The sound comes from the startup chime used on older Samsung phones, the short tune that played when a Galaxy device was switched on. As those models were replaced by newer phones with different sounds, the original chime survived mainly through videos, memes and soundboards, where people shared it to trigger memories of their first smartphone. It remains popular because it is instantly recognisable to millions of former Samsung owners and works as a quick audio shorthand for the past, retro technology and simpler mobile days.
