Downgrading from Android 11 back to 10?

[SEVEN_VEINS]

Is it possible to downgrade from One UI 3.1 Core based on android 11 to One UI 2.5 based on android 10? As smartview doesn't support chromecast anymore or should I wait for further updates from Samsung?

No bro its not possible becoz your bootloader was also updated with android 11 update and if you tried to downgrade then you might lose your device also

Impossible

It is possible but your device will be unofficial and may prone to security threats
