This chime comes from Samsung Galaxy phones, where it serves as a familiar default notification tone that millions of people hear every day. Because the sound is so widely recognised, clips of it began circulating online as a way to fake incoming messages in memes, reaction videos and pranks. Creators use it to make viewers check their own phones, to set up a text-based joke, or to add realism to a skit. Its short length and clean tone make it easy to drop into edits, which is why it remains a popular choice for phone and messaging humour.
