Hey there
At release in 2020 Samsung announced the Note 20 Series would get 3 years of updates (this was more groundbreaking then usual for Samsung as 2 years was the norm back then).
Android 13 OneUI5.1 was the last OS update.
You may get one or two security patches but otherwise that's about it now as Samsung effectively killed off the (rather brilliant) Note Series in favour of S Series Ultra models that came with SPen.
S24 Ultra
