Got to hold the S25 Ultra today at BestBuy. Did a side by side size comparison with my S24 Ultra.
But I have to say the flat sides with chamfered edges and rounded corners are big hit for me. Just the ergonomics of those changes will make it so much easier to hold IMHO.
I cannot wait to get this phone hopefully next week.
I also took my S-Pen from the S24U and it fits PERFECTLY in the S25U!
The Samsung Rep at the store kinda winked at me and said it does fit!
They have them on Amazon for a nice price and different colors.
