I realise your solution did work for you, and it did work for a lot of people on “the internet” in general.
But everybody coming for advice after your Fairphone got wet, please, do not use rice as a desiccant.
Dry rice is not a good desiccant. It might even bring you more trouble. Rice dust (i.e., starch) might get into your phone, which might be detrimental to your circuit boards (not to speak of your camera). I know that “the internet” advises you to use rice, but please, trust me on this.
Or better, if you’ve got time on your hands, perform experiments with rice in a sealed box against silica in a sealed box against drying at ambient levels of humidity, using something soaked in a defined amount of water, and over a defined time. Don’t use your phone, though. 
For the record, I have plenty of experience in drying things. With silica. Including electronics, like my old and trusted DLSR. And I also sometimes had to use rice, because I could not regenerate my silica at the time. I strongly advise against it. Seriously.
