Days after kicking off the One UI 8 Beta, Samsung closed new enrollment in the US. The Beta Program devices are the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra. The Program is available in Germany, Korea, the United Kingdom, and the United States.

Two days ago, Samsung confirmed that both the Galaxy Z Flip7 and Galaxy Z Fold7 will come with stable One UI 8. This means that users of these Galaxy foldable devices will enjoy all the new features right out of the box. After that, Samsung will gradually release the update for more Galaxy phones and end the beta program.

Samsung One UI 8 Beta closed

AdamJMatlock on X noticed that the new One UI 8 beta enrollment for the Galaxy S25, S25+, and S25 Ultra has closed in the US. This means that the Samsung Members app is no longer accepting new registrations and is informing users that the beta program has reached its capacity. Now, you have to wait for the program to reopen to register.

In addition, Samsung Members is the key to unlock the One UI 8 beta program. The beta program banner is shown on the home page of the app. Clicking on the beta banner takes you to a short process to finish the registration.

Just like One UI 7 beta registrations, One UI 8 beta registrations crossed the line within a few days of the program’s official launch. This is not surprising news, as Galaxy fans have been eagerly waiting for the Android 16 beta software ever since the stable version rollout for Pixel devices.

Until then, you have no official opportunity to get the latest update on your Galaxy S25 series. Manually flashing the OTA is a solution to get it right away. However, we don’t suggest doing this on your primary Galaxy device as it may cause data loss.

As you know, Samsung’s Android 15-based One UI 7 offered the predictive back feature only in Google applications and not in stock apps on Galaxy phones and tablets. Samsung’s Android 16-based One UI 8 for Galaxy phones and tablets expands the predictive back feature to Samsung’s stock apps, according to a report.

On the other hand, Samsung fans are excited about the next big software update for the Galaxy device. One UI 8 beta has officially launched, with the Korean tech giant confirming the program and releasing the first beta update.

After installing and digging, Android Authority has found that on the Galaxy S25 with One UI 8 beta, Predictive Back also works in some of Samsung’s stock apps, including:

• Clock
• Calculator
• Weather
• Settings
• Voice Recorder
• Contacts

Unfortunately, Android 15 predictive back doesn’t work in some other stock apps, including Calendar and Reminders.

With One UI 8, you can see that there is now a toggle for Predictive back animation visible in the Developer Options menu. Notably, this setting can be found via the Settings search bar in One UI 7, but won’t show up when tapped, almost like it’s hidden.

Which devices currently support One UI 8 beta?

Samsung has officially confirmed the eligible devices and countries:

One UI 8 eligible devices:

• Galaxy S25
• Galaxy S25 Plus
• Galaxy S25 Ultra

One UI 8 eligible countries:

• United States (T-Mobile locked and unlocked devices)

Earlier reports suggested that the Samsung Galaxy Z Fold 7 and Galaxy Z Flip 7 would come with One UI 8 (Android 16). Now, just months ahead of its big Galaxy Unpacked launch event, Samsung is saying that One UI 8 will debut on Samsung’s newest foldable this summer.

According to the Samsung Newsroom, One UI 8 will debut on Samsung’s latest Galaxy Z Fold 7 and Galaxy Z Flip 7 foldables this summer and will gradually expand to more Galaxy devices so users can now enjoy a richer, more personalized mobile experience with the latest version of Android.

Samsung says: “Thanks to the mutual partnership between Samsung and Google, One UI 8 will debut on Samsung’s newest foldables this summer and will gradually expand to more Galaxy devices so users can now enjoy an enriched, more personalized mobile experience with the latest version of Android.”

Samsung officially released the beta version of One UI 8 on May 28, 2025 (today), marking the end of a rather long anticipatory period since Android 16’s official launch. This is when the One UI 8 beta program began for the Galaxy S25 series.

Samsung started the One UI 8 rollout for devices with a beta program. So yes, the One UI 8 beta has started with the Galaxy S25 series. All devices that are expected to get One UI 8 stable are also expected to get a beta program before that, which will help polish and finalize the update for that device. So keep an eye on the beta program for your device in anticipation of the stable update.
