• Enable the USB Debugging Mode on the Samsung Galaxy S7 Edge device by tapping on the Settings > Developer Options > USB Debugging Mode.
• If your Galaxy S7 Edge does not have the Developer Options available from the settings, it means it needs unlocking.

You can head back to the settings to find your Developer Options menu as soon as you get that message.
