While many of us are still sad over the fact that the Galaxy Note series is abandoned, at least for this year, we know that the S-Pen is still living on. The Galaxy S21 Ultra was the first smartphone to feature support for the S-Pen, and we know that the Galaxy Z Fold 3 will also support the magic stylus. However, a recent report suggests that there might be more in tow.

FCC has just cleared the unreleased S-Pen Pro. It carries the model number EJ-P5450; this pen was originally announced back in January 2021 alongside the Galaxy S21 family, but Samsung did say that it will be released later this year.
