If you have an electronic device submerged in water , First remove any power source, if it is an unsealed battery discard it. Rinse in de-ionised or distilled water then dry it.

Damage done depends upon type of water and electrolyte content and weather a power source was available, and time of exposure

Drying can be done with rice according to the telly could be done with rice.

20 years ago we used something called Fomblin which later turned out to be a bad idea for water displacement.

Better to use elevated temperatures and a dessiccant such as 3A zeolite or preferably a vacuum chamber. Early cell phones had LCD displays which had no edge seal and could me easily damaged.. Other components such as electrolytic capacitors should be replaced.  

EDIT: Older electrolytics sometimes had a vent (wire type) and microphones had a protective cover during manufacture , these had to be replaced as well. I do not know the current recommendations for more modern devices. Water displacement used to be recommended but i do not know what is the best for this these days.
