Dropped my iPhone 6 in water and it seems fine but IIm worried?

My cat knocked in into water and IIm not sure how long it was in there before I noticed, but when I found it I took it out right away and dried it with a towel, I didn't see any water inside and it seems to work fine but it wasn't in a case so there must be water damage. I don't know if its actually fine or its randomly gonna stop working SOS

Just put it in a bag of rice for a day and it will be fine.
