Dropped fairphone into water

So, I dropped my fairphone into a catfish tank at the aquarium (small child involved!). It was fished out within about 30 seconds, had switched itself off, I took it apart, dried out the pieces, and put it into a box of rice for 48 hours when I got home. It looks dry now and I have charged it but the phone is completely dead. What next?
