Is my led working?

Hi all, I've just missed called my gn phone to check how the led notifications are working, I see no led notification at all, no led lights anywhere on the phone to let me know I have a missed call? Is there something I need to set up, thanks

Check your notification settings

There is also an option "pulse notification light" in Display settings.

i have the same problem.
i have ticked the option "pulse notification light" in Display settings but th eLED doesnt flash after receiving a miscall. i waited a few mins and still nothing.
i know the LED works because it flashes while the caller is calling, but just switches off after the caller hangs up.
is there another notification setting for this other than the one in Display Settings?

The notification LED has been implemented pretty badly natively. In addition to not appearing very consistently it also only flashes white. Look for the app Light Flow on the market and use that instead.

Thanks Chrono.
I just saw the Light Flow app recommended on the other LED notifications thread and tried it, and it works well!
But yes i agree its seems a pretty sloppy implementation by default, i hope it gets fixed in a software update, although i probably wont be moving away from light flow with all the extra control you get with it

Customize led notification?

I want to be able to change how fast the led blinks bc every time I look at it I have to stare at it for at least 30+ seconds to see if I have a message. Thx

If you're rooted you can use the app called light flow. It allows you to change the color of each notification light and the frequency it blinks at

Light Flow
You can use the Light Flow app to manage your notifications. You can alter the light speed (slow to always on), and light color, along with vibrations.
It's nice to be able to know whether or not you got an e-mail or a text, with only the vibrations in your pocket.
Check the market, comes in a "Lite" (free) version and a $1.99 full version (more apps supported).
Root is not required. I've been using it on my nexus since the day I got it.

Careful with Light Flow, When I installed it and set it up, whenever my phone went to sleep mode the program wouldn't allow my phone to wake up again. I summarily uninstalled it and got a refund.

An update from the developer takes care of this issue. The app works as advertised, quite well too.

I also recommend Light Flow, it has worked flawlessly for me. I really like how it allows you to choose whether you want the LED to rotate through all your notifications, show the most recent, or show the highest priority.

You don't even need to be rooted to use light flow!

is it possible to add WhatsApp to lightflow?
(I see its supported in "additional apps supported by light flow", but the device only detects Google Talk in social apps)

Yes, default colour green.

Go with Lightflow. Another nice feature for us crackflashers is, Lightflow will let backup your settings/preferences so once you set up a new rom and install the app it takes 2 seconds to restore your settings.

Recently whenever I enable lightflow in accessibility my phone gets all ****ed up and I can only do something if I use 2 fingers

LED continues to flash on sleep mode, Light Flow installed?

I have light flow, and when my screen shuts off, the LED light keeps blinking (white.) Any idea how to make this stop?

Well... my solution was to uninstall it.
Basically I found that while Light Flow was pretty neat, I was getting quite a few random notifications (i.e. LED flashing but no notifications in the bar) that would only stop after rebooting.
Eventually I got fed up with it and removed the app. Shame.

Hey, I would try clearing the apps data or a reinstall to see if that fixes it. I am using it the past two months and never had an issue. Good luck.

Check your lightflow notification settings and see which notification is set to flash white. If it's SMS or email, make sure that you don't just clear the notifications by just swiping it off the drop down menu but actually go into the apps and mark them as read. Otherwise lightflow will still detect them as unread and notify you.
If none of the notifications are set to flash white then you might have not set lightflow up properly. Go to your accessibility settings and make sure that lightflow is enabled. If that doesn't fix it uninstall and reinstall the app.

Never had any issues with Light Flow, but don't use sleep mode as an LED blinking when on charge isn't going to wake me up (AudioGuru mutes sound on sleep profile, mind)
Ultimately if you're having issues get in touch with the developer as only they can fix the issue

Disable the notifications for anything that is set to use the White color. It should solve the problem. You most likely have the notification set to only clear when you enter the application. I personally prefer to clear it when my screen turns on because if my screen has turned on, then I have already "checked" the notification and don't need that light continuously flashing.

Phantom notifications has long been an android problem. Its not light flow specific

LED notification

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.

Light flow makes led after sms stay on

Even after clearing the text message, light flow keeps the led on after I turn the screen off. I've seen this on other types of notifications as well. Anyone else have this issue? I'm using the latest light flow.

Have the same problem. Uninstalled until they get the accessibility settings fixed. Waiting on samsung...
