Is this the original pen that came with the phone?
We have to ensure that you are using the original S-Pen and not a replacement that is not a Samsung model as some replacement S-Pens on Amazon do not have the Bluetooth capabilities that are required for some functions.
At this time I would recommend an exchange for the S-Pen. If you would send me a private message with your full model code, IMEI number and the receipt for your phone I'd be more than happy to look into this for you.
