Apple produces a line of smart phones working with Apple’s iOS mobile operating system. From 2007 to year 2016, iPhone has facilitated its customers with many advanced features and supplications and it is just a beginning towards a greatest future.

There exists a total of nine generations till March, 2016. First five generations have a scratch resistance glass screen, a 3.5 inches liquid crystal display. While for iPhone 5 it turned into 4 inches thickness, allowing multiple fingers sensing. As it comes to the resolution, first three generations have a resolution of 320×480 at 163 ppi, which reached to 640×1136 at 326 ppi for iPhone 5. Touch screen is basically designed to be touched through bare fingers because gloves create a blockage for current. A stylus will be good choice at that moment. iPhone provides minimum hardware interactivity by featuring five buttons including physical menu button, sleep button, two volume adjustment buttons and a ring/silent switching button. An interesting feature which is reported in iPhone 6S and 6S plus is “force touch” provides information about the intensity of touch. Latest iPhone devices feature six sensors, which are used to adjust the screen based on operating conditions, enable motion-controlled games, and location-based services.

Up to the iPhone 4, all iPhone models, as well as other iOS devices were manufactured exclusively by Foxconn, based in Taiwan. In 2011 Apple changed its outsourcing strategy by increasing its supply partners. The iPhone 4s in 2012 was the first model which was manufactured simultaneously by two stand-alone companies; Foxconn as well as Pegatron, also based in Taiwan. Although, Foxconn still holds a major production share but an increasing trend has been observed in Pegatron's orders. Pegatron has produced a part of iPhone 5C in 2013 and 30% of iPhone 6 devices in year 2014. The credit for production of iPhone 6 goes to Foxconn, completely and solely. Apple is a followed like a trend in recent times. It’s a trend setter among other mobile companies because of the brilliant brains behind each fully finished and detailed product.
