Update, November 9, 2018 (11:20AM EST): To clarify, the One UI beta is not officially available yet. Samsung published the steps to sign up for the beta on its website, but the One UI beta is not yet available for the Galaxy S9, S9 Plus, and Note 9. It will arrive sometime this month.
Also, we are unsure if the steps to sign up for the One UI beta with the Samsung Members app are the same with the Samsung+ app. Finally, folks in the U.S. can only sign up for the beta through the Samsung+ app. There is no Samsung Members app officially available in the U.S. through either Galaxy Apps or the Play Store.
We updated the article below to reflect these changes and I personally apologize for accidentally misleading you into thinking that the One UI beta is available right now.
Updated article: Fresh off its announcement of its revamped One UI software design, Samsung also announced the One UI beta program. So long as the excessive use of rounded corners does not bother you, signing up for the One UI beta program is extremely easy.
Before we go over the steps, keep in mind that the One UI beta is not officially available yet. Even though Samsung published the steps to sign up for the beta, no one has officially received the beta or been able to sign up for it yet.
You must first download the Samsung Members app from either Galaxy Apps or the Play Store. Once you log in, go to Notices and select One UI Beta Program Registration to submit your application. If you are selected, go to Settings and then Update Software to pick the Download Updates Manually option. From there, just sit back and wait until the One UI beta version downloads and installs on your device.
There are a few things to keep in mind, the first being that U.S. residents will be able to sign up through the Samsung+ app. We are unsure if the steps are the same with the Samsung+ app. You must also have a Samsung account if you want to participate in the One UI beta program.
Finally, the One UI beta will first roll out to Galaxy S9, Galaxy S9 Plus, and Galaxy Note 9 owners this month in the U.S., Germany, Korea, China, France, India, Poland, Spain, and the U.K. The beta will also roll out to additional countries in Europe and Asia in the future.
Announced during today’s Samsung Developer Conference in San Francisco, One UI focuses on three UI aspects: simplification, ease of use, and making everything more visually appealing. Several built-in Samsung apps feature a viewing area up top and an interactive area at the bottom. Multiple Samsung apps also feature a bottom navigation bar in an effort to streamline the user experience and make one-handed use that much easier.
We can go on, but you can download the Samsung Members and Samsung+ apps at the link below to apply for the One UI beta program and see for yourself.
