Camera sounds

I have the iPhone X, when it’s on silent I can still hear the shutter sound from camera. Is there anyway I can turn it off? My old iPhone 6 phone didn’t have this problem, does this only happen to the newer models?

iPhone from some countries (example japan) the camera shutter sound cannot be turned OFF.

It doesn't matter which iPhone models old or new.

iPhone exported for certain countries, it's is illegal to silence the shutter sound.
