Samsung One UI 9 Internal Testing Expands to More Galaxy Devices

Samsung is reportedly conducting internal One UI 9 testing across 49 Galaxy smartphones and tablets. The development has generated strong interest among Samsung users who want to know whether their devices may receive the next major update.

The reported testing list includes devices from the Galaxy S, Galaxy Z, Galaxy A and Galaxy Tab families. Internal testing does not guarantee that every listed model will receive the stable update at the same time.

Reported Galaxy S-Series Models

Devices reportedly involved in testing include:

  • Galaxy S25, S25+ and S25 Ultra
  • Galaxy S25 FE
  • Galaxy S24, S24+ and S24 Ultra
  • Galaxy S24 FE
  • Galaxy S23, S23+ and S23 Ultra
  • Galaxy S23 FE

Reported Galaxy Z-Series Models

The internal-testing list reportedly includes:

  • Galaxy Z Fold 7 and Z Flip 7
  • Galaxy Z Fold 6 and Z Flip 6
  • Galaxy Z Fold 5 and Z Flip 5

Reported Galaxy A-Series Models

Several mid-range models are also reportedly being tested, including:

  • Galaxy A57
  • Galaxy A37
  • Galaxy A27
  • Galaxy A17
  • Galaxy A07

The wider reported list also contains tablets and additional Galaxy devices.

Expected One UI 9 Features

One UI 9 is expected to build on Android 17 and may introduce:

  • Improved Galaxy AI features
  • Smoother animations
  • Better battery optimisation
  • Enhanced privacy controls
  • Updated notification management
  • Improved multitasking
  • New lock-screen customisation
  • Security enhancements

Some of these functions may remain exclusive to newer flagship devices because of processor or hardware requirements.

Internal Testing vs Stable Release

Internal testing is an early development stage. It is different from:

  • Developer testing
  • Public beta testing
  • Official stable rollout

Users should not install unofficial firmware or leaked software packages, as doing so can cause data loss, security problems or warranty complications.

How to Check for an Official Update

On a Samsung phone:

  1. Open Settings
  2. Select Software update
  3. Tap Download and install
  4. Install only the official update shown by Samsung

Back up important files before installing a major operating-system update.

Final Thoughts

The expanded internal testing indicates that Samsung is preparing One UI 9 for a broad selection of devices. However, users should wait for Samsung’s official eligibility list and regional rollout schedule before assuming that their phone will receive the update.
