GoKawiilSamsung expands stable One UI 9 to Galaxy S25, Z Fold 7, Z Flip 7 in Korea
Samsung has begun pushing the stable One UI 9 update, based on Android 17, to the Galaxy S25, S25 Plus, S25 Ultra, Galaxy Z Fold 7 and Galaxy Z Flip 7 in Korea. Beta testers are receiving a smaller ~535MB download to move to the final build, while users still on One UI 8.5 get a much larger update package of around 3.8GB. The rollout follows the update's earlier launch on the Galaxy S26 line and is expected to expand to the US soon.
GoKawiil's interpretation of the reporting above, not reported fact.
Staggered regional rollouts let Samsung catch bugs in one market before pushing updates globally, which could mean US and other international users see the stable build within weeks rather than months. The gap in download sizes between beta and non-beta users highlights how incremental updates work versus full firmware replacements, a distinction that affects update time and data usage for consumers.
- Stable One UI 9 is now hitting Galaxy S25 series and Z Fold 7/Flip 7 devices in Korea.
- Beta testers get a smaller ~535MB update, while non-beta users download a full package near 3.8GB.
- A wider rollout, including to the US, is expected to follow soon.
