Troubleshooting Common Scrcpy Issues

Even with its impressive features, scrcpy users occasionally encounter issues that can be frustrating if you’re new to the tool. Don’t worry—most problems are easy to fix with the right guidance. Let’s dive into some of the most common issues and how to solve them.

1. “adb: no devices/emulators found”

This is one of the most frequent errors users encounter when their device isn’t recognised by scrcpy.

Possible Causes:

• USB debugging isn’t enabled.
• Faulty or incompatible USB cable.
• Missing or outdated ADB drivers.

Solution:

1. Ensure USB debugging is enabled on your device. Go to Settings > Developer Options > USB Debugging and turn it on.
2. Use a high-quality USB cable and ensure it’s connected securely.
3. Update or reinstall ADB drivers:
   • On Windows, install the Universal ADB Drivers.
   • On macOS/Linux, ensure adb is installed and updated via your package manager.
4. Verify your device is detected by running:

adb devices

If it doesn’t show up, restart the ADB server:

adb kill-server
adb start-server

2. “No connection could be made because the target machine actively refused it (10061)”

This error occurs when scrcpy cannot establish a connection with the device, typically during wireless setup.

Solution:

1. Ensure the device and computer are on the same Wi-Fi network.
2. Verify that you’ve enabled adb tcpip mode on your device:

adb tcpip 5555
adb connect [Your_Device_IP]:5555

Disable any firewalls or antivirus software that might block the connection.

3. Black Screen or No Video Output

Sometimes, scrcpy launches but displays a black screen instead of your device’s output.

Possible Causes:

• Outdated Android drivers or scrcpy version.
• Conflicting video codecs.

Solution:

1. Ensure your Android device has Screen Mirroring permissions.
2. Update scrcpy to the latest version.
3. Try forcing a specific video codec:

scrcpy –video-codec=h264

or

scrcpy –video-codec=h265

4. “adb server version (41) doesn’t match this client (39); killing…”

This error occurs when there’s a mismatch between your ADB version and scrcpy.

Solution:

1. Update your ADB installation to the latest version.
2. Restart the ADB server:

adb kill-server
adb start-server

5. “Device Unauthorized”

If your device appears as unauthorized, you won’t be able to control it via scrcpy.

Solution:

1. Disconnect and reconnect your device to your computer.
2. Look for a prompt on your device asking you to authorise the connection.
3. Check “Always allow from this computer” and tap Allow.

6. Lagging or Stuttering Video

While scrcpy is designed for low latency, network or hardware limitations can cause lag.

Solution:

Reduce the resolution:

scrcpy –max-size=1280

Lower the frame rate:

scrcpy –max-fps=30

Use a USB connection instead of wireless for smoother performance.

7. Audio Not Working

If audio isn’t forwarded, ensure your device meets the requirements.

Solution:

• Audio forwarding works only on Android 11+. If you’re on a lower version, this feature isn’t supported.
• Run scrcpy with the --audio option:

scrcpy –audio

8. Input Permissions Error (INJECT_EVENTS Permission)

On some devices, particularly Xiaomi, you might see this error when using your keyboard or mouse.

Solution:

1. Enable USB Debugging (Security Settings) in Developer Options.
2. Reboot your device after enabling this option.

9. Scrcpy Won’t Launch

If scrcpy fails to start or crashes on launch, check for missing dependencies.

Solution:

• On Linux/macOS, ensure FFmpeg and SDL2 are installed.
• Re-download scrcpy from its official GitHub page to ensure no files are corrupted.

By addressing these common issues, you’ll be back to enjoying scrcpy in no time. If you’re still facing problems, check the official FAQ or reach out to the community on Reddit.
