Proximity sensor not working

this is exactly what I’ve been going through, and Xiaomi wants me to believe that it’s a hardware defect, thousands of people are experiencing the same problem, but before I got it, this bug was only presented on WhatsApp, when using for phone calls the  bug was not presented, the proximity sensor responded normally, only in WhatsApp that the sensor did not respond, but now with Android 10 it stopped working completely, and worse, now the automatic brightness sensor of the screen does not work!

I've finally solved my issue.
1. flash custom recovery and mound persist partition
2. adb pull /persist/sensors/registry/registry/
3. make backup copy
{"":{"owner":"sns_stk 3x3x","near_threshold":{"type":"flt","ver":"3","da ta":"1169.000000"},"far_threshold":{"type":"flt"," ver":"3","data":"1067.000000"},"ctir_calibration": {"type":"flt","ver":"3","data":"578.000000"}}}

in my case last value is less than first two so I've changed it to 2578
5. adb push /persist/sensors/registry/registry/

Since last ten days, I´m also having some problems with my phone, the screen turns black when calling or reproducing whatsapp sounds. Apparently is because of the proximity sensor. I have downloaded some programs and the sensor works ok. On the other hand some functions in my phone are not available like some features in the alarm clock. Are we expecting solve patch to some this problem?

Since ten days, the screen of my Mi A3 turns black when reproducing phone calls or whatsapp sounds. Apparently is because of the proximity sensor failure. But in my case, I have downloaded some apps to verify the correct work of this sensor, and I can tell that works ok. So should be some kind of update in my phone software because there are some others features that don´t work like reproducing news in the alarm clock. Are we expecting some patch to solve this probem ?
