Apple plans to add buttons for adjusting the density and enabling 3D Touch in the iPhone 15 Pro, analyst Ming-Chi Kuo said.
Thus, Apple gets rid of mechanical buttons and becomes more reliable. The principle of operation will be similar to the Home mode in the iPhone 7, 8, SE2 and 3, where the application on the device is simulated using the Taptic Engine.
To do this, Apple will easily install two additional Taptic Engines. One will be possible for the operation of the power and lock button, and the second will control the volume control.
A similar change is expected in the iPhone 15 Pro Max. The iPhone 15 and 15 Plus close the mechanical buttons. [9to5Mac]
