In February 2025, Samsung disclosed the official list of Galaxy devices set to receive One UI 7, the interface based on Android 15, promising advancements in artificial intelligence, battery efficiency, and security. The update, rolling out in the first quarter of 2025, will first reach the Galaxy S25 line, pre-installed with the system, before extending to models like Galaxy S24, Z Fold 6, and mid-range A and M series devices. The announcement, made via an official statement, emphasizes performance and privacy optimizations, meeting the growing demand for extended support. The rollout will follow a staggered schedule, varying by model and region, aiming to deliver a smoother and safer user experience.
The new Samsung interface goes beyond visual changes. Advanced features, such as smarter assistants and AI-based photo editing tools, are among the highlights. The company also reinforces its commitment to security updates, enhancing protection against cyber threats.
- Key benefits: Improved power management, enhanced privacy controls, and more intuitive navigation.
- Supported models: Beyond flagships, mid-range lines like Galaxy A34 and M54 will also receive the update.
- Initial timeline: Updates begin between March and April 2025, prioritizing unlocked devices.
User anticipation is high, especially as Samsung solidifies its reputation for extended support, rivaling competitors in the Android ecosystem.
Confirmed One UI 7 features
One UI 7 will introduce a refreshed design with smoother icons and transitions, enhancing daily interactions. Samsung optimized the system to reduce energy consumption, using machine learning to adapt performance to user habits. This approach promises better battery life, particularly for models like the Galaxy S24 and Z Flip 6, which feature high-capacity batteries.
Additionally, the interface offers more robust customization tools. Users can tweak widgets, themes, and even automations based on daily routines. Integration with the Galaxy ecosystem, including smartwatches and tablets, has also been improved, ensuring more efficient device syncing.
Devices eligible for the update
The list of compatible devices spans both premium and mid-range models, reflecting Samsung’s strategy to democratize access to new technologies. Key devices include:
- Galaxy S25, S25+, and S25 Ultra, debuting with One UI 7.
- Galaxy S24, S23, and S22, including their Plus and Ultra variants.
- Foldables like Galaxy Z Fold 6, Z Flip 6, and earlier generations (Fold 5, Flip 5, Fold 4, Flip 4).
- Galaxy A series, notably A74, A54, and A34.
- Galaxy Tab S9 and S8 series tablets.
M-series devices, such as the Galaxy M54, are also included, expanding the update’s reach to emerging markets where these models are popular.
Focus on security and privacy
Security is a cornerstone of One UI 7. Samsung integrated a more granular permissions system into Android 15, allowing users to monitor and restrict app access to sensitive data like location and contacts. The Samsung Knox platform, the brand’s security suite, received updates to bolster protection against malware and unauthorized access.
Another advancement is enhanced encryption for locally stored data. Combined with regular security patches, this ensures Galaxy devices remain safeguarded against emerging vulnerabilities.
Artificial intelligence in the spotlight
Artificial intelligence plays a central role in One UI 7. Samsung implemented assistants that learn from user behavior, offering personalized suggestions like automatic reminders or app shortcuts. In photography, AI enhances image capture and editing, with features like object removal and real-time lighting adjustments.
These capabilities are especially relevant for models like the Galaxy S25 Ultra, equipped with high-resolution cameras. AI also optimizes video calls, reducing background noise and improving image quality in real time.
Rollout schedule
Samsung plans to start distributing One UI 7 in the first quarter of 2025, with initial batches targeting unlocked devices. Carrier-locked models may face delays depending on regional agreements. The company advises users to check software settings to confirm update availability.
In priority markets like the United States and South Korea, the rollout is expected to begin in March. In Brazil, the first devices are likely to receive updates between April and May, starting with the Galaxy S25 line and expanding to other models through the second half of the year.
Support for older devices
While the official list prioritizes models from the last three years, Samsung maintains extended support for older devices. Models like the Galaxy S21 and S20, though not on the main list, will continue receiving security patches for at least another year, depending on the region.
This approach underscores the company’s commitment to extending product lifespans, particularly in markets where consumers value long-term updates. The Galaxy A series, for instance, benefits from up to three years of major updates for some models, a standout feature compared to competitors.
Beta testing programs
Samsung launched beta testing programs for One UI 7 in select markets, allowing enthusiasts to try the interface before its official release. These programs, which began in January 2025, help identify bugs and optimize performance. In Brazil, beta access is limited, but Galaxy S24 users can sign up via the Samsung Members app.
Feedback from these tests is critical to ensuring the final version’s stability. The company has already addressed issues reported in earlier beta builds, such as crashes in third-party apps.
Competitiveness in the Android ecosystem
Samsung stands out among Android manufacturers for its update policy. While competitors like Xiaomi and Oppo offer shorter support periods, Samsung provides up to four years of major updates and five years of security patches for its flagship models. This strategy aligns with Google’s guidelines, which aim to standardize support across the Android ecosystem.
One UI 7 reinforces this competitive edge, delivering features that rival iOS, such as device integration and consistent updates. The company also collaborates with developers to optimize popular apps, like video editors and games, for the new interface.
Expectations in the Brazilian market
In Brazil, the arrival of One UI 7 is eagerly awaited, particularly by users of the Galaxy S and A series, which hold a significant market share. Samsung dominates the Android smartphone segment in the country, and the update is seen as a key factor in consumer loyalty.
Models like the Galaxy A54, popular for their cost-effectiveness, will gain new life with One UI 7, offering improved gaming and multitasking performance. The company also plans local campaigns to promote the update’s features, including tutorials on AI and privacy tools.
