The youtube channel everythingapplepro Publishes a video of a remarkably detailed example of the new device, as it will look in the Apple stores in September. This video actually confirms most of the rumors about the design of the device Which says that the device will have an almost completely borderless screen of 5.8 inches and will have a fingerprint sensor on the front of the device, under the screen glass.
The device is smaller than the iPhone 7 Plus, although it offers a larger screen, and is a bit larger than the usual iPhone 7.
The reporter in the video presents the device and cover for the iPhone, produced by the company that sent him the sample device (I think that apple pretty mad now).
In addition, he shows a screen shield made of glass manufactured by another company in general, which fits exactly with the simulator he received, which actually confirms the coordination between the various accessories companies regarding the final design of the device.
The iPhone 8 is scheduled to be announced at the event, which will also announce the pair of new iPhone 7s in early September.
