If your tablet is in a case take the tablet out of your case and retest.
There are many that use hidden magnets embedded within them either for assisting in keeping them closed, making them adjustable (stand positions) or to turn on/off the screen when opened. These tablets are sensitive to magnetic fields and the S-Pen will be affected by magnetic fields as well. Even if you don't suspect that your case has any magnets at all go ahead and remove the tablet anyway just to see.
Post your results.
