Samsung Galaxy Note 3 Prototype model posed in front of camera for some clicks. The images were found on both TechTastic and Sammobile Site. According to their report, prototypes of the Galaxy Note 3 have been shipped in "very low quantities" for the purposes of Research and Development (R&D Purposes).
As we all can only see the front of the device, it is difficult to say that the upcoming Note 3 will feature S Pen or not. But, as it is a prototype device, Samsung might add the S Pen feature on the final model.
Samsung Galaxy Note 3 is expected to come with 5.99-inch Full HD Super AMOLED display, 2.3GHz Quad-Core Qualcomm Snapdragon 800 Processor or a Octa-Core Exynos 5 Processor, 13MP camera and Android 4.3 Jelly Bean with Samsung's own newest TouchWiz Nature UX 2.0.
