Is the Galaxy S25 Ultra design an improvement?
Samsung continued using titanium for the body but reworked the form, the edges are slightly more rounded, making the phone more comfortable to hold. The 6.9-inch Dynamic AMOLED 2X display with a 120 Hz refresh rate and a peak brightness of 3000 nits is one of the best screens on the market.

The lighter weight (down 6g from the S24 Ultra) makes a difference in daily use. The S Pen slot remains, and the flat display is better for stylus work than curved screens.
How good is the Galaxy S25 Ultra camera?
The 200 MP main module remains, but Samsung put serious work into the processing algorithms. Night photography has improved noticeably, and the new telephoto lens with 10x optical zoom lets you capture detailed shots even from a great distance.
The 10x optical zoom is a genuine upgrade, previous models used digital crop beyond 3x. At 10x, details remain sharp enough for printing. For wildlife and sports photography, this is a game-changer.
