Samsung Begins One UI 9 Testing: New Features and Device Compatibility for Android 17

Samsung has begun internal testing for One UI 9, a new user interface based on Android 17, across 18 different Galaxy devices according to reporting from Alahdonline. The development process includes early tests of One UI 9.5 specifically for the upcoming Galaxy S26 series, as reported by Alam Al-Taqnia.

The testing phase targets a broad range of hardware, including the future Galaxy S26, Galaxy Z Fold 8, and Galaxy Z Flip 8. Alahdonline reports that current-generation hardware, such as the Galaxy S25 series and Galaxy Tab S10 tablets, are also included in the laboratory checks to ensure the Android 17 core integrates with Samsung’s proprietary interface.

Galaxy AI and Visual Interface Updates in One UI 9

The upcoming update focuses on expanding generative artificial intelligence capabilities through an evolved Galaxy AI platform, according to Alahdonline. These software changes aim to deepen the integration of AI across the operating system’s functional and visual layers.

Visual modifications include a comprehensive redesign of interactive animations to improve responsiveness on high-refresh-rate screens. Alahdonline further reports that Samsung is testing an interactive floating bubble system and a redesigned taskbar specifically for foldable devices.

Underlying system improvements involve new machine learning algorithms designed to optimize battery power consumption and enhance data security, Alahdonline reports.

Deployment Timeline and Device Eligibility

Samsung is shifting its traditional development schedule to accelerate the release.

While the S26 series is a primary focus for One UI 9.5, other devices have specific support trajectories. 25h.app reports that the Galaxy S23 FE will receive Android 17 and One UI 9 as its final major OS update. Additionally, Sada El Balad reports that Samsung has released a list of eligible Galaxy Watches that will qualify for the One UI 9 update.

Comparison of Testing Scope

The current testing phase differs from previous cycles by its horizontal reach. While early tests typically focus on a single flagship line, Alahdonline notes that the current 18-device list spans both premium and mid-range Galaxy families simultaneously. This approach is intended to reduce technical errors before the software reaches the general public.

Samsung Magazine reports that the company continued delivering updates to various devices during week 32 of the year, maintaining current support while simultaneously preparing the Android 17 transition.
