The firmware is based on Android 15
A new firmware for the Galaxy S24 Ultra was discovered on Samsung servers. It is designated by the number S928BXXU2BXE2 and contains the One UI 7 interface based on Android 15.
The software is currently being tested in Europe, but tests will likely begin in other regions soon. Samsung may also soon start testing One UI 7 for its other flagships — Galaxy Z Fold5 and Galaxy Z Flip5.
Release of the final One UI 7 — the prospect is not close, but One UI 6.1 should be released very soon for mid-level models — Galaxy A53, Galaxy A54 and Galaxy S21 FE.
