Samsung was granted a new patent by the U.S. Patent and Trademark Office, one that sounds like a scene from a James Bond movie. The patent published suggests that Samsung might be building a camera into the S-Pen of the Galaxy Note X this year, one with optical zooming capabilities.
The future S-Pen, as described by the patent, and illustrated by the image below, will include optical zoom lens in its body, an image sensor, and a button that can be used to control said zoom.
