Overview
- SamMobile reports a One UI 9 firmware for the Galaxy S26 Ultra on Samsung’s servers, identified by build suffix BZC5 for the global model SM-S948B.
- The update under development is based on Android 17, which Google has progressed to Beta 2.
- Hands-on testing of the early build shows modest changes such as larger volume and brightness sliders in the quick panel.
- Parental Controls now appears as a standalone entry in Settings, moved out of Digital Wellbeing in this test firmware.
- The software is an early internal build with some screens still listing Android 16, and reporting points to a public beta before a likely mid‑2026 rollout alongside new foldables.
