One UI 9 Beta Arrives on Galaxy S26 in India — ZZG4

Did your phone just buzz? Samsung has started rolling out the fourth One UI 9 beta to Galaxy S26 devices in India, and this build is stamped with the ZZG4 firmware tag. Short and to the point: if you opted into the beta, expect an over-the-air prompt soon.

The update weighs in at roughly 1.25GB, so you’ll want a reliable Wi‑Fi connection before you tap install. It’s a substantial download, but not a reinvention. Think refinement. The changelog focuses on fixes that tidy up everyday interactions rather than flashy new features.

Issues with clock size and Quick Panel layout have been addressed. The navigation bar behaves more predictably now, timer notifications pop up as intended, and the Routines app should stop throwing unexpected errors. These are the kind of corrections that make a phone feel less like work and more like a tool that stays out of your way.

Samsung also slipped the July 5, 2026 security patch into this release, so beta testers get a modest security uplift alongside the usability improvements. That’s helpful when you’re running pre-release software; stability and security often move in tandem.

The timing matters. One UI 9 is slated to make its official public debut on July 22 with the Galaxy Z Fold8, Fold8 Ultra, and Flip8. After that unveiling, Samsung will begin issuing One UI 9 as a broader update to older models — the S26 family’s beta program is effectively the rehearsal before the mainstage release.

Anyone in the beta should download over Wi‑Fi and back up their device before installing. Want smoother performance without waiting for the wide release? This ZZG4 build is worth a try — just be ready for a few more iterative updates between now and the public rollout.
