Proximity sensor issue

[Guciu]

Model Name: Asus Zenfone 9 8/128GB
Firmware Version: 30.2040.2040.23
Rooted or not: Not
Frequency of Occurrence: All the time, during a call or in pocket safe mode
APP Name & APP Version (If your issue relates to the app): N/A

I noticed that proximity sensor is not working correctly. Is it only my case and I should complain my product?
It is working for maybe 5mm. All my previous phone turned on the screen when distance between phone and my face/ear is longer than couple of centimeters, let's say 5cm. Asus Zenfone 9 makes it longer than 5mm I have the feeling. It is extremely close. I need to really stick phone to my face to avoid turning on the screen.
Most probably issue is the same with pocket safe function. If it is turned on I assume proximity sensor should recognize it is in the pocket and doesn't turn on the screen. However again, screen is turning on and most probably reason is the same. It allows screen to turn on if distance is still very close, couple of milimeters which in jacket i.e. is highly probable.
Please let me know if this is a matter of proximity sensor settings (and I hope it will be fixed) or it is my piece issue and I need to complain.

I was able to find, but only about Zenfone 8 (newest). I have not seen the same topic for Zenfone 9.
Additionally, I have identified next related issue. Instead of pocket mode enabled and sticking proximity sensor, it is still possible to unblock phone in the pocket by fingerprint sensor.
In my opinion it should be blocked. You can always press fingerprint sensor by mistake in the pocket and phone is not recognizing correctly it is in the pocket.

OK see that topic. But advice there is to switch fingerprint sensor to the mode when you need physically press button to unlock. That is not convinent.
What is then function of "pocket mode", so function which prevent screen to be ON in the pocket?
This function doesn't work correctly. Whenever pocket display ON prevention feature is ON, phone should check if it is IN THE POCKET before turning on the screen. It is not.
I am refering to function in SETTINGS/ADVANCED SETTINGS/ pocket mode (or whatever english name of this function is).
