On the smaller phone (iPhone 6) the lens is 50mm from the far (button) edge of the phone and protrudes 0.8mm. The phone is 7mm thick.
Thus there is a triangle formed on the top of the phone which is 0.8mm tall and 50mm base. Now, if you make the triangle 7.8mm tall you form a triangle with the front plane of the phone, a triangle with a base (7.8/0.8)*50 of 487mm.
So if you take the picture from less than 487mm away (half a meter) you can take a picture which doesn't show the camera and doesn't show the face of the phone (thus is "edge on") without using any photoshop trickery. The phone body will simply block the camera from view.
And that's surely what Apple did. It's not hard to do.
Also note: you don't have one, troll. It doesn't come out for a couple more days.
