One UI 7 brings Android 15 to 46 Galaxy phones and tablets in 2025: explore AI upgrades and 5G enhancements

Samsung announced in April 2025 the expansion of One UI 7, its interface based on Android 15, to 46 devices in the Galaxy lineup, covering smartphones, tablets, and foldables. The update, which began rolling out in 2024, reaches from the newly launched Galaxy S25 series to mid-range models like the Galaxy A54, delivering advanced artificial intelligence, a refreshed design, and optimized 5G connectivity. With this move, the South Korean tech giant strengthens its commitment to providing a unified and accessible experience to millions of users worldwide, including Brazil, a key market for the brand. The rollout is phased, ensuring devices across various categories receive the new features throughout the year.

Artificial intelligence stands out as the centerpiece of One UI 7, with assistants that learn user habits and suggest practical actions, such as organizing schedules or tweaking power settings for efficiency. The design has been revamped with streamlined icons and smooth animations, making navigation more intuitive on both smartphones and tablets. Connectivity also sees significant upgrades, with reduced latency and improved stability on 5G networks, which are becoming the standard in many regions. Tablets like the Galaxy Tab S9 gain enhanced multitasking capabilities, while foldables such as the Z Fold 6 leverage flexible displays with greater efficiency.

Samsung’s strategy balances innovation with accessibility, catering to users of both premium and mid-range devices. In Brazil, where models like the Galaxy A54 and M34 are widely popular, the update promises to elevate the user experience with features previously exclusive to flagships. The company estimates that over 100 million devices will be updated by the end of 2025, positioning One UI 7 as one of the most extensive software rollouts in its history.

Initial rollout milestones

The deployment of One UI 7 kicked off in the second half of 2024, starting with premium devices like the Galaxy S24 series and foldables Z Fold 6 and Z Flip 6. In 2025, the update extends to a broader range, encompassing the S, Z, A, M, and Tab series. The Galaxy S25 lineup, launched in January 2025, came pre-installed with the new interface, harnessing next-generation processors to deliver seamless performance in tasks like video editing and social media browsing.

Devices such as the Galaxy S24, S24+, and S24 Ultra received the update in September 2024, showcasing noticeable improvements in battery life and photography. The camera app now uses AI to make real-time adjustments, such as removing unwanted objects or enhancing lighting, producing near-professional results. Users report that these tools make daily tasks more efficient, particularly for work or entertainment purposes.

Foldable devices were also prioritized. The Galaxy Z Fold 6 and Z Flip 6 received tailored enhancements to maximize flexible displays, enabling users to run up to three apps simultaneously with simplified navigation. This functionality suits professionals juggling spreadsheets, emails, and video calls, as well as enthusiasts enjoying gaming and streaming in unique formats. Early feedback from tech communities praises the smoothness and versatility of the updated devices.

  • Galaxy S series: S25, S25+, S25 Ultra, S24, S24+, S24 Ultra, S23, S23+, S23 Ultra.
  • Galaxy Z series: Z Fold 6, Z Fold 5, Z Flip 6, Z Flip 5.
  • Galaxy Tab series: Tab S9, S9+, S9 Ultra, Tab S8, S8+.

Artificial intelligence redefines usability

One UI 7 takes artificial intelligence to new heights, with assistants that analyze user patterns and provide tailored suggestions. For instance, the system might recommend shortcuts for replying to messages or adjusting display settings based on the time of day, minimizing manual tweaks. On devices like the Galaxy S25 Ultra, AI optimizes processor performance, balancing power and efficiency for tasks ranging from gaming to photo editing.

Photography benefits significantly. The native camera app now removes background noise in videos and corrects portrait imperfections automatically. These tools, once limited to paid software, are available even on mid-range devices like the Galaxy A54, broadening access to high-quality features. Tests show battery life can improve by up to 15% during heavy use, such as extended streaming, thanks to intelligent power management.

Customization options have also expanded. Users can personalize the interface with detailed themes and widgets, creating a unique experience. On tablets like the Galaxy Tab S9, AI enhances multitasking, allowing multiple floating windows without performance dips. These advancements reflect Samsung’s focus on making devices more intuitive and aligned with modern demands.

Enhanced security for a digital age

Safeguarding personal data is a core focus of One UI 7. The interface introduces granular permission controls, letting users restrict app access to features like location, camera, or microphone. For example, location access can be limited to when an app is actively in use, reducing risks of unwanted tracking. This approach resonates in a world where privacy concerns are increasingly prominent.

Samsung Knox, the company’s security platform, has been upgraded with real-time monitoring, blocking suspicious activity before it causes harm. Paired with Android 15, the system provides robust defenses against malware, critical for users storing sensitive data like financial information. Premium devices, such as the Galaxy S25, include additional protective layers, ensuring confidence in online transactions.

Compatible devices will receive security updates for up to five years, depending on the model. This policy extends device longevity, particularly in markets like Brazil, where frequent upgrades are less common. The strategy bolsters Samsung’s credibility in an increasingly complex digital landscape, serving both individual and corporate users.
