Samsung has announced the launch of its latest security patch for Galaxy devices, specifically the June 2025 update for the Galaxy S25 series. While these updates may lack the excitement of significant OS firmware releases like One UI 8, they play a crucial role in maintaining device security and ensuring optimal performance.

The June 2025 update is being rolled out first in Korea, Samsung’s home market. It applies to the Galaxy S25, S25+, and S25 Ultra.

Users can identify the update by the firmware build number that ends with AYE5. Although it is currently exclusive to Korea, Samsung typically acts swiftly to expand these updates to other regions.

Therefore, users in other areas can anticipate the update reaching them soon, potentially even by the end of the week. In addition to the security fixes, this update also includes a bootloader version update, which often indicates preparations for a more significant software upgrade in the future, such as One UI 8.

The June 2025 security patch addresses 19 specific vulnerabilities within Samsung software, patching potential weaknesses to enhance device protection. It also resolves several high-risk issues in the underlying Android operating system.

These fixes are essential in preventing unauthorized access to sensitive information and reducing the risk of malware exploitation, impacting user data and security, including data stored in Samsung Cloud for Galaxy Watch users. Galaxy S25, S25+, and S25 Ultra owners should watch their notifications for this update.

To check for availability, users can navigate to Settings, then go to Software update, and select Download and install. While the update might not be available immediately, it is likely just a few days away.
