Put this clip just after the on-screen message appears, preceded by the App Button Tap Sound for the send, then follow the reaction shot with the Bruh Sound Effect to close the beat.
About this sound
This short 1.2-second electronic chime is the Samsung notification alert, a clean phone tone for an incoming message. It feels instantly familiar and mildly awkward, like a text landing at the worst possible moment in a quiet room. It comes from the built-in tones on Samsung smartphones.
