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.

Agreed lol. Just need the devs to add the code somewhere to enable this colour

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?

LED Control

Just rooted me phone. Thanks to everyone who contributed to it!
With root, do we have control over the led color notifications finally? Or does that require more semantics?
Moto Droid's LED notifier is RGB. DroidINC has to have something similar right, because we get Red, Green, and Orange..unless they someone how have three colors in that tiny hole...

I don't understand... what does the study of words and the meaning herein have to do with LED control? Did I miss something?

What do you mean LED color? The LED flash is the only LEDs on the phone and they are one color. You can swap it out for a custom color leds and put them in the place of the dual flash LEDs but other than that you can not change the color.

Oh, let's not argue about semantics
I read somewhere other than XDA that HTC had released the Incredible devices source code which, if true, will lead to all kinds of devices-level mods. I personally would like to see the soft button backlights be dimmeable, or individual controllable for different kinds notifications, or possible a scrolling/marquee style effect so it looks like KITT is in charge ehehe.

He's talking about the notification LED on the front of the phone.
and OP there's nothing out that I'm aware of as of now.

I don't think any software modification would allow you to change the color of the notification LED at the top or the LEDs at the bottom (Home, menu, etc). However, I don't know anything about LED technology to argue my thought(s). I assuming that whatever color bulb they put in there is what you get.
Don't get me wrong, I would love to have the bottom buttons a red color to match the top speaker/camera areas because the phone would look absolutely badass but I'm not about to pry the screen off or take the phone apart to do it.

Correct me if I'm wrong, but the Dinc has at least a green and red LED for notifications. The Moto Droid however has RGB so you can pretty much make any color appear. That is also why there are a lot of options in apps like Handcent and Missed Call.

Sorry for the confusion, all. But yeah, I was referring to the LED notification on the front.
The LED flash on the back- is a bulb which can only push out white. But the one in the front pushes out Red, Green, and Orange. And with the moto droid, you could manipulate color notifications with different programs..
so my question is more of- is it software that locks those colors or hardware that does... thanks for clarifying my question-jrkrush2112

I suspect the notification LED in the Dinc is a tri-color which gives you red, green and a form of brown which looks like amber. It is not a RGB LED like in the Moto Droid.
So you already have the colors that are available.

It's most likely a mix of both. The hardware portion is the fact that we don't have an RGB LED like the droid, and software is just what options are pre-set. We will be able to change the colors for notifications, but we are limited in options.

[Q] Notification Light No Red RGB values

I broke my screen a few days ago and had it taken in to be replaced. A few hours after receiving it I noticed the LED was blinking, but in strange colors different than those I set in Light Flow. The normally white notification is now cyan, yellow is now green, purple is blue. Red however doesn't display at all, so it seems that the red portion of the RGB scale is not functioning. Does anybody know what during the screen repair process might be causing this to happen? I'm almost certain its not software related as prior to having it repaired the LED was working correctly. Thanks!

There's a kind of filter for the LED on the display, not all replacement parts come with it and it's pretty easy to overlook.

There does seem to be a blue hue around the notification light area when held in the light... So could it be that this filter was mistakenly left on the old screen, instead of transferred to the new part? Or is it something attached to the screen that can't be moved from one part to the other?

It wound up being a damaged LED light

RGB led has strange color

Hi all, i use different led colors for different type of notifications and I noticed one strange thing. Depends on color if I look the led from a close distance, it seems divided in two parts with two different colors. Is that normal?

mine does that some times i can see blue and green

A led such as the ones in the phone are RGB. They have a Red, blue, and green chip that make up the spectrum of colors... As with all things, these are your primary colors that lead to all colors. Light all 3 chips full bright and you have white.

Yes, it depends on what color is the led. Do you have any "light blue" notification's color?

Meaning? So, is that normal that when the led has to visualize a secondary colors, it is half of one color and other half of another color?

Yes, it's basically mixing different colours to produce a new colour.

Ok, thank you. This is my first phone with a RGB led, so I didn't know how it works and I wanted to be sure that this beavhiour was ok. It seemed a little strange to me that if you look so close the led with secondary color you can literally see the two primary colors close together.

Hi guys, I saw a strange thing. Phone locked, if I turn on the screen (without unlock it), if I have some notifications, when the screen turn off again the first led blink is red instead of the color of the notification. How come? I have my battery charge and the phone has full network signal.

Never encountered this issue but sometimes when I have multiple notifications the led gets confused and flashes different colors for the different notifications. For example Emil will flash red but text is blue so it will flash red and blue.

Edit.

I don't have any red notifications, only yellow and green. I don't understand, what could it be?
Sended from my Samsung Galaxy S7 Edge Gold Platinum

I tried to reset default values, but the only thing that changed is that the color of led the first time is blue instead of red and the it start to blink with the right color of the notification. I don't know what to do.

In that case, two colors for two type of notifications, what is the color that will be displayed? The one from last notification received? Anyway from close distance, the mixing of two primary color in order to "create" a secondary color is really visible.. I hope is normal.

Yes, it's normal for S7 Edge which has a really low quality notification LED which seems to have been produced with an inferior technology. It can't even display the white color (displays a purple color) due to the cheap LED "lens" design which does not mix colors well. My former LG G2 had a great quality LED which could display any color, including pure white.
However, just be thankful that there is a LED, many manufacturers like Motorola chose to omit it (really stupid). You can just use primary colors (Red, Green, Blue) those are displayed quite well.

This is a very nonsense thing. A phone like this should has a high quality led. Sometimes Samsung just lose itself in a glass of water.
What about the notifications colors priority? Does the led use the color of last notification received?

By default the S7/Edge only displays an infrequent, intermittent blue light if you have any notifications (doesn't matter from which app).
If you use the Light Flow application, you can customize and display the color of the notification with the highest priority, or cycle colors of all notifications, etc. But...There are quite a few issues with Light Flow on the S7/Edge. Most are fixable, though.

On my phone is not like that. My led usually display the color of the last notifications received. That's why I want to understand if this is a normal beavhiour.

LED Notification Colors

I am still new to this phone.. but i'm trying to find out if the LED light allows for more colors than just Green and Amber ?
I had tried LED Light Manager and it didn't seem to make other colors..
Now that i'm rooted and running Viper ROM.. I see that they only have options for "apps to use amber instead of green"...
so does that mean that is the only color options?
Thanks!

Right.

It's not like the Samsung galaxy phones that use a red, green, and blue led and basically mix the colors to create any color of the rainbow, the HTC's have just an amber or green LED and you have the choice of one or the other or neither

yeah i think that is what i was used too... had the S4, S3 and also the Nexus 5... all had various colors for the LED.
my biggest gripe is i wish it was a larger and brighter LED.. but overall still a wonderful phone.
