Camera on my iPhone keeps coming up black?

I was at a concert last night and it started to rain, I literally had my phone out for 2 minutes but later when it stopped raining I took my phone out to take a picture both cameras were steamed up! Whenever I got onto the camera or snap chat the the screen just comes up black and it doesn't let me take a picture. I put it in rice for 8 hours in the hot press and the steam is gone but the camera still won't work! I have no idea what to do but I need to fix it as soon as possible! Why suggestions on how to fix this problem?

I think some water insert your phone chip and not connect with your camera. You can go to your near by customer care and fix your problem.
