The Galaxy A7 Series is composed of the A7 with the phone's cover integrated into a narrative around water and its characteristics. Water particles tend to attract each other to keep surface area to a minimum. Inspired by this, all surfaces of the A7 were given a surface tension to create natural round sections. For the CMF design of the back-glass, Samsung set out to capture the perfection and most precious aspect of water. The cover of the A7 adds a new perception. It expresses the image seen from underneath when light hits the surface of water and diffracts, not simply the image from above when looking at the dispersion of water waves.
