Xiaomi 14 Ultra makes strange noises when shaking

This kind of shaking sound is a natural physical characteristic of high-end lenses using an OIS anti-shake structure. It is a common phenomenon in high-end anti-shake cameras on the market. This is because the anti-shake structure needs to reserve physical displacement. When shaking vigorously, the module displacement will make a sound. This is normal and will not affect the function of the phone. Please don't worry and rest assured to use.
