"Chopped" may be that you're using the wide-angle lens setting and/or that you're occupying space in the frame that's near the left or right edge. Lenses--especially wide-angle ones--distort in a manner that widens objects in the extremities of the frame. Try being more centered in the frame if that's what you suspect is happening. Selfies suffer especially, as the camera-to-subject distance is short (arms'-length) and distortion is unavoidable unless you can post-process and correct for distortion. Better is to have the camera farther away from you, but that's hard with selfies.
