Apple's iPhone 6-Plus is a very thin smartphone with a depth of only 0.28 inches (7.1 mm) weighing in at 6.07 ounces. Samsung recently introduced a thinner smartphone for the Chinese market called the Galaxy A8 with a depth of 0.23 inches (5.9mm) that weighs in at 5.3 ounces. Better yet, that's based on a smartphone having a larger 5.7 inch display. Samsung plans to drive the thinness of their smartphones down over the next two years so that they could introduce a foldable dual display smartphone that's no thicker than what the iPhone 6-Plus is today. Our Patently Mobile blog has published a report this morning illustrating Samsung's latest round of multiple display smartphone concepts and features. Samsung has been working on this for years and we've covered all of their major patent filings on this invention category (one, two, three, four and five). With Samsung losing out to Apple as the top premium smartphone on the market today, Samsung needs to introduce a new dimension to smartphones in the future as they once did with their phablet. Will they be able to pull it off again? Only time will tell.
