Apple is rumored again to be releasing a 4 inch iPhone model later this year despite having a huge success of their big screen phone (4.7 inch and 5.5 inch iPhone 6 models).
Apple will be unveiling three different iPhone models in the second half of 2015 which the iPhone 6S, iPhone 6S Plus and the 4 inch model known as the iPhone 6C according to DigiTimes.
The iPhone 6S Plus and 6C will have displays made from Japan Display, Sharp and LG Display while the iPhone 6S will have a display panel from Japan Display and LG. All these models will have NFC, Touch ID and Corning Gorilla Glass.
There are still some people missing the compact 4 inch form phones from Apple and it probably makes sense for Apple to produce a 4 inch model to cater to this market segment.
