LED Notification Colors - Nexus 7 (2013) General

Looking for insight about the colors that the LED light can display. Not sure where it would be documented, and Light Flow only shows white.

Nexus 7 only has a white LED:
Racer Of All said:
Q: Is the notification light RGB? Why can I only have it flash white?
A: The software is reporting that the LED on the Nexus 7 is only white (my explanation here). This means that because it's missing the other primary colors it will not be able to flash anything but white.

Why not check the kernel drivers to see if it has support for something else?

Unfortunately, I am not a kernel dev and don't even know where to begin. What we do know at the moment is that as far as stock goes the Nexus 7 can only show the color white (which is stated in the link on the quote).
Perhaps it is an RGB LED and it was disabled at kernel level, however I can't see why Google would do such a thing.

Hmm maybe they kept white just that so they can keep the thing low (even though LED's are cheap)

Probably. It would have been nice if they would have 'upgraded' us to the multi-color LEDs and just passed along the added $0.04 cost to us...

I'm hoping that it's RGB.
If you look closely at it, it has a slight pinkish hue to it. It's the same way with my Galaxy Nexus (which does have RBG). I'm guessing it's because all the colors are turned on and the mix isn't perfectly even.
I could be wrong, of course.

LED Notification Light - multicolor capable?

So the specs noted that the LED notification light was "tri-color" but none of the reviews that I've seen have indicated if it's a true RGB LED capable of producing multiple colors. I'm so used to having different colors for different notifications on my N1, I'd hate to be limited to 3 colors on the Atrix.

Actually... All I've gotten is green.
blackberries also have a multi colored led but always shows red. Fortunately, there are apps (free and paid) that will let you tinker with it.
sure hope there will be one for this phone.
I think it has rgb, and then a white led
Its got a white led when charging, green for notifications, blue for calls, and red when theres a low battery. Use the app 'led tester' off the market to test the leds, its a pretty neat app. I like 'led disco' because it flashes all the colors and goes through them all. With the red, green, and blue led you can produce any color you want.

Uhhh. No. Those facts are not true. Had the atrix for 3 days now and I've only seen it shine green. No red no nothing. And TRUST me I've been tinkering with it.

Yes, it doesn't work.
I have an atrix in my hand and I have seen 3 colors:
1. Green for messages and charging
2. Red for low battery
3. White - can't remember the condition
I have not seen blue. The Bravo does have blue though.

How in the heck did you get it to say low battery? O.O! You really like to abuse your gadgets don't you?!
I've been able to change my colors. Not sure to what extent you can though. I had pinkish for SMS but changed it to blue.
I always run my stuff down until it dies once every couple of months - i did the Atrix early.
So far battery life is great - i played with it all weekend and it is one solid phone.

Yep. I tried running it out of battery but I got bored and decided to let it get some charge by the time it told me it needed it.

Exactly. Even when I plug in my phone I don't see any light go on. :S
I'm using GoSMS which has an option to change the led color of it's capable.
I was able to see blue when connecting my bluetooth headset to it. It only flashes when it makes the initial connection.
So far I've seen red, blue, green, and a purpleish color. I came from my BB with the BeBuzz app, and it was easy to tell which one of my contacts were calling/texting me from the colors I had assigned.
I was able to use LED lights on Touchdown app..Blue, Red & of course Green.
Okay, let's try asking the question a different way to get an answer we all are looking for.... what FREE app works to change the color of the LEDs and isn't an add-on or skin to SMS or Email? I'm looking for something just like Blink that actually works for this phone!
EDIT - Well what do you know, it DOES work as long as you read the damn instructions! UNPLUG the phone.... click Menu > LED Manager > choose a color > check to test color > TURN OFF SCREEN ON PHONE...... all six colors - RED, GREEN, BLUE, YELLOW, PURPLE, and TURQUOISE all work when you follow those steps! Pretty awesome
<== can be an idiot sometimes....

Mine was red when the battery level dropped to 10%.

Has anyone actually used the alleged "display callibration" software?

And if anyone has, can you tell us A: what parameters it actually lets you change, B: do these changes apply universally or only in certain apps, and C: if this is actually supposed to affect the physical properties of the display in some way (in the way that the contrast control on an LCD TV might), or if it's just doing a Bravia-like trick and messing around with the pixel values?

I don't really need it, but since lots of people talk about it - i'm curious if it's real, because nobody provided any screenshot/details of this feature.

That's prolly the one and only screenshot that got out on the web. A real test would be great!
Like make a screenshot with unaltered settings then next is try to adjust it and let us see how big is the difference.
I repeat my earlier question: does anyone know what this software actually does? For example, suppose I'm looking at a screen full of white pixels (red 255, green 255, blue 255), and I've used the software to push the white balance towards red; what does that do? Does it actually change the physical display characteristics of the screen, so I'm now still looking at pixels that are red 255, green 255, blue 255, but the screen has changed the way those RGB values are displayed, (i.e. red 255 is now brighter than it was and blue 255 dimmer); or is it simply hacking what is sent to the screen so that what was originally r255g255b255 is now r255g240b220 (or whatever)? And does this apply universally, or is it a subset of Bravia? And is there anything that can be tweaked other than the three controls we've seen in the screenshot?

That seems unlikely, but it's just possible that it might allow you to tweak the display in the same way as you can tweak the red, green and blue "drive strength" on an LCD monitor.

Does it have a bluish cast/tinge?
too me it seems that the screen ist brilliant and well balanced (colors). there might be better screens, but this one is awesome...
it's like a mercedes sl...this car isn't the best car, but who wouldn't love to drive it?
but maybe i'm the wrong person to judge about the screen, because i'm upgrading from an htc hd2. and this screen is really old (but i like it, though).

[Q] Do I have a broken notification led? :(

It doesn't work. No matter what app I try it just doesn't go off. There is also no display option to turn the led on or off.
Anyone familiar with this?
Using stock 4.3? Download lightflow from play store and it'll work.

Then why are you asking if you have a broken LED? It wouldn't make a difference if it lights up or not if you thought the feature was useless. I personally like it. Comes in handy when I'm not in my room and leave my phone there and then come back to see the LED blinking.

Im having this issue, but mine hasn't worked since cyanogenmod a couple months back, on carbon or PA it didn't work. Now on 4.3 and doesn't work. Though on Carbon the charging notification still worked when plugged in but lightflow or other apps didn't.

The feature is really useful if you put in a bright led, one that a normal human can see when there is even the slightest hint of light. Not one that only works in total darkness.

Notification LED dull and not RGB?

Hey guys...one of the most used and important features in any Android phone for me is the RGB notification LED.
The S4 and Nexus 5 had great ones...I'm a little worried about the very dull one on the S5.
I cannot get Light Flow to work at all...and while I know the S5 is really new...just a little troublesome...

It does have an RGB flash, tested colors with LED Tester app, but haven't set up Lightflow, which is often rather complicated. You may restart your phone after setting it up and see if it works properly.
I guess it's duller because the plastic over it is thicker due to the IP certification (?), now why isn't there a cutout for it like for the sensors is beyond me.
I find it bright enough, far better than whats on HTC phones. I can also see it from a 45 degree angle, the one on the s4 was better still but not complaining as it still does its job

Led tester works perfectly for me in all colours. Be warned if you get an incoming notification whilst testing the colours, the light will revert to the notification colour until you click on the notification and reset the led.

All off the LightFlow app developer's websites/servers are down. Could you please give me the run-down on what you did to fix it? (I'm having the exact same problem).
I agree the LED is VERY dull, my sister just got the LG g2 and the led on it is beautiful very bright and vivid colours.

Notification LED colors

I've been looking for an answer to this but I haven't found any good one with a clear "NO" or "Yes".
Is it RGB, multicolor or some technology with more colors? Has someone tested it with light flow to see if you can control it or it is actually a RGB led but the software just let you use 2 of them for some reason?
I'd like to have at least 5 colors... It is weird to me to see that it only has green and red. To be an RGB it only lacks the blue one, which is really werid to me. I'm planning to buy the phone and since I had this LED on my Galaxy S3 back in the day I can't be without it.
Doesn't seem RGB to me, so far I have seen green and red from the notification LED.
Couldn't get another color to display with Light Flow app (I'm noob with it tho, I just installed to reply to you)
Ya, I can't get light Flow to work either....all I have seen is Red and Green. Someone said orange but I have yet to see it.
Red and green...that is all I get also. But it does work! Some do say yellow also but I am not sure when yellow shows up. I have not seen yellow yet.

If it's got red and green, you can get orange. It's just probably not used in the ZTE software anywhere.
And RGB notification light isn't a fancy LED light any phone I know if, it's discrete R, G, and B diodes. Which is why you can really only get Red, Green, Blue, White, Yellow, Orange, and Purple on any phone.
Thank you for the information guys. I'll keep that in mind.

I think they actually have the blue diode, but they don't use it. I wonder if someone can get it to work along the other 2.

all three colors are showing up under /sys/class/leds, so it must be there. I'm not sure why it's not able to be turned on. I was able to get red, green, and orange to show up.

So it is definetly there right? Or maybe it is just a generic class for leds and they only use the ones they need (red and green). Would be nice to check if they can be activated via software in some way.

They shouldn't show up there if they aren't actual hardware, as those are created at runtime, I believe. I tried writing a value to the brightness, but it wouldn't let me (terminal user isn't part of the "system" group).
The LED testing app I was playing with couldn't activate it. So, no idea why it's not working.

Does it require the blink file to actually turn on though? I thought you just turn it to "on" with the brightness file? It still seems odd to only partially create the class (just like it seems odd to only have a RG LED if that's what they truly did).

Only RG confirmed. Bummer.
Wow.. Disappointing..
how can you fit a flagship device with top notch display, cpu and chipset with a crappy RG led for notifications?
i honestly can't belive it and i hope it's just a poor software use of the existing hardware...

Well, it is a small annoyance, but this phone was half the price of my other choice (Note 7). Also, it hasn't exploded, so that's a plus. It has better screen and audio than OP3, which was my third choice. So, I'd enjoy more notification light colors, but of things that were cut to save me $400, I'd vote for simpler LED light while keeping gorgeous screen and great sound any day.

Blimey - that's quite extreme! I personally only care if there is an led (one colour is fine for me) as I'm only interested to see if there's a notification - after that I pick up the phone to see what it is!
