Samsung Galaxy S24 Series Gets One UI 9 Beta Access
Samsung has delivered an unexpected update to its previous-generation flagship users. The Galaxy S24 series is now included in the One UI 9 beta testing program, built on Android 17. The move follows a broader beta expansion across many of Samsung’s devices, and signals the company’s continued commitment to supporting its older flagship lineup even with newer models already on the market.

Who Gets It and Where

The One UI 9 beta is available for the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra. The installation file size runs approximately 3.6 GB, and firmware versions vary by region, typically appearing as ZZHL, EZHK, or EZHL depending on where you’re located.

The test firmware is currently accessible to users in three countries:

Galaxy S24 FE owners will need to wait a bit longer. The One UI 9 beta has not yet been released for that specific model.

Part of a Wider Rollout

This expansion to the S24 series fits into a larger pattern. Samsung previously extended the beta program to the Galaxy Z Fold7, Z Flip7, and the current S25 lineup, including the S25, S25+, S25 Ultra, and S25 FE.

The company has a track record of bringing new software experiences to older devices, as seen with earlier updates like One UI 8.5. That approach has become a meaningful part of how Samsung keeps users engaged across a wide and aging product portfolio.

Joining the Beta

Eligible users with a supported S24 model in one of the participating countries can join through the Samsung Members app. Inside the app, look for the One UI 9 Beta registration section, confirm participation, and the system will prompt a download for the latest update package.
