Why does the Xiaomi 17 Ultra make a strange noise when shaken?

Question

Accepted Answer

If you hear a slight or strange noise when shaking the Xiaomi 17 Ultra, please refer to the following explanation:
1. The Xiaomi 17 Ultra is equipped with an advanced camera module that features a built-in optical image stabilization (OIS) system and a movable optical structure. When the device is shaken, internal components such as the lens group and stabilization module can move slightly within their designed range, which can produce a subtle sound.
2. This is a normal physical characteristic of precision optical hardware. Similar sounds can also be heard in professional cameras and other imaging devices that use comparable stabilization technology.
3. OIS is built into the camera system and works automatically. There is no manual switch to turn it on or off. The stabilization components remain in a ready state to ensure fast response and stable image capture.
4. The sound does not indicate any defect or loose parts. It will not affect camera performance, image quality, or the overall lifespan of the device.
