One of the main features of the iPhone 7 is your new home button, which no longer has a physical mechanism to function just as it does Force Touch.
Well, to make use of it we receive haptic responses in the form of a small vibration, which also happens when you use 3D Touch and can be disabled if not being comfortable with it.
Deactivating the haptic responses
- Access Settings
- In Settings, access the section Sound and Vibrations
- Once there, slide down and switch off the haptic responses
