Samsung opens up S Pen SDK to devs
Strong sales of the Samsung Galaxy S II have fueled Samsung’s phone division success and as the demand persists the Korean company has revised its 2011 sales forecast upwards. Apart from the Galaxy S II, the company is also basing its more optimistic estimate on expectations for sales of 2 million units of the Samsung Galaxy Note, the 5.3-inch powerhouse which sits between a phone and a tablet.

Now, it’s definitely not a device for the mass user, but creatives (and we don’t mean baristas) can make great use of the added space. And now, Samsung has released the SDK for its S Pen stylus for the Galaxy Note. This opens the door for Android developers to add support for the S Pen in their applications. The SDK weighs 2.43MB and comes with four major features:

- CanvasView : basic background for drawing,
- Pen Setting Popup : a pop-up panel for adjusting the width, opacity and line color,
- Eraser Setting Popup : Panel for adjusting width for eraser,
- Undo/Redo : Enable undo/redo previous draw.

You see people? Samsung developed the S-Pen applications and software themselves and even though they are marketing it as a unique feature of one device - they are releasing the SDK freely to developers. That's what Samsung does Apple bought the Siri technology and software from an independent company (by buying that company), closed down the original application which was available to all of the devices, and marketed it as a unique feature of one device - and one device only - while also not giving anything to the developers or anyone else. That's what Apple does. See the difference?
