On Tuesday, August 5, 2025, Samsung announced the expansion of the One UI 8 beta program, based on Android 16, to new devices in the Galaxy lineup. The update, already in testing since May on the Galaxy S25 series, will roll out next week to models like the Galaxy S24, Z Fold 6, and Z Flip 6 in markets such as South Korea, the United States, the United Kingdom, and India. The initiative aims to enhance user experience with smoother navigation, enhanced security, and revamped layouts for native apps. The South Korean company, known for its commitment to customized systems, has not yet confirmed a release date for Brazil, but anticipation is high among users. The beta program will allow consumers to test innovative features before the stable version launches in the coming months.
The new interface promises to optimize smartphone performance, focusing on usability and security. Samsung emphasized that One UI 8 will bring visual and functional improvements without major aesthetic overhauls, prioritizing system stability. The expansion of the public beta reflects the company’s commitment to refining the experience before the global rollout.

Beta public expansion timeline
Samsung confirmed that the next phase of the beta program will begin the week following the announcement, prioritizing models like the Galaxy S24, S24+, S24 Ultra, Z Fold 6, and Z Flip 6. These devices will receive the One UI 8 beta in select markets, including South Korea, the United States, the United Kingdom, and India. In September, the company plans to expand the program to other models, such as the Galaxy S23, S23+, S23 Ultra, S23 FE, Z Fold 5, Z Flip 5, A36 5G, A55 5G, A35 5G, and A54.
While the initial device list is robust, the lack of information about the beta’s arrival in Brazil has raised questions among users. Social media posts indicate that Brazilian consumers are eager, though some believe the wait could extend another month. Samsung has not yet released an official timeline for the Brazilian market, but the company typically rolls out updates in waves, starting with priority markets.

Features like Now Brief, a centralized panel for notifications and reminders, will be available on more devices, enabling efficient task management. Additionally, the Quick Share functionality has been improved with more flexible visibility controls, simplifying file transfers between Galaxy devices.
The Samsung ecosystem also shines with the new interface. Compatibility with devices like the Galaxy Buds 3 and Buds 3 Pro has been expanded, incorporating integration with Google’s AI assistant, Gemini. This feature enables more natural voice commands and contextual responses, enhancing the experience across connected devices.

Optimizations for foldable devices
Foldable models, such as the Galaxy Z Fold 6 and Z Flip 6, receive special attention in One UI 8. The interface was optimized to leverage the unique formats of these devices, with improvements in split-screen multitasking. Users can now resize apps more smoothly, switching between them with simplified gestures. Additionally, the Generative Edit feature, exclusive to foldables, allows side-by-side comparison of edited and original photos with synchronized zoom.
Samsung also announced that the new Galaxy Z Fold 7, Z Flip 7, and Z Flip 7 FE, launched in July 2025, come with the stable version of One UI 8 pre-installed. This reinforces the company’s strategy of prioritizing premium devices for new technology adoption, while older models receive gradual updates.
Expectations for the Brazilian market
The absence of an official timeline for Brazil has sparked speculation among users. Samsung typically adapts its rollouts to each country’s regulatory and logistical requirements, which may explain the lack of confirmed dates. However, the popularity of the Galaxy lineup in Brazil, particularly the A-series and S-series, suggests the company will prioritize the national market soon.
The public beta expansion indicates that the stable One UI 8 version is nearing release. Based on past patterns, the global rollout is expected to begin between August and October 2025, with flagship devices receiving the update first. Brazilian users can monitor updates through the Samsung Members app or device software settings.
- Tips for tracking the update in Brazil:
- Regularly check the Samsung Members app.
- Go to Settings > Software Update.
- Follow Samsung’s official channels for announcements.
Performance and usability advancements
One UI 8 also promises improvements in overall device performance. Samsung optimized Android 16 resource usage, reducing battery consumption and enhancing system responsiveness for demanding tasks like gaming and multitasking. The seven-year update commitment for flagships, starting with the Galaxy S24 series, ensures that newer devices will remain updated until 2032.
For older models, such as the Galaxy S22 series, One UI 8 will still be available, though priority will be given to recent releases. The company is also testing the interface on mid-range devices like the A-series to ensure consistent compatibility and performance.
- Performance benefits:
- Lower battery consumption with Android 16 optimizations.
- Support for multitasking on foldable devices.
- Compatibility with devices released since 2022.
