Everything you need to know about iPhone 7, which comes without Home Button?

Apple is preparing to unveil generations of iPhone 6S and iPhone 6S Plus next month with advanced quality photography and hardware upgraded to a design similar to that of models last year, according to people familiar with the matter .

The most distinctive features will be two cameras in the system, larger version of the iPhone, re-designed button on the front of the screen that responds to pressure with Haptic feedback and lack of port for audio / headphone.

However, Apple declined to comment on the possible features that will be new models of the iPhone.

IPhone while demand has fallen in the last periods of the year, partly due to fierce competition, the device continues to be the main source of revenue for Apple.

The new models will be critical for the festive year quarter, and Apple is relying on the new phones - the iPhone 7 series to support sales in 2017, when will be the 10th anniversary of the iPhone.

With the approach of cycle two-year re-designing the iPhone models this year will look similar to the series of iPhone 6 and 6S, said reliable sources within the company, but who also confirmed that the iPhone 7 will have also notable differences.

Dual cameras in larger iPhone will produce a brighter picture with more detail, according to a person who has been using a prototype version of the upcoming Apple device.

The two sensors, which capture any color and snapped the photo at the same time will produce a single picture, with more quality. Dual system sharpens pictures taken at settings lower on light.

The combination of photographs united by two sensors also allows users to magnify the picture taking more clarity. Smaller version of the iPhone 7 will not include dual lenses, said KGI Securities analyst Ming-Chi Kuo earlier this year.

Apple is planning a button on the front of the phone updated for new models - the iPhone series 7. current home buttons are physical keys that must press on the phone, but the new models will have a button that works with pressure and it is touch and makes for user feedback via a vibrating sensation rather than a real physical click. This mechanism is similar to what they touch areas or 'trackpads' that are the last line of MacBook computers.

Also, new iPhones will not have the headphone port in favor of connecting via Bluetooth and the phone port for filling. This will make room for the second headphones, said people close to the company.

New iPhone models will be supported in iOS 10, the new version of Apple's operating system coming this fall. The new software Apple will offer menu interactivity for fast access to the meetings, calendar and contacts favorite, features new messaging, a new application for controlling smart device in the home, and a new design of Apple Music .
