Default Should the s-pen have flexible or stiff tip?

I just purchased note 8.0 which is really great, but one thing is starting to annoy me (a little). That's the tip of the s-pen which is flexible (it moves on the sides a milimetr or two) and also if I press it against a surface the tip is pushed a 1/2 mm inside the s-pen.

I would much more preffer a stiff tip, like my pen's, and I was wondering if it's just a faulty s-pen I got, or if it's by design and all you have the same kind of s-pen tip?

If so... is there any way I can make the tip to be still like say... a pencil tip? What would be important is to have it reversible, so gluing the tip to the case is rather out of the question.

Any help from someone who was looking for the same thing as me?
