The Apple iPhone 6 was considered the most radically different model since the design of the iPhone 4. The iPhone 6 was taller, wider, thinner, and rounded at the corners. The change in dimensions was due to a desire to increase screen size while maintaining the same aspect ratio and pixel density.
