Notification LED Multicolor (App to toggle blue+green+amber led included)

I've written an app that can enable and disable the blue led with a toggle. I would like to know for who this works. Please test it and tell me .

For some reason my Desire went buggy and crashed at some point. However something amazing happened.
Contrary to popular believe, there are more colors than red, green and orange. My Desire's LED flashed blue and purple. Now I searched the forums and could not find any topic that confirmed this, nor on google, so just to let you guys know .
Next point on the list is finding an application that can tweak them

EDIT: Seeing the recent activity in this thread, I want to tell you this app was written a long time ago. It does not function on any recent roms. There are loads of other apps out there that can control your led.

Gheh, it only showed for like a few seconds, then the phone restarted, I will try to replicate the bug, but I expect I will be unsuccessful .

Interesting. I got my Desire yesterday and installed the Touchdown app for corporate connectivity. In TD's settings you can customise the LED behaviour to select different colours (beyond red, green and amber) for different events. Tried it and it just flashed green, but why have these settings if there's not a way to do this...interesting

I have been able to replicate the bug. This is how I do it:
1. Turn on Bluetooth
2. Receive a text message while charging
3. Disconnect from charger
4. Turn off screen
5. Reconnect to charger
6. My led will glow purply
7. Disconnect the phone from the charger
8. Led starts flashing blue, orange and purple
9. Phone reboots
Taking pictures as we speak

I've added the images. It was too hard to take a picture of the blue color. But at least here is purple.
PS. images are in the first post
EDIT: Also, I should add, I have been unable to duplicate the color for a second time. No idea why it happens. Just happy I was able to get these pictures

i did what you said. no special colors but strange things happens. no reboot

Re: Notification LED Multicolor (Picture of purple included)
Looks like the desire does some how support multi colours :S there must be a way to enable this fully within the codes. I will be donateing if the devs can get this to fully work

I have tried and tried and I have been unable to replicate this bug from this point on. I'm so happy I was able to take the pictures. I think it's because of a semi-faulty flash that I have this bug. Even though the randomality of it suggests it might be more of a hardware bug. We do however now know it has a blue led too. So cyan and white should be possible as well. I just wonder, why go through the trouble of a adding a full multicolor led, if you are only going to use 3 colors of the possible 7.

there might be something as simple as a voltage problem.
most leds will change color when you increase voltage and/or overload them.
the first few times you won't see any damage, but eventually the changing color might be permanent and then it's just a matter of time before the led just brakes.
so there is a change that it's not multi color, but the phone just overloads the led while crashing.

When I looked down the headphone port I could clearly see the red and blue led burning. I do really think there is a blue led in there.

Haa nice one mate

Well we know there is a Red and Green led for definite so having a Blue as well means we have multi colour. Now we just need a way to use it
There's no way that type of colour came from overloading the phone as when an LED overloads it just blows, it doesn't change colour to that extent.

This should really be moved to the dev section, let the guys play with it, i dont think too many devs trawl through the ****e on the general forum, with questions like "how do i make a call on my phone".. lollol
Start a new thread on the dev section, im sure this will be picked up by one of the wizzes

Heh, I'm sorry guys, but we already know there's a BLUE led inside.
This LED works a bit differently from the other LEDs, however.
Theres no need to do advanced tricks to show the blue LED, you
can easily enable it:
echo 1 > /sys/devices/platform/leds-microp/blue/brightness
From within a terminal emulator.
the blue LED is, however, missing the 'blink' property, as the Green and Amber LEDs do.
And yes, it is also possible to turn other LEDs on at the same time, so you can make purple by enabling the BLUE and Amber LEDs.

Then can we not just simply integrate that command into our applications for use of the blue LED?

[Q] Notification LED

So I was playing around with lightflow on my nexus 4 and I noticed that the red LED is kind of prominent when the notification light pulses when I have any color selected with red in it. There's a red glow at the top of the notification light when it pulses, which makes blue half purple, yellow half red-orange, and white pink/purple. The picture is kind of bright, but you can kind of see what I mean (it's supposed to be yellow). It's a lot more visible in real life... Does anyone else have this too?

Looks yellow to me brotato.
But yes, I think it's normal to get glimpses of other colors. Happened on gnex and gs3 too.

How do you even configure the LED I couldn't find a way to do this (never had a phone with notification LED before)
In fact I haven't seen the notification LED at all, I can't test SMS messages because my Micro-SIM isn't here yet, but all other kind of notifications had no effect.
Where do I find the LED settings
EDIT: Ok, It seems like there is a notification if I receive a mail (gmail), but not for all notifications. Is this normal?
(If you can tell me how it works I can check if I have a red glow)

Use light flow, download from play.

Slightly topic related question. (apology for slight double post - question sits better here - not worth another thread)
Q1 : When charging I have no lights/led indicators illuminated (on both stock and aokp) - is this the normal? - intended behavior?
I'm used to HTC/Samsung, that tend charge at one colour (amber/red) and then display another colour when full (green). This would seem sensible to me, so that we ensure that we don't over charge the battery and over heat the phone?
Q2 : Another favour to ask: can someone please post a close up picture, of the two Nexus 4 USB cable plugs, as I've managed to confuse several USB leads and don't know which came with the Nexus, which I may need for an RMA return?
Thanks in advance

An RGB LED is basically 3 LEDs crammed into one housing. It's just like a pixel on your monitor, but larger. If you were to zoom in on your monitor you would notice the three individual colors. It just so happens that the red part of the LED doesn't diffuse throughout the housing as well as the other colors do.

I see, it's done using an app.
I can see a small red glow at the top (I guess) but it's really small and I wouldn't even have noticed without this thread. (Maybe it's because I am red-green colorblind, but I don't think this has a great effect here)
BTW: Is there a more advanced possibility to control the LED in Cyanogenmod or is it a good idea to pay for light flow (I'm especially interested in support of steam)?

Yes, by default there is no LED notification of the charge status. You can use Light Flow (including the free version) from the Play Store to add this behavior, as well as controlling notifications for all sorts of events (not just LED notifications -- sounds and vibrations, as well).
You don't need to worry about overcharging the battery, though. There is a protection circuit built in that prevents issues of that sort.

CM allows you to set colors and flash rate per app, Lite flow allows this too, Lite flow (paid) allows you to add additional apps beyond the standard ones (Gmail, SMS, Facebook, etc).

thanks, but I wasn't able to see any attachment? *confused*?
EDIT: I can now, XDA/browser issue, seen it now - so resolved and thanks

I'd suggest you try out the lite version of light flow first then decide to buy it or not. It's worth the price AFAIK!

Activate your Nexus 6 LED Notification Light

Hello Everyone,
I'm sure this has been covered before and a lot of you already know about or have already activated your Notification LED on your Nexus 6. This thread is for people who did not know about the LED or don't know how to activate it.
So, the Motorola Nexus 6 has a RGB Notification Light. It is placed inside / beneath the top speaker. Motorola / Google decided to disable it in favor of the Ambient Display feature. Why would they not still leave it available as an option? I have no idea. It is pretty easy to activate it though. Here is what you need to do.
1. Your Nexus 6 must be rooted.
2. Download Light Flow Lite (FREE) on the Google Play Store.
3. In the Light Flow App, go into Settings, then Device Settings and Root. You must select the following options: Direct Mode, Root Mode, Run every command as root. If all three of these are not selected, your LED will not work.
4. Now just go into Notification Settings in the Light Flow App and you can fully customize your Notification Light.
For example, I have my Notification Light set to turn red while charging and green when fully charged. When I unplug my phone, the light goes off instantly. I also set red for missed calls, green for text messages, and blue for emails (Gmail). This is sufficient for my needs but you can also setup specific app notifications as well like Facebook, Twitter, Snapchat, etc. You can even set the cycle timings for when you have multiple notifications.
The only issue with the Notification Light in the Nexus 6 is that you can not make it blink. It will stay on / solid until you clear the Notification. I don't believe this will effect battery life too much, especially being Light Flow gives you control of the brightness of the LED. Also, Light Flow gives options for other various colors such as orange, purple, white, etc. I have only gotten Red, Green, and Blue to work so far. I am currently looking into this.
This method works whether you are stock or even if you have a custom kernal / rom. There are quite a few custom roms for the Nexus 6 that activate the LED as well.
I have decided to post this because when I looked into activating my Notification Light on my Nexus 6 I came across a few methods, and this is the only one that worked.
Also, most importantly, all of the guides / people I have talked to about activating the LED on the Nexus 6 that direct you to Light Flow claim you need the paid version and you do NOT. If this use to be the case it is not anymore. I have full control of my LED and I do NOT have the paid version of Light Flow.

There are dozens of ROMs to download that already have the notification light working... So I guess this really only pertains to those who buy a Nexus and wish to remain completely stock except for these mods? In which case, same a custom ROM but they are doing the mods themselves.

I agree. I have had my Nexus 6 for about a month myself. I have not tried out any custom roms yet. I like keeping it simple / stock. I just wanted my Notification Light is all. This thread is more directed at stock users I guess.

I can only get Red, Green, and Blue colors though.

Same here. I believe that is all the light is physically capable of producing. I think that is the outcome regardless of the method used. (Light Flow, Custom ROM, etc)

Best app to control notification light?

Just got my nexus today! Playing with the notification light and doing some research. Seems light flow and led blinker cause the ambient display to come on randomly. I also tried light manager but that gives a persistent notification in the notification shade which is annoying. Any suggestions?
Sent from my Nexus 6P using XDA Free mobile app

light flow works great for me (I turned off ambient display, as it doesnt work very well even without light flow installed). You can also, in light flow, turn off the switch screen option, which will also help with ambient display.
as for the persistent notification, that is a marshmallow issue for the time being, the light flow developer explained it quite nicely (ill try and dig it up).

Yeah, I mean I just got the phone today but ambient display is a little wonky. I thought it was supposed to turn on every time I take my phone out of my pocket, but if doesn't.
But where is this screen option in light flow?
The persistent notification is only with light manager. I don't get one with light flow.

give it time, on its own, it will come on also
In light flow, I am not sure if it is on by default, but if you go to main settings > general settings, there is an option for device admin, if that is checked, you will also have an option to switch screen on (which you can enable/disable on a per notification basis) . You could if you wish use this option instead of light flow, it may work better for what you like as well.

LED Notifications

For some reason the notification LED doesn't function on my XL2. I installed LED Blinker Pro and it works like a charm. Just thought I would share incase anyone else is having this issue.

Settings, apps and notifications, notifications, blink light. It's off by default.
Now go get lightflow and go nuts.

I did that and it still didn't work. That app solved the problem though.

Have you used light manager? And if so which do you like better. Im using Light Manager but that app you showed looks more polished.
Also have you noticed this time around the phone has trouble making some colors. Like yellow looks kinda yellow/green and white is kinda blue/white

Light Flow works. But it seems that the built-in notification light triggers first overriding Light Flow. For example, if I get a text message (fast blue blinking light set in Light Flow), I get the slow, white stock notification. If I unlock and then immediately re-lock the phone Light Flow kicks in with the set blink/color settings. I've tried to disable the stock light notification, but if I do Light Flow won't work at all.

Light Flow didn't work well for me.

So is this just a software issue that could be addressed by Google in the future?

My 6p was the same way when I first got it.... But once they built in led notification into the settings of the roms I then got more cookies and very crisp distinct colors too..... Im sure the custom roms and kernel will fix this and the OLED panel color issues

Light Flow works perfectly for me.
Enable the light in system settings.
Disable it when there is an option in specific apps.
Make sure it has the right permissions.

I installed the New Pixel 2 XL Launcher on my OG Pixel XL. My light stopped after installing, so I had to go to the launcher settings (long press blank area on home screen, Home settings, Notification Dots, Blink Light) and turn on the light in there to get it going again.

Yep, that's how you get the LED to work. It's really wonky and idk why they buried the setting in that spot.
