The camera on the 1020 makes a few noises that I believe are expected for the design. The camera cover can be heard opening and closing when the camera is turned on or off, the camera moves within the phone a bearing (OIS), and the mechanical shutter can be heard when taking a picture.
When you tap on the back of the phone you're moving the camera module within the phone housing.
