A survey circulating online seems to indicate that the Galaxy S25 phones will be announced on January 5 but I don't believe that to be true for a myriad of reasons.

Samsung is gearing up to launch the Galaxy S25 series on January 5, 2025, according to a leaked survey. The timing of this launch is earlier than expected, as the Galaxy S24 launched in late January, while the Galaxy S23 debuted in mid-February.

The Galaxy S24 featured a 6.2-inch screen, a slight increase from the 6.1-inch display on the Galaxy S23, with Samsung shrinking the bezels to add more screen space. Rumors tip the Galaxy S25 to have a 6.36 display which would match the size of the iPhone 16 Pro panel. Such a move could increase the size of the Galaxy S25 over the Galaxy S24
