Samsung has started rolling out the first update after the One UI 8.0 release for both the Galaxy S24 Ultra and Galaxy S25 Ultra in South Korea.

Even though both devices already received the September 2025 security patch with the One UI 8 rollout, this new update keeps the same patch level and mainly focuses on stability improvements and security-related code refinements. No new features have been added in this release.

These additional roll outs never expand to other regions..it stays limited to Korea only...many a times before also i have observed this..

[Ankitastic26]

This update first came in Korea in September, no global yet, likely with October patch for India.

[S24ultra11]

I did my S25ULTRA oct security patch update yesterday i.e. 24th Oct. Although phone is smooth like before didn't found any hiccups. Battery is draining like crazy after update. Even idle overnight drain just doubled from 3-4% to 8% percent. Normal drain is also high.
