If your phone has gotten water damage, you can say "My phone has been water damaged." This is a common way to describe a phone that has been damaged by coming into contact with water. It's important to act quickly if your phone has been water damaged in order to minimize the damage and potentially save the device. You should immediately turn the phone off and remove it from the water source, then try to dry it off as much as possible. It's also a good idea to take the phone to a repair shop as soon as possible to have a professional assess the damage and determine the best course of action.
