Samsung has taken a significant step in enhancing its devices by releasing the stable version of One UI 7.0, based on Android 15, for the Galaxy S23 lineup. The update, which began rolling out in South Korea, covers the Galaxy S23, Galaxy S23 Plus, and Galaxy S23 Ultra, marking the resumption of the update process after a delay caused by a critical bug. The firmware package, identified as S91xNKSU6DYD9, is now available for South Korean users and is expected to reach other countries in the coming weeks, delivering not only performance improvements but also new features and a substantial boost in device security.
The rollout of One UI 7.0 started earlier in April 2025 for the Galaxy S24 series and the foldable Galaxy Z Flip 6 and Z Fold 6. However, a technical issue forced Samsung to pause the process, delaying the update for other models. The resumption last week allowed the company to extend the update to the Galaxy S23 lineup, reinforcing its commitment to keeping devices launched in 2023 up to date. The update includes the April 2025 security patch, which addresses 56 vulnerabilities, five of which are classified as highly critical and 37 as high-priority, ensuring greater protection against digital threats.
For users who participated in the One UI 7.0 beta program, the required download is approximately 1 GB, while those who were not in the program will need to download a larger 5 GB file. The arrival of Android 15 to the Galaxy S23 models underscores Samsung’s strategy to keep its devices updated with the latest Google operating system versions, offering an optimized user experience and innovative features that meet market demands.
Key features of One UI 7.0
- Audio Eraser: A Galaxy AI-powered tool that allows users to edit audio files, removing unwanted noise with precision.

Launch context and Samsung’s strategy
The release of One UI 7.0 for the Galaxy S23 lineup comes at a strategic moment for Samsung, which aims to maintain its leadership in the global smartphone market. Facing fierce competition from brands like Apple, Xiaomi, and Google, the South Korean company has doubled down on swift and consistent updates to differentiate its products. The Galaxy S23 series, launched in February 2023, remains one of Samsung’s most popular lineups, thanks to its robust performance and high-quality cameras, including a 200 MP sensor on the Ultra model.
Android 15, the foundation of One UI 7.0, brings significant improvements over its predecessor, including enhanced privacy controls, support for new media formats, and optimizations for large-screen devices. Samsung has tailored these advancements to its proprietary interface, adding exclusive features that reinforce the Galaxy brand’s identity. The Now Bar, for example, responds to demands for greater interactivity in modern interfaces, while Audio Eraser positions Samsung devices as versatile tools for content creators.
Samsung has also expanded its update support, offering up to four years of operating system upgrades and five years of security patches for the Galaxy S23 lineup. This long-term commitment is a key differentiator, particularly for consumers seeking durable devices. With One UI 7.0, the S23, S23 Plus, and S23 Ultra receive their second major system update since launch, cementing their relevance in the market even two years later.

The global rollout also includes other compatible devices, such as the Galaxy S24 FE, which has already received One UI 7.0 in select markets. Samsung has prioritized premium and high-end mid-range models, ensuring a broad range of users can access Android 15’s features. This approach underscores the company’s commitment to keeping its customer base updated, regardless of device or region.
Benefits for productivity and creativity
One UI 7.0 goes beyond technical improvements, introducing tools that enhance productivity and creativity. The upgraded writing and drawing features are particularly valuable for professionals who use their smartphones for note-taking, sketching, or document editing.
