The Galaxy S25 series is now receiving what’s said to be the final and complete build of One UI 7, based on Android 15. The update has started rolling out in South Korea and is expected to reach other regions in the coming days.
What’s new?
The new firmware version, ending with “YD9,” brings several improvements and new features to the Galaxy S25 lineup. One of the key highlights is a set of stabilization optimizations aimed at improving performance across charging, camera functionality, security, and general system operations.
Samsung also notes that once you update to this build, you won’t be able to roll back to a previous One UI 7 version with a lower security level, so make sure you’re ready before you install.

As for new features, tipster Ice Universe reports that the update introduces Now Bar and Live Notification support for the Media Player, a new charging animation (previously seen in the beta), and other enhancements.
Update details
Here are the firmware versions included in the latest One UI 7 rollout:
- Galaxy S25: S931NKSU2AYD9
- Galaxy S25+: S936NKSU2AYD9
- Galaxy S25 Ultra: S938NKSU2AYD9
The update weighs around 780MB and includes the April security patch. To check if it’s available for your Galaxy S25, head to Settings > Software Update > Download and Install.
