Notification light? - Nexus 10 Q&A, Help & Troubleshooting

Is the LED below the screen supposed to function as a notification light? I ask because I haven't seen it light up even once for anything. Not when charging, nor when there are new emails, messages, etc. Heck, does it work at all?

I see the notification light blink white when I have a new email from Gmail. Do you have Settings->Display->Pulse notification light enabled?
I guess you should make sure you have email notifications (do you hear sounds?) on as well.

I to have yet to see this notification light. I do have Pulse notifications enabled and yet nothing happens when charging even after the device is turned off and charging. I'm unlocked, rooted, stock, with CWM recovery.
Edit: I also do hear the notifications when receiving emails just not the light notification.

Yes, my pulse notification setting is on. I get the audible tone that I have email but no light ever.

You guys are not alone. There is another thread on this issue. Seems that the LED, for some of us, works sometimes but often does not work at all. There is an app called LED tester (free) that you can use to see what the situation is with your LED. Note that installing Light Flow is not a solution - when the LEDs are not working they will not be working under Light Flow control. So far I haven't been able to spot what triggers the LEDs to start or to stop working. Restarts seems to have no effect. With mine, when they work they work for a day or two then abruptly stop and stay stopped for a day or so.
A number of people seem to be affected by this but there is no indication yet whether this is a software bug (hopefully) or a dodgy hardware batch.

Mines been working since day one... Installed light flow and kept on moving

I've never seen the LED on mine, LED tester does nada! I'm hoping it's software but ultimately not too concerned, not a feature I care too much about.

Where is the light supposed to show up?

My notification light works, alas on both the N10 and the GN it *never* blinks on the first notification it should report after a reboot. From the 2nd time onwards it works as intended.

Didn't even realize this had an led...so guess mines never lit up either

The notification light only blinks when the screen is off and a notification is received...

By default, the notification lights only show up when the screen is off... and the moment you power on and reach your lockscreen, they go off... in my custom ROM, I have an option to enabled the notifications lights when the screen is on as well...

No kidding, I had to go look in the little book to see where the led even was!

I disabled it due to constant pulsing...mine works TOO good.

Looks like mine doesn't work. Even after using light works app. This may push me to exchange this now along with light bleed problem that is pretty visible.

LED Color notifications

Is anyone running an app on their slide for changing the led colors when messages,calls, etc comes in( for non-rooted phones) or do you need root for this?

I have tried many; all have been a epic failure showing only a green light no matter the color selected... And I'm not running root, not yet anyway...
Wonder if it has to be something like the trackball for nexus (trackball alert free) ill test that tomorrow and post back if it works

After looking at the LED real close while it was charging I noticed the orange is at the top of the spot and the green is at the bottom. If you look real close while it is lit up you'll notice there 2 LEDs on the chip, so it looks like orange and green are all we'll be able to get

LED light to blink more often?

Is there any way to get the LED light to blink more often? Like on galaxy s3 it blinks every 3 seconds..
(I guess Light flow could, any other option?)
EDIT: see post #6
Light flow in the Play Store
There has to be a way without an app. If that app can do it on stock odex roms, I'm sure it can be done. People are having slight issues with that app.. So I decided to back off from it

Completely stock, no. Custom ROM or an app that enables it, yes.

People having issues must be user error. It generally works perfectly for me. Every now and then the LED doesn't blink when it should for some reason, but even that is rare and no big deal. Light flow is infinitely superior to stock.

For anyone on CM10.1 go to setting/system/notification light and change Default to normal and normal.
It will then blink every like 2 secs.
Yeah, light flow is really the way to go. Which reminds me, I need to buy the pro version...

Mine is working but for some reason I can't use the default "messages" notification. I have to use the specific one for handcent. It was also causing some issues with my gallery and stock browser.

I didn't realize people are still using this after SIII since we DO have an LED notification light and apps like Light Flow and Light Manager to control them now.... any reason I'm not understanding? Feeling nostalgic or are more of a visual learner preferring to see the icon instead of a flashing light?

For me I like the larger, brighter, moving icon that catches my attention faster than a single LED. To each their own though.

Of course, just wondering! Thanks for your insight :good:
Can you look at the led light and tell whether an incoming message is Gmail or a text? NoLed has icon notification that lets you know what is coming vs just a blinking light.

I can tell the difference. I use Handcent SMS and it allows for custom LED notifcations, also a few roms had custom led color features.

If you had searched for Light Flow or Light Manager, you'd know that those apps are designed specifically to change the notification lights to tell you what app is has a notification.... So.... Yeah, there's that.... Hmmm

It has a Pulse Notification Light!

You have to enable it under display settings, but it does exist! Sorry if this is common knowledge.
Was enabled by default on mine
I thought a feature of 4.3 was a notification on the screen that would pulse? I would honestly rather have that feature.

That appears to be a Motorola-specific feature, not baked into 4.3. Granted I would not be surprised to see that feature become standard in a future version, but it isn't right now. From a user front-end perspective 4.3 changes almost nothing.
sucks though it's only white. can'tdo other colors with light flow

Is it white because it's only white, or is it white because LightFlow hasn't been configured for the RGB LED yet? I think (and hope) it's the latter.
not sure.. hoping for the same!

How can I test this?
Mine was 'enabled' via display settings, but it doesn't seem to be working. I've received email notifications, but I don't see any indicator lights. Am I missing something?

From playing around with it, it seems it only pulses when the screen is off. If you get an email notification and your screen turns on, it won't show. Try waiting until the screen dims after. It should be near the base where the charging port is. I almost missed it since it's so low!

Try this app to see if your light works or not. Mine works, but only white

Thanks. I was able to force it on with the app, so I finally see where it is located and can verify it works.
I have to say, I'm not to impressed with it. It's so dim that I don't think I would notice it unless looking for it. The notification light on my phone is about 100x brighter.
Mine seems to be broken. I tried this app and turned off the screen and I still see nothing.
It also has speakers. Test them in poweramp music player with high volume.
I didn't have to enable it either.

Does the N3 have an led notification light?

Anyone know?
As the N2 does not.

I would imagine that the N3 has an LED notification light. But the N2 also has an LED notification light. It is just left of the top speaker grille, above the Samsung logo.
Great thanks. If the N2 has one then the N3 should have one two.

Multi-color please
My fingers are crossed the notification LED is multi-color (and more than just red/green/yellow) so you can quickly identify the type of notification without relying on a blink pattern.

I have the S3 and never really noticed a "blinking pattern"...
Mine just blinks (blue and green and red). On / off / on etc.
Tell me more about this pattern?
There are 2 dots next to the speaker grill, so there should be a LED notification light.
As to multi colour led lights, you can always use apps that make multi led colours! I have atm purple, blue, red, orange, yellow and green for my notifications.

Some phones use a pattern to differentiate different alerts (text, email, voice mail, etc.) and there are apps that let you control this too as there are apps that let you assign different colors.

This only works if the LED supports those colors, some LEDs are only 1, 2 or 3 colors like the HTC EVOs. They use a pattern instead of color, otherwise red for charge, green when charged or blinking green for notification and yellow for low battery.
I just hope the GN3 notification LED supports multiple colors. Is the notification on other Galaxy phones multi-color?
I would assume the Note 3 would have something similar to the Note 2. I have red when charging, green when fully charged, blinking blue for most notifications, blinking green for a text message. Don't see why they would get rid of that.

If you have N2 and don't see LED notification light, then you probably won't see it on N3 either, because evidently you don't get anything to be notified about...
N2 has 3-color LED and these colors can be combined producing different colors (require additional apps or even kernel)
Don't worry guys, I'm sure the led is cheap enough for Samsung to keep in the GN3.
This video will answer all of you the questioning regarding the led notification:

NB: GN3 is the one on the RIGHT!

If anyone is still in doubt the Note 3 I had this weekend has a notification LED. I don't think Samsung has time to remove it in the next week or so.
