I keep noticing the screen turn on when I'm holding the phone in my hand. I'm not pressing the power button

Settings->Display->Ambient Display
I read it in another thread, but found out it applied to me as well. I had Light Flow installed and it was the culprit. If I use the power button to shut off the screen, ambient display would kick the screen back on. Same happened just randomly while I'm driving down a smooth road (no sudden bumps/shakes) and the screen would randomly turn on. I switched to Light Manager and so far the behavior has stopped.
I stopped using light flow long ago as it would usually cause issues. Let me check out ambient

Yeah ambient I don't need and disabled it

I tried to like ambient display but ended up turning it off. It got annoying when I was holding the phone and my touch woke the phone up from ambient. What exactly is supposed to trigger this thing? Light? Motion?
No lightflow here but I do have a skinomi techglass which I thought I read could screw with the light sensor.
Yeah I feel the same way about the ambient display. I have no real need for it. My screen turned on at least 5 times while I was holding the phone in a cab. Annoying

I noticed this when I was out Friday night at a dark bar as I was lowering my brightness so I wouldn't be blinded by the screen while texting. I lowered the brightness all the way down, and the backlight essentially turned off; at first, I thought the phone turned off sporadically so I turned it back on...but it turned out that the screen was on, but the backlight was off.
After some more investigating, it seems like this is a hardware issue as I did a complete hard reset and the problem persists. Strange, but my replacement should be shipping sometime soon. Has this happened to anyone else?

Accidentally gave you a thanks Lol. Mine doesn't do this, when I go to the wick settings, tap brightness, and slide it all the way down it just gets dim, doesn't turn off.

When your screen goes out are you able to adjust the brightness afterwards?

Yes, but I didn't realize this since I was in a really dark bar. When I got home, I played around with it and noticed that sliding the brightness all the way down to 0 resulted in the backlight turning off, and then the screen turning off within seconds. Very strange behavior.
Just something that I wanted people to be aware of so they can get their units swapped out.
Do you have a custom rom installed?

Nope, stock everything. Locked bootloader, unrooted.
The screen actually doesn't turn off I found out. The backlight is off completely, but the screen stays on for the preset amount of time.
I have noticed and become rather annoyed with this issue.
If it is dark (sometimes not very dark but dim) in my room or outside when I turn my screen on to unlock it (either knock on or power button) the screen will go black as soon as I try to touch it to unlock the phone.
I think it thinks I'm using knock off? But it happens even when I have that feature turned off. I tried my best to explain this. Lol.
Basically I wake the phone touch it and it goes back to sleep.

Proximity sensor blocked will do this. I haven't experienced this myself. Lighting really shouldn't effect it that much.
Does anyone have an issue when pressing the power button, the lockscreen will come back on for about 3 seconds and then turn off again. I can't figure out what is causing this to happen.
Just checked and I don't have this problem. Weird. Have you changed any settings on done a update?
The usual culprit is probably an app that uses notifications and clashes with the Ambient Display.
Try turning off your Ambient Display from the Display settings and see if it still does the same. If not, then you need to find the app that causes the Ambient Display to think it has received a notification when in fact, it has not.
I found that LightFlow is causing behaviour like the one you've seen. I turned off Ambient Display because I like LightFlow more.

So far I hard reset my phone 2x to get it working because my 2nd screen won't stay on after main screen is off. I do even get notifications. I have the settings to stay on. .. not sure what's going in with phone...even my quick charging stopped working. Miss my note 4

Mine goes off if the phone isn't being used. I think it's normal.

Make sure you're not covering the ambient light sensor on your phone. It's right in the upper left hand corner next to the front camera. (To test, with the main screen off and second screen on, If you cover the sensor with your finger on a normally working V20, after a few seconds the second screen should shut off.)
So my guess is if you're sure your Settings are set up correctly, you probably have a faulty or miscalibrated ambient light sensor on your device that's shutting the second screen off, and you should either find a way to re-calibrate the sensor or get your device replaced.

The time should stay on and the notifications should stay on to tell u that you have a message.

There are options under settings display to control when the second screens stays on/off. I have mine in all the time.
under the second screen settings, under settings, display look at the "more" be sure it's UN checked

Same here, what's latest update?
Hi man, I've been searching thru forums all day. Basically, I have the same issues, 1. Not fast charging (only usb-charging) 2. Second screen off when screen is off (despite the settings are set not to)
I'm on the edge of hard factory reset with very limited hopes and my ultimate guess is this is a motherboard issue.
Have you been able to fix yours?
Second screen stays off.!
Yesterday, I was working to upgrade the apps, and install some missing bloated apps by LG Electronics ltd. through the web server, i.e. apkmirror and I don't know exactly what happened. My LG V20 (LS997) Second screen stays off just apparently showing with dark ambient display that is useless at all. The display only shows with media contents by setting up with 'More' as well, and not work even all.
Fixed!! I had the same problem when every time I enabled second screen it would disappear. After looking everywhere I was able to fix it by going to the battery saver settings and pressing on the 'battery saver' option under 'power saving'. Then press 'edit mode'. Make sure 'block use of second screen' is unchecked. That should stop it from being disabled.
My Nexus 6P just started having the screen not light up despite the phone being on. I can feel it vibrate, call it, the notification LED lights up, but no matter what I do, the actual screen will not light up at all. Anyone know what causes this? Thanks for any ideas.
problem with the proximity sensor? ensure that your screen protector is not blocking it. try flashing factory stock and check. if all else fail then it should be hardware issue, request for rma.
