We would like to provide clarification regarding the noise you've heard when shaking your device. Rest assured, the noise you are experiencing is considered normal and is related to the camera's sensor. The camera sensor within your device may produce a slight noise or rattle when the device is shaken. This noise is not indicative of a defect or issue with your device. It is a characteristic of the camera's sensor and is designed to operate effectively within your device. #feedback Samsung
Inside the Galaxy mobile phone, there is a component that functions as an OIS (Optical Image Stabilization) to minimise shaking when taking pictures with the phone. If this small part is shaken while the camera is not operating, it may hit the internal structure and make a slight rattling sound.
The OIS is a function that detects hand shaking and corrects the lens by moving the lens in the opposite direction of the shake. Due to the different OIS sizes for each product, the sound may be relatively louder depending on the product. This is due to the characteristics of the OIS and is not a product defect. The sound does not affect the function and performance of the mobile phone. https://www.samsung.com/sg/support/mobile-devices/do-you-hear-a-small-noise-from-inside-of-the-devic....
