Jeff Bezos has another card up his sleeve. Amazon is working with their component suppliers in Asia to test a smartphone according to sources with The Wall Street Journal. What this means is that Amazon is going to penetrate the smartphone market with their own products just like they did with the tablet market with the Kindle. Likely the smartphone will be based on Android just like the Kindle Fire. The screen size of Amazon’s tablet is expected to be 4-5 inches. According to the Wall Street Journal’s sources, the device will start mass production later this year or early next year.
