[Nexus 6  General] JMUT:
K, I think I have steps to reproduce. Looks like you have to enable "Root mode" and "Run every command as root" then enable control of the "charging" LED. Then set up a notification to use that LED. The light doesn't respond to the different blink settings. Always seems to be solid for a few seconds then flashing for a few then back to solid.
[Nexus 6  General] Moostafa29:
Awesome find! I'm assuming it's multicolored?
[Nexus 6  General] jayharper08:
As long as we have the hardware, the software will come in time. :) Loving this! Great find.
[Nexus 6  General] JMUT:
And it's always green, no matter what color I tell Light Flow to use.
[Nexus 6  General] seezar:
The Moto X had one of those with the sole purpose to light up to indicate a charge when the battery was too depleted to power the screen to indicate charging. That's probably the reason it is here as well.
[Nexus 6  General] arcanexvi:
I doubt it. Modern moto devices have used a green/orange/red led as a backup to indicate charging when the battery is too critical to illuminate the panel. Same as the Moto X 2013/14, Droid MAXX, Droid Ultra as well as pretty much everything post RAZR HD. The exception being the Moto G which has a proper LED due to the LCD screen instead of AMOLED.

Still, nice find for those who want an alternative to ambient display.

Edit: Droid Mini had one iirc
[Nexus 6  General] ericsignals:
Mind boggling how it could be on the device but utilized in no way.
[Nexus 6  General] Evo_Shift:
As long as it can eventually be used to give me text/gmail/missed call notification, until I decide to check that notification even if it's 5 hours later, I am a happy camper. I don't even care if it is a single color. I am used to that from an old HTC device.
[Nexus 6  General] SilkyJohnson:
Maybe because Moto makes the phone and they went away from an LED notification about a year ago?

If you don't like the philosophy behind it, start your own hardware company. Lol.
[Nexus 6  General] eep2378:
Hmm...intersting find. I'm sure software could make this more useful.
[Nexus 6  General] ebrown205:
The original Moto X and accompanying Droids had this (not sure about current ones) It was able to be manipulated through tasker. Its original purpose was when the battery was too dead to turn on the screen for the charging animation. Originally, it was only able to be used for battery notifications (charging, charged) but I believe people found away to use it for notifications too.
[Nexus 6  General] acheney1990:
Awesome. Miss my LED.

[Nexus 6  General] thair7391:
Thanks very much for your reply! I'll be sure and thank your post. I had actually already previously paid for LightFlow on my Nexus 5 so I went ahead and installed it. I'm actually shocked at how different the Pro app looks from the Lite. It looks like a completely different application! Anyways, after enabling all three detected devices (mmc:0, lcd-backlight, and charging LED) and setting their brightness values all to 255, I managed to get only a green light when I do a test notification and turn the screen off. I did get the light to work when charging the phone with the screen off but I can't get the color to change and it seems like other people HAVE been able to do so. I wanted to see what I was doing wrong.

Also, this may be related to having Ambient Display enabled, but when i try and use LightFlow to manage notifications, there seems to be a conflict when trying to unlock the screen because as soon as you tap the power button to illuminate the device, it keeps shutting on and then immediately back off. I haven't tried disabling ambient display yet though so that could be it. I'll report back later.

Could someone who's had time to research this deeper explain to me all of the detected LED devices? Again, that's "lcd-backlight", "charging-led", and "mmc:0". Are there more than one LED's in this phone??? I've heard someone mention that there's one under the bottom speaker as well. I'm curious which device I need to enable to make the LED work instead of just brute-forcing the situation by enabling ALL of them lol.

To summarize, what must I do to enable color control if at all possible, and which hidden LED devices actually controls the LED light we need access to?

Thanks for any info!

One more thing.... Any ideas as to what Motorola/Google intended that LED to be used for and why they obscured access to it? IS it supposed to indicate some sort of battery or screen error or malfunction?
[Nexus 6  General] chubby65:
To get rid of the light flow notifications on pull down bar

I installed notifications off from play store and works a treat
[Nexus 6  General] poczynek:
What a brilliant app! Thanks
[Nexus 6  General] chubby65:
Your welcome mate I've been using it since my nexus 4 days
[Nexus 6  General] poczynek:
Best thing is that it still acts as a persistent notification but just hides it. Other ones I've seen take away the functionality.
[Nexus 6  General] chubby65:
I couldn't be doing with the constant notification

Didn't know if it worked on Nexus 6 till I tried it
[Nexus 6  General] VegUnited:
Hopefully the owner is working on some better settings or a mode for just us Nexus 6 people. This app has been consistently the best LED app and used it up until Xposed module performed just a little better on my N5. Glad I paid for it and am excited this is working. THanks to everyone
[Nexus 6  General] dunjamon:
I've not been able to get mine to work. I don't know if the LED works at all. Should the light come on when it's plugged into any USB connection? or only when plugged into the mains?

I've been using a QI charger so that's probably why I've not seen it yet.
[Nexus 6  General] thair7391:
Well it should all depend on how you set your notification to trigger. If you set it to come on when charging at all in light flow for example, then you should see it when your screen is turned off regardless of what source the power is as long as it's enough to charge. Have you made sure to enable run all commands as root,set the brightness values to 255 and enable all three found LED devices?
[Nexus 6  General] dunjamon:
Ah, I may have turned the brightness down. Even without lightflow shouldn't the light come on when charging?
[Nexus 6  General] thair7391:
I would think that it would only come one when charging without use of LightFlow when it's enabled at the kernel level, however I have a kernel installed right now with the appropriate flags to do so and it still doesn't come on without simulating/creating a notification for a charging event. I've also not spent a lot of time researching/testing combinations of options, etc. Hopefully I can play more this evening and get back to you ;). When you use LightFlow for charging notification, do you have to disable ambient display to keep the screen from going on and off consistently when trying to get the phone unlocked? I have that issue currently.
[Nexus 6  General] thair7391:
Just a recommendation, although you don't have quite as much flexibility as with LightFlow, using the TricksterMOD application gives MUCH more consistent and reliable results. Give that a try and see if you're happy ;)
[Nexus 6  General] thair7391:
I really want to understand why Motorola put this LED in their phone!! No ideas? It's even an RGB LED at that! That's just one extra feature that they already paid for to manufacture that they could advertise the device to have yet they did no such thing. I'm baffled! It's actually very pretty the way the grille of the speaker splits it up the way it does. I'm very happy with it :)
[Nexus 6  General] poczynek:
Yes but you can't control per app led like Light Flow just battery charging options.
[Nexus 6  General] thair7391:
Exactly right. I just personally had trouble using LightFlow. I couldn't get colors to work and it caused my screen to constantly lock when trying to unlock it. I think that's a conflict with Ambient Display but for now I like having Ambient Display so I only wanted an LED for charging. When I learn a little more about how everything is working and can fix the conflicts I'll probably start using it for notifications. It's a very pretty light no??!
[Nexus 6  General] kjnangre:
LEDs are cheap. I think that's why they put it in the phone.

Nexus is designed to highlight the features of Android. Ambient display is a new Android feature. That's why the LED is disabled.

My 2 cents.
[Nexus 6  General] thair7391:
You're probably 90% right if not then 100%. You might say, then why not at least offer the LED as an alternative, but as you said, the Nexus is supposed to showcase and to a degree, "force" or "impose" the new way of doing things in Android and Ambient Display would be exactly that. I REALLY like the Ambient display idea if it were just a little more featured and customizable like coming in when the proximity sensor is trigger from either a wave or removing from the pocket. I'm sure that's soon to come in some of our commonly beloved ROM's though. It's amazing how in these new AMOLED screens, the black background doesn't even look like the screen is on or illuminated when ambient display is on because they're all just individual LED's that are powered off. It's probably less power intensive than the bright LED at the top of the phone!
[Nexus 6  General] dtblair24:
Yeah I wish they could have let us use the LED by default. But I too hope for some more functionality with ambient display.
[Nexus 6  General] xxaarraa:
I paid for the lightflow app and tested it the past week or so. It did work relatively reliably - sort of. Couple of problems:

I had to turn off ambient display, which I really like. Screen turning on when I pickup the phone is a very nice feature.

I have reason to believe LightFlow started messing with my screen flickering - as in, I'd hit the power button, screen would flicker to life and then immediately turn off. Did this on notifications screen as well as main app screens.

I would love for Google to release an update down the line that enables use natively of the notification LED and ambient display.
[Nexus 6  General] AmesCell:
I use ambient display and Light Flow. Works fine.
[Nexus 6  General] chubby65:
In led control just check this box and it should work with ambient display

It does here
[Nexus 6  General] thair7391:
I had the same problem as outlined above! I'm just using it for charging right now.
[Nexus 6  General] Ocelot13:
I have the root settings checked...and checked that, but ambient display doesn't work for me :/ can you post what all boxes to check and which shouldnt be checked?
[Nexus 6  General] chubby65:
Hope this helps this is how i had to set mine for it to work
[Nexus 6  General] xxaarraa:
I have all those options checked but still had problems with light flow.

Bummer since the white led at the bottom was one of the features of my N5 that I really liked.
[Nexus 6  General] chubby65:
Don't know what else to suggest mate

[Nexus 6  General] celyko:
I went into my settings and checked, it was already on checked. So I checked it rebooted tried it, unchecked it rebooted tried it, and it still doesn't work at all for hoverchat
[Nexus 6  General] jermaine151:
That was for texting. For a new app like hoverchat, go into notification settings, click the plus icon at the bottom right of screen and choose the hoverchat app. Then choose a color.
[Nexus 6  General] celyko:
Yea I tried that long before I posted here the first time. Hoverchat isn't an option at all. I'm wondering if its some kind of difference in how hoverchat retrieves the messages?

Issue

So I have an issue, Nexus 6 with root, when I test the LED and shut the screen off the LED comes as its set to with the correct color (as long as its one of the working colors). The issue I am having is when actually trying to use, the LED does not come on for the notification. I am using it for textra for instance, when I get a text, the LED never comes on, but when I test the LED for Textra using the test function inside the lightflow app, the LED comes on as expected. Something I am doing wrong? I have turned on root, run all as root, turned on all three found LED's and set brightness to 255 for all three LED's in the textra settings in lightflow, all to no avail.

Edit: I also have direct mode turned on in settings as well for Lightflow
[Nexus 6  General] slyguy2000:
Under Device Settings and Root, I have Direct Mode, Root Mode, Run every command as root, Reset color before change, and Nexus 5 force LED reset, checked

Under LED Control Style, I have both set to Show Highest Priority Only

Under Persistent Icon, I have Run in Foreground, and show the persistent icon in color

My notifications are: (in priority order)

Incoming call (white)

Low battery (red)

Gmail (mixer green + red)

SMS (mixer green + red)

MMS (mixer green + red)

Squeaky Mail {hotmail} (mixer red + blue)

Voicemail (mixer green + red)

Charging (blue)

Charged (green)

Hope that helps...
[Nexus 6  General] wolfnumba1:
Is the persistent notification option required to be checked to get it working?
[Nexus 6  General] slyguy2000:
Not to get it working...but I know the process gets killed after a while, but doesn't when I do have that set... YMMV
[Nexus 6  General] letmedanz:

Had tried different combinations of the settings with no success, but followed what you did & everything is working great.

i have noticed using goole mesenger the light comes on one second goes off

does work but cant figure out only comes on for second.

2. for the life of me i cant get the mixer to work i tried everything . but nothing happens .

constant, is the only option at this point. but stable, so far.
[Nexus 6  General] x0nar:
I performed all steps said by the OP and LED did work. But then I noticed a battery drain. After further research I found out that Light Flow requests Superuser Access constantly when " Run every Command as Root" is ticked. After investigating the logs of Super Su I found out that in a minute about 22 requests were sent. This caused a wakelock which prevented the device from going into deep sleep. Any help is appreciated guys.
[Nexus 6  General] Dabarr:
Actually, you are quite right. I have my log and the whole thing is spammed by light flow request. The attached screenshot just shows a snipped. I could scroll down to almost Infinity. Deinstalled light flow for now.

Thanks for this tip.
[Nexus 6  General] pszyman:
What works for me

- make sure in System settings

Accessibly (Services) > Lightflow > On

Lightflow (must be the paid app)

Settings > Device Settings and Root:

Direct mode - on (checked)

Root mode - on (checked)

Works like a charm.
[Nexus 6  General] Dabarr:
Thanks! But all of these options were ticked. Still the Problem remained.
[Nexus 6  General] vvveith:
Really?

For something as common and universal as a led notification, people go to these great lengths and at an exceptional premium. Unreal, Lollipop other than it's eye candy seems to be a complete waste of time. Google should be ashamed of the short sightedness and brass dictatorship that no one would want to use LED over their current solution. ****ing sucks.
[Nexus 6  General] garyd9:
Lollipop supports led notifications just fine. Please educate yourself before trolling.

The issue here is that the device HAL doesn't support the lights for attention and notification. Likely, this is because the kernel doesn't support hardware blinking for the LEDs (which means there's extra battery drain for software flashing.).

I don't yet know if the hardware supports hardware blinking. I haven't found it (yet) if it does.
[Nexus 6  General] TheySaidWhat?!:
I got lite flow to work recently, but I didn't know there was a charging led that worked?! All notifications work for me, but I dont see an led lit when charging my nexus 6, can you point me to the right setting please? This is important cuz my cable is loose and the led would let me know when the contacts connect, so to speak. I once thought my cable was plugged correctly just to wake up with a battery on 23%.....

Can someone clarify where exactly should we give access to lightflow in device settings? Most people are saying in accessibility, I thought this was for android versions prior to 4.3 but with lollipop i thought it should be in device settings /sound & notification / notification access. Please correct me if I'm wrong..
[Nexus 6  General] jeffreii:
[MENTION=220547]andrewpmoore[/MENTION]

I don't see anything addressing the Nexus 6 in the changelog. Have any issues been fixed? Do we have better control over the LED?

Do we still need to run Light Flow in persistent mode?

So far I don't see many changes - was hoping this was the bug update for the Nexus 6!

Thanks as always,

Jeff
[Nexus 6  General] wtherrell:
Well the update and special settings certainly help, but two things cause me to disable Light flow until solved.

1. Screen wake lag of 8-10 seconds. Ambient on or off, other settings makes no difference.

2. Noticeably faster battery drain. Don't know whether it's the lack of blinking and the LED power draw or the app constantly on and monitoring for notifications.

So close. But no cigar quite yet.
[Nexus 6  General] occtec:
Everyone having issues with lightflow are you enabling notification access in accessibility or in 'sound & notification' / 'notification access'?? I enable lightflow in the latter and don't have any issues ?
