The March security patch is hitting more Samsung devices in the US — here's which phones have it so far - Android

  T-Mobile Galaxy S9

Samsung started updating some of its international devices to the March security patch last week, and now distribution is reaching unlocked devices in the US. As well as improvements to security, the update includes One UI 3.1, bringing with it a plethora of new features from the Galaxy S21 series to older phones.

One UI 3.1 rolled out to carrier models of the S20 last month, so it's nice to see it arrive for the unlocked Galaxy S20 as well.
