Sony currently supplies the camera sensor for the iPhone 5S rear iSight camera, and according to a recent report, Sony will supply sensors for both cameras on the iPhone 6.
The iPhone 5S has an 8 megapixel rear camera, and a front facing 1 megapixel camera, and if Sony does supply both cameras, this would suggest that Apple will improve the front facing FaceTime camera.
Which could mean that the iPhone 6 will get a full HD capable front facing camera, which would be an improvement for their FaceTime app.
As yet we do not know exactly what camera sensor will be used in the back of the iPhone 6, there have been reports that Apple will continue with an 8 megapixel camera, although it will be an improved version.
The front facing camera on the iPhone 5S is OK, not exactly the best quality, especially in low light, when compared to the rear camera on the handset, lets hope that this rumor is correct, and that we will see a much improved FaceTime camera on the iPhone 6.
The iPhone 6 is rumored to come with a larger display than the 5S, possibly a 5 inch display, and it may feature sapphire glass and possibly solar charging built into the display.
