[SOLVED] notification LED not working? - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

I've turned on LED notifications in my device Settings (for example, to show when the phone is charging) and in apps such as Gmail. But the only time the LED notification turns on is when the phone is rebooting. I've tried the LED Tester app, but it can't get any response from the notification LED either.
Is my phone defective, or is this a bug in all Note 3s, or am I doing something wrong?

Sometimes when I change settings they never work until I reboot the phone. ..

I don't know if it helps but mine works properly (while charging, kik messenger, Skype) didn't try gmail though. I doubt its a bug.

Thanks, but rebooting didn't help.

Thanks, it's helpful to know that it's supposed to work. Now I'll try to narrow down the problem.

Turns out it was my mistake. I'd enabled Blocking mode to reject phone calls from unknown callers, but I inadvertently checked the boxes that suppress all LED notifications. Works fine now that I unchecked the box.

LED on mine do not show a solid color, mixed up. Other thing I noticed sometimes, the red charging LED is dim sometimes bright when charging.

Screen randomly glows when screen is switched off

Hey on my Xperia Z stock rom nothing flashed, when it is in standby (screen off) randomly the screen glows and does not stop, like the screen is still off but it's like the back light has come on? is this normal? seems to be a power wasting thing to me. unless i look at it from a slight angel (during the day) i can not actually tell it's on, i'm assuming this is why my screen is using 60+% of my battery is there a fix for this?
Are you using any power saving mode?

Stamina mode.
I have the exact same thing happen, and it is definitely a pain as like you say you can only notice it when looking at an angle, and as I have a flip case on mine I only notice while charging. It is just a case of pressing the power button twice to turn off but that is obviously only when you notice it's doing it! lol
I use stamina mode on mine (which is great) but not sure if this is anything to do with the backlight being left on as it only does it sometimes?
I had this issue when i first got my phone ,and not anymore.Not sure how it solved cause i did lot of factory reset and flashing firmwares.
Are you using light flow or any third party apps?
Sent from my C6602 using xda premium
I get this too. I get it when it's locked and it comes back on. Also when I unlock the screen sometimes this happens and I have to turn the screen off and on again to fix it.
Happening here also but not often. I thought it was low battery mode but happens when it's disabled as well.

No i'm not using any third party light apps, seems like this may be an actual bug if multiple people are experiencing it
I have only done one reset/repair to fix the LED notification light bug.
Hope this helps
I know how to fix this. I have an xperia z1 so im not sure if my problem is the same but i use my phone as an alarm so i notice at night the screen is glowing while its standby. If you go to settings or maybe you have it in quick settings go to brightness and deactivate "adapt to lighting conditions" then it should be a black screen woth no glow in standby mode

Active Notification inconsistent

I don't know if others are having the same problem but I have a stock phone not rooted and active notifications enabled
Every time I place my phone upside down and then a few seconds later turn it over it will show the time..no problem...everytime
On the other hand if I leave my phone aside faced up ..after the screen goes black I would say 8 times out of 10 the clock shows up when I pick up the phone.. I'm assuming the sensors know that the phone has been picked up a d activate the clock display....sometimes the screen remains black even after picking it up and giving it a gentle or hard shake.....bug ?

I too am experiencing this especially when there are no notifications which seems like a waste to me.
Can you guys check your sensors? Maybe something's broken. I'm having sensor issues myself, and have noticed inconsistent notification behavior as well.

I don't turn my phone upside down. But just sitting there face up it it completely and randomly light up the notifications

That's normal behavior.

[Q] Control notification LED?

Has anyone found an app that gives us better control over the hardware LED?
I'd like to have the notification light periodically blink when there's an SMS message or missed call, (and maybe some of the other important notifications), and the default settings offer so little control as to be useless. <rant> Seriously, why would I want a LED to tell me if the phone is charging, I can see damned well that it's charging, there's a cord attached! </rant>
There's the LEDBlinker app, which has all the options i'd want, but when I put it into test mode, it doesn't blink the leds.
Has anyone else tried to do this? Has anyone had any success? It's a cool hardware feature, that I think i'd really use - but it's hobbled by the crap configuration options Samsung gave us.
Thanks

Samsung prevents the LED notifications from working unless the screen is turned off. I'm using Light Manager (the dev participates on this forum), and so far it works fine in "alternate" mode. When you test the LED settings, a pop-up tells you to turn off the screen, and only then will the test work (and it does).

Thanks - turns out I'd turned the LED off in settings (along with the options to use the LED to show charging status). /facepalm

Light flow... Does it work?

Anybody tried light flow yet?
Works like a sharm! No root necessary. The new notification light is much better then the speaker built in thing from the z1c.
Tested "Light Manager" and that works, too.
Can't seem to change the charging led though
Yup, I have the paid for version of Light Flow setup and working perfectly!

I just tested and i can't get light flow to change the charging LED. It doesn't even turn off if you disable the notification light in Androids DIsplay settings.

To bad. It's keeping me awake at night and really holding me from buying a dock.

I've been able to sort of fix this using Light Manager. I select a really dark color (almost black) for both charging and fully charged set it to be always on (no blinking).
It's kinda finicky, though, and sometimes it takes a few moments until it LM takes over from the built in notification light. For me, Light Manager works better than Light Flow. YMMV, it's possible to do this with both of them.

Just wanted to say that I have done this with Light Flow and it works great. It still shows the default charging colours when the screen is on, but when it's off it uses the ones in light flow. The trick is to use anything but totally black. I set it with the HEX code to FF000001 and it works.
That is on a full-size Z3 but I can't imagine the hardware is different regarding LEDs.
I use light manager and it does work with a dark colour to set the charging/charged led colour. (dark blue)
BUT
When I use sleep mode (so I get to notification lights) the charging/charged trick doesn't work ....
So I have to dissable sleep mode
anyone has a solution for this?
Lightflow doesn't seem to work for me neither.
Is there any other option without rooting the device (no option, as it's for the device of my girlfriend)
Works perfectly for me. Keep trying. Make sure it's enabled in settings security notification access.

Hmmmm very good point. Thx for the advice. I think I activated this after the installation of Light Flow. I remember some red info message bugging me But to be honest I can't find this setting anymore. Where can I reconfigure/ review this?

Ahh Thx But this doesn't seem to be the problem. Checkbox for Lightflow is checked there.
Will keep trying to get it working.
Thanks a lot for the help so far.
Light flow works like a charm for me and love how I set colour per notification type it's the only app that works 100%

Blue light filter

Just noticed, the blue light filter takes a few seconds or more to engage after screen is brought back from standby mode. Pretty irritating.
Example viewing a page within Samsung browser, screen times out ( has to time out )then I press the home button to turn screen back on, blue light filter is off now for a good few seconds or unless I go into the settings screen.

Mines instant also, just not instant when waking the screen with the home button after it times out.

I thought it was just me. I looked around to see if anyone else was having it in other threads but I'm glad I'm not the only one having this issue. Mine is really delayed that I need to turn it off and turn it back on. Sometimes I wait over a minute til it activates so I just end up having to toggle it off and on since it's faster... Unfortunately

I have this issue. Also, even with blue light filter turned completely off, it still engages at dark. Anyone else?

What you have could be Google books issue that you have , it's been discussed on here in the past. It's complete different to what my issue is
