Galaxy Note 9: How to fix S Pen issue?

Reason: Usage of S Pen at sharp angles on specific areas

Solution: if you use the 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 your S Pen upright and use S Pen with more force. 

Additionally if you use the S Pen at sharp angles anywhere on the screen, the device may not recognize the S Pen actions. So Please do not use S pen at sharp angles.
