The next-generation iPhone could have a HD front-facing camera and thinner rear camera.

That’s according to KGI analyst Mingchi Kuo, who told investors that Apple will make “quite a few essential adjustments” to its sixth-generation iPhone, reports Apple Insider.

Kuo believes that Apple will move the front-facing camera to the middle of the iPhone, and will make it capable of capturing HD images. He also agrees with reports that the iPhone will have a 4in display.

According to Kuo’s predictions, Apple will keep the rear camera of the iPhone at 8-megapixels, but will improve the aperture range from f/2.4 to f/2.2.

He also thinks that the rear camera will be significantly thinner than the current camera found on the iPhone 4S. Kuo says that these design changes will cause “unprecedented challenges” for suppliers producing the rear camera components.

The thinner camera, along with the use of in-cell touchscreen technology, will allow for a 7.9mm thick iPhone, down from the iPhone 4S’s thickness of 9.3mm, says Kou.

This week, new reports emerged that suggest Apple will launch its next iPhone at an event in September, alongside the fourth generation iPad.
