Check any external ports (charging port, headphone jack, SIM card slot, etc.) for corrosion as well. These may have to be cleaned out with alcohol and a Anti Static Brush, or replaced if cleaning is not practical.

Pay special attention to cable ends, battery contacts, connectors, pins, and fuses, as these parts are prone to corrosion and can easily cause the phone to malfunction.

Test all the buttons and features (such as the microphone, speakers, wireless connectivity, iPhone camera, etc.).

If you can't find the source of the problem, it's possible that components under the EMI shields have been damaged. De-solder the shields and clean the board with an Ultrasonic Cleaning Machine.
