Hi @Buddyfan yes @Pugs1957 is correct. If purchasing now would be on Android 10 (though I notice it is not currently available via the Samsung store in Uk,either direct or via partners) The stable Android 11 will start to be released on the S20 in December, likely to receive the firmware on the S10 range early next year.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
One Ui 5.0,Android 13 .
