Samsung just slipped an unexpected update into its S24 lineup. No press fanfare. No countdown clock. Just a quiet roll-out that lands One UI 9 beta on Galaxy S24 phones sooner than many anticipated.
Remember when the beta program first expanded to the latest Fold7 and Flip7 hardware, plus the Galaxy S25 family? That was yesterday’s news. Today, the company has extended the Android 17-based One UI 9 beta to the Galaxy S24, S24+ and S24 Ultra — at least in three key markets: the US, India and South Korea.
The download is substantial. Expect a package of roughly 3.6GB, and firmware IDs finishing with ZZHL, EZHK or EZHL depending on your region and model. That’s not a patch; it’s a full preview build meant to surface new features and early bugs.
Not every S24 variant made the cut. The Galaxy S24 FE is conspicuously absent from this batch. Why? Samsung hasn’t said. It could be timing, certification, or simply a staggered testing plan. In other words, patience if you own the FE model.
Curious what this means for everyday users? Beta firmware usually brings early looks at interface tweaks, system-level features tied to Android 17 and fresh UX changes under the One UI brand. It also brings instability. Expect rough edges. Expect frequent updates. Expect feedback requests.
If you live in the United States, India or South Korea and want to try One UI 9 now, enroll through the Samsung Members app to join the beta program.
For developers and power users, this is an opportunity to test app compatibility and report issues before the broader release. For everyone else, it’s a chance to peek at where Samsung’s software is heading — while keeping a backup handy.
Keep an eye on the Samsung Members channel for rollout notes, bug-fix builds and the eventual wider release. Curious to try the new One UI features on day one? The invitation is in the app. Will you accept it?
