I hope that this will really improve the situation.
I really thought I was the only one with this problem and my phone is broken, but it seems like almost everyone has this really annoying problem.

Until the patch is out and has really improved the proximity sensor performance, I wouldn't recommend this phone!
It's just too basic to be not working correctly (I accidentally ended multiple calls e. G.).

Quick TuneUp (apk)

Use this app to fix the problem of the call sensor (hear audio), simple and easy, install the app and go into sensor calibration and let it calibrate and restart your phone!
Daaaaaamn. This fixed mine also... At least for the moment. Great tool..interesting what has it done since my phone's not rooted :)

Thanks a lot !

Le: spoke too quickly... Nothing is solved... Problem is back... I'm having 1 week left till I can return to vendor the phone.
Love the phone
Hate the bug !!!!! :(((

Thinking of returning it...

I have Poco f3 and it have what's App playing audio black screen problem .
I just found phone doesn't have proximity sensor at all and use ultrasonic instead.
I cii calibrating and it doesn't work! But I think problem is something else
If you hold phone tall standing and playing audio file screen goes black and audio play through ear speaker but if you lay down phone flat and play audio it's just work fine. Maybe accelerometer problem!?
Anyway it's temporary fix until Xiaomi fix the problem
Any new update from Xiaomi!?

With China weekly firmware version 21.8.4 the sensor works perfectly for me. However with this firmware the light sensor doesn't work so I can't use automatic brightness. I'm on Arrow ROM. Hopefully this means with a future update it will work well for everyone.

    Before buying the Poco F3 I've never had a phone with this system without a proximity sensor, and the truth is that after using the phone for two weeks I'm sick of it. I'm even thinking of selling the phone.

    Due to the fact that the problem is related to the lack of appropriate hardware, I think that a possible solution for phone calls could be that the screen would automatically lock when answering calls, and then to manipulate the screen again it would be necessary to unlock a via a slider, pattern, fingerprint, or facial recognition.

    Do you know any solution or calling app that allows to do something about this? Root wouldn't be a problem.

    Thank you.

    Xiaomi Redmi Note 10 Pro, Poco X3 NFC, & Poco F3 proximity sensor issues to be fixed with future updates.​

    so is the proximity sensor actually broken on everyones device. what the hell something as simple as that they messed up.
    As far I know, this phone don't have any proximity sensor, I guess that this is because design reasons, don't think that the proximity sensor hardware cost more thant cents. The phone uses an ultrasonic "sensor" combined with the gyroscope, because of that, the sensor only works (when it works) with the phone in vertical.

    For Whatsapp, instagram or other audios I don't think there is a solution for this, even with future updates, since the main problem is the lack of hardware and isn't possible to modify the apps.

    I thought that a "solution" for phone calls could be that if when answering calls the touchscreen locks automatically (even if the sensor malfunctions and don't turn off the screen), and for unlock a slider on screen or something similar was necessary, could be a solution for misstouching the touchscreen with the face. Even using screensaver mode/blackscreen for this purpose could be a solution, but I can't figure out if this is possible with some other third party telephone app.
