In patent figure 9 noted above we're able to see the rounded edges of the phone and a slightly recessed top side and on the figure 10 that part is pop up out and we don`t know for what that feature is. Looks like an extension of the phone that slides out for a mystery purpose.
The rounded edges on figure 9 shows some of the applications that might work on them.
These pictures were revealed by the U.S Patent and Trademark office past week.
