Xiaomi is a Chinese electronics company founded in Beijing in 2010, best known for its smartphones running MIUI and later HyperOS on Android. As its phones spread worldwide in the 2010s, the default incoming call melody became familiar far beyond owners, appearing in unboxing videos, tutorials and pranks shared online. Because millions heard the same tune in public places, it turned into a shared joke where bystanders check their own devices. That everyday recognition keeps the ringtone in use as a sound effect long after specific models change.
