Water damage - black screen

I somehow knocked over a glass of water during the night, my iPhone was right next to it and ended up lying in the water for sometime (not sure how long). When I realised I checked my phone, it didn't seem that wet (just a little bit on the back) so I didn't worry about it just put it down. When I came to it later it had turned itself off, I could see water droplets in the camera lens so I put it in a box of rice for a couple of days, tried it again and nothing. I thought it was a gonna and for some reason I put it on to charge, the next day siri started talking to me (I hadn't actually touched it so a little surprised!) I have now managed to unlock it, get siri to send messages and read out messages. Everything seems to be fine other than the screen has nothing on it. I have some photos which are not backed up and would really like them. Is there anyway I can get them? (can't get then downloaded to iCloud as I can't access settings on my phone to allow this)
