Samsung took a bold step in the tech market by announcing, in March 2025, the global launch of One UI 7, its new interface built on Android 15. The update, already rolling out, reaches millions of Galaxy line users, delivering a refreshed design, optimized performance, and cutting-edge artificial intelligence features. Models like the Galaxy S25 lead the charge, while dozens of other devices, including smartphones and tablets, receive the update throughout the year, reinforcing the South Korean company’s dominance in the mobile device sector.
In Brazil, excitement is palpable among consumers eager for improvements like modernized icons, smoother animations, and enhanced battery and memory management. One UI 7 isn’t limited to premium devices; it also breathes new life into older models like the Galaxy S22 and extends to mid-range options such as the Galaxy A54. Tablets from the Galaxy Tab lineup, including the S9, are also included in the rollout plan, broadening access to these innovations across diverse audiences and product categories.
This move underscores Samsung’s strategy to meet rising demands for faster, more secure, and customizable operating systems. With a more integrated ecosystem, the company aims to solidify its foothold in global markets, particularly in emerging regions like Latin America, where accessibility and quality heavily influence consumer choices.
Revamped design enhances user experience
The visual overhaul of One UI 7 stands out as a key feature, offering a sleeker and more functional interface for Galaxy devices. Redesigned icons with clean, consistent lines, paired with reorganized menus, make navigation more intuitive on both smartphones and tablets. Smooth animations, noticeable when opening apps or swiping between screens, elevate the experience, fulfilling a long-standing call for aesthetics combined with practicality. Devices like the Galaxy S24 and Z Fold 6 showcase how these changes make daily use more enjoyable.
Technical performance has also seen significant upgrades. RAM management has been fine-tuned to minimize crashes and speed up tasks, even under heavy multitasking. For devices launched years ago, like the Galaxy S22, these enhancements deliver a tangible boost in speed, while newer models like the Galaxy S25 fully harness Android 15’s capabilities. Customization options have expanded, letting users tailor the system’s look and behavior to their liking.
For tablets like the Galaxy Tab S9, the interface adapts to larger screens, streamlining tasks such as document editing and streaming. This blend of modern design and technical efficiency marks One UI 7 as one of Samsung’s most impactful updates in recent years, positioning the interface as a competitive advantage in a market where user experience drives loyalty.
Artificial intelligence boosts functionality
Integrating artificial intelligence in a practical way lies at the heart of One UI 7, reshaping how users interact with Galaxy devices. Virtual assistants now analyze usage patterns and offer personalized suggestions, such as automatic reminders or settings tweaks based on daily habits. This automation proves invaluable for those relying on their smartphones for demanding professional or personal tasks, transforming the device into a proactive and efficient tool.

Energy efficiency has taken a leap forward with algorithms that monitor battery usage in real time. Dynamic refresh rate displays balance visual performance and power savings, ensuring quality for gaming or video playback without draining the battery. In models like the Galaxy S25 and Z Flip 6, these optimizations extend battery life, bringing Samsung’s tech closer to rivals like the iPhone. Smart management of background apps further cuts resource consumption, freeing up RAM for other activities.
These advancements highlight Samsung’s focus on creating more sustainable and practical devices. The AI-driven features in One UI 7 not only enhance performance but also meet the expectations of users seeking innovation paired with longevity, bolstering the brand’s global competitiveness.
Rollout schedule spans 2025
The deployment of One UI 7 follows a phased plan, prioritizing newer devices before reaching mid-range models and tablets throughout 2025. This staggered approach allows for software refinements at each stage, ensuring stability and compatibility. In Brazil, availability may vary slightly by region, but users can check for updates directly in their device settings.
Key milestones in the rollout include:
- First quarter: Galaxy S25 (pre-installed), S24, Z Fold 6, and Z Flip 6 receive the update, fully leveraging their advanced hardware.
- Second quarter: Galaxy S23, S22, A54, A53, and M54 join the list, expanding access to millions worldwide.
- Third quarter: Galaxy Tab S9, S9+, S9 Ultra, and Tab S8 begin receiving the update, bringing the innovations to tablets.
This gradual strategy reflects Samsung’s commitment to democratizing access to its innovations, including models like the Galaxy A33 and M34. The phased transition ensures a consistent experience across devices and regions, strengthening the brand’s global presence.
Wide range of compatible devices impresses
A vast array of Galaxy devices is confirmed to receive One UI 7, spanning premium models to budget-friendly options. The update covers the Galaxy S, Z, A, M, and Tab series, featuring standout devices like the Galaxy S25 Ultra, Z Fold 5, A74, and Tab S9+. Even older models, such as the Galaxy S22, are included, showcasing Samsung’s dedication to extended support that keeps these devices relevant.
Tablets, like the Galaxy Tab S8 and S9, benefit from optimizations that enhance tasks like document editing and streaming, aligning their experience with smartphones. This integration strengthens the Galaxy ecosystem, appealing to users who value seamless connectivity across devices. Including budget lines like Galaxy A and M reinforces the strategy of catering to diverse audiences, especially in emerging markets like Brazil.
With this approach, millions of users gain access to an updated system, cementing Samsung as one of the most inclusive brands in mobile tech. The variety of compatible devices reflects the company’s effort to deliver innovation without sacrificing accessibility.
Enhanced security safeguards user data
Protecting user data is a top priority in One UI 7, which arrives with an updated Samsung Knox and added security layers. The system provides robust defenses against malware and cyberattacks, with granular controls over app permissions. Users can precisely define what data each app accesses, addressing growing privacy concerns in the digital age.
Real-time monitoring is another critical feature. When suspicious activity is detected, the system issues alerts and blocks threats before they cause harm, a vital safeguard for those handling financial transactions or sensitive information. This proactive protection raises the security bar for Galaxy devices, setting Samsung apart in a landscape where digital trust is essential.
Regular security updates will continue post-launch, particularly for older models. This policy enhances the reliability of the Galaxy lineup, positioning Samsung as a leader in user protection in a market where security and performance are intertwined.
Extended support benefits long-term users
Committed to device longevity, Samsung brings One UI 7 to models released years ago, such as the Galaxy S22 and A-series options like the A33. Beyond the new interface, these devices receive ongoing security updates, meeting demands for durable products and reducing the need for frequent hardware upgrades. This extended support stands out in an industry often criticized for rapid obsolescence.
Before the global rollout, a beta program ran in markets like South Korea and the United States, allowing users to test the interface and provide feedback. This process refined the software, delivering a stable and optimized version to the public. The initiative underscores Samsung’s emphasis on quality and reliability, ensuring a smooth transition to the new system.
The mix of innovation, security, and broad compatibility redefines mobile support standards. This effort establishes Samsung as a versatile brand, serving both premium device users and those with affordable models, keeping everyone connected to a modern, efficient ecosystem.
