[Q] Questions about LED notifications.

Okay I know everyone knows that their Droid 3 has a LED notification light, but if anyone can answer this question, help me out. Does the modification of the LED flash speed and when the light is on (meaning its on while the screen is on) require some type of custom kernel, or just a custom ROM. I've tried multiple LED notifcation apps, and none of them can change the flash rate (even though I set it to different values). I would like to get to the point of adjusting the flash rate, and make it so more important notifications light up all the time (like the 10% battery notification) but I have no idea how to change this. Thanks to anyone that can help me out or at least lead me in the right direction.

I would assume that they're just not compatible. When I get a mention with Tweetdeck I get a yellow light, and a blue one with Plume so I would think if a color could be changed, so could the blink rate.

I have this app called "Light flow - LED control". It basically lets you change the colour of the notification LED for each individual app, as well as setting the blink duration (not blink rate, unfortuately). It does, however, require root. Try the lite version to see if it is what you are looking for.
There is another app that allow you to set blink rate, which is called "Blink - Flash LED in your way". It didn't work as expected for me but I didn't play about with it much.
Hope that helps.

i dont think it requires root. i had it on my phone before i was rooted for the same reasons but i couldn't get it to work with gosms (i would have to disable gosms from blocking other notification apps and that messed up the sms timestamp for some reason) but it's a good app in general. our phones get most of the colors though i could never get the light to stay on for low battery.
all in all i think its a cool app but won't provide what you're looking for.

I have used light flow before, and the color support is fine. You can 'change' the flash rate on light flow, but it doesn't actually change the rate, im guessing there's some kind of software, or possibly a hardware restriction.. I've been looking around all of my system files and can't find anything related to the LED. Let me know if you find anything guys.

It is a software problem. CM7 did work better v

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:
https://play.google.com/store/apps/...yYWdlY29uc3VsdGluZy5hbmRyb2lkLmxpZ2h0ZmxvdyJd
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.

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.

LED / Notification Bar Apps

Hello i flashed eXistenZ today on my phone and i have everything running smooth except the ledsthe phones led flash too much and sometimes they are on all the time.
I use light flow to control the leds but it wont change the color or the flashing frequency.
Is there a way to see which system app controls the led bar and disable it ???
Thank you very much.

Illumination Bar (pro) is the best application in my opninion. It has a lot of settings and is compatible with our device.
I believe Lightflow is only for the devices with 1 led.

Having 3 different colors
@mrjraider does Illumination Bar Pro allows you to modifie the colors of the three leds? Like when you boot with CWM who light Green Blue and Red led except of having one single color.

nope

No it only uses the three leds with the same colour on. Only root and special apps can do this for example discolight somewere in the themes and apps section.

Lightflow now suports 3 leds, just make sure you´ve checked illumination bar in settings. For me works great

It was not working for me so I got rid of it Now I have no application installed and just using the sony settings

a lot have changed since then i flashed 4.4.2 Aopk and not im running a smooth and stable system... but the leds seem to be buggy with discolight because everytime i check "Music Pulse" the leds stay on in full brightness i have to figure this one out.As for lightflow i hadnt much time to mess with it yet ill reply when i do

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

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

Change LED notification color

Hi all,
I want to have a LED notification with Gmail. So I tried Light Flow and LED Manager from store. But both are not working.
Did somebody try to change LED color?

I was able to turn on led notification for gmail with Light Manager Pro 12.1.7, but I'm unable to change color (it's already blue for gmail).

Did you try Light Flow? If not, would you mind to try if you can?
Someone replied to my thread on the same matter last week and said it was working fine as long as you use the basic colors given by the app.
I tried to install it on a device in a shop via apk, but the damn retail demo that I couldn't manage to uninstall/deactivate prevented me from locking the screen to allow a test run (it's a feature in the settings of light flow).
Btw I got an answer from the developers of both LightManager and LightFlow and they told me P20 Pro is not fully compatible with these apps, but I don't know what "not fully" means in terms of what we can and can't do.

Light flow didnt seem capable of setting the color correctly. For instance... the led color just kind of cycled a few colors when I set a particular notificationc olor to blue.
LightManager seems to work so far... but blue is very dim.
Both require a persistent notification. Will see how that affects battery.
Edit: Annoyingly enough, after seeing lightmanager works, I decided to pay the dev for the full version... which does not work. Somehow.

Damn... I was hoping to get at least a smooth run, working basic colors and no persistent notification.
I’ll give it a go again in another store by installing light manager before giving up and going with the S9+.

I paid for the full Light Flow version and it still isn't working for my P20 Pro. Guess we gotta wait for full compatibility

I gave up using Light Flow a few months ago but tried again today, out of curiosity, and it works! I recently updated the P20 Pro firmware to v8.1.0.156 (C432), don't know if it started working with this version or the one before.
