One UI 3.0 is Samsung’s latest customized build of Android based on Android 11. A public beta build of One UI 3.0 had previously been available for the Samsung Galaxy S20, Galaxy S20+, and the Galaxy S20 Ultra in the United States and South Korea, but the OEM is gradually expanding the beta initiative in more regions across the globe. The Exynos powered international variant of the Galaxy S20 has now received its first One UI 3.0 beta update in Europe.
This update is currently rolling out to users in Germany, i.e. for the Exynos 990 laden carrier unlocked Galaxy S20 lineup. The initial beta build with version G98xxXXU5ZTJA comes in at about 1.8GB in size. The update brings in all of the new features included in the stable Android 11 codebase to these phones, along with several improvements to Samsung’s own One UI skin. Additionally, the U.S. Snapdragon model of the Galaxy S20 has received a similar build with version number G98xU1UEU1ZTJA as its second One UI 3.0 public beta firmware. In both cases, Samsung bumps up the Android security patch level of the device to October 2020.
For those of you who want to take this software release for a spin, you can download the appropriate OTA package for your model from this index and sideload it using the stock recovery environment. While you do get the opportunity to try out the latest firmware release from Samsung, with its revamped UI and host of new features, before it is rolled out to the public, keep in mind that this comes with the risk of system instability and broken features. Fortunately, Samsung has yet to increment the bootloader version in these beta builds, which means you can still revert back to stable Android 10/One UI 2.5 firmware by performing a manual flash.
