Background:
I previously had an old Nexus i9250 which had an LED and I'm missing that badly, despite the Moto notification.
However, the Moto X 2 (2014) has a LED hidden under the earpiece, but it is normally only used to indicate charging (this is similar to the Nexus 6, but the Moto 2014 LED is just green, the Nexus-6 seems to have a hidden multi-color LED too).
On rooted devices the LED can be turned on by writing a value to a system file:
echo <brighness> >/sys/class/leds/charging/brightness
(<brighness> is some value betweeen 1 and 255, for testing in an adb shell it needs to be issued from su)
The LED can also be activated using the LightFlow app (see thread here: http://forum.xda-developers.com/showpost.php?p=59198021&postcount=22)
Here are instructions for the Tasker app (which allows more flexible control over the LED):
1) Create a Tasker task "Led On If Screen Off"
- Task-Type "Code>Run Shell", set Use-Root to "on", command: echo 64 >/sys/class/leds/charging/brightness
- EDIT: as someone suggested here, alternately (instead of the run.shell command) you can add a Task: Alert>Set-Light>Charging and set slider to 64
- fill in the IF-section: IF %SCREEN equals off
- (the number 64 in the command is the brightness, it can technically run from 1 [dim] to 255 [battery consuming])
2) Create a task named "Led Off"
- Task-Type "Code>Run Shell", set Use-Root to "on", command: echo 0 >/sys/class/leds/charging/brightness
- EDIT: as someone suggested here, alternately (instead of the run.shell command) you can add a Task: Alert>Set-Light>Charging and set slider to 0
3) Create a Profile named "Notify Led On"
- Profile-Type "Event>UI>Notification"
- Owner Application "*" (or any you may like)
- Assign profile to perform task "Led On If Screen Off"
4) Create a Profile named "Notify Click Led Off"
- Profile-Type "Event>UI>Notification Click"
- Assign it to perform task "Led Off"
and/or
5) Create a Profile named "Screen On Led Off"
- Profile-Type "Event>UI>Display>Display On"
- Assign to perform task "Led Off"
Violá ... Tasker will turn on the LED if the display is off and a notification arrives. (Of course other triggers like "State>Battery" can also be linked to the "Led On" task).
Enjoy
Can you say why my echo <brightness> keeps coming back to 0 by itself?

It should be something like
echo 255 >/sys/class/leds/charging/brightness
And needs to be running in root or superuser, so make sure the command is set to run as root (and you have Tasker allowed in SuperSU or similar apps).
fhreire said:
I don't have the Tasker app, I tried a cracked one to test but it didn't ask me permission for SuperSu, so I guess it's not working, innit?
Click to expand...

The Use-Root flag must be set in the task.
Probably su echo 64 >/sys/class/leds/charging/brightness as a command will also work.
Or your cracked version is broken (Tasker is worth the money anyway and you can get a refund from PlayStore within a few hours if you don't like).

Great one! Was looking for some way to turn it on and off.
BTW, you can make it blink softly (like Moto G 2014 and others) by changing the action Led On If Screen Off to the following:
1. Task-Type "Code>Run Shell"
- set Use-Root to "on"
- Command: echo 1 >/sys/class/leds/charging/brightness
- fill in the IF-section: IF %SCREEN equals off
2. Task-Type "Code>Run Shell"
- set Use-Root to "on"
- Command: echo 25 >/sys/class/leds/charging/brightness
- fill in the IF-section: IF %SCREEN equals off
3. Task-Type "Code>Run Shell"
- set Use-Root to "on"
- Command: echo 255 >/sys/class/leds/charging/brightness
- fill in the IF-section: IF %SCREEN equals off
4. Task-Type "Code>Run Shell"
- set Use-Root to "on"
- Command: echo 25 >/sys/class/leds/charging/brightness
- fill in the IF-section: IF %SCREEN equals off
4. Task-Type "Code>Run Shell"
- set Use-Root to "on"
- Command: echo 0 >/sys/class/leds/charging/brightness
- fill in the IF-section: IF %SCREEN equals off
6. Task-Type "Task>Wait"
- 10 seconds (or the desired blinking interval)
7. Task-Type "Task>Goto"
- Type "Action number"
- Action number 1
Then, just add the following to the Led Off task:
- Task-type "Task>Stop"
- Task "Led On If Screen Off"
And it should blink until you tap the notification. My hope is that it will decrease the battery consumption to a minimum level.
Hope it helps!

I did my own version so it blinks really smooth, with fade-in and fade-out, and repeating every 5 seconds.
To ensure compatibility, install busybox!
Same as @joaoeder, but put this on Led On If Screen Off
1. Task-Type "Code>Run Shell"
- set Use-Root to "on"
- Command: (ensure that you copy everything in a single line. I recommend to copy & paste )
Code:
l=1;while [ $l -ne 32 ] ;do echo $l >/sys/class/leds/charging/brightness; l=`expr $l + 1`;sleep 0.01;done;sleep 0.5;while [ $l -ne 0 ] ;do l=`expr $l - 1`;echo $l >/sys/class/leds/charging/brightness;sleep 0.01;done
- fill in the IF-section: IF %SCREEN equals off
2. Task-Type "Task>Wait"
- 5 seconds (or the desired blinking interval)
3. Task-Type "Task>Goto"
- Type "Action number"
- Action number 1
Now the led will smoothly fade in for 1/3 second, keep on 1/2 second, and fade out for 1/3 second.
No more crappy slow and noticeable brightness steps! It's almost identical to the stock notification of most phones.
I had issues with tasker, I discovered that I had to reboot the phone each time I made changes for applying them, otherwise it just didn't work
If you want the led to be on for more time, change sleep 0.5 to whatever you want (0.5=1/2 second, 1=1second, 2=2 seconds...etc)
No need to use shell, you can use the build in taster function.
It is under Alert > Set Light, from the drop down menu select charging and use the slider to set the brightness of the Led.
I thought it was said the OS couldn't access this light, nice!

Thanks.
Can this be applied to the 2013 moto x?
Haven't had any luck with tasker yet, i cant get the prompt for root to show. gonna try lightflow and see if i have any luck with it. Do i need to disable moto display and ambient display?
EDIT: Fiddled with lightflow for a while with no luck either. Finally got tasker to show the prompt for SU but it isnt working either. Can't figure what I am doing wrong.

Great dude!
wasnt able to get it working on moto x 1st gen either. obviously the implementation differs from the one in the moto x 2nd gen, allthough the paths and the triggers are the same. would have been great to get a notification led....

I can't seem to get this to work on my 2nd Gen Moto X. I can get the tasks to work just fine (turns on/off the LED) but the profiles with the notification and notification click don't work. The light doesn't come on with a notification, with screen on or off, and if I manually turn the light on through the task, I can't get it to turn off with a click on a notification. Any ideas?

Using moto display? Clicking a notification through moto display isnt registered as notification click unfortunately.
Try setting notification + display state off to turn on the led for notifications.

Guys, I'm having some issues with the led.
First I've rooted my phone and tried to make the led blink using tasker and Stock ROM, but I have no success.
The second time, I've flashed temasek ROM (with some led options like blink duration and speed) but didn' t worked too.
The third time I've tried with tasker and the custom ROM. No success
To sum up my situation I can't make the led blink, it turns on but still on continuosly when the screen is off.
I would like to know if someone made the led blink with success.
Sorry about bad english

Hi all,
This may probably be normal but need to check with others.
When you on are on low battery status and the orange LED notification blinks does your phone blink for like 12 or 13 times(can't remember it exactly) and then the LED notification disappears i.e. no more flashing or colour in LED?
I thought the orange blink LED would blink continuously till battery expiration or do I need to change a setting?
Can anyone else confirm the above on their HTC HD2?
Thnx
Hope this helps others:
http://forum.xda-developers.com/showpost.php?p=5047426&postcount=6
Just to add to the above you need to do the below to get the notification to appear in the notification settings of the HD2. By default it ain't there and you need to use a reg editor to modify the key below to add a new string and name it to Low battery warning.
The instructions are below to getting the amber LED to continuously blink all the time. Mine was only blinking a few times and then disappeared and I was wondering why does it keep disappearing. Hope this helps others...
Using a regeditor I am using taskmanager:http://www.dotfred.net/TaskMgr.htm
1. Search for the key HKEY_CURRENT_USER\ControlPanel\Notifications\{A877 D663-239C-47a7-9304-0D347F580408}\.
2. Next to Default the first option in the below window highlight it hold with finger and select edit and select value type REG_SZ. Then leave value name blank and type in Value data: Low battery warning tap on tick. Close task manager..
3. Now goto settings in HTC sense -> settings->menu ->all settings -> Sounds & Notifications applet -> Notifications tab, choose Low battery warning value from the Select an event drop-down menu and set flash light to whatever you want.
This way your orange LED battery low light blinks all the time now

Nice one! thanks for finding that
I have the same problem with low battery notification.
Few weeks ago it worked as described in users manual, blinking red until the phone turns off.
I don't know what happend but now when the battery is below 5% the led blinks about 12-13 times in red and then turns off, but the phone is still working.
I tried a reg hack and set the led to blink without limit but it doesn't work.
I also did a hard reset but the problem still exists.
Does anyone have an idea what could be wrong ?
TIA.
This thread has been dead for a while but I havethe same problem of the low battery notification blinking 13 times and turning off. I did the reg edit, using CERegEditor initially, and then I tried it again with TaskManager.
Both times it resulted in the low battery warning showing in the drop down menu BUT even when I set it to repeat infinitely (I'm using a Chinese ROM so I don't know what it says exactly on English ROMs) it still only flashes 12 - 13 times! Same problem as et1.
Did I follow the instructions wrong both times? Has anyone found a solution to this?
Any insight into this would be greatly appreciated.
Moto G 4th gen is having hidden LED notification light in it just near the fingerprint sensor.Hope so soon there will a way to control it.The same hidden LED is also spotted in Moto G3 ,Moto G2 and moto X play. :good:

Hey,
After a little experimentation, I found that you can use the Light Flow Legacy app to control the led. (https://play.google.com/store/apps/details?id=com.rageconsulting.android.lightflowlegacy&hl=en)
Once you've installed it, you must give notification access.
Go to menu > settings > Device Settings and Root > check "root mode" and "run every command as root".
Then go to menu > settings > LED control > Additional LEDs found > check "charging control"
Now, go to menu > notification settings > click the 3-dot menu on any of the items in the list > settings
In the next screen, swipe right to find a tab called Light. Find charging LED and click on it. You'll have an option of turning it "solid".
You also have an option to set its brightness, but that setting didn't change the led's brightness.
On the top right corner, you have an option called "Test". Click on that and switch off your display.
You should see the charging led light up.
Cheers.
Any Rooted User Can Try This App.
http://forum.xda-developers.com/android/apps-games/4-3-led-control-motorola-devices-t3036823
I think we can use the LED once the device is rooted.We can use apps like " Light Flow Legacy" and "Moto LED".Not sure if this will work or not.
But these apps worked on Moto G3 so i think these will work on the 4th gen as well

I'm just curious but why is that small, barely visible in full light led any better than a notification turning your screen on.
For the simple fact I would notice my phone blinking at me without having to pick it up. I'm not sure I can explain it better than that other than without this feature I would be picking up my phone all the time for fear I have a missed message. I don't want to be doing this.

It only light up the screen when you first get the notification. If you missed it, the only way to access is to physically move the Moto g4. A pulsing light is always on. The amoled moto's have the consistent pulse notifications which sought of makes the light unnecessary. I too hope moto will activate this feature in a future update.

Thanks to Sai_D for the configuration info for Light Flow Legacy. Works for me on XT1641 (rooted of course).
I had installed it earlier but didn't have it configured properly and so it wasn't working.
Notification LED + Active Display is a great combo -- the LED tells you that you have a notification and then a simple nudge of the phone activates the display so you can see what it is.
Hey guys, someone can tell me if Moto G4 PLAY has hidden led light too? I'm really looking forward it! Thanks!
So as the lowest screen brightness of our beloved Pixel C is just a little above the light of a thousand suns, I researched how it can be lowered.
But mind that you WILL NEED ROOT for this to work. Also mind that I'm not responsible if you **** up your device.
1. Root your device
2. Install any Terminal that can work with the root OR use adb
3. Switch to root user ("su root" OR "adb root")
4. Execute this "echo 3 > /sys/class/backlight/lpm102a188a-backlight/brightness"
5. Profit!
Instead of the "3" in that command you can use any value from 1 to 255.
BUT I strongly recommend NOT to set the brightness to 1 because your backlight will turn off.
Also on value 2 my display flickers so I would be careful with this.
Have fun without bleeding eyes!

https://play.google.com/store/apps/details?id=mobi.pruss.superdim&hl=en_GB might do the same thing for you guys. As far as I know it's just a wrapper around this sort of command.
There is a "settings" command to adjust the adaptive brightness value. I haven't tried this, but the following terminal command might work:
settings put system screen_auto_brightness_adj (value between -0.5 and +0.5)
Root is needed, of course. I found this in a tasker thread on reddit: Edit: I cannot add links yet. Search for "reddit tasker how to replace some secure settings actions"
Anyway to make this permanent? Every time I switch off and on the screen, it becomes brighter again. Thanks
Testes with Xiaomi Mi9 use this command:
echo 3 > /sys/class/backlight/backlight/brightness
Just to let you guys know, you can have the charging indicator as a notification light if you have
1) root
2) tasker or another similar application.
The command to use the led is
Echo X > /sys/class/leds/charging/brightness
X to be substituted for values 0,1,2,3.
0 = off
1 = fast blink
2 = slow blink
3 = solid
Unfortunately the led is only white but beggars can't be choosers.
You need 2 profiles, one for when the notification comes on, and one for when the notification is removed.
I have a basic understanding of Tasker. Once these 2 profiles are created do I need to do anything else for my apps such as messaging or email to use them? Would you be able to attach your profiles?
Profile: Notification (2)
Event: Notification [ Owner Application:Facebook, Instagram, Messenger, Messages, TypeApp, WhatsApp, Push Notification Tester Title:* Text:* Subtext:* Messages:* Other Text:* Cat:* New Onlyff ]
Enter: Light (3)
A1: Run Shell [ Command:echo 2 > /sys/class/leds/charging/brightness Timeout (Seconds):0 Use Rootn Store Output In: Store Errors In: Store Result In: ]
Profile: Notification Removed (4)
Event: Notification Removed [ Owner Application:* Title:* Text:* Subtext:* Other Text:* Cat:* ]
Enter: Light Off (5)
A1: Run Shell [ Command:echo 0 > /sys/class/leds/charging/brightness Timeout (Seconds):0 Use Rootn Store Output In: Store Errors In: Store Result In: ]
Thank you for the quick reply. Would it be possible for you to backup your profiles and attach the xml file here for easy import?

Sometimes, the LED lights up for 2 seconds and goes dark for 2 seconds. Other times I see the LED blinking for a split second, and going dark for ~3.5 seconds. Something seems to interfere or the LED reacts slowly at times.
Btw., I am running the official Lenovo Marshmallow.

Great find! Unfortunately it is not working overly well on my Moto Z Play. The LED blinks very erratically. I even tried scripting my own blink pattern with the following code:

It's doze or some stock power save feature i think. I have the same problem on stock. Sigh.

I don't know if you have xposed installed, but if so, you can try the AppContext module.

The notification detection isn't the issue, the system seems to go wonky when the screen goes off, its like the led timer isn't consistently firing off the alarm.

In order to test my task, I ran it with "screen on". Therefore I didn't even think about doze or other power saving mechanisms.
Damn-it! It is working correctly now
I didn't change anything in tasker. I use the following settings: "Run In Foreground -> On", "Show Notification Icon -> On", "Use Reliable Alarms -> Never" and "Reduce Resource Usage -> On"
Weird... Mine only seems to go wonky when the screen has been off for a while.
Hi,
I've recently upgraded from N to O (8.1 OPM5, rooted), and ever since then I have no LED notifications at all.
Things done:
1. Enabling "Blink light" in notification settings.
2. Enabling/Disabling the "Ambient display" setting.
3. Checking w/ GravityBox' UNC (I have the pro version).
4. Checking w/ 3rd parties like LightFlow and Light Manager.
None of these worked, and the LED was never on at any color. When using Nougat I had no problem with it.
Any ideas?
Thanks.
This is what I've seen on another website:
"To start...Oreo notifications are very different from Nougat. Not only do you need to turn on the LED as you have already done, but you also need to go into each individual app and make sure you have the same thing turned on.
Here is one example...
Go to Settings > Apps & notifications > App info > Gmail > Notifications > UNDER Miscellaneous tap on "Miscellaneous Make sound" and a new window will open and in here is where you make the individual app adjustments where you turn on "Always pulse notification light" > then go back one screen and tap on "Attachments Make Sound" and another window will open where you make the same adjustments per app as you just did.
The key here is that not only do some things have a toggle to turn them on or off, but those same toggles will open another windows when you tap on the words themselves which gives you more notification options than you thought were even available. Be patient and you will get it."
Thx for the reply, that's a good lead.
Unfortunately (for me), all settings are "on" for "Blink Light", and still the LED never turns on.
same here :/ everything is on but LED still doesnt work
