Unusual iPhone 17 Pro Max Camera Sounds

I just bought a 17 Pro Max 256GB Silver and my phone makes a clicking sound when the camera app starts and when changing between photo and video mode (not changing the zoom). System haptic feedback switched off and in silent mode. I could also feel a vibration on the phone when the camera makes the clicking sound. Sounds and feels like a machinical issue. 

I’ve used every generation of iPhone since 3GS and never had any similar issues. Tried the display phones at Apple Store and none had the same issue. 

Returned the phone and waiting to purchase a new one when it’s restocked. (Hopefully from another batch)

Saw a thread on macforums where some other users have complained of the same issue. I tested a few phones at Apple Store and did not face such issue.
