iPhone 17 camera clicking and high-pitched noise issue

I recently got a new iPhone 17 (base model) and noticed two things that seem unusual compared to my previous iPhones:

1. There’s a clearly audible clicking sound every time I open the Camera app.
2. When using the front camera, there’s a high-pitched noise or hiss that’s audible when I bring the phone close to my ear — and the same noise can even be heard in videos recorded with the front camera.

I haven’t experienced anything like this on my earlier iPhones, so I’m wondering — do other iPhone 17 owners hear the same sounds, or could my unit be defective?
