Android emergency alerts are system sounds built into Android phones for Wireless Emergency Alerts, the public warning system used for severe weather, tornadoes, Amber alerts and other urgent threats. The tone is designed to be loud and unmistakable so people notice it even when their phone is silenced. Clips of the sound spread on soundboards and social video platforms, where creators reuse it to parody official warnings, stage pranks and add instant urgency to short edits. Its recognisable buzz has kept it popular because almost anyone with an Android phone knows exactly what it means.
