One UI 8.5 leaves several headline features off older Galaxy phones, with SamMobile highlighting gaps on models such as the Galaxy S23 Ultra.
A 24-megapixel camera mode appears on the Galaxy S26 Ultra but is absent across the S25, S24 and S23 Ultra versions of the update, with no option to enable it through Camera Assistant.
Horizontal Lock, introduced on the Galaxy S26 Ultra, also does not reach older models, and the report says other missing features extend beyond the camera app.
The comparison suggests Samsung is tying parts of One UI 8.5's best experience to newer hardware, even when older flagship devices receive the same software update.
