The Galaxy S5 arrived in 2014 as Samsung's flagship Android phone, and its power-on chime played every time the device booted up. The short melody became part of the daily routine for millions of owners, and after the phone was replaced by newer models it lived on as a nostalgia trigger. Today the chime circulates online in memes about old smartphones, tech nostalgia edits, and comedy skits where a character dramatically reboots a phone, because the three-second sound instantly signals the Android era to anyone who heard it back then.
