Key New Features
Photo Assist Revolution: Users can now edit photos continuously without saving each iteration. The feature consolidates all editing tools in one place, maintains full edit history, and lets users review all creations before selecting favorites—streamlining the entire creative workflow.
Smart Quick Share: The enhanced sharing system recognizes people in photos and proactively suggests sending images directly to those contacts, making photo distribution effortless after events or gatherings.
Storage Share: This game-changing feature enables seamless file access across Samsung devices (phones, tablets, PCs) directly through the My Files app—no manual transfers needed. Files remain on original devices but appear accessible everywhere.
Audio Broadcast: Samsung rebranded Auracast to Audio Broadcast with a cleaner interface featuring cosmic design and elegant gradients, improving the multi-device audio streaming experience.
How to Join Beta Program
Open the Samsung Members app (update from Galaxy Store first), scroll to Beta testing page, tap the One UI Beta card, accept terms, and follow on-screen instructions. Enrollment requires Samsung account login.
Beta 1 provides general stability suitable for daily driver use, though Samsung recommends backing up data first. Beta 2 on December 22 will expand to additional devices and possibly more countries.
The stable One UI 8.5 debuts with Galaxy S26 series in 2026, incorporating feedback from beta testers who help identify bugs and refine features before public release.
