The notification LED was a great improvement to the Galaxy Nexus over the Nexus S, however, the default settings in Android 4.0 blink the light very, very slowly, so slowly in fact that I often don't notice I have a message waiting even though the LED is blinking.
Is there any way to force the LED to blink faster? At about the rate that HTC notification LEDs blink?
Download Light Flow Lite, it is a Free app that lets you customize:
SMS, G-mail, E-mail, Charging, and more.
You can choose intervals of: very slow, slow, normal, fast, very fast. And how long you want it to blink.
Great app, and used it since Day 1.

AOKP has this feature as part of the ROM. It has flash on time and flash off time, from 0.5 to 10 seconds.

I need this too, can I have it without installing an app? I'd like something that I can flash directly.
Light flow is good, but it is a battery destroyer. Upwards of a hundred alarms and wakelocks over a 3 hour sleep period, and this is without receiving any notifications!

exactly, and the roms that have it built-in don't drain as much battery. thats why I need a better solution than lightflow
Here's more on LightFlow:
If you use LED color cycling it will destroy your battery because LightFLow needs to keep a thread alive.
<rant>
You can thank some stupid designer and/or use-case engineer at Google who clearly either doesn't use an android phone or is just plain clueless.
</rant>
The problem is that the phone never really goes into deep sleep when you are using color cycling because the wake-lock by a thread which needs to continuously change the colors keeps running and kills your battery.
Ideally, the way the notification module should have been designed is that an app should be able to specify a sequence and a blink rate to the LED chip, which should then handle LED lighting, independent of any future CPU intervention/dependence for minimal battery hit.
But since this is not the case: I have LightFlow setup with 'show latest/last color' on battery and fast cycling on charging only. This is a good balance with literally no perceptible impact to battery life. If you don't mind a little more battery drain then set priority-based notification colors on battery.

So, I sold my Nexus S and bought a Galaxy Nexus today. I cannot seem to figure out exactly how the LED works. It doesn't seem to work reliably for all notifications.
Can someone please explain how the LED system works and also if you can customize the colors per app/person
Light flow from the Market...
I second light flow. It gets hung up sometimes and still glows after I viewed the message or call. But stock notifications never worked right.

I like the setting for it to clear the led when you turn on the screen. I don't think it's ever hung up on me that way.

On stock there doesn't seem to be a way to adjust the notification light, without the aid of an external application. In saying this though, I haven't been able to work out the rate/times it blinks as sometimes it seems to double blink then sleep for a longer period then blink at a normal pace.
I only really have text messages come through with the odd call, so I couldn't verify the other notifications.

I wish stock was able to dosimple mods to led notification like colour and interval. I dont like tonnes of apps to run in the background all the time.

This is such an obvious improvement I would be astonished if it did not show up in one of the next ICS updates.

Yeah its the only way LightFlow can work without false positives it seems.
And the GNex has a ton of RAM. Having a 7mb app in cached background is am issue?! The RAM is on anyway, you might as well use it.
I think both stock notification and light flow are far from being perfect. Both failed on various occasions, the former more than the latter. Therefore, I think there is room for a new app to accurately control LED notifications on the Galaxy Nexus. I would pay even 10 - 15 euros for such an app.

Shame that setting isn't global
Using Light Flow Lite also. My tip is to just use it to manage the LED, don't use it to manage sounds/vibrates unless you feel like being really anal about your notifications. I found when setting it up that I got a lot of double notifies and crap that I didn't want. Just my 2c.
I installed the apk NoLed from GooglePlay (https://play.google.com/store/apps/...lt#?t=W251bGwsMSwxLDEsImNvbS5sZWQubm90aWZ5Il0.) and i think it is a fantastic apk as we don´t have a regular notification led as others phones.
How does this work exactly does it prevent your phone from going to sleep? What about the Lock screen? Do you have to remove the lock screen to see this?

You have lots of options to configure the apk, when i receive email (gmail) my phone vibrate, make a sound and the screen blinks an small mail icon, all black, just the icon. You can set how long it will blink, can also ajust the proximity sensor to not show the icon when the phone is in you pocket, and so on.
Too much to tell, install and try.
Seems good!
Thanks
The app is quite good, very customizable, but it drains too much battery. Energy saving options are not enough.
Sadly uninstalled.

Are you referring to with even no notifications active? Or with notifications active?
For me, it doesn't seem to bad, though overall batter drain is like 10% over 10 hours, sleeping with nothing else active.
Can't say.. if i get a text, or just a whatsapp notification or anything else, my battery is drained when i take it back. I don't say that battery is halved, but it is still a remarkable loss.
This is why we need BLN. BLN should use a lot less juice as it is only a small LED and not a big screen. Hopefully someone will modify the ICS kernel and we will get it.

From what you said, i'm assuming you totally has no idea how (AM)OLED screens works, so let me give you a fast walktrough.
On most mobile phones you can see TFT-LCD based screens. These screens uses a background (white) light trough the entire screen surface, this light is first polarized then secondly filtered. This filter is controlled by the electronic, witch results how it blocks or let's trough the way of the background light, resulting the picture what you see on the screen.
However the LED screens, including OLED and AMOLED screen are rather different from the above.
Each pixel on the screen is one tiny independent light source, aka. a Light Emitting Diode.
When the question comes to power consumption, from the above you can see that the TFT-LCD has a relative constant power consumption, because the backlight always has to be on, even if the entire screen shows black.
As for LED displays, only those areas uses power, witch actually emits light, in other words: the pixel/screen area is else then full black.
This is the reason why "use as much black as possible" is mostly suggested for this kind of screen, because if the less leds emitting light, the less the power consumption are.
for further informations please read:
hxxp://en.wikipedia.org/wiki/TFT-LCD
hxxp://en.wikipedia.org/wiki/LED_display
hxxp://en.wikipedia.org/wiki/AMOLED
this is a must have... if u don't have an led and amoled and from what iv'e seen it isnt a battery hog...
I've tried the BLN app, and it didn't work for me. Has anyone gotten it to work on the glide?

I think the BLN pro app would be able to achieve the blinking. You have to buy it though.

Hey guys,
Ever since ICS update, the charging LED completely overrides all notification LEDs.
I used to have k9mail LED color set to white which results in the LED blinking red whenever a new email arrives. This works perfectly fine if the phone is not being charged and this also worked before ICS but this no longer works.
Anyone else notice this with their E4GT?
Thanks
My notification light has never worked except while charging it glows red, blue when full then unplug and sometimes it stays red

Yeah this beg has been there since the early leaks, Samsung screwed us on that one and I guess Sprint never made it a priority to fix. This works in aokp though so I figure it also works in cm9 and other aosp roms.
I don't even use the leds they just blink and drain the battery. I have them disabled for everything including charging. You can't see it blink in your pocket so all its doing is wasting your battery as it blinks away unattended and it has notifications and vibration to alert you to an incoming message. No real point in having sound, vibration, an icon and a light for a notification. Plus ICS doesn't handle the LEDs properly and they keep the SoC from going into deepsleep causing excessive battery drain. You use less battery to click the screen on and look for an icon than you do with the LED blinking til you check it anyways.
We are legion, for we are many.

Hello.
Is there supposed to be a light for when the device is charged?
Mine shows no notification of either plugged in and charging, or when at 100%?
Cheers
you should see a lightning bold in the battery icon when charging
Yeah, cheers.
I was meaning with the screen off. All my other Android phones had a notification light when charging (ie red, then turned green once fully charged).

use this app
https://play.google.com/store/apps/details?id=com.rageconsulting.android.lightflowlite&hl=en
I had assumed there would at least be a sound considering the 3rd setting in my screen shot, but there's not.
As for light flow, I used it a lot on my N5, but I tried it on my 5X and there were some issues.
First, there's the persistent notification... It's the way LF uses to keep the app running in the foreground, but there's a LF notification always in the pull down AND that screws with ambient display. If you turn that setting off in LF, the app stops working within 20 minutes of the screen being off, defeating the purpose of having a light blinking to let you know it's charging.
Second, not so much LF's issue, but you can't make the LED light up certain colors like orange. Regardless of shade, it all comes out yellow.
I'm really surprised that Google didn't add something for a charging indication using the LED...
Yeah, cheers for that.
At least I know its not just my device.

try out LightFlow LED
One reason I loved the nexus 4 was because of the ability to control the RGB LED. I set it up so that different notifications changed the colour of the LED.
When I moved to the Nexus 5, as far as I remember, it wasn't possible to set the LED to be always on, this really bugged me. It could only do long pulses.
Does anybody know if this is possible on the Nexus 5X?
It's the same as the Nexus 5. You can change all the notifications to always on and have it cycle between different colours at whatever speed you want, but the light will still pulse off briefly each cycle.
I have mine on pretty much constant when charging (as said above it will remain constantly on and go off every now and again for a very brief second) pretty much solid in my eyes though
