Huawei is a Chinese technology company whose smartphones ship with a set of preloaded ringtones, and this melody became one of the most recognisable because so many owners left it on the default setting. As Huawei phones spread worldwide in the 2010s, the tune became familiar in offices, buses and classrooms. Users later extracted the audio and shared it online for use on other phones and in edited videos. It remains popular because the sound needs no explanation and immediately reads as a real incoming call.
