How to save phone wet with water?
After you remove the phone from the water, you should unplug it if it is left on, and remove the battery if possible.
Take a cloth and wipe the phone thoroughly to remove excess water. Even though you wiped it, the moisture remained inside the electronic parts of the mobile phone.
Take a basket with a lid, or a regular plastic bag. Fill it with rice, put the cell phone inside and close it tightly.
The rice will get the moisture out of the phone and hopefully your phone will work again. Leave the phone in the rice for 24 hours so that the moisture is completely removed.
