Why do the speaker and the microphone of the POCO X7 Pro sound low and noisy after being soaked in water?

This product supports IP68 dust and water resistance. Water will not enter the phone if soaked in water within the standard range. However, water will enter the speaker and microphone pickup holes when they are connected to the outside world. When there is a large amount of liquid water in the channel, the sound will vibrate and cause noise. Water blocking the microphone hole will also cause low sound and noise in recording and calls. It will return to normal after being left to dry for 1 to 2 days, and will not have any impact on your phone. You can use it with confidence. At the same time, it is recommended that you do not use a hair dryer to dry the speaker and microphone holes directly after water ingress, so as not to damage the speaker or microphone.
