Unstable promissory sensor

[demonntl]

Hi friends,
I got my K20P for 6 months with latest EU rom. Recently i notice that the promissory sensor is hit and miss sometime, the brightness bar adjustment will only take effect after the screen is off and on again. .
I also notice that reboot 2 times in a row solve the problem, until the next reboot.
Does anyone have the same problem and fond solution ?
Thanks.

By the time passed from your post and the lack of responses I guess that's not spread issue.
I am personally not experiencing any issue with the proximity sensor.
What is the xiaomi test/testing showing?

The test is pass, i dont think it a hardware problem because 2 reboot will help.
I try to reflash the EU rom but cannot solve the problem. I did not try full wipe but will try when have time to.
