Samsung hasn't been shy about hinting that the Galaxy Note 9 launch will focus heavily on the S Pen. Now, however, we have a better idea of what that means. An FCC filing for the Note 9's S Pen has revealed that it'll include Bluetooth, suggesting remote control features. The documents unsurprisingly don't say what those features are, but leaker Ice Universe had previously claimed that the stylus could control music playback and timers. We wouldn't expect anything sophisticated (it's a one-button device without a screen), but it could provide value even if you only rarely intend to draw.
