Proximity sensor emits IR always - Samsung Galaxy S9 Questions & Answers

I recently find out that my S9 keep emitting IR from the proximity sensor, is that normal or it's something not right happening on my phone.
P/s: I did some Google and found out that S9 has 2 proximity sensors, but why it has to be two of them but not one like other phones?
Also the IR led on the video below can only be seen via a surveillance camera, not via other phone's camera.
Please see my video

I have CCTV on my house and at night when people walk past using their phone you can see the same thing, probably for the "Block accidental touches in a dark place", as the screen off when making a call 'should' only activate the IR when you are on a call
Also if you are playing a voice message on WhatsApp and put your hand too close the to proximity sensor it stops the playback
Phone camera as an IR block filter to filter out IR, although you can still see TV Remotes IR with it

Thank you for your comment, but event when I turn that function off, the IR still blinking.
I know I may just being over-thinking but it's bugging me still.
Even though I could not see it blinks but I still know it's blinking always without any explanation.

Easy screen turn on
I finally know the reason why.
It's the "Easy screen turn on" feature that keep the proximity sensor emitting IR.
Once turn it off, the sensor no longer emits IR.

Problem when answer a call via Bluetooth hand set!!!

Problem when answer a call via Bluetooth hand set!!!
When answering a phone call with a Bluetooth hand set and the device is in the case the screen remains on during the call, only if I take the device out and than back into the case the screen goes off. The light sensor turns the screen off only if it senses a light and than dark.
Is it possible to do something that when answering a phone call with Bluetooth hand set the screen will turn off (or not turns on at all) automatically to save battery power?
Thanks,

Noise from camera

Maybe someone has had a similar problem.
Sometimes when particular app opens camera and the camera sensor is active the sensor will buzz. It is happening only in 1 app.
Second is that when i shake the phone I hear a rumble near the camera. When the camera is turned on, it is less rumble when shaking the phone.
Otherwise I think the camera is working ok. Zoom is ok, when i cover with my hand the sensor there is no buzz.
Someone had a similar situation?
My Mi5s just started to do exactly the same when I start the camera app. Any solution to this noise?
The exact same thing happened to me, until the camera stopped focusing and I had to change it

S20. Disable proximity sensor while using whatsapp

Hello to all. I read on the net that it is a common problem. when we listen to a voice message on whatsapp, if we make the mistake of bringing the phone to the ear, activating the proximity sensor, the audio stops. is there a way to make whatsapp play audio messages exclusively in speakerphone without activating the proximity sensor which obviously does not work correctly? thanks

Disable proximity sensor

I have not luck with an aliexpress screen replacement, the screen has not the holes for light sensor an proximity sensor. So the light sensor is not problem, i can manual adjust the bright level, the real problem is the proximity sensor, i need to disable because when i receive a call the screen is enable and earphone speaker is disable, so the only method to manage a call is with hands free.
Any idea???

Question Whatsapp proximity sensor voice note not working

Hi All
Have a stock rom Fold3 and having an issue whereby the proximity sensor is not turning off the screen in WhatsApp when you bring the phone to your face to listen to a voice note, so you just get blasted in the ear by the speaker instead of it switching to the earpiece
Thanks in advance all
I have exactly the same issue. it blasts the sound from the speaker for a second then turns it to the earphone. There's a delay

For the moment i'm using this fix:
On smartphone go to Bluetooth connected smartwatch settings and turn off for calls. (not using my watch for call anyways)
Same issue on my Note 20 ultra connected to my GW4!
Hi, I have the same issue using S21 Ultra + Watch4 and fixed disabling Calls on BT settings of the watch as suggested. Any news regarding a real fix from Samsung?
I have the same issue on Zenfone 8 with GW4, and whatsapp version 2.22.18.75.
Is there any news about this issue?
I have an update on this, in my case, the issue is not limited to the smartwatch, but to every Bluetooth device for which the calls are enabled, I tried with my car's Bluetooth and a pair of earphones.
Can someone else test with earphones as well? I disabled multimedia audio and left enabled calls, and the proximity sensor with whatsapp doesn't work
Same problem for me with a Samsung galaxy a71 and a watch 4 classic
I guess we have to wait for a fix from whatsapp...

This issue may occur because your proximity sensor is turned off. You can turn it on by going to your phone's settings. You can turn it on from call settings or turn it on from sensor settings.

the proximity sensor is turned on, in fact, it does work with other applications like telegram.
The issue is only with WhatsApp and only if a Bluetooth device, with the call option enabled, is connected.

you don't need to disconnect the watch completely, it is enough to disable the call option in the Bluetooth connection settings of the watch, leaving it connected
With WhatsApp version 2.22.21.83 the issue seems to be solved!
If the proximity sensor on your device is not working properly while using WhatsApp voice notes, you may want to try the following solutions:
Clean the proximity sensor: Sometimes, dirt or dust may accumulate on the proximity sensor, which can cause it to malfunction. Clean the sensor using a soft cloth or cotton swab.
Restart your device: Restarting your device can often solve minor software issues that may be causing the proximity sensor to malfunction.
Update WhatsApp: Make sure that you are using the latest version of WhatsApp. Check the app store for any available updates and install them if necessary.
Check permissions: Make sure that WhatsApp has permission to access your device's microphone and proximity sensor. You can check this in your device's settings.
Disable screen protectors or cases: Screen protectors or cases may interfere with the proximity sensor's ability to detect when your device is close to your ear. Try removing any screen protectors or cases and see if that resolves the issue.
If the problem persists, you may want to contact the manufacturer of your device or WhatsApp support for further assistance.
when you bring the phone to your face to listen to a voice note on WhatsApp, the proximity sensor fails to turn off the screen. As a result, instead of the audio playing through the earpiece, it blasts directly through the speaker, causing discomfort in your ear.
Hi friend
If the proximity sensor is not functioning properly while using voice notes on WhatsApp, try restarting your device or reinstalling the app. If the issue persists, consider reaching out to WhatsApp support for further assistance.Free Fire
