The S Pen that comes with the Samsung Galaxy Note series really sets it apart and is a terrific tool for users that want to get more features out of their smartphone, as well as tackle a lot of productivity limitations. It is not merely a stylus but is expected to offer some unique features that are only available for the Galaxy Note 9. A well-known tipster has shared some good news on Twitter, signifying that while the design of the Galaxy Note 9 and Galaxy Note 8 is going to be similar, this exclusive feature will be worth waiting for.

Earlier this year, it was rumored that the S Pen may support Bluetooth connectivity which may, or may not give the accessory the option to act as a wireless speaker, assuming Samsung incorporates such a feature. If this goes through, this will require more energy which means that this year’s S Pen might be thicker than the previous generations and might need its own dedicated battery.
