Samsung Hits Fourth One UI 9 Beta for Galaxy S26: Bug Fixes and July Security Patch

Samsung’s One UI 9 Beta Program Continues with Update Number Four

It has been roughly a month since Samsung dropped the third One UI 9 beta for the Galaxy S26 lineup, and today, the company is keeping the momentum going. The fourth beta build has officially started rolling out, making its first appearance for users in India with the firmware version ending in ZZG4.

If you have already signed up for the One UI 9 beta program, you can expect an over-the-air notification to hit your device shortly. The update weighs in at approximately 1.25GB, so it is a good idea to hop on a stable Wi-Fi connection before hitting that download button.

What’s Fixed in the Latest Beta?

Samsung is clearly focusing on stability as we get closer to the final release. This latest build brings a series of meaningful bug fixes meant to smooth out the user experience. Key improvements include:

Clock and Navigation: Adjustments to clock sizing and navigation bar responsiveness.
Quick Panel: General polish to the Quick Panel interface.
App Performance: Fixes for timer notification issues and various squashed bugs within the Routines app.
Security: The latest build arrives with the July 5, 2026, security patch pre-installed.

Looking Ahead: The Foldable Launch

The anticipation for the stable release of One UI 9 is building, as the software is set to headline the upcoming Galaxy Z Fold8, Fold8 Ultra, and Flip8 devices. We won’t have to wait long to see the full picture—Samsung has officially confirmed their next Galaxy Unpacked event for July 22. Once these new foldables hit the market, we can expect the update to start rolling out to a wider range of legacy Samsung devices shortly thereafter.
