Galaxy Z Flip 5 One UI 8 Beta: Development Progress, Rollout Plans, and Features

Samsung continues to refine its custom Android skin, One UI 8, which is based on Android 16. The company has already started deploying beta builds for several of its flagship devices and is gradually extending support to slightly older models. Among these is the Galaxy Z Flip 5, a foldable device released in 2023. Recent reports indicate that Samsung is actively working on the beta for this model, with signs of progress visible on its servers.

New Beta Build for Galaxy Z Flip 5

A new firmware build for the Galaxy Z Flip 5, version F731NKSU5ZYHC, was recently spotted on Samsung’s servers. This version is tied to the One UI 8 beta and was compiled in August 2025. The discovery highlights Samsung’s ongoing work on ensuring the foldable device is optimized to handle Android 16’s latest features alongside the company’s custom enhancements.

This progress follows Samsung’s earlier confirmation that the Galaxy Z Flip 5 would be included in the list of devices receiving the One UI 8 beta. The detection of this build suggests that the internal testing phase is advancing steadily, bringing the update closer to public release.

Expansion of the One UI 8 Beta Program

The One UI 8 beta program launched earlier this year with Samsung’s newest flagships, beginning with the Galaxy S25 series. In the weeks that followed, it was expanded to include the Galaxy S24 series, Galaxy Z Fold 6, and Galaxy Z Flip 6 in selected markets such as South Korea, the United States, India, and parts of Europe.

Now, Samsung is preparing to expand access even further. The next wave of eligible devices includes the Galaxy Z Flip 5, Galaxy Z Fold 5, Galaxy S23 series, and mid-range models such as the Galaxy A55 and Galaxy A36. Users of these devices should see the beta program open in early September 2025 through the Samsung Members app.
