Galaxy Z Fold4 One UI 8 Build Spotted: Beta Testing Imminent

Samsung Galaxy Z Fold4 and Z Flip4 have been spotted testing the upcoming major update! A new Galaxy Z Fold4 One UI 8 appeared on internal servers. This exciting leak is a very good sign that beta testing for Android 16 is just around the corner for these best-selling 2022 foldables. It suggests that Samsung is prioritizing them for the new software experience.

This server sighting is big news for Z Fold4 and Z Flip4 users. It validates that Samsung is indeed developing and testing Android 16 for these devices ahead of a public beta release. This internal testing process is usually reserved first for the latest flagships such as the S25 series. To see builds for the relatively older Fold4 and Flip4 this early is a sign of a rapid update journey. The build structure itself also suggests optimizations made specifically for foldable aspects such as the special multitasking and Flex Mode features.

What New Features to Anticipate with One UI 8

According to early beta feedback from other devices, the Galaxy Z Fold4 One UI 8 update has a lot to provide. The users can presumably expect:

Alert Center: Instant alerts when apps use your camera, microphone, or location in the background, for this reason enhancing privacy awareness.
Enhanced Now Bar: View live, glanceable notifications from all your apps (like Uber, WhatsApp, or Calendar) on the lock screen to access information quicker.
Audio Eraser Pro: Using the power of next-gen AI to eliminate unwanted background noise (wind, background chatter) from your videos and voice recordings instantly.
Refined Multitasking: Smoother app switching and perhaps an overhauled Taskbar, further pushing the Fold4’s desktop-like experience to be even more intuitive and capable.

When Can Z Fold4 & Z Flip4 Owners Expect the Update?

While Samsung has not made any official date announcements, the trend of leaks and previous rollouts gives us a clue. The stable Galaxy Z Fold4 One UI 8 release likely follows this order:

Late July 2025: One UI 8 stable arriving on Galaxy S25 series.
Aug-Sep 2025: Z Fold4, Z Flip4 public beta program available to enthusiasts to try out before release.
October-November 2025: Stable One UI 8 rollout begins for Fold4 and Flip4 globally.

Though there can be some delays (like with some of the budget phones the One UI 7 release coming later), foldables are the priority for Samsung, so this schedule is feasible.

This early Galaxy Z Fold4 One UI 8 build leak underscores Samsung’s commitment to its foldable user base. It shows they’re not just supporting the latest models but actively bringing cutting-edge software to devices like the Fold4 and Flip4 relatively quickly. This focus ensures foldable users get the unique optimizations their innovative form factors demand, potentially even ahead of some newer mid-range phones.

This server leak is concrete evidence: the Galaxy Z Fold4 One UI 8 update is actively in development and approaching beta testing. Samsung is clearly pushing to deliver Android 16 and its exciting new features to its 2022 foldable flagships within the coming months. For Fold4 and Flip4 owners, a significantly enhanced software experience is on the horizon.
