iPhones are full of hidden features that unlock their true potential. One such feature is the volume buttons, which do more than just control sound.
All iPhone models have two volume buttons, unlike many Android phones that use a single button. These buttons can perform tasks beyond adjusting volume, such as offering tactile control for photography, providing quick access to emergency services, or acting as a physical snooze button.
For emergencies, holding the side button and either volume button triggers the SOS function, which contacts emergency services and checks your Medical ID. On iPhone 14 Pro models, the SOS feature also includes satellite connectivity for poor cell service areas.
