Android 4.4, released as KitKat in 2013, shipped with a set of short system tones for calls, messages and alerts, and voila was one of its light notification sounds. As older phones were replaced, those tones lived on through ringtone sites, soundboards and video edits, where creators kept them as a shorthand for an earlier era of Android. The clip survives today because it is short, clean and immediately tied to that period, making it useful for retro tech videos, app mock-ups and edits that need a familiar phone alert without using a modern default tone.
