TL;DR
- Samsung has released the eighth One UI 9 beta for the Galaxy S26 series.
- The 513MB update (firmware ZZHM) includes the August 5, 2026 security patch.
- The update is currently live only in South Korea. We hope to see it go live in India, Germany, Poland, the UK, and the US very soon as well.

This update is currently live only in South Korea. At the time of writing, the update isn’t available on my Galaxy S26 Ultra in the UK. Samsung usually rolls out its One UI 9 beta updates in South Korea, India, the UK, Poland, Germany, and the US, so hopefully, other regions get the update soon.
We’ll keep you updated if we find any new features or bigger changes in this update. That being said, we’re now at the eighth (!!) beta release for the Galaxy S26 series. While a polished update is appreciated, I can certainly sympathize with S26 flagship users who may be getting impatient at this point.
