Evolution of the Samsung Galaxy Ultra Series: A Comparison of S23, S24, and S25 Models

As the smartphone industry matures, the design of new devices appears to reach a plateau, where year-over-year changes become subtle. However, over a span of just a couple of years, these incremental updates can accumulate significantly. A prime example is the comparison between the Galaxy S23 Ultra, Galaxy S24 Ultra, and the upcoming Galaxy S25 Ultra—a trio that showcases how much can evolve within a short timeframe. The Galaxy S23 Ultra featured a curved screen, marking its design as the last of its kind in the Ultra lineup. In contrast, the Galaxy S24 Ultra introduced a flat display, which emphasized its newly rounded frame and thinner, uniform bezels. As for the anticipated Galaxy S25 Ultra, early information suggests it will feature even more refined rounded corners and slimmer bezels, potentially featuring flat sides as well.
