KGI analyst Ming-Chi Kuo has revealed details about the iPhone 7 as well as the Cupertino tech company’s plans for unveiling a 4-inch device.

According to report on 9to5Mac, in an investor’s note, Kuo shared that a 4-inch iPhone is in the works, which “resembles an upgraded iPhone 5s.” This 4-inch device is expected to hide an A9 processor under its hood and come with a metal casing unlike the iPhone 5c.

The 5c device was Apple’s last 4-inch smartphone and was discontinued after the latest 6s and 6s plus were announced, as noted by International Business Times.

The 4-inch smartphone may not feature 3D Touch technology and Apple may launch the device in the first half next year, as shared by Kuo. He is also of the opinion that there is a good market for 4-inch iPhones, according to 9to5Mac.

Kuo also revealed details about the iPhone 7 and said that Apple will continue to keep up with tradition and announce its 2016 flagship in the third quarter.

The upcoming models are expected to maintain the 4.7-inch as well as the 5.5-inch display sizes. He predicts that these models, iPhone 7 and iPhone 7 Plus will house an A10 chip each. The former may have 2GB RAM, while the latter would receive 3GB of memory.

Rumors about the iPhone 7 being waterproof and dustproof have been swirling and guesses are being made at whether it will sport the 7000 series aluminum casing.

However, in the note, no details are provided about the device being waterproof and dustproof or whether the company is considering a new material for the iPhone’s form factor.

Kuo anticipates that Apple would be seen shipping 20 million and 30 million units of the 4-inch iPhone, by the end of next year.

Apple fans can keep coming back for more rumors, speculations and updates on the iPhone 7.
