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

Here are the primary causes of the abnormal noise for your reference:
1. The POCO F7 Pro uses a 50MP main camera with Optical Image Stabilization (OIS) and autofocus functions. And the cameras have undergone a rigorous inspection to ensure reliable performance;
2. Due to the characteristics of the OIS focus motor, there are movable components inside the motor. When the camera is not in use, these components remain in a non-fixed state, which can cause a slight noise when the phone is shaken;
3. This is a normal phenomenon and it does not negatively affect the camera's performance, so you can use it with confidence.
