Vlad, just like any other device that has a water immersion, it needs to be cleaned properly. Disassemble your Nokia, then clean every part with a high grade (90%+) isopropyl alcohol. Do not forget to clean all the cable connectors. While you clean, do a visual inspection and check for any missing, broken components. After you cleaned the Nokia, replace the battery. Cleaning the phone is a must to prevent corrosion damage. After you clean it and replace the battery, re-evaluate. Water damage is the toughest to diagnose since it is hard to determine which part has failed.
