Front and rear LED's? Are they both RGB/full color?

Does the front LED allow you to choose any color (like the Nexus 4, Galaxy Nexus, etc)?
Does the rear LED allow this too?
Do apps like Light Flow allow you to properly set different colors for different apps? Can you use both front AND rear LED's? Thanks!

I can only speak for stock:
You cannot choose the colors for each event, but you can choose which event you want to blink. The colors for each are preset, most are green.
The rear seems to be one color, but only works for:
Incoming Call
Alarm
Ongoing Call
I believe Light Manager (nonRoot) allows you to change the colors to anything you want (on the front). The back I believe is only hyper white. It has a very nice looking pulse to it. I believe people trying light flow could not get the app to detect the rear LED. Someone else can confirm.

using light flow i got the rear led to light up but it does not flash like the front so like when you get a message the front led is flashing and the rear led stays lit up and its only color is the hyper white

Front is full RGB color. Back is just white. You cannot globally change the color for specific notification types. You can however change the color for notifications from specific contacts to colors like purple, yellow and pink (and more). It boggles my mind though that you can't change the color globally. Hopefully a custom ROM will add that.

Some have reported inconsistent results with Lightflow. Also, I'm a battery nut and hate having extra apps running for such specific things like controlling the LED, not to mention a persistent Lightflow notification when it's running gets under my skin. Yeah I've got a bit of OCD when it comes to my gadgets heh.

Light Manager is working 100% accurate for me. And I'm not even rooted yet.

Can anyone confirm that the rear LED flashes only once then stops? I couldn't find a setting to make it flash more than once.

This is working perfectly for me as well. you have to disable the built in notifications in settings but after that it works like a charm. No constant notification and no battery hog

For the time being looks like Light Manager is the answer.
For a few versions now the custom ROMs for my Gnex have had their own LED notification setup built in. You can set any color for any installed app, and it was always ultra reliable. So once the development really kicks in for the G2, I dont think we'll need any external app for it anymore.

This is all good info. I don't like stock SMS apps because I have more options with third party like GoSMS but sadly I couldn't get it to access the notification light. Very weird considering every other phone I've owned had no issues there.

How you set the Light Flow to use the Rear LED in way you describe?
Front LED works perfect on my LG G2, but i can't set the rear to light up using Light Flow.

This; I'd like to twiddle the rear LED too, although I know it's limited.
Also, has anyone gotten the Camera Flash to work? So far I haven't gotten it to work, but the front LED is working fine.

Can anyone please tell me how to configure rear LED in Lightflow ?
I am not saying step by step but please tell briefly. Thanks

Backlight control on the LG G2 (root users only) with their dynamic file paths. Select button-backlight1 and button-backlight2 in the settings menu to enable each part of it

[Q] Note 3 LED Notification

Hi there,
I have SM-N900. I just installed Light Flow LED for the LED notifications.
Q: Is it harmful to set the app to blink the LED in the fastest mode with 100% LED brightness ???
Q: How much battery will be drained for this settings?
Thanks

but what is this application if the notification LED 'already in the system?

I don't like third party apps, but the major problem I have is the non customizable blinkers. I want the LED light to blink fast for the notifications

I installed light flow as it has a feature to blink led when the screen is on but that didn't worked. @asus_boy it does effects the battery life.

There is no harm in letting the LED work. I've been using Light Manager ever since it supported Note 3 and nothing have happened and won't. A LED is a pretty solid kind of hardware, it really takes a lot for it to break. The only thing I can imagine to break it is if you make it even brighter than it's supposed to be, and you can't do that with Light Manager. So, as long as you don't crank up the voltage you're fine.
Hope it answered your question.

A: Same as any light source, Increasing the Brightness and Increasing the time it is on, Will wear out the LED, Will you see the effects, Possibly not! LED has about 10 years life span (EASY) with around 30,000 - 100,000 hour depending on the LED type.
So to answer your question in Short - Yes it will cause harm in the long run, But nothing you may ever notice in the period you have the phone.
Q: How much battery will be drained for this settings?
A: I could honestly not tell you, Depending on the number of notifications, the time the LED is on for etc.
Will all add the possible lifespan of the battery before a charge.
I use the same application, and i have done since day 1 owing , I can easily get a full day out of my device, Heavy usage. Lots of notifications, Lots of game play, Display time and heavy CPU Usage.
Personally i think you will be okay

Thank you very much for your kind replies.
Thanks

LED color ?
i set the LED color to yellow with Light Flow LED, but the light is not as bright as when it was on red or green. does anyone experience the same thing? (sorry for my bad english)

I think it's LED color mixture wrong try pink and purple they look same

Notification LED issue

Hi, I have this lovely phone, Note 4, but even with all the functions, there is no way for me to turn off the notification charging and charged light.
I have installed Light manager on the phone, it works for all other apps, but even though I have removed the charging and charged LED function in the app they still light up with the Note's standard red and green led....how can i "kill" these LEDs ?!?

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.

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?

They also ****ed up the battery life on this update.

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.

Notification LED way too dim.

Went from Note 3 to Unlocked S8 and I rely a lot on the LED. The Note 3 was nice and bright. Not so on the S8. I cannot see if from across the room. Light flow does a good job of giving me the colors I want and I rooted the phone. So does anyone know how I can go in with a file manager and change the code to make the LED brighter? Thank you in advance!

I am at work and didn't have time to check my phone, but in accessibility settings on iPhone there is an option to make flash light blink when there is a notification. See if S8 has anything similar.

Hello, I installed LightFlow to control my Galaxy S8 led color.
What should I do to reset the colors of the led to the factory color and brightness ?

you have to uncheck Samsung root modus in light flow settings. That bring the LED back to original brightness...... at least that helped me.
Unfortunately, the S8 LED can only display very few colors correctly.
