When you download the DJI Fly app on your phone or tablet, after you fly and take photos and video, you can connect directly to the drone using the app and download the files directly to your mobile device. You don't need to turn on the controller for this to work since it connects via wifi to your mobile device. You can also take the micro SD Card out and plug it into your device to see the photo and video, or plug your USB-C cable directly to your computer to download files that was as well.
