USB Debugging is a way for an Android device to communicate with the Android SDK (Software Developer Kit) over a USB connection.
Enable USB debugging is the necessary step to set up Non-Root to use AirMirror (Remote control) feature.
The steps to enable USB debugging depend on the version of Android running on the target device.
- Android 4.1: Setting > Developer options > Enable USB debugging.
- Android 4.2+: Setting > About phone > Tap Build number for 7 times to enable Developer options. Then go to Developer options to enable USB debugging.
If you are running Android 4.2.2 or later, you may see the following dialog when you connect your device to your PC, kindly checked ‘Always allow debugging from this computer’ and click OK to allow USB debugging on your PC.
If you accidentally click Cancel, disconnect your device from your PC and connect it back to make the dialog show up again on your device.
