There are websites with tips on how to dry out your phone and hopefully salvaging it without losing your information and having to spend money on another phone. Local 6 followed some of these methods to see what works.
Take the phone out of the water as soon as possible. The plastic covers on cell phones are fairly tight, but water can enter the phone in a short period of time, perhaps only 20 seconds or less. Grab your phone quickly! Don't switch the phone on, as this can cause it to short circuit – if it has been in water, assume it needs drying immediately whether or not it is working.
Remove the covers & SIM card. First, remove the battery and the SIM card. Dry the battery and SIM card's contacts using the tissue.
Then remove the phone's covers. These may be easily removable if your phone can take different ‘skins’. Otherwise, you should be able to pop the covers off or lever them off with a screwdriver.
Put the phone in a bowl of dry rice. Many people have had success with this one, and it makes sense because uncooked rice can absorb a lot of water. For most cell phone models, you won’t have to worry about the rice grains getting inside of the phone. The following video provides a quick one-minute demonstration of how this is done.
Heat Vents. Another option is to keep the cell phone on heat vents of computers or televisions. The heat emitted from these vents is most appropriate for drying out the moisture. But you also need to see to it that you do not keep the cell phone on the vents for a substantial period of time, as extra heat can do a lot of damage to the inner parts. Never experiment to dry out a cell phone in the oven.
Play the waiting game. Make sure that you don't switch your phone back on until you are certain it has completely dried out, or you could cause damage. Most importantly, don't panic, most phones survive getting wet and as long as you’re dry out your cell phone quickly and effectively, you should have nothing to worry about.
Test the Phone. Turn it on and hope for the best. If it still doesn’t work you may need to disassemble your phone. Leave device 1-3 days to completely dry in a moderate temperature, low humidity environment. If you're lucky, after this dry out time, you'll be able to power up your device and invest in a waterproof case and an extended warranty.
