Over a year since it dipped into generative artificial intelligence, Samsung’s Galaxy S-series phones are now the vanguard for its gen-AI features. This year, we’re getting even deeper hooks into Google’s Gemini AI assistant and more built-in software tricks than ever before.

Here's our Samsung Galaxy S25 Ultra vs Galaxy S24 Ultra comparison. The very best of Samsung goes against last year's flagship.

The biggest overall changes to the design between the two Samsung Galaxy phones is likely the color options to choose from when making the upgrade. The Samsung S25 comes in Navy, Icyblue, Mint, Silver Shadow, Blueblack, Coralred, and Pinkgold. The Samsung S23 only has four color options to choose from.
