After a lot of use, the pen tips need to be replaced. They get worn down over time. The tablet came with 3 or 4 extra pen tips and this metal circley thing that you can use to remove your current pen tip and insert a new one. It should work once you replace it!
My tablet has been working fine and now for reasons unknown to me the pen part is not being recognized by the tablet. It still works by touch but not with the pen. Has anyone else run into this problem? And if so how did you fix it???
