Its been 20th december and my note 20 ultra is still stuck with the October 2020 security update. I tried to check the update manually but still it tells me that my phone is up to date with software.
While my mother's S9 got the dec 2020 security update already and most of the other samsung are already on december security update.
You're not alone, mine is the same as, still stuck with the October security update. And I doubt there's anything wrong with your phone as I just bought this phone a week ago.
