Who I have the same questioned this topic

My phone got seriously wet last Thursday.  I've had it in a bowl of rice ever since then (four days).  I thought this weekend that it was coming back, because I could get a picture, even though it was flickering.  I put it back in the rice, but now when I check on it, I am getting no picture at all, just a snowy screen.  Is there anything else I can do, or is my phone shot?
