So, I just picked up a Samsung Galaxy S3 yesterday and discovered it wouldn't mount as a drive as I'd expected, or appear as a device in iPhoto. Also the Android File Transfer wouldn't work (kept saying the phone wasn't connected) so after some trial and error I got it working and thought I'd make a video showing how to do it for others with the same problem as me. This should also work with the S4.
