Dropped my iphone in water, now has white screen

Ok, so my phone fell in the toilet, and i did what everyone said to do… The whole bag of rice thing.well now i have a white screen and it comes up to my itunes, and syncs and everything, but all i can see is a white screen. Is there anything i can do to fix it without buying a new phone?

No, but ill but it for parts?

If you put it in rice for long enough like a week but if not you need stick it back in there and make sure it's properly buried
