Samsung's One UI 8.5 rolls out globally to Galaxy S25 devices first

Samsung began pushing One UI 8.5 to its Galaxy S25 family first, using the update to press its place in the smartphone AI race rather than treating it as a routine interface refresh. The rollout started in South Korea on May 6 and expanded May 11 into North America, Europe, India, Latin America, Southeast Asia, Hong Kong and Taiwan, with Samsung saying availability and timing can still vary by market and model.

The first wave reaches the Galaxy S25 series and Galaxy S25 FE, along with the Galaxy S24 series and Galaxy S24 FE, the Galaxy Z Fold7 and Galaxy Z Flip7, the Galaxy Z Fold6 and Galaxy Z Flip6, and the Galaxy Tab S11 and Galaxy Tab S10 series. Samsung has also said older flagships and several Galaxy A-series midrange models are scheduled for later stages, a sign that the company wants Galaxy AI to spread beyond its newest premium devices.

Samsung says One UI 8.5 is built on Android 16 and follows a four-month beta cycle with 10 beta builds. Samsung-focused reporting says users already on the beta may get a smaller update package than those moving up from One UI 8.0. The company is selling the release as an upgrade to communication and creative experiences across Galaxy phones and tablets, but the most concrete practical change highlighted in Samsung-focused coverage is the ability to completely customize the quick panel.

That split between marketing and utility sits at the center of Samsung’s current strategy. Samsung says Galaxy AI basic features provided by the company are free, while enhanced Samsung AI features and third-party AI features may come with different terms and possible fees. In other words, the company is widening access to some AI tools while leaving room for paid tiers that could deepen the gap between what every owner gets and what only some users can unlock.

The staged rollout also means not every Galaxy owner will see the update at the same time, even within the same country or carrier. That is likely to drive a wave of download checks, support questions and feature comparisons over the next several days, especially among S25 buyers who are first in line and older flagship owners who are still waiting. For Samsung, One UI 8.5 is more than a cosmetic patch: it is a test of whether “AI” on a phone means something users can feel every day, or mainly a faster way to brand incremental software changes.
