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.
Last week, Samsung released One UI 9 Beta 7 for the Galaxy S26 series. Samsung usually goes a few weeks between beta releases, and while we hoped a stable update would finally roll out, Samsung is back with another beta for the Galaxy S26 series. This marks the eighth One UI 9 beta for the Galaxy S26 series, and comes alongside the first One UI 9 beta for the Galaxy S25 series.
Tarun Vats notes on X that Samsung has begun rolling out One UI 9 Beta 8 for the Galaxy S26 Ultra in South Korea. This Android 17-based update comes with firmware version ending in ZZHM, the August 5, 2026 security patch, and is 513MB in size.
