The startup sound comes from the Nokia 105, a basic feature phone released in 2013 aimed at affordable, long battery life markets. Unlike the handset's famous ringtone, this boot chime was built purely to confirm the phone had powered on. Clips of the sequence later spread online as GIFs and short videos showing the logo animation with the sound, which helped it become shorthand for any old phone or system starting up. It remains popular in edits because the melody is short, clean, and understood without any context.
