Samsung's Galaxy line, launched with the original Galaxy S in 2010, built a familiar set of system sounds across the S, M, F, A, E and Z series and older GT-S and GT-I models. The call disconnect tone was part of that everyday dialer experience for millions of Android users, heard after ending a voice call. Clips of the isolated beep later spread through ringtones, soundboards and mobile editing packs, where its familiarity made it useful even for viewers who no longer own a Samsung phone.
