Samsung Electronics Co. plans to launch an ultrathin version of its Galaxy S25 phone in the first half of this year, beating Apple Inc. to a promising new category.

The company previewed a handset called the Galaxy S25 Edge at the conclusion of its Samsung Unpacked presentation Wednesday in San Jose, California. Building on an S25 lineup that was unveiled earlier at the event — with the focus firmly on artificial intelligence features and not much in the way of major hardware upgrades — the Edge model is notable for its extremely thin profile.
