I'll give an example. My hubby's step-father has an unlocked S21, and has *no* idea that an "Android 12 UI 4" exists, so doesn't know he should get it 😁
Hello @scarface1958 ,
All Unlocked devices should be able to receive One UI 4 update at this time. Update was opened for carriers in two separate rounds based on CSC which may have caused some of users to receive an update before others.
Please call us at 1-800-726-7864 if you are still unable to update to One UI 4.
