TL;DR
- Samsung has released the second One UI 9 beta for the Galaxy S26 series just two weeks after the first, moving significantly faster than the One UI 8.5 rollout.
- The 1,680MB update (firmware ZZEQ) includes the June 5, 2026, security patch and fixes key issues involving the lock screen, routine app, system status bar, and bulk message deletion.
- Currently live in the UK and South Korea, the update will soon hit the US and Germany, with the beta program expected to expand to India and Poland.
Samsung is moving much more quickly with One UI 9 than it did with One UI 8.5. The first One UI 9 beta arrived for the Galaxy S26 series about two weeks ago, and now, we’re already onto the second One UI 9 beta.
We’ve received the second One UI 9 update on our Galaxy S26 Ultra in the UK. This update comes with firmware version ending in ZZEQ, the June 5, 2026 security patch, and is 1,680MB in size. Of course, it is based on Android 17.
