After introducing its brand new One UI earlier this month, Samsung has begun seeding the update to beta testers.

Samsung today launched its Android Pie beta program, letting Galaxy S9 and S9+ owners get an early taste of Samsung's next major Android OS update. The program is currently live in South Korea and the U.S., too. You can sign up for the beta in the Samsung Members app, or for those folks in the U.S, the Samsung+ app.

The One UI is a big update for Samsung, offering a refreshed UI that aims to make using big phones easier with one hand. Samsung has done this by keeping most of the content that you interact with in the bottom half of the screen and keeping the stuff you want to view in the upper half. For example, the Messages app keeps your list of conversations in the bottom half of the display.

Also included in the One UI is an updated look. Samsung says that it worked to make One UI more clear and intuitive and to tune the colors to give them more visual clarity. Samsung is adding a Night Mode across its One UI, too, which can help save battery life on devices with OLED screens.

Samsung has said that it plans to begin deploying One UI to the Galaxy S9, S9+, and Note 9 in January 2019.
