Why does the camera make a noise when the POCO F7 Pro focuses?

The POCO F7 Pro uses a 50MP main camera with Optical Image Stabilization (OIS) and autofocus functions.
Here is more information as follows:
1. The phone has undergone a rigorous inspection. Due to the characteristics of the OIS focus motor, the motor contains movable components, as well as metal springs and suspension wires that enable their movement. When the OIS and autofocus are activated, the motor in the camera module moves the lens, which can produce a slight noise;
2. This is a normal phenomenon and does not negatively affect the camera's performance, so you can use it with confidence.
