The Galaxy S10 was Samsung's flagship phone released in early 2019, and its startup sound was part of the device's familiar boot sequence, heard every time the handset was switched on. As the phone became one of the most popular Android models of its era, the short chime spread beyond the device itself, appearing in unboxing videos, tech reviews and phone comparison clips. It remains in use today because it is instantly recognisable to Android users and works as a shorthand for a Samsung phone starting up.
