There should be an app to locate your S Pens if they're nearby.

If FitBit can do a locator app and an S Pen can tell you the exact second it disconnected so it is smart enough to know when and where it is if it bounces off of a phone's location. This should be an app that comes automatically installed with S Phones, either upon purxhase or next available update. Pleeeeeeeeease, Samsung. You're so awesome, be that much MORE awesome!!!!!!! #GetSamsung #DumpApple

There would need to be hardware in the Spen for that to happen.

Or, maybe you need to be more careful with it.
