Early One UI 8.5 leaks already point to Samsung's next Android skin being a much bigger update than One UI 8. Like One UI 8, One UI 8.5 will also be based on Android 16. Likewise, One UI 8 is based on the initial Android 16 release and not QPR1. Going by past trends, the company could have still based One UI 8.5 on the initial Android 16 release, but it's not doing so. One UI 8.5 being built on Android 16 QPR2 appears to be a direct outcome of that change.
