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?

@xmoo
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.

We all know that the nexus one has in the top left hand corner 2 types of sensors:
1. Proximity Sensor
2. Light Sensor
I dont know which one is which but in this demo of the day 2 conference one of them lights up during the demonstration of a call. Can someone explain why that is?
Take a look at timestamp 23:02 in http://www.youtube.com/watch?v=IY3U2GXhz44
That could very well be an infrared light flashing and being picked up on the camera.
Is that how the proximity sensor works? Sends out flashes and looks for a reflection?
Could possibly do that when a call initiates and whenever motion is detected to check the proximity.
Try it yourself. Start a call while looking at your phone through a webcam. I just did and can see it flashing while the call is active. It doesn't flash the same way as on the phone in the demo, but more of a steady flashing on mine. Could be that it is more efficient in FroYo or the version they were running.
Nice find, I overlooked it when I watched it earlier.

Not sure which sensor it is but
1) infra red light does show up when you look at it through a lense with filter/coating/film. Try looking at your tv remote with your digital camera.
2) the blinking could be the video framerate
I think it's most likely the proximity sensor. The light sensor should just take in data and never give out any type of signal. Also I did over look the way a proximity sensor works. It does send out some type of signal and it needs to collect information such as reflection index and velocity to get an accurate measurement of distance
Didn't notice it lol.
Like britoso said:
It looks like infrared sensor. probally the proximity sensor.
HI GUYS
I'm really getting mad with my z1. I replaced my broken lcd and the serviceman used a lcd with lower build quality.
the lcd itself doesnt have any problem but the sensors go crazy and stop working after a while.
dont know what happens that they do so but mostly happens when i get a call or its on dock charger
the accelerometer, gyroscope, proximity sensor, ambient light, compass & etc. .they stop working and its very nerving thing
any way to fix this guys?! please help
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.
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.
Hello.
Im new to tasker, my problem is my proximity sensor is almost useless since the front glass is broken on the top of it.
Is there a way to read the ambient light values and trigger some functionalities. Such as AOD and lift to check. Using pixel 3xl btw.
