From the tests I've seen, the difference between the S24 Ultra and the S25 Ultra isn't drastic. Once One UI 7 arrives on the S24 Ultra, I expect the gap to narrow even further—unless, of course, it's intentionally optimized to favor the S25 Ultra.
It’s clear that Samsung is following industry trends rather than setting them.
I have a feeling that the S26 Ultra will largely depend on what Apple does next.
There was a time when Samsung led the way in innovation, but now it seems to be more of a follower.
For now, I’ll be sticking with my S24 Ultra and waiting to see what Google or Apple bring to the table because the innovative spirit Samsung once had seems to be fading.
