Is it normal to hear a mechanical sound when the lens cover opens or closes?

The sound you hear during the lens cover operation is due to mechanical movement. The mechanism is designed for durability and safety, so the noise when opening or closing the lens cover is part of the operation.

If you are sensitive to this sound, you can turn off the auto lens cover function by following these steps:

Press the Settings button on the remote, navigate to All Settings > System > Power & Energy > Auto Lens Cover, select Always ON.
