We've detected moisture or foreign material in your charging/USB port.
Check your charging/USB port for any foreign material such as dust or debris. To prevent damage to your phone, don't plug anything in until the charging port is clean, the moisture is gone, and the notification is cleared.
To dry the port, shake out any moisture, then wait for it to dry, which could take several hours. You can speed up drying by pointing a fan or dryer (cool air only) at the port.
