Samsung has initiated the rollout of the stable One UI 9 update for Galaxy A57 smartphones in Europe. The release is identified by build numbers A576BXXU6BZIE, A576BOXM6BZIE, and A576BXXU6BZIE, as reported by industry observer @tarunvats33.
While the update is currently targeting European devices, there is an expectation for a broader regional release starting October 12, 2026. Samsung has not yet provided an official schedule for the global distribution of this firmware.
Following the Galaxy A57, the company plans to extend the One UI 9 update to the Galaxy A36 and Galaxy A56 models. These devices are expected to receive the software package within the current week.
The One UI 9 interface, built upon Android 17, introduces significant changes to the system. Key features include a redesigned quick settings panel, enhanced animation smoothness, and expanded customization options for the lock screen.
The update integrates Galaxy AI capabilities, focusing on generative tools for text and photo processing. Additionally, the system includes an advanced contextual search feature and optimizations designed to improve battery life.
