Apple has always had good security work for its new products, while this time, a lost-and-found mobile phone unveiled the mystery of the new generation of iPhone. It is said that the next-generation iPhone was lost by Gray Powell in Redwood City, Calif., and then was obtained by Gizmodo. They disassembled it and did a further study.

The next-generation iPhone is equipped with a front-facing video chat camera, a improved regular back-camera with larger lens, camera flash, a Micro-SIM, a secondary mic for noise cancellation, split buttons for volume and metallic power, mute and volume buttons.

Besides, some changes are also added to it: the back is entirely flat; an aluminum border going completely around the outside; it is 3g heavier and it has a 16% larger battery, and a slightly smaller screen with higher resolution; everything is more squared off.
