RGB led has strange color - Samsung Galaxy S7 Edge Questions and Answers

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?

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.

[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

LED wrong color

Hi
somebody recognized that if you get a WhatsApp Message (group message) and the stock color white is chosen, the first 1,2,3 times the LED blinks Red till it changes its color to white?
is there a fix for it?
You at least get red and white, my led only shines blue no matter what i set lightflow to.
That is a little worrying. On mine it's similar to OP's description. I have read a few other reports. I was/am hoping software issue, but if its different degrees of severity on different phones it sounds like a possible hardware issue.. I wonder how common it is, I have read some reports but not many.
Seems to be a device default beavhiour. http://forum.xda-developers.com/showthread.php?t=3362364

Hi guys, I noted another thing. I selected I white led for notifications, but it always blinks with a purple one. Until now I never saw the white color, how is that possible?
Inviato dal mio SM-G935F utilizzando Tapatalk
Same here. Instead of White it's an light Blue. I tried an app to test the Led Colors. Even if I choose White in this App, it's light Blue too.
Same here. Very strange.

Same here. Seems almost like the LED isn't physically capable of true white.
Remember the LED on the old S3? It was awesome!
I wished there was an option in settings to set the LED light for individual apps.
the white color does not exist,the default led is blue..so..the white will be converted to blue

No, the LED is capable of generating multiple colours (using something like Light Manager), but you never quite get true white. Mine appears a pale pinkish colour when I select white.

Exactly. The software is bugged,a led can emit any color.

Notification LED dimmer after the APD1 update ?

Has anyone noticed this ? After the APD1 update, the notification LED is quite a bit dimmer. I tried upping the screen brightness, thinking that it may obey the screen brightness settings. No luck. This really pisses me off, since I rely on that LED, given that the AOD feature does not display most notifications.
dude did the auto-restart issue solved under the new firmware ?
Same for me, notification light definitely dimmer, a shame there seems to be no apparent settings to adjust this.
I didn't notice that. What kind of led color is dimmer?

My LED doesn't appear to be dimmer after the APD1 update, though I've really only seen blue so far.
What colors are appearing more dim on your device?

Good question and idea. It's the green color. I will switch to other colors if those are not dim, maybe red.

The green LED just got activated on my phone. I think it's just as bright as it was before the APD1 update.

Just did a test again: the LED now obeys the ambient light sensor, in bright light it is bright, and in low light it becomes dimmer (you can try by covering the sensor). Same with the AOD, as someone reported in another thread.

Under sun light the led is barely visible. Violet color in this case.

I have the "dimmed green led" issue too. APD1 here. Interestingly the first couple of activities after a full reboot for the green color are bright, then it dims... I thought of a faulty led at first but now I know I'm not alone.

I confirm that with a medium light the led is almost visible [emoji19]

Ok. I can confirm that the led now uses the ambient light sensor to adjust brightness. Weird but true

I don't see this adjustment. In a bright environment it is almost visible. At least on my phone. How do you say that it use the ambient light sensor?

Adjustment is not based upon screen brightness, which could lead to errors as screen brightness is only refreshed with phone unlocked. If you receive a notification and there's light falling directly on the ambient sensor while screen is off you'll see a bright led. If you cover the sensor (with screen off) you'll see a dimmed led. It is worthy to note that this adjustment is made only at notification arrival and not after. So if you have the phone inside a pocket you'll always see a dimmed led even if you take out the phone in the sunshine. If you have the phone out in the sunshine when notification arrives then you'll see a bright led.
I have thoroughly tested this and it's how the system now works (at least on my phone).

I get it, interesting but I don't understand why it works only at notification arrival. Anyway if your phone does that so the other phone must do that too. P. S. What is exactly the ambient sensor?

Confirmed its controlled via Light, so rules apply the same as OLED / Always on Display
As for the battery life, to when did you update?
People have complained about battery life, But i am yet to experience this issue everyone else is.
With that in mind, Linux is a rather complex system, and has some cleaver memory management utility's
(it does not operate like windows, Close down your apps to free up RAM, Linux does this on its own)
So keep that in mind, Then you performed a update, This no doubt a few settings to the kernel have been changed, Or even a update / patch.
So any information its retained about applications, Ram and process memory will / SHOULD be ereased and re-done
and the behaviour of the kernel is different.
As a result of this, you will notice a increase in battery drain for the first few days.
You can apply this same logic and method to Flashing Custom ROMS.
You have a Version of a customer ROM (For this example V1.0)
The developer releases V1.1 With some very minor adjustments
To ensure the running of the ROM, you wipe the device and start from Fresh.
WOW after installing this ROM am getting MASSIVE battery drain
(But give it 2 days or so and you will notice it will settle)
(After the Kernel has collected enough information about running process, whats needed whats not, what you keep opening and closes, What is needed to suspend and keep active)
The list goes on.

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.

S7 edge notification led problems

So i bought a new s7 edge and i saw a little black point in my notification led. Also the colors of the led are pretty akward, especially white(looks more like a pink). Do you have the same problems as me?
