Samsung has just pushed the One UI beta based on Android 9.0 Pie in the US soon after it went live in South Korea. In the US, the beta program is available for T-Mobile and Sprint and to those using an unlocked Galaxy S9 or S9+.

It is unclear when other carriers in the USA would start the beta testing. To register for the beta, head over to the Samsung+ app and tap the notice that says “One UI with Android 9.0 on Galaxy S9/S9+. The update can then be downloaded by going into the Settings app, tapping Software update, then hit the Download updates manually option.
Apart from the One UI visual changes, there are many other changes and new features. Some of the new features include new adaptive themes for the keyboard that change based on the app you’re currently using, charging information in Always On Display, Scene Optimizer for the Camera app, and the ability to run DeX with a USB Type-C to HDMI cable while also being able to use the phone when DeX mode is active. It also brings November security patch update.
The update is around 2GB in size and since it is beta testing, there will be bugs and if you wish to roll back to Oreo, data wipe will be required, so it is best if you back up data before proceeding.
