From the leaked video, we can see the black colour version of the iPhone 8 which looks similar to all other previous leaks.The video is just 5sec and is of low quality which just shows the device in hand without turning on the display, probably might be the dummy unit.
At the back, we can see the similar vertically aligned Dual camera setup with LED flash in between as per previous leaks. At the front, we can find the two cameras one of them might be for IRIS scanner.The power button is on the right and volume rockers on the left of the device.
Earlier leaks we even saw iPhone 8 with rear mounted fingerprint scanner and now we have some leaks without any rear mounted fingerprint scanner. So we have to wait for few more days as APple might officially announce the iPhone 8 in Sept/Oct this year.
