[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:

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.

[WORKING] Lenovo P2 (rooted) custom led notifications Stock

Hi,
to get custom led notifications you need a rooted P2 and Light Flow (find it on google apps)
I want to thank Andrew Moore (Light Flow)for taking the time to look at this with me and pointing me in the right direction
New (upcoming) version of Light Flow supporting "large" numbers for RGB led brightness will be available soon. Otherwise you may want to edit the backup file as per this post:
https://forum.xda-developers.com/vibe-p1/how-to/led-fix-custom-roms-t3569108
1>Disable led notifications on you device (Display)
In Light Flow
1> enable Direct mode and root
2> enable rgb led
3> set the rgb brightness to any the following for your notification:
Bright red:13631488
Pale Blue:6316128
Crabapple Red (pink):11796512
Orange:12607488
Green: 35840
Cyan Blue: 32896
Sea Blue: 8388
Dark Purple : 3876477
Before Andrew put me in the right direction, I tried different brightness levels with mixed success. As you see from above, the numbers have no logical sense (at least to me).
If you do find additional colors, please post them in this thread.
HAPPY CUSTOM LED NOTIFICATIONS EVERYONE

Here are the "reference colors"

Works also on custom roms.Thanks for the guide!

Thanks for making the LED work! But I'm stuck at the brightness levels part... In the notification settings per app, under the light settings, I can only set 4 numbers and you give a whole lot more. What am I doing wrong?

As I said, light flow at the moment only supports 4 . Andrew (the maker of light flow) will update the app asap. If you are in a hurry., use the backup/modify./restore method mentioned in the first post. Just change the brightness level. It works.

Hi, any chance to set the red color too (the red color the LED shows when charging)?
Found it in the first post Sorry!

Useful 10x.

Thanks for the tip and tutorial, I got a bit confused on where to set the RGB colors (in the individual notifications) but it's working well now. Also the battery charged threshold was set at 90% by default so it popped up as green when I plugged in at 92%

It is only working in Test for me. Can someone send détailled settings?
Thanks

Did you make sure it was active? If it is you'll see a notification in the pull-down list.

This is really cool, definitely will use a custom Rom because of Light Flow.

Working thanks

Could someone tell me where I insert the RGB values?
I have a rooted Lineage 14.1, but all I can select is one colour with RGB enabled...
There is only one colour available per application, ie e.g. Signal has blue (which works), agenda as well, but Gmail has black... And that's not showing of course
Edit: I edited the settings manually and imported them again as suggested in the opening post, we'll see how that goes...

Does it work with free version of Lightflow?
https://play.google.com/store/apps/details?id=com.rageconsulting.android.lightflowlegacy

Works for me with the legacy version. But there is also a "light" version of the newest release.
Currently, I see heavy battery drain due to light flow; the device never goes to sleep. Maybe, this is different with the light version... I will try.
Edit: same battery drain issue with the light version...

This does not seem to work with the latest version of the app(I even bought pro). I followed all the steps but it never works. Is there something I'm missing? after enabling rgb control i setup a notification and in the setting's light tab i enable the light and set the rgb LED to solid and set the color to one given in the first post(none of them seem to work). I then use the test button but LED does not turn off(tried both - turning screen off and keeping it on). Any Help?

@Uibon
Me neither.
Edit: Legacy is working, but only when screen is off. I'm rooted of course rooted (Magisk) and I have the "screen on" option ticked.

Those of you who reported it working, does it work when the screen is on as well?
Edit: Missed calls, incoming call and other things related to the system is working when screen is on. With Textra (and other apps?) it only works when screen is off.

Thanks for the instructions and links.
I bought the app (Just Rs 10).
Cant be more worthy purchase.
All working good.

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

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.
