Here’s a video from Nokia France showing off in subtle real life situations some of the features of the Nokia Lumia 1520. Note how it starts with the camera and super sensitive screen (note the gloves. Is this too subtle?).
My French is patchy so I can’t comment on what’s being said (Je suis désolé, mademoiselle Rio :/).
You can see them demo the GPS, Nokia Storyteller as well as the inbuilt wireless charging that isn’t present on the AT&T 1520.
