Samsung has begun pushing the June 2026 security update to the Galaxy S26, S26+ and S26 Ultra, with the rollout starting in South Korea.
The 565.41MB release carries firmware version S94xNKSS3AZF1 and patches 45 security vulnerabilities found in the previous OS build.
The move follows Samsung's early-month announcement of the June 2026 patch for Galaxy phones, tablets and wearables, suggesting the S26 family is first in line for this cycle.
Samsung has also started extending the same June patch to older flagships, with the Galaxy S25 lineup receiving it in South Korea a day later.
