Samsung's Android 10-based One UI 2.0 beta is near completion for the Galaxy S10, which received its third batch of software a few days ago. Galaxy Note 10 users, however, have had to wait a considerable amount of time for their taste of Android 10. Although the beta has opened up in some markets, it is not as widely available as the Galaxy S10. Today, Samsung just announced that Galaxy Note 10 users in the US can now participate in the One UI 2.0 beta program.
