Step 6: Try Different USB Cable and Port

Sometimes, there could be the problem with your USB cable itself. As you know, all USB cables go through endless flexing and curling states. Due to this, your USB cable might get damaged internally. Many users purchase cheap cables that only support charging but not data transfer, which causes Android phone not showing in ADB problems.

I recommend you to try connecting your phone with another authentic USB cable rather than cheap alternatives and check if it solves your problem. Also, try different USB ports on your computer, preferably USB 2.0 ports instead of USB 3.0, as some older Android devices have compatibility issues with USB 3.0 controllers. If your phone still won't connect, read how to fix connection problems.

Step 7: Enable ADB Over WiFi (Wireless Debugging)

If USB connection continues to fail, you can try ADB over WiFi connection as an alternative method. This is especially useful when dealing with faulty USB ports or cables. Modern Android versions support wireless debugging natively.

To set up wireless ADB:

1. First, connect your device via USB temporarily and run: adb tcpip 5555
2. Disconnect the USB cable from your device.
3. Find your phone's IP address from Settings > About Phone > Status.
4. Run the command: adb connect [your-phone-ip]:5555
5. Your device should now connect wirelessly for ADB commands.

This method bypasses USB connection issues entirely. Make sure both devices are on the same WiFi network for this to work properly. For more Android optimization tips, check how to fix common Android errors.

Step 8: Check Device Authorization and RSA Keys

When you first connect an Android device via ADB, it prompts for authorization with an RSA key fingerprint. If you accidentally clicked "Cancel" or "Always allow from this computer" was not selected, you might face ADB authorization failed fix issues.

To resolve this:

1. Disconnect and reconnect your USB cable.
2. Check your phone screen for the "Allow USB Debugging?" prompt.
3. Check the box "Always allow from this computer" before tapping OK.
4. If the prompt does not appear, go to Developer Options and tap "Revoke USB debugging authorizations".
5. Reconnect the device to trigger the authorization dialog again.

This step is crucial for security and functionality. Without proper authorization, ADB will see the device but cannot execute commands. You might also want to fix other Android process errors.

Step 9: Install Google USB Driver Manually

For users running Android Studio or latest SDK tools, manually installing the Google USB driver ensures compatibility with all Nexus and Pixel devices, plus most mainstream Android phones.

Steps to install:

1. Open Android Studio and go to SDK Manager.
2. Navigate to SDK Tools tab.
3. Check "Google USB Driver" and click Apply to download.
4. Once downloaded, go to Device Manager as explained in Step 3.
5. Point the driver update to the downloaded Google USB Driver location.
