Apple is releasing a totally zero-charge iphone 4 18 in September. Analyst Ming Chihuahua Kuo predicted that the innovative iPhones will have the biggest camcorder upgrade since the iPhone 14. 
For the first time in the company history, the selfie shooter will have auto-focus. That also comes with a 6P lens and f/1.9.

Kuo said the sensor will become a program of Sony over again. It unclear whether it will definitely be different from the recent 12MP modules of the Japanese people manufacturer. 
However, without changing you will be, bringing a lot better lens and proper auto-focus seems like a main improvement.
