Samsung has begun seeding the second beta of One UI 9 to Galaxy S24, S24+ and S24 Ultra owners enrolled in its testing program, with the update landing in eligible markets starting September 15, 2026. Built on Android 17, the update’s headline addition is a set of four AI features that debuted first on Samsung’s newer hardware: My FanCam, Call Brief, Now Nudge, and a revamped card system for Now Brief.
Don’t expect this to show up on every S24 just yet. This is still experimental software, not the stable release that will eventually reach all Galaxy S24 owners, and access hinges on your country, exact model, and current software version. The first beta was confirmed only in the United States, India and South Korea, so there’s no guarantee the program has spread beyond those markets right now.
What matters more than the feature count itself is where these tools are coming from. Samsung is effectively porting capabilities already tested on the Galaxy S26, Z Fold 8 and Z Flip 8 down to a generation-old phone. For most S24 owners, that’s less an immediate upgrade and more a hint at where One UI 9 is headed.
My FanCam is the flashiest of the bunch. It can lock onto a chosen person in a video, track their movement, and automatically reframe the shot to keep them centered, with settings tailored to different video formats.
The remaining three features lean heavily on context. Call Brief surfaces information tied to a contact or conversation while you’re on a call, pulling from data already stored on the phone. Now Nudge watches what’s on your screen and suggests a relevant app, calendar event, or shortcut based on it. Meanwhile, the new Now Brief cards pull together details from Samsung Health, weather, and YouTube, and can be set to appear at specific times of day — the goal being a daily summary that feels more personalized rather than an entirely new function.
None of this is locked in yet. Features included in a beta can still change shape before the stable release, and there’s no promise they’ll roll out identically in every country once One UI 9 goes wide.
The update itself, carrying a build number ending in ZZI4, is a download north of 600MB, with the exact size varying by model and region. Alongside the new AI tools, Samsung has patched a handful of bugs: mistranslated text in Bixby Vision, a camera color optimization glitch, and an issue that could cause the Contacts app to crash unexpectedly.
Those fixes are a reminder of what betas are actually for — stress-testing Android 17 and One UI 9 before they go out to everyone. Bugs, instability and compatibility hiccups are still very much possible. Samsung is also widening its beta pool to cheaper devices, with the Galaxy A25 now accepted into testing in India.
Getting in, if your market qualifies, means signing into Samsung Members with a Samsung account and waiting for the program banner to appear for your device. Once enrolled, you can grab the update under Settings > Software update > Download and install. Samsung recommends backing up your data first, as always with beta software.
Samsung hasn’t said when the stable version of One UI 9 will actually arrive for Galaxy S24 devices. For anyone shut out of the regional beta, that release date matters a lot more than whatever beta 2 brings today.
