Samsung One UI 8: Everything You Need to Know About Android 16

Samsung is making waves with One UI 8, its latest user interface built on Android 16. Unlike One UI 7, which introduced major changes, this eighth iteration focuses on refinement and optimization. Let’s explore everything this update has in store.

An Early and Strategic Launch

For the first time in its history, Samsung is releasing One UI 8 earlier than expected. This acceleration was made possible thanks to Google’s faster rollout of Android 16 to manufacturers. As a result, Samsung users get access to the latest innovations sooner than usual.

One UI 8 comes preloaded on the Galaxy Z Fold 7 and Galaxy Z Flip 7, with the rollout to older models beginning in September 2025. As always, premium devices are the first to receive the update.

What’s New in One UI 8

A Smooth Evolution

One UI 8 marks Samsung’s eighth major update to its interface. While it’s based on Android 16, the update feels closer to a version 8.1 than a true generational leap. The philosophy this time is clear: enhance what works instead of reinventing everything.

Subtle Visual Improvements

The interface keeps its familiar look, but Samsung has added a touch of freshness:

• Rounded buttons in some menus (e.g., Gallery)

• A new blur effect for backgrounds

• Dynamic wallpapers that change with the time of day

• Smoother animations and optimized transitions

• A redesigned Samsung Internet browser

Galaxy AI at the Center

Artificial intelligence takes center stage in One UI 8.
For example, the new Now Brief feature acts as a personal assistant by analyzing your daily habits and offering suggestions or actions at the right moment.

Practical Features Upgraded

One UI 8 isn’t just about looks. Samsung also made usability upgrades:

• Simplified file sharing with Quick Share

• Expanded support for Samsung DeX displays

• Improved calendar and reminders management

• New camera options, such as log video recording on the Galaxy Z Flip 6 and Fold 6

Official Release Dates (Stable) in the US, Canada, and France

• September 2025: Stable rollout begins for the Galaxy S25 series (S25, S25+, S25 Ultra) in the United States, Canada, and France.

Note: Exact dates may vary slightly by country, but this schedule applies broadly to Western markets.
