LED Constantly On - T-Mobile LG G4

I've got an issue with my camera flash LED. Sometimes after being in my pocket for a while, I'll notice heat or see the light shining through my pants, and find the LED is on. Not flashing, just constantly on.
The "flashlight" in the G4's settings is not toggled, and when I try to toggle it, it says that I can't use the flashlight while the LED is in use. I can't find any other running apps that would cause this or even use the LED, so I'm stumped, and my battery gets drained pretty quick!
Also, if anyone knows how to turn KnockOn off, I would love to know how. That could actually solve the LED issue too, if the screen is getting turned on and manipulated by my thigh while the phone is in my pocket.
Thanks!

I personally never experienced the LED turning on by itself. Also - Reading your comment, looks like you set the "knock code" and want to turn it off?

No, just the double-tap to wake. I think it's getting randomly activated in my pocket, and I don't use it much, so I'd rather disable it.

[Possible?] Turn Charging Light Off?

Is there a way to turn off the charging light?
I usually charge my phone during the night and the glowing light is pretty, but annoying when trying to sleep.
I wish I had your problems ? What about
1) putting it in case
2) put it facedown
3)
4)
n) solutions ...
- Don't have a case, don't want it.
- Don't really want to put my phone face-down, better for my screen and when I wake up, (well, trying to) I prefer to have the buttons on top
Ik know it's not a big thing, but it would be nice if there was a way to turn it off.
Yes but i don`t think it`s possible but maybe someone will dig up registry key
bump it up, as I also wait for a solution (as battery live i so poor, have to recharge it every night, beside my bed)
I have found these.
They are not made for Diamond, but they WILL turn off the LED.
Optional_LED_Killer_3.1a (haven't tried it)
no2chem nueLED_1.5 (tried it, and it turns off the LED, but if you add other LED's it will crash)
Led_Killer_3.1 (tried it and it works, but after a while (I think after reset) I got an error message.

Where did you source the above from and any further updates on whether they work?
I've got this same problem and it drives me crazy! I shelled out for a Diamond stand next to my bed (used to lay the phone face down while recharging) and it's very convenient - except for the flashing lights every 5 seconds lighting up the room.
I've had to resort to putting a sock over the phone in the stand each night...!

Backlight turns on randomly

Does anyone else have this happening my screen will randomly turn on after i press the button on the top to turn it off? it is very annoying at night it makes me think i have an incoming call or text message and being that Im on call 24x7 sometimes have to check it everytime it happenes which is about ever 10 to 15 minutes????
I searched on here already and couldnt find anything?????
any help?????
yes, that's probably normal behaviour, since the SCREENN-OFF button also works as SCREEN-ON button, whatever necessary...
but my screen doesn't turn on randomly...
my tip: just put your device in a thick wool sock and put it face down on your desk ;-)...
another possibility is, that if you charge it over night and the plug isn't fitting right then the screen may turn off because it constantly thinks it's plugged in and out...
Best Luck and nice dreams
Regards
not only when plugged in
actually it doesnt only happen when the phone is plugged in it happenes all the time

mine does it too upon occasion. i think it has to do woth background processes running, or your phone is roaming for alternative towers.
mine does it too. I have the Sprint CDMA version. Someone on a different forum thought it might be the phone looking for a signal. But no one was really sure. Haven't been able to find much useful info on it anywhere.
it's switching towers...my Mogul did it too.
is there any way to make it stop
In some of the aboce cases it can be that someone is trying to make a video call to you while Phone skin is disabled.
I also have this problem. My screen will turn on from time to time without any obvious reason. It's especially annoying at night... I have my phone in a cradle on my nightstand, so when the screen comes on the whole room lights up! I've resorted to keeping a shirt over it at night.
I tried setting the phone to 100% roaming since my Sprint signal is low in my apartment and I read somewhere that the phone will turn on when it switches towers/service, but alas it did not help me.
ANY IDEAS FOR A FIX?

How to fix screen backlight on HTC One m7

I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.
i used the app both light senor and proximity sensor are working fine
any other tips that i can try

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!
Tip: use a led flashlight to see what's on the display

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.
Is the display not broken?

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?

Notifications turn on screen

I have been searching looking for way to make this work with no solution.
I have disabled AOD since it is consuming battery heavily and wanted notifications to behave as on stock android where they turn screen on. My note 8 is receiving notifications and LED turns on, but screen doesn't. I have to manually turn it on to be able to see the lockscreen notification.
Is there any way to make this work?

I use "Dynamic Notifications". It lights up notifications when screen is locked. There's a certain amount of customisation, including screen on time. Used it on many of my phones including Note 8.
Wait.. You want the screen to turn on for every notification?
I hate that... Some apps even ignore the settings either way.

Same here, that would drive me nuts if the screen turned on for every notification. It's bad enough the screen turns on everytime the phone is plugged in/unplugged from USB or from a wireless charger.
Shouren, you can try snoozy charger app to manage the plug/unplug screen on issue

Thanks. The rom I'm using is actually supposed to have that disabled but I don't think it works for wireless charging, only cable. I never never charge with the cable anymore. But whatever, I prefer not to install apps just to disable one minor thing.
I understand you, I also prefer wireless, but, it works with wireless too
There must be a build prop tweak or something but I can't seem to find one right now.
Maybe a PM to a nice dev and they could tell you where to look. Report for community if you figure it out

Random screen auto turn on with do not turn on display in notification

My red magic 3 will randomly turn the screen on even with the option to not wake up the screen in every settings I could find. I have seen it happen when I'm driving or walking and even just having the phone on my night stand.
Then screen will turn on and there's no new messages or notifications, it just turns on.
Any ideas as to what I could try?
My friend has this exact same issue! We both have the same phone, mine does not do it but his does. Just, randomly the screen turns on, doens't seem to be related to notifications or anything. If anyone knows what's causing this, it would be appreciated. Thanks!
