Samsung One UI 8.5 rollout: which Galaxy devices get it first?

First overall: Galaxy S26 series

The Galaxy S26 series is the first Galaxy hardware associated with stable One UI 8.5 because it arrived with the software pre-installed . That is different from an over-the-air update: S26 buyers did not have to wait for a rollout wave to move from an older One UI version to One UI 8.5.

First update recipients: Galaxy S25 series

For Galaxy devices already in users’ hands, the Galaxy S25 series is first in line. Samsung’s official announcement says One UI 8.5 begins rolling out in Korea on May 6, 2026, and SamMobile reports that the Galaxy S25 series gets first dibs on the update .

That makes the Galaxy S25 family the practical answer for most people asking which existing Galaxy phones receive One UI 8.5 first. The rollout is still staged, so the same model may not see the update at the same moment in every country .

Samsung’s named early rollout wave

Samsung’s global newsroom says One UI 8.5 is expanding to more Galaxy phones and tablets and names these devices in the early expansion group :

• Galaxy S25 series
• Galaxy S25 FE
• Galaxy S24 series
• Galaxy S24 FE
• Galaxy Z Fold7 and Galaxy Z Flip7
• Galaxy Z Fold6 and Galaxy Z Flip6
• Galaxy Tab S11 series
• Galaxy Tab S10 series

This is the strongest official starting list. It should not be read as a complete model-by-model calendar for every Galaxy phone and tablet, because Samsung’s announcement says additional regions will follow but does not publish exact dates for every device variant .

When will other Galaxy phones and tablets get One UI 8.5?

Officially, Korea comes first on May 6, with additional regions following afterward . SamMobile reports that the wider rollout begins May 11 across several major regions, including Europe, India, North America, Latin America, Southeast Asia, Hong Kong, and Taiwan .

If your device is in Samsung’s named early wave, it is part of the confirmed expansion, but the exact arrival date can still depend on market and model. Separate reporting also notes that feature availability may vary by device and region, so not every Galaxy device should be expected to receive the identical One UI 8.5 experience at the same time .

For Galaxy models outside Samsung’s named list above, the cited Samsung announcement does not provide a confirmed date . The safest approach is to wait for a local Samsung notice or for the update to appear on the device itself.

Why the update may not show up immediately

A staged rollout is normal for a major Galaxy software release. Samsung says the rollout begins in Korea and then moves to additional regions, rather than launching everywhere at once . Regional timing, device model, and supported feature differences can also affect what users see .

To check manually, open Settings → Software update → Download and install. If no update appears, it may simply mean your market or device variant has not reached its rollout window yet.

Bottom line

The Galaxy S26 series got One UI 8.5 first by shipping with it. For existing Galaxy devices, the Galaxy S25 series leads the official update rollout, beginning in Korea on May 6, 2026 . Samsung’s named early wave then covers recent Galaxy S, Galaxy Z, and Galaxy Tab models, with broader regional availability reported from May 11 and exact timing still dependent on market and model .
