There is a rattling sound when I shake my device. What is it?


The sound is due to the Camera Lens Barrel required to operate the Auto Focus function.

Your Galaxy device supports the Auto Focus feature required for high quality and high resolution shots with the camera. The Camera module “Lens Unit”, Image Sensor, and Auto Focus feature, adjusts focus by moving the Lens Units up and down over the Image Sensor. This helps Auto Focus speed and accuracy and also assists in reducing battery usage.

However, the camera module is fitted with a “Stopper” to limit the Lens Unit movement within the space for the Camera module. When the Lens and Stopper touch, when shaking your Galaxy, a noise may occur – however, this is normal due to the operation of the Auto Focus feature of camera, as mentioned above.

Note: The sound may differ slightly by the type of device and model.
