There is a rattling noise when i shake my device

Last Update date : 2017.05.23

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



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

However, Camera module is fitted with a “Stopper” part to limit 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 device types and model.
