One UI 8 rollout begins for Galaxy S and Z series

One UI 8 has officially started rolling out to Samsung’s flagship Galaxy devices, marking the arrival of Android 16 on some of the company’s most popular smartphones and tablets. Samsung confirmed that the Galaxy S25 lineup was the first to receive the stable One UI 8 update in mid-September, followed by several other Galaxy S, A, Z foldables, and Tab series devices in the weeks ahead. The rollout schedule, which began in South Korea and Brazil, outlines a detailed timeline for each model, with updates continuing through October and November.

The Galaxy S25, S25+, S25 Edge, and S25 Ultra were the first in line, receiving the update on September 18. Shortly after, the Galaxy S24 models joined the list on September 25, while the Galaxy S23 series and S22 series are scheduled for early October. Even slightly older models like the Galaxy S21 FE are confirmed to receive One UI 8, showing Samsung’s effort to extend Android 16 to a wide range of users.

One UI 8 expands to Galaxy A series and tablets

Samsung has also included several mid-range smartphones in its roadmap. From late September onwards, devices such as the Galaxy A56 5G, A36 5G, and A55 5G have been added to the rollout plan. Popular models like the Galaxy A54 5G, A34 5G, and A73 5G are scheduled for October, ensuring that even non-flagship users will soon experience the Android 16-based interface.

Alongside smartphones, Samsung’s premium tablets are also part of the One UI 8 rollout. Starting in early October, the Galaxy Tab S10 series including the S10, S10+, S10 Ultra, and S10 Lite will be upgraded. By mid-October, the Galaxy Tab S9 and S8 series will follow, allowing tablet users to benefit from the refreshed design and improved performance.

Features and expectations with One UI 8

With One UI 8, Samsung introduces a smoother, more optimized user interface based on Android 16. While the exact features vary by device, the update emphasizes performance improvements, better multitasking, and enhanced privacy controls. The visual experience has also been refined, offering cleaner animations and more intuitive layouts that align with Android’s latest design standards.

For foldable devices like the Galaxy Z Fold6 and Z Flip6, the update is expected to optimize multitasking features and refine the Flex Mode experience. Samsung continues to strengthen its software support for foldables, ensuring that the Z Fold and Flip models receive timely updates alongside the flagship S series.

One UI 8 global rollout outlook

Although the initial schedules were shared for South Korea and Brazil, Samsung has confirmed that the One UI 8 update will gradually expand to other markets in the coming weeks. Regional variations are expected, meaning that the release dates may differ slightly depending on carrier approvals and local testing. However, Samsung’s overall commitment suggests that the majority of its premium Galaxy devices will run Android 16 before the end of the year.
