Samsung Extends One UI 9 Beta to Older Foldable Phones

What is One UI 9 and why it matters

One UI 9 is Samsung's latest Android skin, built on Android 13. It introduces a cleaner visual language, refined multitasking tools and deeper integration with Samsung's ecosystem. For foldable devices, the update promises smoother transitions between screen states, improved app continuity and more efficient power management. Early adopters have praised the refreshed notification panel and the new Edge Panel shortcuts that adapt to the larger display.

Key improvements over One UI 8

Unified design language that reduces visual clutter.
Enhanced split‑screen experience with dynamic resizing.
Native support for Task Continuity across the cover and main screens.
Battery optimisation that leverages AI‑driven usage patterns.
Updated privacy controls that give users granular permission settings.

Older foldables now eligible for the beta

Samsung announced that the One UI 9 beta will no longer be limited to the latest flagship foldables. Owners of earlier models can now enroll, extending the testing window and gathering feedback from a broader user base. The move reflects Samsung's commitment to keeping its entire foldable lineup up to date, even as newer devices hit the market.

Which models are included

Galaxy Z Fold3 5G
Galaxy Z Fold4
Galaxy Z Flip3 5G
Galaxy Z Flip4

How users can enroll

Open the Settings app on the device.
Navigate to Software update > Beta program.
Select One UI 9 beta and follow the on‑screen prompts.
Confirm the download and allow the device to reboot.
After installation, explore the new features and provide feedback through the Samsung Newsroom portal.

Impact on performance and user experience

Early reports from beta participants indicate noticeable gains in responsiveness, especially when switching between apps on the unfolded screen. The revised animation engine reduces lag, while the updated power scheduler extends screen‑on time without sacrificing battery life.

Battery optimisation

One UI 9 introduces a context‑aware power mode that learns user habits. When the device detects that the cover screen is active, it throttles background processes to preserve energy. Conversely, during intensive tasks such as gaming or video editing, the system allocates more resources to maintain performance.

Software features

Redesigned Quick Settings with larger toggles for easier access.
Improved Samsung DeX integration that supports external monitors at higher resolutions.
New Secure Folder enhancements that encrypt data with hardware‑level keys.
Enhanced Camera UI that adapts to the foldable form factor, offering seamless mode switching.
Support for Android 13 developer notes that enable richer widget experiences.

Developer and ecosystem implications

Opening the beta to older hardware provides developers with a wider testing ground. Apps that rely on foldable‑specific APIs can now be validated across multiple generations, reducing fragmentation. Samsung's Support portal offers detailed guidelines for adapting UI elements to the new layout rules.

App compatibility

Developers are encouraged to use the WindowManager APIs that report real‑time screen dimensions. This ensures that content scales correctly whether the device is folded, partially opened or fully expanded. The beta also includes updated emulators that mimic the behavior of legacy foldables, streamlining the testing process.

Future updates

Samsung has hinted that the feedback collected from this expanded beta will shape the final One UI 9 release for all foldables. Features such as adaptive refresh rates and advanced multi‑window gestures are expected to roll out later in the year, aligning older models with the capabilities of the newest devices.

How to stay updated

Users who have enrolled in the beta should keep an eye on official channels for patch notes and known issues. Samsung typically publishes release information on its Newsroom and within the Community forums. Following reputable tech sites such as GSMArena can also provide timely insights into performance trends and user experiences.

By extending the One UI 9 beta to older foldables, Samsung not only enhances the value of its existing devices but also strengthens the overall foldable ecosystem. The move signals a long‑term commitment to software excellence, ensuring that users enjoy a consistent and future‑ready experience across the entire Galaxy Fold and Flip families.
