable of RGB, it gets some colors very wrong. It may just be custom colors that are the problem.
Light Flow also now does a bunch of other stuff, aside from the LED. You can have it filter notifications based on pattern matching, make a different sound, repeat the sound, use a popup, add vibration. It does a bunch of Notification-handling stuff and is a bit simpler and more reliable (in my experience anyway) than trying to use a cobble of Tasker + AutoNotification.

I also use light flow and I've had no issues once set up although I do have the colour differences, e.g. select white and the led flashes a purple'ish colour.
Other than that it's been fine, negligible battery usage too.

That setting is for the LED wallet cover/case Samsung makes for the Note 8 and can only be turned on after inserting the phone is to that specific case.

I use light manqger, since S3, then, the colors were accurate, but in my note 4 note 7 and now with the note 8, I find the colors missrpresented, no white, but a bluish tone, no yellow, but a somewhat orange tint, etc, so, I guess the led is not capable to display accurate colors, but, for me, that is not a big deal, the available color suffice my needs

Sorry to bump a 2 year old thread but does Light Flow work for Facebook Messenger for you? I can't seem to get it to display blue color for Messenger no matter which app I use for changing LED colors.

No worries, although I don't think I can help.
I no longer use Messenger however I did used to be able to assign a colour of my choice to it, but who knows how the app has changed in the last couple of years. Not only that but I have a Note 10 now which has no led light :/ Sorry bud

Thanks for replying. I found apps that work but all of them make another notification which is seen on AOD and it just bothers me. Ended up with default LED light and custom Edge Lighting colors for each app with the Edge Lighting Fix App

LED notifications

Hi guys, I'm just about to buy the P20 Pro, but I have a question.
RGB LED's notification are fundamental for me, I don't want the AOD, but I want to know what kind of notification I have on the phone just by looking at it, like I do now on my G4 (red for gmail, green for whatsapp, blue for messenger, etc.).
I've been playing with the P20 Pro in a couple of occasions, but I couldn't find anything in the setting about changing the led color.
Also, anybody tried using the app Light Manager? It's the one I have on the G4, works perfectly, I sent a email to the developer and he told me that right now it is NOT fully compatible, but I didn't have a chance to actually try.
Thanks a lot!
Will

Mine only seems to show white or green..

Tried the app and seems like every color predefined works perfectly. I use Light Flow to get more options.

Great news then, so now I’m wondering if the P20 Pro is able to use the full Rgb capabilities or if we need something like light flow to unleash them...
Btw, even if if it shows the base colours of LM, it’s good enough for me.
Thanks a lot for your answer.

Notification Pulse Color

I looked to see if I could find this answer on here and on Google please flame away if it's a repost. In the chroma app I set the led color to red. I tell it to pulse if I get a notification,but the pulse color is not the color I selected it is a light blue is this normal?
Thanks

The colour you set in Chroma is just for the passive effect. When you get a notification it tries to find the most prominent colour in the app's logo which sent the notification and uses that. It's meant to make it more useful than a plain old notification LED since you can intuitively determine which app sent the notification just by looking at it.
So yeah, that's normal

Gotcha I will pay closer attention to it seems a little odd to use light blue for Hangouts which is green. Maybe it's just not that accurate
