South Korea got the Galaxy S25 FE’s May 2026 security update first, with Samsung pushing firmware S731NKSS7BZE1 in a 291.31MB download.
The patch fixes 36 security issues carried over from the previous OS version, extending the update a day after Samsung covered the base, Plus and Ultra S25 models.
Samsung is expected to expand the rollout to other markets in the next few days through Settings > Software update > Download and install.
Earlier this month, the Galaxy S25 FE received stable One UI 8.5, and users who have not installed it may need that software before getting the new security patch.
Is the relentless pace of security updates creating a more secure phone or a buggier experience?
With 7-year software support, is the battery now the weakest link in smartphone longevity?
