Problem 7: Samsung Galaxy S9 Audio Problems due to Wet Speaker

The Samsung Galaxy S9 is an IP68 rated smartphone and due to that, users can use their smartphone in wet environments.

This happens when the water gets into the speaker grill of your device and muffles the speaker.

Solution: To address this issue, Samsung has a waterproof film right in front of the speaker that stops water from permanently damaging your device’s speaker. So if you are facing any audio problems from the loudspeaker, it is highly recommended that you let the speaker dry for some time. And after a while, you’ll see that the speaker of your device has been fixed as all of the water would have evaporated.
