What to do if the rear camera of the POCO F6 Pro is foggy?

In some scenarios, water vapor in the air can enter the inside of the POCO F6 Pro. When the external temperature of the phone drops sharply or there is a large temperature difference between the inside and outside of the phone, it will cause the water vapor inside the phone to condense, which causes fog on the lens.
This situation is similar to the fogging of eyeglass lenses when entering from a cold outdoor to a warm indoor environment in winter. It is a normal physical phenomenon. Please do not worry too much.
The fog can be eliminated naturally after leaving it for a few minutes at normal indoor temperature. You can also place your phone in a closed dry environment, such as a sealed bag with desiccant. If you need to use the camera function urgently, you can dissipate the fog quickly through methods such as cleaning the lens with your palm.
