Vietnamese site Tinhte.vn reports that the device’s camera may also feature optimized shooting in low-light conditions.
The news seems credible as the site has in the past proved repeatedly to be a good source of information.
In addition, there is a high expectancy that Apple will bring improvements to the next iPhone camera.
The iPhone 5 has kept the 8-megapixel camera from the iPhone 4S, while reducing its size and equipping it with a more resistant sapphire lens.
The sensor from the iPhone 4 was changed upon the release of the 4S and it seems logical that the same thing happens with the iPhone 5 ad the 5S.
