Samsung phones ship with a set of bright, distinctive alarm tones, and the loudest versions have become familiar far beyond the bedroom because the sound is instantly recognisable. Short clips of the tone circulate on soundboards and in short-form video, where creators use the jolt to wake characters, fake a missed alarm or interrupt a calm scene. Its appeal is practical as well as comic, since almost everyone has heard a phone alarm at full volume and knows the rush it brings.
