The Galaxy Note 9 is here, and like every Galaxy Note device before it, one of the highlights of the Note 9 is the thing that separates it from most other smartphones: the S Pen stylus.
This time around, Samsung is upgrading the S Pen in a big way: it’s adding Bluetooth Low Energy, turning the stylus from a mere note-taking accessory into a full-fledged remote control for your phone.
