Samsung has started the One UI 9 update. Check when your Galaxy may receive it
Samsung has started the stable One UI 9 rollout based on Android 17. It began on 16 September 2026 in South Korea for Galaxy S26, S26+ and S26 Ultra. Galaxy Z Fold8 Ultra, Z Fold8 and Z Flip8 shipped with the software.
That does not mean every eligible phone receives it on the same day. Rollouts vary by model, country and operator. Below we separate devices with stable software from reported dates and models that are only expected to qualify.
The key distinction is between phones that shipped with One UI 9, models whose stable rollout has officially started, devices that remain in beta and older Galaxy phones expected to qualify only from Samsung’s support policy.
Which phones already have One UI 9?
| Models | Status on 28 Sep 2026 | What it means |
|---|---|---|
| Galaxy Z Fold8 Ultra, Z Fold8, Z Flip8, Galaxy S26 FE | Stable software | These devices shipped with One UI 9 out of the box. |
| Galaxy S26, S26+, S26 Ultra | Rollout in progress | The stable rollout started in Korea on 16 September and has also been confirmed for selected US carrier variants. Other markets are being added in stages. |
| Galaxy S25, S25+, S25 Ultra, S25 FE, Z Fold7, Z Flip7 | Beta programme | Samsung officially expanded the One UI 9 beta to these models. The previously cited 28 September date should no longer be treated as a confirmed stable-release date. |
| Galaxy S24 / S24+ / S24 Ultra / S24 FE and the Galaxy S23 series | Beta / testing | One UI 9 testing is under way in selected markets, but Samsung has not published a complete global stable-rollout date. |
| Other eligible models | Waiting | There is still no complete worldwide schedule covering every country, carrier and device. |
The biggest change versus earlier schedules concerns the Galaxy S25 and Z7 foldables: 28 September should no longer be treated as a guaranteed update day. Samsung is rolling One UI 9 out in stages, and availability is only confirmed when the stable package actually appears in a given market.
Using a Galaxy S26? Match the case to the exact model
One UI 9 changes the software, but it does not change the phone’s dimensions. Choose the category for the S26, S26+ or S26 Ultra — cases are not interchangeable between these models.

In mid-September, 28 September appeared in rollout material for the Galaxy S25 series, Galaxy Z Fold7 and Z Flip7. Samsung later stopped listing that specific day and returned to broader, staged-rollout wording.
As of 28 September 2026, stable One UI 9 is confirmed for the Galaxy S26 series in Korea and selected US carrier variants. Galaxy S25, S25+, S25 Ultra, S25 FE, Z Fold7 and Z Flip7 remain in the beta programme in selected markets. We therefore no longer present 28 September as a confirmed stable-release date.
The Galaxy S24 and S23 series are also being tested with One UI 9, but earlier October timelines should be treated as estimates until Samsung publishes a schedule for a specific market and model.
Which older Galaxy models may qualify?
Recent flagships and mid-range phones still inside Samsung’s Android-upgrade policy are the strongest candidates. That includes recent S, Z and selected A-series generations, but a complete global list with dates has not been published. The safest check is the original support commitment for your exact model and market, not a copied internet list.
The high-probability group includes the Galaxy S25, S24 and S23 generations with selected FE variants; Z Fold7/Flip7, Fold6/Flip6 and Fold5/Flip5; newer Galaxy A models with long support, including A56 and A36; and recent Galaxy Tab S tablets that remain inside their major Android-upgrade window. This is a compatibility forecast, not an official date list.
What is new in One UI 9?
- My FanCam for easier subject tracking in video.
- Editable and generative Now Brief cards plus contextual Now Nudge suggestions.
- Interpreter Thread View and improved document scanning.
- Voice Recorder summaries, Security Brief and Privacy Alerts.
- Scam Detection, Warranty and Care features, with availability depending on country and device.
When will One UI 9 reach Europe?
Samsung's global announcement confirms that the rollout starts with the Galaxy S26 series, but it does not provide a complete model-by-model schedule for every European market. As of 28 September, stable builds are confirmed in Korea and on selected US carrier variants; European availability can still differ by country and model.
If your Galaxy S26 still does not show the update, this does not mean there is a problem with the phone. Check Settings → Software update → Download and install and Samsung Members. For the Galaxy S25 and Z7 series, wait for confirmation of the actual stable rollout rather than relying on the earlier 28 September date.
How should you prepare for installation?
- Back up important photos, messages and authentication codes.
- Charge the battery and connect to reliable Wi-Fi.
- Keep several gigabytes of free storage.
- Update important apps after the system restarts.
- If battery use is temporarily higher, allow a day or two for indexing before judging the update.
Do not install firmware intended for another region solely to get the update earlier unless you understand the warranty, compatibility and data-loss risks.
What if the update still does not appear?
- check the exact model number and country of distribution
- restart the phone and check again after several days
- verify whether a beta programme requires a separate withdrawal or package
- do not treat a Korean or US launch as proof of availability in Europe
- allow extra time for carrier-branded firmware
Repeated manual checks cannot make Samsung release a package for a CSC region that has not entered the rollout wave.
