Galaxy S20 FE 5G / Android 12 / Auto Brightness, "BrightnessBNR" system application drains battery

After upgrade to Android 12, adaptive brightness feature drains battery.

I observed frequency of CPU cores jumping to max levels systematically, approx. every 3 sec. (in CPU-Z) when auto-brightness is ON, and current consumption jumping to 700 mA as well, when adaptive brightness is ON.

When OFF, CPU works stable in very low-medium level frequency levels.

When ON, again: jumping of frequency (and current consumption) to very high level.

And it is reflected in "BrightnessBNR" hidden details (shows 10% battery consumption in system application details).

Clearing partition cache and application "BrightnessBNR", "camera sensor" cache/data did not solve the issue.

PS. Second phone, with old Android 11, works fine and stable.

What type of reset do you mean? I have already restarted my phone several times...
