Software update on Note 20 ultra

I m huge fan of samsung note devices but this time I feel that samsung forget there old flagship phone when new phones launch....I m using Note 20 ultra the software update is inconsistent and update which we are getting that to consist bugs....I have seen S22 ultra got back to back 3-4 update. But for note 20 ultra nothing.....that's why iphones the ways better than samsung they take care of each phone they launched....
