IPhone 4S exposed to water

Okay so I have a lifeproof waterproof case.while sitting in the hot tub the little clip came open for a few seconds letting water into my iPhone.

You are supposed to turn the phone off when this happens, but my touch screen isn't useable and my lock button was already broken.

Is there anything i can do?

The best thing you can try is letting it sit in raw rice for a few days, hope it works out!

Insurance won't cover it because there's something inside the phone that tells them if it was soaked in water, or if it was just a little moist. It could be toast. I would try the rice thing (nothing to lose!)
