Samsung Expands One UI 9 Beta Testing to More Galaxy Devices Ahead of Launch


Samsung is picking up the pace with One UI 9 development. After rolling out One UI 8.5 across multiple Galaxy devices, the company is now testing its next major software update on an even wider range of smartphones.

Recent firmware discoveries suggest Samsung is preparing One UI 9 for flagship, foldable, and mid-range devices before its official debut at Galaxy Unpacked later this month.

One UI 9 Testing Reaches More Galaxy Phones

According to firmware tracker Tarun Vats, Samsung has started internal One UI 9 testing for several additional devices.

The latest phones reportedly receiving internal builds include:

  • Galaxy S23 FE

  • Galaxy M34

  • Galaxy Z Fold 6

  • Galaxy Z Flip 6

  • Galaxy A37

These join a growing list of devices already participating in One UI 9 development, including:

  • Galaxy S23 series

  • Galaxy S24 series

  • Galaxy S24 FE

  • Galaxy S25 series

  • Galaxy S26 series

  • Galaxy A35

  • Galaxy A56

  • Galaxy A57

This broad rollout shows Samsung is preparing the update across several product families simultaneously.

Samsung Focuses on Stability Before the Official Release

Unlike One UI 8.5, which introduced several visual and AI-driven changes, One UI 9 appears to prioritize refinement and overall performance.

Recent beta releases have focused on fixing software bugs, improving system responsiveness, and polishing existing features rather than introducing a completely redesigned interface.

Samsung has also maintained a steady beta release schedule, delivering multiple updates over the past few weeks to improve reliability before the public rollout.

Latest Beta Fixes Improve Everyday Performance

The newest beta versions address a wide range of issues reported by testers.

Among the improvements are:

  • Better camera preview performance

  • Improved zoom accuracy

  • More reliable weather and battery widgets

  • Fixes for S Pen gesture recognition

  • Smoother scrolling in My Files

  • Reduced unexpected system reboots

  • Stability improvements for incoming calls and notification panels

These updates indicate Samsung is entering the final stages of software optimization before launch.

Good Lock Is Ready for One UI 9

Samsung is also updating its popular Good Lock customization suite to support the upcoming software.

The latest version of LockStar now works with One UI 9, allowing users to continue customizing their lock screen, Always On Display, widgets, shortcuts, and layouts without compatibility issues.

As additional Good Lock modules receive updates, users should have access to the same level of personalization immediately after installing One UI 9.

Upgrading to a New Galaxy? Prepare Your Data First

Major software updates often inspire users to upgrade to a newer phone, especially when Samsung launches new flagship devices alongside One UI 9.

If you're moving to a new Galaxy smartphone, using a reliable data transfer app can make the transition much easier. Smart Transfer helps simplify phone to phone transfer, allowing you to move contacts, photos, videos, documents, and other important files without lengthy setup or complicated steps.

The app is also useful when you need to transfer data Android to Android. Whether you're upgrading from an older Galaxy device or switching from another Android brand, Smart Transfer helps keep your content organized so your new phone is ready to use much faster.

Accessibility and Security Receive Important Upgrades

Samsung continues expanding accessibility features in One UI 9.

One notable addition is an improved TalkBack experience that combines Samsung's accessibility tools with Google's screen reader functionality. Users can also benefit from Text Spotlight, a new floating zoom tool designed to make reading easier.

Security has also received attention. One UI 9 introduces smarter protection against potentially harmful applications by detecting suspicious apps before they are installed or launched.

AI Features Continue to Expand

One UI 9 builds on the AI enhancements introduced in One UI 8.5.

Previous updates added features such as AI-powered call screening, live voicemail transcription, enhanced Bixby capabilities, AI-generated wallpapers, and stronger privacy alerts.

Rather than replacing those tools, One UI 9 focuses on making them faster, more reliable, and better integrated into the overall Galaxy experience.

Which Samsung Phones Will Receive One UI 9?

Samsung is expected to officially unveil One UI 9 during Galaxy Unpacked alongside its newest foldable smartphones.

The Galaxy Z Fold 8 series will likely be the first devices to ship with the new software.

Following the launch, Samsung is expected to begin rolling out the stable update in phases:

  • Current flagship Galaxy S devices

  • Recent Galaxy Z Fold and Z Flip models

  • Fan Edition devices

  • Galaxy A series smartphones

  • Selected Galaxy M series devices

The rollout will likely continue over several months, following Samsung's typical update schedule.

Final Thoughts

Samsung appears to be moving quickly toward the official release of One UI 9. With testing now covering multiple flagship, foldable, and mid-range devices, the company is focusing on stability, accessibility, security, and overall performance before the public rollout.

If everything stays on schedule, Galaxy users won't have to wait much longer to experience Samsung's latest software update.
