Had the iphone in a ziplock while riding a wave-runner and it got a little wet. The camera light will not turn off but the rest of the phone worked. Tried all the suggestions here but none of them worked and I was ready to bring it to the Apple store to replace the camera module. However, after keeping the phone in a combination of rice and oats for 24 hours, the light went off. I guess the inside just needed to dry. Glad I was patient. Good luck!
