Why is my phone cannot turn on

Once you’ve gotten as much water as possible out, take it apart as far as you can (remove the battery if you can and leave battery cover off). Silica gel or instant rice may be helpful, but only if you use a large quantity I would suggest at least 4 cups, and a container that’s at least 1-2 quarts. Don’t use conventional white rice as this isn't as effective. And if you don’t have silica gel or instant rice, don’t worry. Leaving your phone in open air, (perhaps with a fan for better air circulation) works just as well.
