Dual camera phones

The article explained how most new phones are adding an addition camera to the original single camera. This improves picture sharpness and clarity. The new P9 has engineered a way to include both these camera without the "camera bump" of most other phones. I think this is an amazing feat for phones. It's a way for photographers or people who just like to make photos, to take much better photos with greater clarity and over all quality. I can't wait to see what new ideas smartphone engineers come up with.
