Why is the lens fogging up on the Xiaomi 17 Ultra?

If you observe temporary condensation on the camera lens of the Xiaomi 17 Ultra, please refer to the following explanation:
1. The device supports IP68 protection, but its internal structure is not vacuum-sealed. Limited air exchange occurs between the inside and outside environment.
2. When the ambient temperature changes rapidly, such as moving from a cold outdoor environment to a warm indoor space, moisture in the air can condense on cooler surfaces, causing temporary fogging.
3. This is a common physical phenomenon similar to eyeglasses fogging in winter. Under normal room temperature conditions, the condensation will naturally dissipate within a few minutes.
4. If immediate use is required, gently warming the lens area with your palm can help accelerate moisture evaporation.
5. If fogging persists for an extended period, please contact an official service center for further inspection.
