So I was trying to listen to a really quiet video on youtube after i had shaved, and I got shaving cream on my phone's Pelican case. Thinking my Galaxy S6 was supposed to be water resistant, I decided it'd be a good idea to go ahead and put it under the faucet to get the shaving cream off the phone with water. It worked, but apparently a small amount of water sprinked into the speaker area and now my speaker is all screwed up. The sound coming out of it is extremely scratchy, like ear rape, and I don't know if this is just due to water in the speaker or permanent damage to the speaker by the water exposure.
What can I do to help fix this, short of having to get a new phone?
I already tried letting the phone stand upright and dry out for several hours, but that didn't help. In fact now the speaker quality seems even worse!
