Xiaomi is a major Chinese smartphone maker whose devices are widely used in Asia, Europe and other markets, so its default phone sounds have become familiar far beyond its home country. This ringtone circulates online as a short standalone clip because people search for the exact tone they hear every day, want to set it on another phone, or need it for videos and memes about calls and notifications. Its simple, recognisable melody keeps it useful as a stand-in for any modern smartphone ringing, even for viewers who do not own the brand.
