LG G4 proximity sensor on when phone is off? - T-Mobile LG G4

When taking picture with another phone, I noticed that there is a light blinking on my LG G4 when the phone is in sleep. The location is at where the proximity sensor is.
Does anyone know why the light is blinking? Assuming it is the proximity sensor. Why is it on when the screen is off? Is there a setting to turn it off?

Assuming that it is proximity sensor, you probably have 'knock on' setting that allows the screen to wake up when you double tap on screen while the phone is in sleep mode. With latest updates LG has disabled access to this feature through phone settings but if you search forums or Google, there is a way to access the setting and turn it off using an app 'quickshortcutmaker' to make a knock on settings shortcut then using it to turn off knock on.

tap tap app is a good app but it was a battery drainer because the sensor was always on which ate most of the battery i dont know about the new version i might check it up once again.

[Q] Can we open all time proximity sensor

Some app can use proximity to activate screen on instead of press power button my question is it safety to open proximity always on (the app has option to always turn on, turn on short time..) if I select always turn on may be harm to my O2X proximity sensor or not I don't care perhaps it consume more battery.

Proximity can't turn off screen when covered

I installed a couple of apps for this, like Smart cover https://play.google.com/store/apps/details?id=smart.cover, and Proximity Smart Cover https://play.google.com/store/apps/details?id=com.danielling.proximitysmartcover . Basically I want when the proximity is covered (case closed), the screen goes off, and then goes on when it's uncovered. These 2 apps can do the 'wake' part alright (wake screen when the proximity is no longer covered) but they can't seem to turn off the screen when it's covered. I granted both admin permission. Here are some clues:
_ My proximity sensor is working alright (checked through hidden menu, and it does turn off the screen when proximity covered in-call)
_ Tap tap app can work (touch/wave 2x to lock, same to wake)
So any idea why those 2 app can't work? Thanks in advance.
I use Smart Screen on my Note II with the following settings:
Basic - everything blank (no ticks in the boxes}
Prox - Blank
Sensor - Blank
Start/Stop - Disable in landscape
This works for me and I have not noticed any battery drainage problems.
Please note: I have stock 4.1.2 and no lock screen enabled (my phone never leaves my sider.
This is not my ideal setup as the screen will immediately sleep if i hapren to accidently go to close. I need to pull down the notification menu at the far left or right of the screen. I have tried to play with the delayed reaction settingsand have had contact with the developer about the situation.
I am however happiest that as soon as i open my wallet case the phone is ready for use.

Tried calibrating both in hidden menu and in app, but still there. But using another app, Smart screen off pro, fixed it. Guess it has to be with a different mechanism.
not proximity sensor
I have had the same problem on my 4X but the problem isn't the proximity sensor. I have tried various other apps including orientation and brightness locks. These haven't worked either, I have tried to change lock screen settings and screen time out but these haven't worked. Does anyone have any other suggestions or solutions to this problem?
I use "smart screen off pro" with no problems, all is working as expected....

what lock screen, brightness and permissions settings do you have on your phone other than what is changed within the app?

OK, I dont use a lock screen, never tested if its working...
My settings (checked):
Basic:
- Start on Boot
- Hide notification messages
Start/Stop
- Disable when in Landscape
- Enable only when in Launcher (not necessary, if u want it allways to turn screen off leave unchecked, I want Screen on in Apps, so I checked it)
Vibration:
- Vibrate when screen turned off
Thats all...

[Q] Proximity Switch off

Hi -
My screen was not getting on after making the call so I wanted to check the service menu. I typed *#*#7378423#*#* and accessed the calibration menu and selected Proximity sensor menu.
It showed Autoscreen Brightness On and Proximity Switch OFF. I switched Autoscreen Brightness off (other wise the calibrate option is grayed out) and tried to calibrate the proximity sensor. I got the error -99 and the message that it cannot be done.
1. How do I switch on the Proximity sensor on
2. Will the calibrate option work if the phone is factory reset (there is a message which says - Pls factory reset the phone before calibrating).
Thanks in advance.
I'm tired of this bug too, got first one replaced (yellow tint, black screen + backlight on, proximity sensor) but I still have this sensor bugged, I have to stop the "power button ends call" option because of that!

I found that the switch gets turned on when I place my finger near the Proximity Sensor :silly:
But the screen still does not dim when answering the call nor does it come on again once the call is finished..

Any way to use Ambient display without turning on touchscreen?

As stated above. I have had it turned off since the first week. I keep the phone in my pocket and it will keep waking up, unlocking, and doing things including dialing people.
Maybe I have someone living in my pocket.
Any mod out there? Would like to use the feature again. In the mean time I have been using the led mod.
Ambient display uses the PROXIMITY SENSOR to decide if it should actually turn on. It will not turn on in your pocket.

I know but it still turns on. I do not know if maybe it happens in pockets with white lining or something. I kept getting pocket dials or on a website. Whatever always happens if I have it on.

if the conditions are met for the accelerometer to open the ambient mode screen then it will turn on for a split second before the proximity turns it off. I tested this by using an app that make the phone vibrate whenever the screen is turned off (Gravity screen) and putting a piece of opaque tape over the proximity sensor. Moving the phone to trigger ambient mode caused the phone to vibrate meaning there was a split second where you could theoretically interact with the phone which would cause it to fully wake up and the proximity sensor doesn't cause the phone to turn the screen off unless you're in a call.
Coincidentally Gravity screen does allow you to make your phone sleep using the proximity detector so it can also turn the screen off for you regardless of what is on the screen at any given time. Meaning it'll turn off the screen even if you or your butt is interacting with the screen. And it has settings for pocket angles or apps and whatnot to disable it so you don't lose your screen while watching a video or something.
See. I new there was a way. Thanks!
