RN7 lavender with 9.8.9 rom
After the update, proximity sensor no more working. Using hidden menu, the test fails (no way to run calibration or test)
I've been able to use again sensor, installing "Proximity sensor test" from Play store. Running "Fix" option, the phone require ti reboot....and after the sensor works againg
Also hidden menu works again, and i can again run calibration

I am also having problems with the sensor. I can solve using calibration apps but it won't work again when I restart the phone. Applications like Cpu Z or Aida64 do not recognize that the device has a proximity sensor. I use Redmi Note 7 too!

Sorry my bad english

Redmi Note 9.
I am having the same problem here.
I tried the calibration from the CTI but it didn't help. The sensor broke after 1 week of phone usage... I can't believe the phone are so fragile... I'll never buy again a Xiaomi phone.
