LED Notification flash - Not working?

I haven't fully tested this issue yet mainly because I've only had the phone for a few days... I wanted to check if anyone else had this problem.
Under Settings -> Sound & Display -> Notification Flash
I have all the options ticked.
In theory, whenever I have a missed call or a SMS or email etc, I should be able to tell that I need to check my phone be a little blinking light in the top right corner off the screen. I just came back to my phone and this LED wasn't blinking but when I turned on the phone, there was a missed call and a SMS.
Other times, it seemed to work fine.
Anyone else noticed this problem?

it only flashes for 5 mins and then stops. There is no way to change this without additional apps.

Oh... How disappointing. Pretty useless imo. Thanks for the info. I wonder if they will fix it. My previous phone, Touch Diamond, had something similar but it never stopped flashing until you looked at your missed calls.

Now that explains things. I tend to look for the led after I've not used the phone for a while. In my pocket or elsewhere. Quite a few times I've seen no flashing but have a notification in the top left. I thought it was another one of those little 'features' we keep finding.

Yeh i discovered this awhile back and it's annoying as hell, i just use a app called Missed Reminder which can be configured to allowed it to keep flashing indefinitely

I was just going to make a post about this. I thought the LED notification wasn't working at all on my Desire, since I've never seen it, but perhaps it had just stopped before I had the chance to catch it, then

What apps are you referring to? It would be nice to be able to have the LED flash longer.

I'm guessing this is to save battery time, I don't know how much power a small LED uses but it surely can't help with the already abysmal battery life

I first thought the LED was located behind the optical trackpad, because the trackball on my Hero could light up. I think the LED-notification is pretty dumb since it's almost invisible when it lights up. The lighting trackball was much much better

This is a known issue. I thought that did not happen in Android, but I guess I was wrong.
If the phone work in Windows Mobile, there are a registry key to let assign values to the options, so they are usable.

In Android, I have no clue... maybe my info help in any way.
PMoto

It would be nice to be able to change the flash time from the default 5 minutes, or atleast an option for no time limit.
I know it's to help save battery life, but I'm willing to say that the light flashing will use less battery then the back light coming on everytime I'm away from my phone for more then 5 minutes, from me checking to see if I have new messages, email, or missed phone calls.

Same issue with my recently purchased A40.
No blinking at all despite screen flash notification selected.
Hope someone can help

LED-notification

Hi,
I noticed that the LED-notification of my silver Desire doesn't work when I receive/missed a phone call, email or sms... I remember that the LED started to blink on my old Hero when I received or missed a call, sms or email.
Someone at work received his Desire too today and I tested his LED notification and it doesn't work neither, now I'm wondering whether all Desire's have got that problem or is it normal that it doesn't light up? Maybe it's an issue of ALL desire's?
I need to know it asap because I have to go back to the shop if it's actually broken. I can get a replacement...

Mine works so far

mine works but seems to give up after a short while, which is useless tbh....
JAmes.

Yeah mine works, but I did read in another thread that the notification turns off after about five minutes...making it kinda pointless

Same thing happends on Legend too !

the led is the small thing on top.
Not the big thing in the bottom.
There have been other people that made this mistake, so i'm just making sure

??? My desire only has one led if you don't count the buttons.
The hero has a trackball, with a led. The optical sensor in the desire doesn't have a led.
The led on the hero also stopped blinking after a minute or 5, very strange design...

Yep. It seems 5 minutes is all we get... I'm sure its a fairly simple fix though?

the 5 minute notification LED is plain SUPID !
is there an app/widget for this ?! a LED-notification-keep alive or something ?

Use handcent for sms, and touchdown for emails. You can also try missed calls

I'm using MissedCalls, both for SMS and Lost Call.
@pina_:
verify that (translated from italian menù...)
menù/setup/tone and display/blink notify has all the mark checked !

I couldn't find "handcent" on the Market ...
But Missed Calls kicks asss, just what the typical Legend/Desire needs.
thanks fblasot!
Later edit: yeah .. Missed Calls does not work on my 2.1 Desire.. The notification LED still shuts down after 5 minutes ... Bummer

oh,
I was convinced that led was working well...
Yeasterday I tried with a lost call and after 5 minutes led stops blinking
But the option "repeat sound & vibration" after N minutes work, so at least some sort of notification is still available with missed call.
I read on the missed call application note that led notification is a problem of android 2.1...
Today I tried with an sms and led blinks for 10 minutes (with each 5 minutes sound and vibration still available...).

Sorry to drag up an old topic but I have a minor problem and didn't really want to start a new one for it.
When my Desire is charging is shows an orange LED to show that it isn't finished and a green one when it is. Lovely. Problem is, if I receive a text while it's charging, it then starts flashing blue to show me I have a message but after I have read or replied to it, the charging LED won't come back on. The phone is still charging but it doesn't light up.
Is this a common thing? I'm using Handcent by the way.

LED notification is not blinking correctly and works sporadically

Ive tried several roms and all seem to do the same thing. It may have even done it on the stock rom but I dont remember.
My LED notification when I get txts or emails is not blinking correctly. It will blink very irregularly for the first 15 seconds and then sometimes wont blink at all after that. Ive tried custom apps like go sms and an app that forces the light to come on at fixed intervals but it still wont work right, like something is conflicting with the light coming on.
Has anyone else experienced this or know a fix?

Im on the latest Frankenstein rom, but Ive tried the latest Bonsai one before this and it did it as well.
Theres others experiencing this as well but I havent found any fixes for it yet, even the apps they recommend dont work for me.

Try Missed Reminder
My configuration:
Start/Stop Service (Check)
Autostart (Check)
Everything else disabled.
Preferences settings for Missed SMS/MMS/Missed Calls/Missed Gmails
Turn the screen on (Unchecked)
Popup (Unchecked)
Vibrate (Unchecked)
Ringtone (Silent)
Blink Led (Unchecked)
Notification Intervals (1s)
Number of repeats (Forever)
I found that by using these settings, it forces the device to keep the LED blinking. I also found that you can then use apps with custom LED settings like Go SMS to change the color and LED blink rate with no problems.

Its always done this. Maybe one day we can get a fix. Sometimes mine works just fine and other times it is very sporadic.

Same here. Always done this from day one. I had a brand new Epic, played around with it, and the LED crap never worked. On that particular phone, the PRL would never update so I took the phone back and got another one. PRL worked fine, and the LED on that phone did the same thing.
I also have the LED to set to keep blinking in Chomp SMS, and it does not work. I have ALWAYS gotten the sporadic LED blinks when I get a message, and then it disappears.
This has happened on the STOCK phone out of the box, as well as with DK28 and Bonsai 2.0.1.
So regardless of the ROM you use, you're still going to be out of luck. Until Samsung can get this fixed...hopefully in the new Froyo build coming out next week, then you are stuck, just like many other people are.
I have not tried that program that was posted by Isira, but you may give it a try and see if that fixes your problem. I tried a program similar way in the beginning and it didn't work.
It's worth a shot though. But Samsung knows its a problem, and that's all there is to it. You're stuck with it, just like me.
UPDATE I just tried the program and so far it seems to work. My SMS is still blinking. Not quite a true second like it is set, but it is blinking. I'll keep testing it, but you may give it a try.

I did try the missed reminder app and messed around with the settings but it still blinked sporadically. On a side note I used the samsung tool to update to EB13 and stock 2.2 and the blinking seems back to normal...

Notification LED doesn't flash

The new message notification LED on my (new) LTE Gnex only flashes once or twice, just when the phone boots up. Doesn't flash when a new message arrives. I've tried disabling it, and re-enabling it in settings, but it just does not work. This does not seem normal, and I'm wondering if I need to return the phone, which I really don't want to do. I've already unlocked the bootloader and rooted, but still running the stock ROM.

Have you tried Light Flow from the Market?
This has worked with the stock ROM.
I personally use Trackball Alert Pro - MoDaCo ROM has suppport for this.

Just tried calling myself, and hung up. The LED isn't lighting up. But I have seen it blink for emails at least. Hmm.. maybe try light flow.

Have not tried any 3rd party apps, yet. First I wanted to know if there was a problem with my phone, or if this is "just" a bug. If others have this same problem, then I'll try a 3rd party solution. Thanks for the feedback.

Tried the same thing, called myself and sent messages with no led notification. Thought my led was broken but then installed light flow and it worked no problems.
Not sure how it was supposed to work stock but could not get it to work at all without a 3rd party app.
Without the app, the only option I could fight was pulse notifications which I tried turning on and rebooting but it never seemed to work.

Just tried light flow. When I tried the "test LED" function, my phone would no wake from sleep. Also got sleep of death when I got an email. Had to do a battery pull. Any solution for this?
I looked at Trackball Alert and it requires Paul's ROM, which I'm not ready to try (yet).

I noticed it doesn't light up when it's charging either. Is this normal behavior?

From what I've seen so far the stock light is a hit and miss for me. Only time will tell how they will improve this.

Do you have it set on? Lol that's all I can think of. Mine works fine

Well its not your phone....The light stock is stupid I have no idea why you would include a light that only flashes random times and only in white..... I had issues with lightflow crashing my phone when waking with several notifications flashing. Just bite the bullet an flash ARHD or Paul's rom they both support Trackball notification and it works very well!!

Yep. Probably don't have/use most apps that support it for me to notice it all the time.

I've been having the same trouble. Haven't seen the light in days.
I went back and revisited some of my settings. I had turned on the setting for the screen to "stay awake while charging." I unchecked it, and now my light is working again.
Now, it only ever comes on when the screen is off to begin with. It won't come on if the notification happens while it's already on.
But at least the light comes on when the screen is off now!
(And I really wish the blink rate was higher. You can look at it for several seconds between blinks, and think there's nothing and look away.)

So the change I made to the settings seems to have fixed the light issue. I have been properly getting notifications since I turned off the keep awake. Seems like an easy enough to fix bug as long as they know about it.
But now what I want is a faster blink rate. One second on out of every 6 or 7 seconds is easy to miss.

[Q] Notification LED Constant Blue

This just started today. My notification light is a constant blue. It won't go off. I have no notifications of any kind. In fact I turned off everything. I'm not using Lightflow. I wiped cache and dalvik and even reflashed the Kernel (Franco). It's really eating the battery.
Any solutions? Most appreciative.

which rom?

thats the kernel lol. if youre on AOKP or CM9 check the led light settings
if its not that then it must be one of the apps in the background

Duh, sorry. I knew that. It's stock.
I can't find any running Apps that would enable an always on blue light. I've never seen this light except by modification. My green notification light is definitely not engaged at the moment as I've gotten numerous texts and emails that would have triggered it.
Any ideas at all?

have you got lightflow installed but disabled? if so you can check the accessibility settings to see if it is actually turned off,
other than that i cant see what could be causing a blue led. the GNex led by default is white for notifications. last resort would be to do a backup and factory reset

No Lightflow installed.
Damn!

install a battery monitoring application to see what exactly is eating your battery, that might show up with something

You said in the OP you weren't using it, not that it wasn't installed. If you're going to be rude, then fix the problem yourself.

Uh, wasn't rude. Just responding to his question. The damn was directed at my frustration.
Peace.

Did you just install handcent?That blinks my light blue for texts.

Facebook notifications blinks blue too

Facebook notifications are completely turned off.
Handcent has been installed forever. But I haven't made any changes to the notification process. And the light doesn't blink. When the screen is off it is constant on.
The light recently turned off. But as soon as I unlocked it and locked it again the light came back.
Weird....and sooo frustrating.

All of your LED notifications are disabled? In that case, enable them ALL! LOL, That's what I would do anyway. And try to receive as many notifications as possible. Worth a shot.

At this point, I would just wipe the phone and redo a clean install. You'll end up less frustrate than trial and error to find the fix.

Yeah, but I'm really trying to avoid this. My next step is a Nandroid restore.
Sigh....

Today I had the same on CM10, freshly installed (with wipe) yesterday. I shut off the screen and the blue LED goes on constantly.
Before that, I had this issue on Stock ROM. Really don't know what's going on there, some ppl in german forums are having the same issue.
A reboot or some tricks (send yourself a text message) do help clear the LED. My catlog says nothing, i.e. I didn't found any suspect message.
