Does Magnetic Materials Affect S Pen action?

If you attach a magnetic case or cover to Samsung Galaxy Note8, Galaxy Note8 may not recognize the S Pen actions and the S Pen may not work properly. 

Also, if you use S Pen at sharp angles on specific areas affected from magnetic force like around Front Camera, S Pen may not work due to magnetic force. At that time we recommend to put S Pen upright and use it with more force. 

Additionally, if you use S Pen at sharp angles anywhere on the screen, Samsung Galaxy Note8 may not recognize the S Pen actions.
