Arc LED Notification light.

I thought the Arc had a notification light on the Battery charging light but cannot find the settings in the menu & when i get a message via gmail, there is no light just a notification in the bar??? Does anyone else get a flashing light if so any idea where the settings are.
Cheers

Just did another test & the led light does flash. But when you press the power or home key (which displays the lock screen) the led stops flashing which is silly as you can easily press the home key in your pocket.
Is there anyway to leave the led light flashing until you swipe & unlock the phone, or to disable waking up the phone by pressing the home key.

i think Led always stop flashing after the screen comes on. This was also on my nexus. didn't com across something to keep it flashing while the screen comes on.
Anyways i don't like the led location, i never see it.

Agree Stupid place to put it, but at least it has one unlike LG & Samsung phones. hope it is possible to stop the phone from waking by pressing the home key though.

I want programmable notification lights like the X1 had.
My X1 still works, but it lacks any decent software to make it work well.

I love it! I ordered a PDAir case with a cutout for the light so I can see it witout taking it out of the case.

Anyone tried Light Flow app?
I hope we can use the lights of the buttons under the screen as notifications too

Would be very nice to have the option for the 2 lights in between the 3 front buttons to flash with notifications aswell.

This was exactly what i was thinking of, it would be great.

That would be BackLight Notification (BLN) it exists for samsung phones that doesn't have a LED.
But it needs a modified kernel to work. So we have to wait for SE to unlock the bootloader and someone to adapt the kernel for bln to work.

It's possible in a cyannogen mod rom under led setting... we'll have to wait for custom roms to use it that way..

At 3:00 Minutes.

has anyone found a way to make the 2 LED lights work for notifications?

Any news on this topic? Will it be possible without rooting the device?
Would be perfect if I can use the front-leds of the device for notifications.

Control the LED notification light!

[APP][ROOT][1.6-4.0] ButtonLED​
EDIT: I figured out that we can actually control the LED notification light with this app now. Instead of using the file for the capacitive buttons, just substitute it for one of the LED files.
Green - /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/led:green/brightness
Red - /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/led:red/brightness
Remember to also enable it in Accessibility! It still doesn't work well for any time less than 1 second, but I don't feel like that's a huge deal.
If you want to use the button LED, you can still use that file as well.
Since the OG's notification light (or frequency) is shameful to say the least, I just discovered this app today and it's sooooo handy for our phones even though it was meant for phones with no LED at all. Basically, it uses the capacitive buttons as a notification light.
Download the HDPI version and install it.
When you first open it, you have to tell it where the button backlight file is since it's different on every phone. Ours is located at /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/button-backlight/brightness.
Lastly, scroll down in the main menu to where it says "Enable ButtonLED in accessibility" and click on it. It'll take you to the system accessibility settings where you just have to toggle it on.
It took me a little while of playing with the settings to get it working how I wanted, and you can do the same. I have noticed a few issues here and there, but overall it works pretty great. One thing I found was that if you try to set the LED on time to anything less than 1 second, it just does a real quick flash, regardless of what length you chose. Personally, I like 1 second on, 1 second off.

Thanks for posting. :good:
Have you noticed any change in battery life? Reading the developer's posts, when the notification lights are active the phone doesn't sleep.

No difference so far, but I don't think that I've had a notification that I haven't seen and cleared within five minutes. I'd be interested to see what the drain is if it goes unmonitored for a couple of hours.

I can't even get this app to let me change where the led is located. How did you get it to work?
Edit: never mind I simply had to update my busy box version
BTW: I love you for finding this app

LOL, nevermind, nice find!

Hey thanks I've been looking for this, but if you've tried cm10 the led notification is kinda amber greenish, i wanted to know if i can get that same color, is it possible?

Not with this app unfortunately. You can either tell it to use the green color or the "red" (orange) color for the LED and that's it.

Works on stock kernel?
Is this supposed to work with stock ZVC kernel?
Test works, and the logs show that ButtonLED detects and processes my notifications, but it won't light the led.
I tried everything, what he says here too:

But terminal gave me an error creating the path.
does that means it's not supported?

It's time we start looking into the Heart Rate Sensor Light as LED Notification

Painfully, Samsung have removed the notification LED hardware, a $0.20 savings for the company. Now it's time we should look into the Heart Rate Sensor's LED lights as notification LED. At least, we will get something on device, though on the back.
I believe it may be possible if we can acces to the SDK. Only two things, if we can pulse that LED alone and how much powet utilization may happen. Lets see if someone can find this up. I will also start looking at the Samsung HRS SDK. I know we have more skilled devs. Lets figure it out guys.

You can already use the camera hole punch...
https://play.google.com/store/apps/details?id=com.used.aoe

I agree with you. I know that Always on Edge is available for Notch notification. But with this on, we risk AMOLED burn-in. Also, this is not a hardware. Since the heart rate sensor have an LED, I think that will also be useful for a lot of us. Lets see if we can figure something out. Also, we will have the option to use, whichever is more helpful for us.

I read somewhere in the forum, that Samsung is working on using the camera hole punch as LED notification, similar to how it behaves when you switch to front camera, also it was written by a Samsung Ambassador on the Samsung Forums.

I also wish that Samsung does something like this. But I don't have so much faith on Samsung's software update timeframe

If you want something on the back, just use the flash.

TBF Turning your phone on risks burn in. Having on screen buttons risks burn in. Using your phone outside risks burn in. Just live a little and don't worry about something like that as much. Just my opinion.

There's an option (when you check "when a notification comes" and "and screen is off" or "always") to show it 8 second every 30 second.
BTW, it's not really reliable this app, sometime works, sometime not. Let's hope samsung will implement a similar system setting.

Never worked for me as well (S10+) ... I tried every setting, nope, the way it works is, if you wake the screen, then it works! but that is pointless ! the whole point of notification is for u to be able to see u got it without touching ur phone!
I cant believe Samsung thought they can take this out!

led notifications?
Maybe it's time to move to 2000's.... who cares THE led notifications, when you have AOD!!!!

We like strobe lights from a distance

In the latest ASCA update, the blue light in the heart rate sensor blinks when power sharing is enabled. So, there are plenty of chances we could enable the same. Although I am pretty much ok with the current AOE implementation.

[APP] NotifyBuddy - Notification light when screen is off

Just download it on the Playstore NotifyBuddy. The app developer XanderApps made an amazing simple app to bring back a simple and beautiful notification light when the screen is off. Easy to configure, allow all the permissions, pick the apps you want it to show the light for, choose a color, and that's it. You can tinker with the settings for the duration of the blink, how long it takes to blink again, and how long it blinks for, which is a big one for me because other apps do not let it go for very long from what I've seen. The developer also said that there is screen in burn protection built-in! The only thing is AOD settings get disabled when there is a notification as well as screen-off fingerprint unlock and a double tap of the screen is needed to wake the phone up, or alternatively press the power button.
No notification light is an issue I had found with the note 10 + coming from the Note 8 and this is resolved for the most part
Lemmi know what you guys think about it !

Does it work with AoD?

When a notification arrives, does the fingerprint scanner works?

And from yesterday (or i have not noticed it earlier) when the display goes dark, it shows a message that no pictures are selected (however i have no picture-style aod choosen)

Only works if i press the power button on my s10+ any ideas why?

Haven't logged in in awhile but it can be used with or without edge lighting. I just tested with a 15 second delay (found in the notify buddy settings) and it works.
Have a nice day !

I like the idea of it but I don't like that it doesn't work as well there like when I plug in the charger it doesn't allow the display to turn off until I manually do it

Hmmm, I just tried on my Note10 plus. Plugged in charger, screen timed out at the 30 seconds I have it set to time out, charging led was present.

Fingerprint unlock doesn't seem to work unless you tap the screen to wake and then fingerprint unlock. Also the position seems to change slightly every time the notification blinks. I was putting it around the camera hole and the first blink is perfect around the camera but then the others are off to either side with each blink. Once these are fixed and I make sure there's no battery drain, I would probably buy the premium version.

How notifications work without LED?

Hi
I'm currently with a phone that has an LED notification light which is pretty convenient for me because I'm the type of persons who usually check his phone only when there's a message. Nowadays, I knew that this convenient notification LED have been discontinued
If I buy a future One Plus phone, How can I tell if I get e.g. a whatsapp message without constantly checking my phone from time to time?
P.S. I'm also not interested to have an that thing called "on screen display" that is running 24/7 just for an average 2-3 messages I recieve / day. I'm aware of software notification LED in the app store but I'm not really into software solutions because they tend to eat battery life pretty much the same way as on screen display.
I also don't really understand what's the deal about eliminating it?! if they can't find a space for it on the edges - because edges became so small nowadays - they can simply merge it somehow with the punch out lens for the front camera! or make a built-in software solution that popus out the notification on the screen ONLY when I get a message.

First I thought that same but I think ambient display replaced the notification led. If you lift it up or just tap (not double tap) on the screen, you will see your notifications. I don't like always on display too.

No, if you get a message your phone will turn the ambient display on too, to show you the notification. But after a few seconds it will turn the screen off again.

That's still not convenient because I may not be present beside my phone to see the notification when it's triggered. The notification LED is blinking in a nicer continuous way to tell me that there's something i need to check. I still insist that ditching it was a very silly decision towards inconvenience

It's not good as the app needs to be running all the time even in the background to deliver notifications. I read so many negative reviews about such apps. Nothing is convenient like the LED notification

When using NotifyBuddy, disable notifications on ambient display and double tap to wake, so it can work properly.

The whole point of the discussion is return of the notification LED which doesn't need constant unlocking for the phone to see if there's anything new, nor does it need an always on screen display

I find the lack of LED very annoying.
yes, you can tap the screen, or lift it up to check, but I find it very common that a notification icon is NOT present, but if I unlock, and scroll down, I will see a new email/text/etc.

AOD, if well done, does not drain any more battery than a notification LED. When you get a notification, it will only lit up a few pixels on the screen, in any shape you want. You can literally simulate a LED with AOD. Personally I use the app "always on edge", I set it up to show the name of the contact and the messaging app when I receive a text, super useful, way better than just a LED. I didn't notice any more drain in battery life, I can still very easily last a whole day of heavy use.

that looks interesting.. thanks for the tip.
EDIT: I can't get AOE to show up on my OP7T when the screen is off? Am I missing something obvious? I gave it all of the permissions I saw it asking for... but still no visual way to tell I had a notification without touching the phone.
