My phone samsung galaxy s22 ultra is frequently showing waring regarding moisture presence in charging port. Service center is saying charging port has to be replaced. Also my phone has been not in contact with any kind of moisture or dust. I think this is manufacturing defect for many devices.
As per your query, we would request you to kindly perform the following steps to resolve your issue.
Kindly try to charge with another charger and use the genuine Samsung charger.
Clear your USB cache: Settings > Apps > Tap the Filter and Sort icon > Move the switch to the right to enable Show system apps > Tap OK > USB settings > Tap Storage > Tap Clear cache.
Unplug your device from the charger, then wipe with a dry cloth or gently shake your device (5-10 times) with the port facing downwards to release any excess moisture. Place your phone on a cloth in a well-ventilated area, or dry it with a fan.
Note: Excessive force or shaking may cause damage to your phone. When shaking your device, be gentle. You may get a Moisture-detected error even if your phone did not come into contact with water. Exposure to environments with high humidity may cause this. Try drying your device, and if your charging port is completely dry, restart your phone. Check that your device is placed directly in the center of the pad, without any obstructions in the way.
In case the issue still occurs kindly visit the service center for a physical inspection of your device. You can locate your nearest service center with this given link: https://www.samsung.com/in/support/service-center/
