Haptic feedback is the vibration you can feel on supported iPhone models after you perform some actions, such as when you touch and hold any icon on the Home Screen. Haptic feedback is a type of technology that gives you a tactile response when you interact with different elements of your iPhone. Apples Haptic Touch technology is similar to 3D Touch but it doesnt rely on pressure. Instead, Haptic Touch kicks in when a user long-presses the screen, offering a small vibration as acknowledgement following the press. Haptic feedback can be customized in the Settings app under Sounds & Haptics.
