How Can I Unlock My iPhone Without Pressing The Home Button?
Starting in iOS 10, Touch ID was changed to require a push on the Home button to unlock your Touch ID-equipped iPhone or iPad. If you would rather revert to the iOS 9-style of touching the Home button to unlock your device, there is a way to change this behavior in the Settings app.
Launch the Settings app and navigate to General > Accessibility > Home Button. Switch "Rest Finger to Open" to the on position. From now on you will be able to unlock your device by simplying touching the Home button (assuming that your display is already awake).
