A:AnswerI believe it would work for writing only, but it may not fit on the phone and this Pen need to be charge. It work on my Galaxy Tab S3 Tablet. I believe you should buy the original pen for the Note 20.
A:AnswerThe only time it needs to be connected is when you put it into the pen socket on galaxy note 10 to rest it when the note 10 and pen lose contact ith each other or at end of session.
