The S25, S25 Plus and S25 Ultra feature modest upgrades, but are they enough to justify a big purchase? Here's how the phones stack up against each other, as well as previous Galaxy devices.

The Galaxy S24 FE that could be thought of as the Slim's predecessor is 8 mm thin, which isn't as thin as the 7.2mm Galaxy S25 that just debuted. One rumor suggests that the goal would be to approximate the Galaxy Z Fold 6, which is 5.6mm thin when unfolded, but another number being floated around is 6.4mm.

Though we’re getting a decently refreshed Galaxy S25 Ultra and an entirely new model in the S25 Edge, our hands-on Samsung Galaxy S25 review found that the baseline S25 has received a comparatively smaller update this year than either of its larger siblings.
