My S10e has the sound too. It happens when changing zoom. I also have a Huawei Mate 20 X with 3 cameras on the back, and never hear any sound! I don't believe this is normal at all!
It's a NORMAL THING. Nothing buggy.
They opt for the dual aperture lens as from that of the S9 and S9+. Since it has dual aperture, the lens tends to open and closes its "HOLE" size. Is a good thing for photo taking. Something other competitors don't come close to like Apple and Huawei. We get better light control. It's a good thing it's mechanical, feels like an actual hardware operating like a DSLR camera. What's so wrong with that?

I have same concern
But I have a S9, and every photo using the rear camera gets blurry
This is happening since 3 days ago
I have done everything I can, also factory reset but the problem is still occurring
S9 without camera doesn't worth it
Samsung, should I return to Apple?
I bet for you but I'm not having good time
Please your help
