An official blog post says you can buy a Bluetooth S Pen for the Galaxy S25 Ultra. This leaves us very confused.

The Galaxy S25 Ultra's S Pen silo carries hardware to charge a stylus, but the new Bluetooth-less S Pen doesn't need it.

Samsung has since clarified that Bluetooth support for the S Pen is, in fact, gone. According to Samsung, the blog post was made in error, and the Galaxy S25 Ultra will not offer any Bluetooth stylus features, regardless of which S Pen you have.
