Samsung Pushes Galaxy S26 Series Closer to Android 17 Stability with One UI 9.0 Beta 4 Release
The road to Samsung’s highly anticipated, Android 17-based One UI 9.0 stable release has reached another major milestone with the official rollout of Beta 4 for the Galaxy S26 series. Arriving with firmware version ending in ZZG4 and weighing in at roughly 1.25GB, this latest build is currently hitting enrolled devices across Germany, India, Poland, South Korea, and the UK, with a US release expected to follow shortly. Rather than focusing on headline-grabbing new features, this update is a massive bug-squashing initiative aimed squarely at polishing system stability and fixing nagging interface glitches that testers complained about in earlier builds. Notably, it also bundles the July 2026 Android security patch to ensure that beta participants remain fully protected while they put the software through its paces.
According to the official changelog, Beta 4 resolves several annoying quirks, including an issue where the lock screen clock size would distort when rotating the phone, and a bug that caused the navigation bar to completely disappear during gaming sessions. It also optimizes the layout consistency of Live Notifications—specifically fixing an issue where countdown timer numbers were awkwardly cut off—and irons out performance lag when opening and closing the Quick Panel. Additionally, Bixby Routines actions, particularly those handling Bluetooth audio media volumes in vehicles and Privacy Display triggers, have been stabilized. With these critical visual and behavioral kinks finally ironed out, Samsung is rapidly narrowing down its checklist, signaling that the final, stable version of One UI 9.0 is just around the corner.
