Recently bought galaxy m31 and found out that i have to press my phone real hard on my ear to screen to go off during call. I never faced such issue with previous devices. So i searched on google and found *#0*# to check sensor working or not. Sensor is working correctly but there is no fixed place of sensor, seems like whole upper part of touch screen is used as sensor and there is no actual optical proximity sensor inside this phone. It's also clearly written Virtual Proximity sensing. Anyone facing same issue on this device or any other phone which uses this technology and any fix for this?
I have also the same problem. Thanks, at least you dig deeper "virtual proximity sensor".

It doesn't have any separate proximity sensor, rathor the front camera works as a proximity sensor. Try covering the front camera properly.

Hey guys, I'm fairly new here, but there's something that keeps bothering me.
On the left side of the LG there's this 3(?) LED lights or something..
Does anyone have a clue on how they work, or if they even work?
Well, they are not LEDs, they are sensors. Two of them are obvious, one is proximity sensor and the other one would be light sensor. Don't have a clue about the third though...
I'm secretly hoping the third to be a notification LED of some sort
Thanks though

- Accelerometer sensor
- Proximity sensor
- Gyro sensor
eh, what?

That makes no sense. The gyro and accelerometer have no need for visual input, hence highly(!) unlikely that they are what you say they are.
i suspect the first 2 from the left are both proximity sensors, it could be to increase reliability.
the 3rd is the light sensor.
The proximity sensor is based on an IR diode and an IR receiver, just "film" your O2X with a camera and you should see the IR LED flashing.
Thank you guys
Still think they should've put a LED in it though.
My i9305 dropped and now the front glas is cracked. screen & touch are still working, but the glas in front of the proximity sensor is cracked.
it does now always report 0 (attached to ear). Only with bright light in a specific angle I can trigger the proximity sensor, so I know the sensor itself is not broken. So the screen stays black when calling someone.
I tried recalibration: http://forum.xda-developers.com/showthread.php?t=2353972
but it did not change anything.
I dont want to replace the front glass, because I heared it might cause more trouble (with screen, touch and the sensors) - besides the proximity sensor everything does still work fine.
Hey guys, so the last couple of times I've made calls I noticed my screen would stay on during the calls. My ear would be pressing buttons during the calls causing havoc.
So I did a little research and found the hidden menu to test the proximity sensor, which is *#0*# on the dial pad. In doing so if your sensor is working correctly, at the sensor menu, the screen well turn green if the proximity sensor is covered. Mine doesn't, do I just assume my sensor went out or is there a procedure I can do to get it working again?
Hello,
does anyone know how the virtual proximity sensor works?
AIDA64 and other apps say it is a "Ear Hover Proximity Sensor (ProToS)"
The same sensor should be in the Galaxy A51 as I found here
http://stools.gleamolabs.com/sensors/devices/1698
I know that it has no more real infrared proximity sensor.
Just accidentally stumbled over this post. Can you tell me how this ear hover proximity sensor performs? From the name I'd guess it only detects proximity if an ear is actually covering the sensor, and pocketing the device or waving your hand over the sensor will not trigger it, correct?

when I first heard about this phone it sounded like a fantastic device, that impression keeps getting eroded.
I am facing the issue with a sensor while making call after oneui2.5 update.
Sometimes, the screen remains black after the call disconnected. To wake up the screen I used (double tap or power button)
After a restart, it works good. But after some time it became laggy again.
Does anyone face the same issue?
I have a quite different issue with the sensor. My screen doesn't go dark most of the times even when the phone is close to the ear. I guess there's no sensor in this phone, it also uses front camera to adjust the brightness.
Yes, the same issue when close to the ear. I don't know about the separate sensor or camera sensor.
