To provide information on what I think is happening, when a touch event occurs (either through a finger, pen/stylus or mouse), a MotionEvent is generated in the Android framework. With this event, I can check what the tool type is. If the tool type is reported as an eraser (MotionEvent.TOOL_TYPE_ERASER), then I respond by switching to the eraser tool until I get an event that indicates that the touch was released. So your S-Pen is being reported as an eraser. I don't know how that's possible, but based on your description, that's the only thing that makes sense. Let me ask this - if you use the Samsung drawing app on the device, does it seem to correctly respond to the stylus? Or does it also act like it's an eraser?

Thanks,
Mike
