Samsung began rolling out One UI 8.5 on Wednesday, May 6, 2026, starting in South Korea and putting the Galaxy S25 series — including the Galaxy S25 Ultra — and the company’s foldables at the front of the line.
The stable release follows a beta that ran from December 2025 through ten builds and first appeared pre‑installed on the Galaxy S26 when that phone launched on March 11, 2026. Samsung plans to move One UI 8.5 across roughly 25 Galaxy phones and tablets in the months ahead.
One UI 8.5 is built on Android 16 and is billed as a mid‑cycle feature update between One UI 8.0 and the forthcoming One UI 9. The update brings fresh animations and a Privacy Alerts feature, and it retools Bixby: Samsung says Bixby is now powered by Perplexity AI and can parse natural language to find features or change settings on the phone.
The rollout schedule tightens the stakes this week. After the Korea start on May 6, Samsung has scheduled a wider global wave to begin on May 11, 2026, covering Europe, India, North America, Latin America, Southeast Asia, Hong Kong and Taiwan.
Midrange Galaxy A users will not see the same package as the flagships. Samsung has confirmed that the last three generations of Galaxy A‑series phones will receive One UI 8.5 — specifically the Galaxy A56, A55, A54, A36, A35 and A34 — and the company already added the Galaxy A36 5G, Galaxy A37 and Galaxy A57 to the One UI 8.5 program. But older A‑series devices released before 2023 are unlikely to get the update.
The feature split is explicit: owners of phones released in 2023 or earlier will receive One UI 8.5 without the four new AI‑powered tools that debuted on the Galaxy S26. In other words, the S26’s most advanced AI capabilities remain tied to newer hardware, while a broader swath of devices will get the platform and interface improvements.
That division creates immediate friction. Samsung is prioritizing its newest flagships and foldables for the full experience, while leaving earlier flagships such as the Galaxy S23 series to wait longer for the same software and some AI features. The company has framed One UI 8.5 as a bridge release — not a new Android version — but the bridge does not carry every device across equally.
For owners who do receive the update, the changes are concrete: animations are refreshed and Privacy Alerts add visible controls for data use. Bixby’s shift to Perplexity AI is a notable platform change; Samsung says the assistant can now interpret natural language to locate settings and phone features when asked. The update’s core remains Android 16, and One UI 8.5 sits between the One UI 8.0 release that arrived on the Galaxy Z Fold 7 and Z Flip 7 in late 2025 and the expected One UI 9.
Operationally, the rollout is phased: the initial group is the Galaxy S25 series and foldables, with A‑series and older flagships following on a different cadence and with different feature sets. Samsung’s list of eligible devices and the inclusion of roughly 25 phones and tablets gives customers a concrete though staggered target for when they should expect the software.
What follows is predictable and consequential: the May 11 global wave will show how quickly Samsung can push the update beyond Korea and whether device owners find the feature gaps acceptable. The likely outcome is clearer now — Samsung is locking its top AI tools to the newest hardware while extending interface and privacy updates more broadly — a strategy that will define how users experience One UI through the rest of 2026.
