Why Does the Moisture Detected Error Appear?

Samsung phones like the Note 10 5G come with moisture sensors in the USB-C port to protect your device from water damage. If moisture or debris is detected in the charging port, charging will be temporarily blocked to prevent corrosion and other issues (Samsung Support).

Step 1: Power Off & Dry Your Phone

  • Turn off your device to prevent short circuits.
  • Unplug the charger.
  • Use a soft dry cloth to wipe the charging port gently.
  • Leave your phone in a dry and well-ventilated area.
  • You can also place it near a warm (not hot) light bulb or use a fan to speed up drying (Verizon Community Users’ Tip).

Step 2: Restart with Charger Connected

  • Turn off your phone.
  • Plug in your charger.
  • Turn the phone back on while still connected.
  • This “resets” the moisture detection and often clears the warning (iFixit Guide).

Step 3: Inspect and Clean the Charging Port

  • Use a flashlight to check the USB-C port for lint or debris.
  • Blow gently or use a soft brush to clear out any foreign objects.
  • Avoid inserting metal or sharp tools which can damage the contacts (Samsung Official Guide).

Step 4: Disable Fast Charging (Temporary Workaround)

  • Go to Settings > Battery and device care > Battery > More battery settings.
  • Turn off “Fast charging” or “Super fast charging.”
  • Charge your device with regular charging until issue clears.
  • Some users report this stops the moisture error temporarily (Reddit User Reports).

Step 5: Software Updates & Cache Clearance

  • Make sure your Note 10 5G software is up to date: Settings > Software update > Download and install.
  • Go to Settings > Apps > USB settings or relevant port app > Clear cache and storage.
  • Restart your phone and try charging again (Samsung Community).

Step 6: Visit a Samsung Service Center

If the error persists after drying and cleaning, the moisture sensor or port hardware might be faulty. Visit a Samsung authorized repair center for diagnostics and repair (Samsung support locator).

Tips to Avoid Moisture Detection Errors

  • Avoid charging your phone in humid or damp environments.
  • Always use genuine or Samsung-certified chargers and cables.
  • Keep charging ports covered or protected from dust and liquid exposure.
