As I posted in the other thread, I just got an update this morning. Up until today, checking always told me my phone was up to date. Today's update however is one for January that was released on 2/09/2022. I am surprised this did not appear available for my S22 Ultra until today.
Sounds like T-Mobile unlocked is the only U.S. phones to have the March update as of this morning. Anyone who gets the unlocked update from another provider please chime in.
