It's possible that the capacitor in the S-pen is no longer holding a charge after 5ish years, meaning it can't power the Bluetooth connection anymore, so all the pen can do is write and draw now. I'd probably try to get a replacement note9 S-pen (not one of the newer ones as they have different dimensions and may not fit in the slot correctly) and see if that connects.
I don't believe there was a note s9. I believe it's either a note 9, or a Galaxy s9. Either way, the phone is over 5 years old and no longer getting Android updates. Could it be nearing its end of life causing it to malfunction?
