If you have dropped your phone in water, it is important to immediately prevent further damage before attempting repairs. Remove the phone from the water, turn it off, dry it as best as you can with a soft cloth, and then proceed.
What to Do If You Drop Your Phone in Water | How to Save a Wet Cell Phone
If you drop your phone in water, a couple of things can happen. If the phone has a high IP rating against water, then it’s probably fine. You can pull it out, dry it off, and maybe use it right away. If it doesn’t have a high IP rating, or no rating at all, then dropping a phone in water can cause catastrophic damage that may not be repairable.
If a phone does not have a high IP rating, water can enter the phone and come into contact with internal electronic components. Because water is conductive, components can short out. This can cause temporary shutdown, but it can also lead to permanent damage.
If your phone has fallen into water, you need to do two things. The first and most important thing is to turn the phone off before any further damage occurs. Then you need to do everything you can to dry the phone. Never leave a phone turned on, or turn it back on, if there are still traces of water in it.
