Samsung S5 with a slight jolt? Galaxy S5 shaking have a sound how to solve

Samsung mobile phone S5 in the ears before and after shaking with noise, this is due to the internal structure of the product, the flash using a non-fastening design, for mobile phone photography using AF (auto focus AF) function, the camera internal AF lenses need to move around the focus, and back and forth when shaking a slight noise is normal phenomenon, does not affect the normal use (the left and right shaking without this sound).

Note: This is the case, including other phones that support AF.
