Why does the zoom ring on the Xiaomi 17 Ultra Leica Version make noise when rotating?

Question

Accepted Answer

If you hear a slight noise when rotating the zoom ring on the Xiaomi 17 Ultra Leica Version, please refer to the following explanation:
1. The Xiaomi 17 Ultra Leica Version features a precision mechanical zoom ring designed to simulate the tactile feedback of a professional camera lens.
2. During rotation, the zoom ring generates rolling and sliding friction with multiple internal mechanical components. This interaction creates the damping sensation that provides controlled and stable adjustment.
3. The slight sound produced during this process is a normal result of mechanical movement and precision structure operation. It does not indicate a defect or abnormal condition.
4. This sound will not affect zoom performance, shooting experience, or the lifespan of the device.
