AirDrop Files on an iOS Device Go To…
When you opt to receive files via AirDrop on your iOS device, they can go to various locations depending on the type of file being received. While this might sound like a pain in the butt, it actually is easy to remember which file goes where.
AirDropped images, videos, and movies will be accessible via your device’s Camera Roll and the Photos app. When receiving a file that will go to the Camera Roll, (remember, that’s videos, images, movies, and similar media files), it might not look like the transfer worked properly, as there’s no confirmation message, but look on your device’s Camera Roll and you’ll likely find the file.
Look for this screen on your iPhone 6 and tap Videos.
