Stable One UI 9 is reportedly reaching the Galaxy S24 series, Galaxy Z Fold6 and Galaxy Z Flip6 in South Korea. Android Authority reported the device-specific rollout on October 6, 2026; availability in other countries was not confirmed in the sources available. If you own one of these phones elsewhere, Samsung’s broader rollout announcement does not establish that the update is already available in your region.
Where stable One UI 9 is available for these Galaxy phones
Samsung’s September 16, 2026 announcement said the One UI 9 rollout began that day for the Galaxy S26, S26+ and S26 Ultra, after its debut on the Galaxy Z Fold8 Ultra, Fold8 and Flip8. Samsung said it would expand gradually to other Galaxy devices. The announcement did not identify the S24 series, Fold6 or Flip6 as receiving stable software at that point. Samsung’s rollout announcement.
On October 6, Android Authority reported that stable One UI 9 was reaching the Galaxy S24 series, Galaxy Z Fold6 and Galaxy Z Flip6 in South Korea. Its report relied in part on screenshots shared by an X user. That is a South Korea rollout report, not confirmation of a worldwide release. Samsung’s announcement says expansion is gradual, but neither source confirmed when these models would receive stable One UI 9 in the US, Europe or other regions. Android Authority’s October 6 report.
Samsung’s September 1 announcement about expanding the One UI 9 beta named the Galaxy Z Fold7, Z Flip7 and S25 models in select markets. Beta availability is not confirmation of stable availability for the S24 series or the 2024 foldables. Samsung’s beta expansion announcement.

Reported download sizes and build details
Android Authority reported different package sizes depending on the phone and the software being replaced. These are estimates from that report, not fixed sizes for every device; the download shown on your phone may differ with its current build.
| Device group | Starting software | Reported package and build details |
|---|---|---|
| Galaxy S24 series | One UI 9 beta | About 500 MB; firmware S92xNKSUGEZIF and the September 5, 2026 security patch were reported. |
| Galaxy S24 series | One UI 8.5 | About 3.8 GB. |
| Galaxy Z Fold6 and Z Flip6 | One UI 9 beta | About 408 MB; build EZIH was reported. |
| Galaxy Z Fold6 and Z Flip6 | Not specified in the report | About 3.5 GB for the full package; the report did not state a separate starting build for this estimate. |
Because the reported sizes depend on the installed software, do not treat the smaller beta-to-stable packages as the expected download if your phone is still on One UI 8.5.

What to check before downloading
- Check your phone’s software update screen rather than assuming availability from reports about South Korea. The rollout may reach regions at different times.
- Note whether the phone is on the One UI 9 beta or One UI 8.5 before estimating download size; the reported package estimates differ substantially.
- Review the update details shown on your device. The report’s firmware identifiers and sizes are not a complete Samsung-published changelog and may not match every regional variant.
