A camera inside the Samsung Galaxy Note 10 S Pen makes little sense. Here's why

Back in February, patent number 10,198,649 filed with the USPTO gave us a glimpse of what the future may hold for Samsung's Galaxy Note series. Spotted by Patently Mobile, the documents describe what certainly looks like an S Pen – an S Pen with a built-in camera. The patented camera system resides in the upper portion of the stylus. Light enters through a lens placed either on the side of the S Pen or on the top of the stylus, where the clicker is currently found. Moreover, the camera is described as having optical zooming abilities. Cool stuff, right?
