Tripling tapping the Home button (on iPhones with one) activates the Accessibility Shortcut, a quick way to turn features like VoiceOver, Zoom, or Magnifier on/off, but you must first set it up in Settings > Accessibility > Accessibility Shortcut to choose which features activate. If only one feature is selected, it toggles on/off instantly; if multiple are chosen, a menu appears to select one.
Triple-click the side button or Home button to turn the accessibility features of your choice on or off. Go to Settings > Accessibility > Accessibility Shortcut, then select the features you want. If you select only one feature, the feature is immediately turned on or off when you click the button shortcut.
