My girlfriend's Fairphone 3+ got wet in rain-drenched clothes. She then tried to make some calls, but first couldn't hear the other person, and later people also couldn't hear her. Then, the phone died.
We then disassembled the phone completely and laid the parts out to dry for a day.
I noticed some white corrosion on the connector for the top module, and after cleaning it with alcohol, it's visible that one of the pins is darkened.
