Samsung Galaxy S6 got wet, but didn't fall completely into the pool, help?

so i went to a friend's pool today and was (stupidly) holding my phone as a was getting onto one of those big raft floats and water accidentally got in and my phone got wet, but it didn't fall into the water. So i checked to see if it was still working and it was so i just dried it off and left it alone. So once i went back home, my phone shut itself off and when i turned it on, it kept saying that it was overheating so i shut it off again. I opened up the sim card tray to check the ldi and it was white, so it's not water damaged i don't think.

but i'm afraid to turn it back on, and the touchpads aren't working either when it was on, any tips on what i should do? (also the front camera is foggy, will this go away by itself?)
