The Galaxy Z Fold 3 will support the S Pen Pro, according to FCC filings
After many teases, it seems as if a Samsung foldable is finally going to get support for an S Pen stylus. FCC filings for the S Pen Pro, a bigger version of the S Pen with Bluetooth connectivity that Samsung announced in January, have been made public, and one document (PDF) reveals that the upcoming stylus will work with the unannounced Galaxy Z Fold 3 (which is presumably the next device in the Z Fold lineup).
And it’s not just the Z Fold 3 — the stylus, which doesn’t have a release date but is set to hit this year, will apparently support the S21 Ultra, the Note 20 lineup, and more. You can see the full list of devices that the S Pen Pro will support in this image from the filing:
