Xboxclips.com is the easiest way for me.....just go to that site and enter your GT and anything recorded/screenshoot will be available if it finish Dling on the Xbox....
I use the xbox phone app and when taking photo I go in photo mode in the drone mode, then I puss that button with two squares so tools going away, then not playstation button, but Xbox button then triangle then in a few moment your photos are for pickup at the app
