LED (for notifications and charging) no longer works - Nexus 4 Q&A, Help & Troubleshooting

Hi all.
I installed Nitrogen OS Oreo with the full knowledge that the LED didn't light up when charging. However, with my brief use of it, the LED never lit up for anything. Since the battery life wasn't to my liking, I installed Fake Nexus 7.1 ROM. The LED still never lit up.
So, I installed Google's stock image for 5.1.1 LMY48T, figuring that should fix things. That didn't work either. "Pulse notification light" is set to on.
I installed LED Tester and it's able to make the LED light up in all its glorious colors, so I don't think it's a hardware issue.
The LED worked fine before installing Nitrogen OS Oreo.
Any idea what happened? Anyone know how to fix it?
Thank you.

Wipe everything and install stock and check.

Installing the stock image wipes everything. Thanks, though.
Since the battery life of the stock image isn't so great, I thought I'd be adventurous and install LineageOS 14.1. last night Somehow doing that has made the LED work again. I'll leave it installed for now and see if I like it.
So I guess the problem is solved, though it's still a mystery.

LED doesn't work since moving from CM12.1 to stock 5.1.1

Hi,
After some issues with CM, I moved to stock 5.1.1. I added xposed and gravitybox for my desired tweaks, and now everything works as I like it except the LED.
It's just dead. Nothing gets it to shine except when charging (so I know it's not a hardware issue).
I've tried with GravityBox's Ultimate Notification feature (I have the paid version), and also other apps like Light Flow, Light Manager, and LED Test, but nothing turns the light back on.
Any ideas? something else to try?
Thanks.

LED flashing when turning on my phone, Please Help

Hi, so recently i flashed a custom rom called [JDCTeam][STABLE][5.1.1][26 January] Optimized CyanogenMod 12.1 builds (http://forum.xda-developers.com/gal...lop/exclusive-antaresone-alucard24-s-t3066696)
on my phone and since then, everytime I turn on my phone a variety of light like light led just flashes before my phone turn on so i was just wanted stop them but don't know how,:crying::crying::crying:
If anyone can help me, that will be super awesome. Thanks for reading this
It's normal.
But there should be an app called JDC Toolbox that gives you some LED settings.

LED Control (Nougat)

Hey all! I know at least a few of us are playing with Nougat on our phones currently. Others have put off installing Nougat because Xposed isn't (yet, hopefully) compatible with Nougat. I went ahead and upgraded, but was reminded how much I missed GravityBox when trying to use my phone last night. I generally charge my phone overnight, but in the dark the charging LED is way too bright and hurts my eyes. None of the LED controlling apps I found in the Play Store, even one that required root, did anything.
So long story short, here you have it. If you root your phone, and install this apk, it'll let you enable/disable the LED at will. I know for sure it works on the Z5C running stock Nougat, and it might well work on other phones and OS versions, though I haven't tested anything else yet.
If there's any interest, I'll continue to develop and test it further. I have plans to add a screen brightness slider, since I found how to dim the backlight lower than the usual lowest setting, and this also helps in the dark, and works better than screen filter apps. Other suggestions would be welcome.
Hope this helps someone else out!
I need to decrease the Notification LED brightness

Thank you I've actually given up on Nougat for the time being and am using Marshmallow as my daily driver, so I haven't touched this in a while. I would suggest though that you check out f.lux for rooted Android, because it really helps me out at night

[Q] How to activate the led notification on stock?

So recently I went from stock to Lineage and now (after Nougat) I'm back at stock.
When I started using Lineage all of a sudden the green (charging) led also worked for notifications.
I really liked that. Is there a way to activate that again, but on stock? I can't find anything online...
Thanks
Edit: Using a XT1580
No. That's a custom ROM feature. In stock is only used as a low battery notification, and there's no way to control it.
Same thing with Quark, the predecessor to Kinzie. All the custom ROMs use the green low battery indicator as an LED notification light, thanks to @bhb27 (one of the main Quark devs). That's probably where the Lineage dev for Moto X Force got the code from.
Someone could probably make an Xposed or Magisk module that uses that code, but right now I don't know of a way on stock firmware.

No notification LED (LineageOS on OnePlus 1)

Well, the name says it all. Upgraded my OnePlus 1 to 16 from 15.1 (flashed over the old ROM + new gapps) -- seems to work overall, but no LED, including when charging. Everything was fine on 15.1. Can anyone confirm this as a bug that will be fixed, or do I need to tweak anything? LED turned on in the settings from everything I could see...
Thanks!
Same here...
Also confirmed on a friend's Oneplus 1, same type of upgrade as mine (flashed over 15.1). Latest nightly did not fix this.
Same situation here, also camera app not working. I installed open camera.
LED seems fixed in the latest nightly, camera app working (and was working before).
Same here, it's a known defect.
LED seems to work now. Only when I get SMS it will not use LED. Might be fixed sooner or later.
