When your phone encounters a whole lot of water, or just a little bit in the right places, the following can occur:
1) loudspeaker/earspeaker volume gets cut drastically, but will get loud once again around 30 minutes later.
2) people say they can't hear you well or sound muffled over the phone, just blow into the microphone holes.
3) headphone connection thing popping up, just blow into the headphone jack.
4) water can still breach the inside of the back cover, but will never breach the rubber seal. Always make sure to dry off excess water.
There may be more on this list, but this is all that I have encountered or know can happen. Feel free to post other things you have experienced and I can add them to the list for people to easily see. We don't want people getting their phones wet and thinking it broke just because a speaker cut its volume to protect itself.
