Face Camera not working, Volume Up not working -Razer Phone

So don’t ask how, but my gold edition razer phone fell out of my car when I got out to check how flooded the street was and the water took the phone, I looked all night and couldn’t find it. In the morning I found it and totally expected it not to work but it did, after being submerged in water for 9 hours. xD It works just about perfectly but the volume up button isn’t working, the face facing camera isn’t even able to use it in the software, and the charging port is wack, any advice for trying to fix it or what should I do
