The above sketch shows a new phone design patent granted to Nokia. And looking at menu/navigation bar at the bottom it seems pretty close to something of a Symbian phone design. But any given way this is very sleek and cool looking design if ever it has come to market.
As the windows phone devices don’t have hardware buttons,but rather capacitive touch buttons so it doesn’t look like a Lumia phone design. But if you look at the leaked Nokia video with upcoming Lumia phone design concepts which we have earlier reported in this article, it comes very close to one of the design demoed. Only difference is in the capacitive Lumia buttons are swapped with a hardware bar.
