iPhone 15 Pro ‘Action’ Button to Replace Role of Volume Buttons When Performing a Power Off/Force Restart

the leaker also claimed that the “Action” button will replace the volume up button for taking photos in the Camera app, with force-sensitivity enabling a light press to auto-focus the camera, a hard press to take a picture, and a hard/long press to record video.

Ok, this is a rumour, but it’s an interesting one. If Apple does this, it would bring the iPhone 15 Pro / Max closer to traditional camera behaviour. Coupled with the upgraded cameras and possible addition of the periscope lens, Apple seems geared to make the next iPhone iteration another potential winner.
