How to enroll for the Beta One Ui 4.0

[TheDean]

Hi.  I have Samsung Ultra 21 and would like to enroll in the Beta program to take advantage of some the new features. Specifically the Material theme.  How do I go about enrolling in this? Can someone provide a link?

Hello @TheDean ,

One UI Beta Program is unavailable for ATT devices. Only Sprint ,T-Mobile and Samsung unlocked device users would be able to register to the program.
