Samsung Starts One UI 9 Rollout for Galaxy S24, Z Fold6 and Z Flip6 in South Korea
Samsung is rolling out the Android 17-based One UI 9 update to the Galaxy S24 series, Galaxy Z Fold6 and Z Flip6, starting in South Korea. See update sizes and the full rollout timeline.
Samsung has begun distributing its One UI 9 update, built on Android 17, to the Galaxy S24 series, the Galaxy Z Fold6, and the Galaxy Z Flip6. The latest wave follows earlier releases to Samsung's newer flagships and brings the company a step closer to covering its recent premium lineup.
The One UI 9 Rollout So Far
Samsung has staggered the release across several device generations:
- Mid-September: Galaxy S26 series
- Late September: Galaxy S25 series, Galaxy Z Fold7 and Galaxy Z Flip7
- Now: Galaxy S24 series, Galaxy Z Fold6 and Galaxy Z Flip6
One UI 9 first appeared on the Galaxy Z Fold8, Fold8 Ultra and Flip8 when they launched in July. Older flagships have therefore waited a few months, but the rollout is now well underway.
One UI 9 Update Size for Galaxy S24, Z Fold6 and Z Flip6
The download size depends on whether your device took part in the One UI 9 beta program or is updating directly from One UI 8.5.
| Device | From beta program | From One UI 8.5 |
|---|---|---|
| Galaxy S24 series | ~500MB | ~3.8GB |
| Galaxy Z Fold6 and Z Flip6 | ~408MB | ~3.5GB |
Since the full update is several gigabytes, connect to Wi-Fi and make sure the battery is well charged before installing.
Availability: South Korea First, More Regions to Follow
As with earlier One UI 9 releases, Samsung is starting in its home market of South Korea. The update should reach more countries over the coming days and weeks, though the company hasn't announced a regional schedule. Timing can vary by country and carrier.
To check for the update, go to Settings > Software update > Download and install on your device.
Summary
Samsung's One UI 9 and Android 17 rollout now includes the Galaxy S24 series, Galaxy Z Fold6 and Galaxy Z Flip6, after reaching the S26, S25, Fold7 and Flip7 in September. Owners of these devices outside South Korea should expect the update to arrive in the near future.
