I assumed under Settings > Controls > S Pen, all of your settings are not configured to "Off"? Are you rooted and may have frozen something or tweaked something to prevent this?
Past software, it could be a hardware sensor on your device where the S Pen enters - I would try changing the tip of your pin (you should've gotten extra tips and a a tweezers tool for removal) and see if that makes a difference.
Device: LG Nexus 5 (D820) on AT&T's LTE
