Feature-wise, One UI 8 focuses on polish and useful AI: streamlined setup (choose gestures or buttons up front), a smarter Now Bar with live call/Do Not Disturb controls, tighter Galaxy AI integration, and deeper visual/translation smarts. Samsung also highlights privacy and Knox enhancements alongside improved multitasking on large screens 

Strategically, Samsung’s cadence mirrors a “newest devices first” approach, then fast beta diffusion to volume flagships and key mid-tiers—keeping current owners engaged while seeding Android 16 features broadly ahead of the stable build expected later this fall. 

If you’re joining the beta: back up your data, expect occasional app incompatibilities, and watch for region/slot limits inside Samsung Members. Stable timing can shift per model and market 

This expansion turns One UI 8 from a foldable showcase into a cross-portfolio preview—useful AI upgrades, quality-of-life tweaks, and enterprise-friendly privacy improvements landing early on Samsung’s most popular phones.
