Samsung announced the Galaxy S25, S25+, and S25 Ultra at its Unpacked event today. What is different from last year's models? With the phones themselves, not much, other than a new chipset and a wide camera. But pure AI optimism? Samsung managed to pack a whole lot more of that into its launch event and promotional materials. The corners on the S25 Ultra are a bit more rounded, the edges are flatter, and the bezels seem to be slightly thinner.
