Moisture Detected in Samsung Charging USB Port - Fix for Galaxy S8, S9, S10, A20, Note 9 & 10

Introduction

If you're experiencing the "Moisture detected" warning on your Samsung phone's USB port, even when it hasn't been near water, this tutorial will guide you through a reliable workaround. This issue is common in models like the Galaxy S8, S9, S10, A20, Note 9, and Note 10. Follow these steps to charge your phone and regain functionality.

Step 1: Prepare Your Charger

• Use a fast charger: Make sure you have the original Samsung charger or a high-quality fast USB-C charger. Avoid using non-Samsung chargers as they may not provide sufficient power.
• Consider a powerful USB-C charger: Using a high-capacity USB-C charger, like a 90-watt charger, can enhance the effectiveness of this method.

Step 2: Turn On Your Phone

• Power on your phone: Even if your battery is low, turn on your device. This action helps to bypass the moisture sensor that might be causing the warning.
• Wait for the Samsung logo: Allow your phone to display the Samsung startup screen before proceeding.

Step 3: Connect the Charger

• Plug in your charger: Once the phone is on, quickly connect your charger while the device is still booting up.
• Turn off the screen: Immediately turn off the screen to prevent any battery drain from unnecessary power usage.

Step 4: Allow Charging

• Wait a few minutes: Keep the phone screen off for a few minutes to let the charger deliver initial power to the battery.
• Observe the battery percentage: After a short wait, you should notice a small increase in battery percentage (1-3%).

Step 5: Access Your Phone

• Unlock your phone: Once you see a battery increase, you can safely enter your PIN or password.
• Use your phone normally: After the battery reaches a stable percentage (10-20%), you can start using your phone and charge it with any compatible charger.

Conclusion

This method provides a straightforward way to bypass the "Moisture detected" warning and get your Samsung phone charging again. By using a fast charger and following these steps, you can quickly regain access to your device. If you have any other tips or experiences with this issue, feel free to share them in the comments!
