"Dropped Phone in Water"に関する回答Water damage can cause all kinds of problems, some of which may not be fixable without a board replacement. Assuming your device doesn’t have permanent damage, the important thing is to try and get all the water out of the phone. If you haven’t already done so, turn the phone off and put it in a bag of rice (or silica gel packets, if you have them) for a day or two. This should help to draw any moisture out of the phone. Simply leaving it out in the air or trying to shake out the water will not generally work to remove all of the moisture, and it doesn’t take very much to short out a circuit trace. This may not be enough to get everything working, but it should definitely be one of the first things you try whenever you have a water-damaged electronic device. You should seriously consider having a repair shop look at it, even if it starts working after it is dried out. Corrosion on the circuits is progressive and will eventually kill the board if it is not properly cleaned and the damage repaired.
