The Galaxy X is one rumored name for Samsung's foldable phone, and as far as we know, it and the Galaxy S10 are separate devices. This makes perfect sense. The Galaxy S is a tried and true phone series, and Samsung wouldn't miss an enormous opportunity to crow about a special 10th anniversary edition.

Meanwhile, a foldable phone is an untested concept that's just getting its footing. As of today, there's one foldable phone on the market, the Royole FlexPai, and a lot of intentions from Huawei, LG and others. Samsung and other phone-makers will want to tread cautiously to see how buyers respond before bringing a foldable design into the mainstream Galaxy S lineup.
