Why Does the Moisture Detected Error Appear?

Samsung Galaxy Note 10 5G has built-in moisture sensors in the USB-C port to protect against water damage. When moisture, condensation, or debris is detected, charging is blocked to prevent corrosion, short circuits, or permanent hardware damage. This is a safety feature, not a fault.

Step-by-Step Fixes for Moisture Detected Error

Step 1: Power Off & Dry Your Phone

• Turn off the device immediately to avoid short circuits.
• Unplug any charger or cable.
• Gently wipe the charging port with a soft, dry cloth or tissue.
• Place the phone in a dry, well-ventilated area for 30–60 minutes.
• Use a fan (not a hairdryer) or place near a warm (not hot) light bulb to speed drying. Source: Verizon Community Tip

Step 2: Restart with Charger Connected
