Photos of an iPhone 5S prototype posted on MacRumors appear to confirm both a next-generation chip and multiple changes to the device’s camera flash and microphone system. While A7 branding is notably absent from the prototype, smaller numeric markings on the chip are consistent with true generational changes, seemingly indicating that this is not just an upgraded A6.

Additionally, the flash is now very clearly shown as twin LED — the LEDs could possibly be different colors, perhaps for improved skintone color accuracy in low-light situations. Also, the microphone hole is now circular rather than pill-shaped, and the camera looks a little different, as well. However, this is an early prototype, so the design of the device may have already changed. Other alleged iPhone 5S photos were leaked last week.
