Dude now u have only 2 options either u need to change ur phone to new one or else adjust and use the current phone because Samsung won't even touch the old phones regarding the software updates
Ha bhai better swap with a new phone and don't go ryt now wait for the phone which comes with android 13 as builtin so u will get atleast another 2 year if it's low budget 3 years mud budget or 4 years for good budget phones
