Image 4 (comparison with iPhone 5):
From the background, it seems that the pictures were taken at the assembly line of an operation stage. The photographer has showed the front and rear side of the housing, which looks very similar to the iPhone 5. However, the reason why we say it is a suspected iPhone 5s rear housing is that the specific information below the logo, which are replaced by “X”. Usually, the parts with “X” stand for test prototype.
Inside the rear housing, we can find some changes when comparing it with iPhone 5. First, the “iPhone 5s” has two less screw holes on the left side which are used to fasten the LCD. Second, the position of 3 screw holes used to fasten the logic board has been removed (not sure whether caused by the change of logic board).
