Not Support Samsung S-Pen Plugins?

[Grauw]

Our solution which is simple and looks like it works well so far:

1.         UICamera: Support mouse (pen) on devices.
2.  
3.         We tweak NGUI so that in stead of disabling mouse on device,
4.         it gets a way to disambiguate native from touch-emulated mouse events.

For fix it new NGUI. In UICamera you need to change line:

1. if (currentScheme == ControlScheme.Touch) return;

On this, and s-pen start working as expected:

1. if (currentScheme == ControlScheme.Touch && Input.touchCount > 0) return;

You can test it with OTG cable and mouse connected to your tablet/phone.

If anything, it should be:

1. if (currentScheme == ControlScheme.Touch && activeTouches.Count > 0) return;
