Notification LED Playing up?

Morning,
Is anyone else finding their Notification LED for text messages (Possibly E-Mail's too) is flashing for 2-3 Minutes then stopping? Missed several texts now because of this and its annoying me that I have to keep unlocking my phone to check for texts.
Is there an option I have missed? Do I have a dodgy Phone? or is that just the way it is?
KYI

I think mine does this too, that's why I was asking for a Wake on Notification app. Can we change LED from green or orange via software?

'Missed call' for the Market lets you (IIRC) change LED colour Whether is is fully operational on Desire, I'm not sure. Don't think you need root access either.

It's only flashes for about 2-3 mins then goes off - if you've not noticed by then I assume it thinks it'll save power...

makes sense to me to be honest. for example if u miss a text on the iphone, it will only chime once more. i wouldnt want mine staying on.

I Suppose I just miss it for the G1 days. My Phone is on silent all day at work and the continious LED was a bonus for notifications. Surely an single LED doesn't draw that much power? Might have to give Missed call a try again.

nah the desire seems to use different code to light up the notification LED so none of the LED apps on the market work anymore. like LEDtester, the LED just flashes green and cant be changed. and handcent, it just flashes green and cant be changed.

have it on vibrate instead - or just check the screen every now and then...

I did post about this earlier but got zero replies so I wondered if it was only me.
Mine blinks for I think it's exactly 5mins. That's it. And I don't think it has anything to do with saving battery since that one blinkiing LED (mostly blinking when then screen is off) does not take much power at all.
I've emailed HTC to see what they say.

Although not ideal, handcent does allow you to set notification reminders.
I have mine set to re-vibrate 15 mins after receiving a text if I haven't checked it. You can change all the options, so have it chime, vibrate, wake scree, flash LED, all of above, one of above etc. at different intervals and a number of times - I find once vibrating only to be a sufficient reminder if it's in my pocket, however if on a desk would probably have the screen re-awaken.
Might help.

[Q]Light Flow - question thread

Hi..
I have set up Light flow for several applications,but, for instance, when i recieve sms , i get sound and vibrate both when screen is on and when screen is off, but i get notification light only when screen is off.. What to do folx.. I know it sounds a bit stupid, but i would like that notif light when screen is on also..
Thanks in advance

Nothing. The LED doesn't function when screen is on.

Thanks mate .
One more question tho - i have set up the mod for charging battery : notif light lights up and stays on all the time while battery is charging.. Can this do any harm to led light or phone itself (heating etc)? Or it is intended so it can stay on for long time ?

I had light flow on my galaxy nexus. Although the features are nice, i uninstalled because it seemed very broken. The led would stay on evwn after i checked notifications and so forth. Yeah it was cool, but just didnt see the risk of burning out my led.

For me it works like charm .. But only think i want to know is this :
Can led stay up for longer time ? Like, for example, the HTC Sensations led is staying up for all time while you are charging (by default), and it doesnt burn out. So is GN led designed to stay up for long time, or no ? (Im asking this because i want to know if i can charge the phone whole night and have led turned up)
Thanks again folx

Yes it can! Start LightFlow, choose notifications"then pick the app of your choice. There you can able and enable (amongst many other options) the duration of how long you wish the led to stay on for that particular app.

LED's have a life of many thousands, if not, tens of thousands of hours. It's unlikely that the notification LED will ever burn out while you own that phone... Unless you keep the phone for six or seven years and keep the led on almost all the time!

If your led burns out consider it akin to winning the lottery.

Thank you all. ! I really like multi colored led.. I liked it on n900 (back in the old days).. I like it again I simply like when im charging the phone to have my led on all the time
Thanks folx

Ive let mine to constantly show an orange light while i leave the phone on charge overnight and a green when it is charged. Led's wont die on you unless you keep your led on for like 6years straight, so nothing to worry about

Yeh I found the same thing, seemed really broken to me, was so annoying to get rid of notifications and then still have the led going off.

Guys just a quick question. I think this led is three colors right? Red, blue, and green and to get other colors it just mixes them right?
If you guys use colors other than those three I mentioned do you guys kind of obviously see that theres more then one color shining?
Like for purple it looks like purple on top and redish on bottom. Clearly like two colors.

Anyone? Just wanna know if its how others have it or just me??

Sure it does
I have Light Flow set up to show a solid yellow color while charging. When I plug in my phone, the LED blinks on then off. If I turn the screen off, the yellow light cones on like it should. If I then turn the screen on without unlocking the phone, the light remains.
Only after I unlock the phone does the LED not function.

I found that problem was because of the ROM I was on. Some ROMS would need me to launch the lightflow app to clear the notification, but I use CND and it works exactly like it is supposed to. I could flash AOKP and it would work how you describe.

Does it have any kind of effect on battery life? Seems like it would keep the phone awake.

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.

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!

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?

[Q] Light flow/LED problem

I just switched from a Nexus 4 to a HTC One M8 GPe. On the Nexus 4 I used Light flow very much with many colors and blink patterns to be able to identify what was happening without turning on the screen. Now when I have installed Light flow on my M8 it's only possible to choose from 4 colors or something and no blink patterns.
Is this possible to fix?
Great phone but this really bothers me...

Someone can correct me if I'm wrong, but I believe that it is due to the limitations of the LED on the M8 vs the N4. It's a different type of LED so there isn't an ability to tinker with it as much.
I miss that from my N4 too, but ultimately as soon as I saw/see a notification light I check the phone anyway.

I suspected this but before I got the M8 I didn't even realize that it would have anything else than the best LED. But yeah, 90% of the times It's just a message of some kind so I guess I'll survive. Still annoying though...

Not only is it not possible to fix because of the limitation of the LED that the other poster mentioned, but I'd be shocked if Light Flow gives you any color other than green and if it works consistently.
I had messed around with it some a couple of weeks ago, and gave up. I guess it's possible the Light Flow developer has tweaked it since then, but the version I was using was pretty useless on the M8. I don't fault the Light Flow developer though. I blame HTC on this one.

I was able to get green and amber to work. Some colors would just pick green or amber, others just wouldn't do anything.

Yeah, it seems to work pretty bad. Are there any other ways to control the LED like Light flow? Does it work better if you just let all the apps control it themselves? I guess not?

I was able to get green and amber to work.

Green, deep orange, magenta and cyan works for me, but green and cyan shows as green/yellow on the LED and deep orange and magenta shows as orange.

Messed around with the LED settings in Textra after I disabled Light flow and suddenly it actually started to blink. Great improvement!
Is it possible to get it to blink in Light flow too?
Edit: Yes, enable color mixing.

Maybe I was unclear. To get it to flash in light flow you just need to enable mix and choose flash under the right color. This is not specific for Textra, but Textra can flash the Led by itself, without Light flow.

I've really tried getting it to work, but needed to put it in Direct Mode to get the LED with permanent light when lit, instead of flashing.
But in this mode the LED is dimmed even though the settings are set to 100% brightness in lightflow.
To get the LED 100% brightness I needed to remove Direct Mode and accept that permanent light instead didn't work, and live with flashing LED. Hence, not very different control than the standard setup i the Sense rom.
Any clues?

Try direct mode, root mode and HTC alternative mode. All three at once.

With that Setting the led is always permanent on dimmed like 20% through mixer and also standard control.

Yes, I had the LED flashing green from Textra, without Lightflow. But the Textra reminder options are so limited, I'd really prefer to use Lightflow if I can get it working properly.

Then I dont know. Works perfect for me. Really bright too. Have you turned off LED notification in screen settings?

I've been fooling around with this a lot since hearing the news that it was working.
I think I've got it working pretty well to my satisfaction now. As I was messing with settings, some of which I may have inadvertently checked (like the Samsung always on setting) I saw a number of interesting behaviors.
One was that at one point my basic notification was, instead of just the green LED flashing, a combination of alternating green and amber colors. (I'm not sure what I did, so don't ask me to reproduce it.)
At some other point I had the LED staying on even with the screen on.
There were other issues, though, when those things were happening. So I kept monkeying with the settings, and I think while neither of those things are happening now, for the most part Lightflow is working acceptably well. I actually would like it if the LED --could-- be on while the screen is on.
Also unless I am mistaken, after an alert, if the screen is turned on but the alert is not cleared, when the screen is turned off, the LED will not come back on. Is this what you two are experiencing as well? I'm pretty sure with my last phone if the alert was not cleared, the LED would continue to flash.
Thanks.

When the LED is alternating between two colors (or more on other phones) it's probably two (or more) notifications and you've got the settings to loop through them all. Standard setting is to do this when you have the charger plugged in IIRC.
The LED is working with the screen on for me and I think it always has on the M8. On my Nexus 4 it turns off when I turn on the screen and the LED turns on again if I don't clear it and turn off the screen. Great if you don't want to read the message right now and still don't want to miss it later. Since the LED is always working wether or not the screen is on, this is not a problem on the M8.
But if it's possible to alternate with both colors on the same notification, that would be a great way to get a third "color". Could you check if it is like I said or if it really is dual color?
EDIT:
I got it to work! In mixer you can set one color to solid and one to flash to get both. So there are actually a difference on green + amber and amber + green. This will give us a total of 6 options: green, flashing green, orange, flashing orange, orange + flashing green, green + flashing orange.
EDIT2:
The non-flashing color isn't very strong, so I'm not sure how useful this really is.

It was definitely not really two notifications, though it is somehow possible that Lightflow was acting as if it were. The alternating was definitely like the alternating LED colors that I used to see on my last device when it was alternating between notifications.
I can't reproduce it because I don't know what crazy combination of settings I had at the time. The Samsung always on setting was probably involved. It's even possible I had incorrect checked the Samsung root mode. I was really trying lots of things, and not sure of what I was doing.
Right now, as you suggested, I have Direct Mode, Root Mode, and HTC Alternative driect mode all checked.
I have all LED notifications turned off in Settings/Display and Gestures/Notification Light.
I have Textra set to not notify me in any way, and am using LighFlow for notifications and repeat notifications.
I have not tested things much, so I really don't know how well it is working, but it basically seems to be, though I definitely do not have the LED staying lit with the phone on, or after I turn it on and then back off.
I wonder if some of the differences we are seeing could be due to versions of the phone, rooting procedures, etc. My phone is the Verizon version, and I used Weaksauce to gain root access. Could this make a difference?
Again, many thanks!

It is not possible to fix because of the limitation of the LED.

Notification LED

Hi guys, could you please confirm if the a2 lite has a notification led and if so is it multi colour configurable?

Yes. A singular color on the left bottom.

may as well class it as useless even when charging it still is white only

Maybe you can find some Xposed Module for custom LED...

That is sad my older phones at least have yellow red and green
It is even configurable via third party apps or like I am using custom roms
Any way it doesn't bother me if its blinking smoothly or at least just blink it not a sloppy 3 step transition

Have a look at the Light Flow app. Unfortunately changing the blinking speed doesn't work but at least it's possible to define the apps whose notifications are switching the LED on.

Sorry it seems there is much confusion around about the (white only) notification led. I'm still reading people stating that the led just lights up for showing that phone is charging, and do NOT lights up for notifications like missed calls, pending incoming messages and other usaual android notifications.
May you please confirm that indeed it DO lights up for android notifications and not only when charging? Thanks
One more thing: if it lights for notificatins but it also lights pemanently while charging, how do you distinguish notifications while charging?

It blinks for notifications and is permanently on while charging. Not sure what happens with notifications while charging as I only do it over night every 2-3 days. Never had any problems with the LED by the way.

Thanks rfkf you cleared it up!

If any wonders exactly.
Made some test.
White led only, off, blinks slowly or always on.
When a notification is received and screen goes off it blinks slowly.
When is charging led is always on but if screen is off and a notification is received it blinks.
When battery saver is on it blinks slowly, if a notification is received it blinks anyway the same way.
I only tested text notification, and I am using Textra, not Android message.

I found the app " light flow" just after reading this page : it enables to manage the led, : which event (battery full/ WhatsApp/messages...) will make the led blink or stay still, obviously no colour management for this phone and unfortunately no possibility to manage blink speed.
