The Galaxy S4 was Samsung's flagship Android phone released in 2013, and its startup sound was part of the phone's standard boot sequence, heard by millions of owners every time they switched the device on. As the phone became one of the best-selling Android models of its era, the short jingle became closely tied to that period of smartphone history. Today it survives mainly through soundboards, nostalgia videos and tech edits, where it works as an instant audio shorthand for the early 2010s Android era.
