I have already updated my Redmi K20 Pro to this version  and facing Proximity sensor issues. Proximity sensor is not at all working. Anybody facing this bug?

I have tried the "Incoming Call Setting" solution and rebooted the phone but it is not working. I have also tried the "Service Menu" (tapping Kernel Version 5 times) and there also the sensor is not working. There is no option for calibration either.

Please suggest what should I do? Will I be waiting for the next update?
