Samsung has officially begun rolling out the Android 16-based One UI 8 update for its popular mid-range smartphones — the Galaxy M33, Galaxy M34, and Galaxy M35. The major firmware upgrade brings a cleaner interface, smoother animations, improved performance, and enhanced privacy controls across the trio of Galaxy M-series devices.
According Samsung’s official documentation, the rollout has started in multiple regions, including Europe and parts of Asia, and will expand globally in the coming weeks. The firmware build numbers vary slightly by model — for the Galaxy M33 it’s M336BXXU8GYI6, while the M34 (M346BXXU8EYI8) and M35 (M356BXXU5CYI8) receive similar version updates — all bundled with the October 2025 security patch and an OTA package size of around 2 GB.
What’s New in One UI 8 (Android 16)
The One UI 8 interface introduces a more refined look with adaptive colors, updated icons, and better motion smoothness throughout the system. The lock screen clock widget and daily activity targets have been redesigned for improved customization, while multitasking performance sees noticeable gains with optimized split-screen and pop-up view functionality.
Samsung’s core apps like Gallery, Internet, Calendar, and Messages have been updated with enhanced search, faster loading times, and a cleaner design. The Quick Share feature is now more seamless, and system privacy options have been expanded for greater control over permissions and background data access. Android 16 also introduces smarter resource management, leading to better battery efficiency and overall performance stability.
