This chime comes from the set of notification tones preloaded on Samsung Galaxy phones, where short electronic alerts play for incoming messages and app updates. Creators started lifting these stock phone sounds for memes and short videos because the tone reads instantly as a new notification, even for viewers who never owned a Samsung. It now shows up in texting skits, fake message gags, and edits that need a crisp notification sound cue, in the same way game tones like the GTA V notification get reused far outside their original context.
