Samsung is continuing its update hot streak this week, starting the US rollout of the January 2021 security patch with the unlocked Galaxy S20 and Note20, as well as the Verizon S10 5G and A50. The changelog doesn't mention anything other than the bump to January's patch, so don't expect any new features.
A bunch of Galaxy phone users got a bit of a head start on the December 2020 security patch when Samsung released the update two weeks ahead of schedule. While that update was meant for some international beta users testing out One UI 3.0, Samsung kick-started the stable rollout of the latest patch in the US at the beginning of the month. The first device to get bumped to the December 2020 level was Verizon’s Galaxy S20 FE, most recently followed by T-Mobile's Galaxy S20 and S10 series, along with the Tab S6 Lite.
