Ivo Maric took the design on the patent applications and whipped up a Samsung Galaxy S5 concept based on the patent that was awarded to Samsung on New Year's Eve. Just like the sketches, Maric's phone includes a curved display on each side of the device. Jermain Smit took a different tact. He used the drawings from the design patent to come up with a Samsung Galaxy Note 4, which also features the curved display.
Concept models are just that, a concept designed by a third party based on information gleaned from leaked images and specs or based on nothing more than the designer's own imagination. You can check out what Maric and Smit came up with by clicking on the slideshow below.
