The "iPhone 7," which is Apple's next-generation iPhone, is already being mass-produced ahead of its September release.

There are leaked images that showcased the schematics in which it seem to confirm nearly everything to know about the upcoming iPhone design.

Also fascinating in one of the following leaked photos is a note that it showcased a precise guidance and instructions with regards to the manufacturing process of the iPhone.

The leaked photo of the "iPhone 7" indicated that the upcoming device will maintain the same general design of the "iPhone 6" and 6s. But, certain design changes of the device can be easily spotted, which includes the single antenna lines on the back of the gadget, a redesigned camera as well as the absence of the headphone jack, which is replaced by what seems to be a second speaker, according to NowhereElse.

The home button of the device has become one of tech giant's most iconic design features. And while others claimed that Apple Inc. will ditch the home button, others suggest the feature is getting a revamp.

The next-generation iPhones will utilize Macbook computers' pressure-sensitive technology for the home button, according to Bloomberg Technology.

It has been claimed that the current home buttons of the device are switches that physically press into the phone, but the latest models will have a pressure-sensitive button that provides feedback to the user through a vibrating haptic sensation rather than an actual physical click.

This mechanism of "iPhone 7" resembles to the trackpads on the latest MacBook line.

However, in commemorating the tenth anniversary of the original iPhone's release, Apple has a huge redesign plot for next year's new iPhones. In this regard, the tech company may either plan to release big visual redesigns in two consecutive years or stay with the "iPhone 6" design for one more year and then make a huge explosion with their gadgets in 2017, BGR reported.
