Tablets, including the Galaxy Tab S9 and Tab S8, are part of the rollout, supporting heavier tasks like video editing and prolonged use. The broad scope of updated devices reflects Samsung’s strategy to unify the user experience across its diverse portfolio, ensuring consistency and quality across product categories.

• Galaxy S25, S25+, and S25 Ultra: pre-installed with One UI 7 since January 2025.
• Galaxy S24 and Z Fold 6: updated between September and October 2024.
• Galaxy A54 and Tab S9: rollout began in April 2025.

Technological advances in One UI 7

Samsung’s new interface offers more than a cosmetic refresh. Equipped with advanced artificial intelligence, it adapts to individual usage patterns, suggesting actions and automating routine tasks. This feature proves especially valuable for those relying on their smartphones for scheduling or professional activities, cutting down on manual adjustments and boosting daily efficiency.

A standout feature is the energy-saving system, which uses machine learning to monitor battery consumption. Tests show this technology can extend device runtime by up to 15%, a clear advantage for users spending long hours away from chargers. The interface also delivers smoother animations and simplified navigation, making system interactions more intuitive and enjoyable, even on entry-level models.

In the camera department, One UI 7 brings real-time editing tools directly into the native app. Functions like object removal and automatic image enhancement are now available across various models, enabling even casual users to achieve high-quality results. Paired with Galaxy hardware power, these AI-driven improvements elevate the photography experience, particularly in low-light or complex scenarios.

Security as a priority

Protecting user data is a core promise of One UI 7. The update introduces a more granular permissions system, giving users precise control over what information each app can access. This approach minimizes the risk of personal data exposure, a critical factor in today’s digital landscape where cyber threats constantly evolve.

Samsung Knox, the company’s security platform, has been upgraded to offer stronger defenses against malware and unauthorized intrusions. Paired with Android 15, it monitors suspicious activity in real time and blocks unapproved access, safeguarding sensitive information like passwords and documents. This combination makes Galaxy devices a reliable choice for both personal and professional use.

Devices compatible with One UI 7 also receive security updates for up to five years, depending on the model and region. This long-term support keeps devices shielded from emerging vulnerabilities, providing peace of mind for users investing in the brand. Support duration varies globally, with markets like Europe and Asia often seeing extended maintenance compared to other regions.

Rollout timeline in 2025

The One UI 7 deployment follows a structured schedule that started in 2024 and stretches throughout 2025. The Galaxy S24 series and foldables like the Z Fold 6 and Z Flip 6 were updated between September and October last year, kicking off the process. Now, in 2025, the expansion continues in distinct phases to cover the rest of Samsung’s portfolio.

From January to March this year, the Galaxy S23 and S22 series, along with Tab S9 and Tab S8 tablets, received the software. Between April and June, mid-range devices like the Galaxy A54 and M34 enter the lineup, reaching a broader user base. The second half of the year is reserved for final adjustments and updates to remaining devices, with a focus on unlocked models, which typically receive the update before carrier-locked versions.

• January to March: Galaxy S23, S22, and Tab S9 and S8 tablets.
• April to June: Galaxy A54, M34, and other mid-range models.
• July to December: tweaks and expansion to remaining devices.

Extended support for older devices

While newer models take center stage, Samsung hasn’t entirely sidelined older devices. The Galaxy S21, from 2021, and the S20, from 2020, won’t get the full One UI 7 experience but remain eligible for security patches for some time. This decision keeps these smartphones viable, though without access to the latest interface features.

Support duration varies by market. In regions like Europe, where consumers demand frequent updates, maintenance extends even to mid-range models. In other areas, such as parts of Latin America, premium devices take priority, leading to some variation in user experiences worldwide. This strategy balances innovation with legacy support, meeting the expectations of diverse audiences.

Optimizations for foldables and 5G connectivity

Samsung’s foldable devices, like the Galaxy Z Fold 6 and Z Flip 6, gain tailored enhancements with One UI 7. The interface now supports advanced multitasking, allowing up to three apps to run simultaneously on larger screens.
