Troubleshooting USB Debugging Issues on Samsung S20

If you’re facing issues with USB debugging on your Samsung S20, don’t worry, you’re not alone. USB debugging is a powerful feature that allows for advanced troubleshooting and development tasks, but it can sometimes encounter hiccups. Here are some common issues you may encounter and troubleshooting steps to resolve them.

1. USB Debugging Not Detected: If your Samsung S20 is not being detected when USB debugging is enabled, there are a few things you can try. First, ensure that you have enabled USB debugging in the developer options. Go to Settings > About Phone > Software Information > Build Number and tap on it seven times to unlock the developer options. Then, go to Settings > Developer Options > USB Debugging and make sure it is enabled.

If USB debugging is enabled and your device is still not detected, try using a different USB cable or a different USB port on your computer. Sometimes, faulty cables or ports can cause connectivity issues. You can also try restarting both your phone and computer to refresh the USB connection.

2. Driver Issues: Another common problem is missing or outdated drivers. To resolve this, make sure you have the latest Samsung USB drivers installed on your computer. You can download them from the Samsung website or use a third-party driver updating tool. Once the drivers are installed, reconnect your phone to the computer and see if the USB debugging is detected.

3. Unauthorized Device: Sometimes, when you connect your Samsung S20 to a computer, you may see a pop-up message stating that the device is unauthorized. This can occur due to security settings on your phone. To fix this, disconnect your phone from the computer and go to Settings > Developer Options > Revoke USB Debugging Authorizations. Then, reconnect your phone and authorize the computer when the pop-up appears.

4. USB Debugging Greyed Out: If you find that the USB Debugging option is greyed out on your Samsung S20, it means that you do not have sufficient permissions to enable it. This can happen if your phone is locked or if you have a work profile or managed device setup. To enable USB debugging in such cases, you may need to contact your device administrator or unlock your phone with the appropriate credentials.

5. Unknown Sources and Verify Apps: Sometimes, USB debugging may not work if you have certain security settings enabled on your phone. Ensure that the “Unknown Sources” option is enabled under Settings > Security, as this allows the installation of apps from outside the Play Store. Additionally, make sure that the “Verify Apps” option is disabled, as it can cause conflicts with USB debugging.

6. Verify USB Connection Mode: Lastly, ensure that your phone is set to the correct USB connection mode. While debugging, the recommended mode is “File transfer” or “MTP. To check this, connect your phone to the computer via USB cable, swipe down the notification panel, and tap on the USB connection mode. Select “File transfer” if it’s not already selected.
