The Xiaomi 15 Ultra features a multi-lens camera system, and when switching between lenses, the camera module undergoes a precise adjustment to align the lenses properly. This process involves the movement of the lens elements within the camera module, and as part of this mechanism, the camera module is controlled to return to its center position.
The sound you hear during this lens-switching process is completely normal and is simply a result of the internal movements required to change between different lenses. It’s important to note that this sound is not indicative of a malfunction; it’s simply the noise of the mechanical components working as they should to ensure the correct lens is in place for your shot.
This process is a standard feature of phones with advanced camera systems that have multiple lenses with adjustable mechanisms for optimal focus and image quality. Rest assured, this sound will not affect the photo function or the overall performance of the camera.
