Flip you for it! Tails or rear-facing camera?
Comparing the cameras on the iPhone 5c (left) and 5s (right), we see little difference between the two. The one difference between the 8 MP rear-facing cameras is the aperture. The 5c boasts an aperture of f/2.4 compared to the f/2.2 of the 5s.
Additionally, the vibrator motor assembly in the 5c is actually slightly larger than that of the 5s, despite its similar component design.
