According to recent Samsung patents, the next Galaxy Note may integrate a S Pen that can auto-eject for the user via magnets and polarization. In addition, a separate Samsung patent as reported by Patentlymobile.com reveals potential smartphones with "folding displays" and special hinges. The word "folding" is stressed here as opposed to "curved" or "bendable" displays as seen on the already released Galaxy S6 Edge. The single screen could be folded into a clamshell design reminiscent to a Nintendo DS.
The same patent also details a multi-functional camera pen called "The Photographer" that can take pictures and transfer them wirelessly to a tablet or smartphone for direct editing and sharing. Other special features include OCR (optical character recognition) for scanning images and extracting characters.
It's no secret that Samsung has been putting much R&D effort into transparent, flexible, rollable, and foldable displays. Vice Chairman and CEO Oh-Hyn Kwon announced in 2013 that devices with foldable displays could come as early as 2015.
