Samsung has begun deploying One UI 7, its latest interface based on Android 15, marking a significant leap in the Galaxy user experience. Since April 7, the update has been rolling out globally, starting with premium models like the Galaxy S24, Z Fold 6, and Z Flip 6, with plans to reach approximately 50 devices by June.

The Now Bar, a standout feature, displays real-time updates on the lock screen, such as exercise progress or Galaxy Buds music controls, without requiring users to unlock the device. These changes make interactions with the system more seamless and dynamic.
Integration with Google Gemini is a key highlight. Users can perform natural language searches, such as “Find nearby cafés with fast Wi-Fi,” and receive instant results. The system also simplifies settings adjustments with commands like “Increase screen brightness” or “Enable night mode.” These features are available on premium models like the Galaxy S24 and Tab S10, supporting languages including English, Spanish, Korean, and Portuguese.

The Galaxy A series enjoys a strong presence in Brazil, where consumers prioritize performance and affordability. One UI 7 delivers benefits like smoother animations and AI tools that streamline photo and video editing, meeting the needs of students and professionals. For tablets like the Galaxy Tab A9, the update improves functionality in educational apps, a critical factor in a country where mobile devices are essential for learning.
Samsung tailored One UI 7 for Brazilian Portuguese, with support for AI features like Writing Assist and natural language search. These tools aid in tasks such as drafting emails and managing projects. The company aims to strengthen its position in Brazil, where it faces competition from brands like Motorola and Xiaomi, through robust updates.
