That’s exactly what a lot of Galaxy fans are wondering about today, as leaker Erencan Yılmaz shares an early mention of One UI 9.5 on X:
In addition to revealing that internal reference to One UI 9.5, the source also asserts that we’ll see this release employed on the Galaxy S27 series, likely launching sometime in the first couple months of 2027. All of that sounds sensible enough, and as it turns out, this isn’t even the first time we’ve seen a One UI 9.5 reference.
