One UI 8.5 Availability and Market Expansion

One UI 8.5 is now available in most major markets, bringing a sophisticated suite of visual improvements and customization options. Users can now enjoy a higher degree of personalization, including a redesigned quick panel that can be tailored to individual workflows.

The update also backports the highly anticipated horizontal lock feature, originally seen on the Galaxy S26, to the Galaxy S25 series. Furthermore, the integration of Galaxy AI has been deepened.
