Why does the Redmi Note 13 Pro+ 5G have issues with playing sound after being submerged in water?

The Redmi Note 13 Pro+ 5G supports IP68 dust and water resistance, meaning it can withstand water immersion within the standard range without allowing water to enter the phone. However, water can enter through the speaker and microphone holes, which are connected to the outside. When water is present in these channels, external sounds can cause the droplets to vibrate, leading to noise. Additionally, water blocking the microphone hole can cause low sound and noise during recording and calls.
The phone should return to normal after air-drying for 1 to 2 days, and the sound quality will not be affected. Your phone remains functional and can be used with confidence. It is not recommended to use a hair dryer to dry the speaker and microphone holes directly, as this can damage the components.
