Galaxy III was splashed with water. I pulled the battery, wiped it down and left it open over night. Seemed to work fine for 2 days after. Then I heard the speaker humming when it was on the charger. Pulled the battery again and left it open. Now I noticed condensation inside both cameras and the flash. I let it air out and the condensation disappeared after a few hours. The next day all seemed to work fine (Wi-Fi, music, calls, texting, internet, touch screen and so on) but with in hours the main speaker just quit, not even a hum, crackle or buzz. Calls, headphones, and wifi direct still sound fine.

How do I fix or replace this speaker? Is this speaker gone for good? Will one of your dry bags save it eventually? (ah, if only I knew they existed before) I'd much rather buy one of your bags and tool kit than pay that evil deductible for a replacement.

thank you in advance.
