If you have downloaded the new iOS 11 update onto your iPhone, you may have noticed the new "Emergency SOS" function under settings.

Apple's new feature allows you to quickly and quietly make an emergency call to 911, according to MacRumors.  Within the "Emergency SOS" function, your phone instructs you to "Rapidly click the sleep/wake button five times to quickly call emergency services."
