Well-known French site Nowhereelse.fr published some photos of the metal frame of the Galaxy S5.
The leaked photo could provide some confirmation on the materials that the next model might adopt.
Thus, Samsung may abandon polycarbonate for its flagship devices in favor of aluminum.
In addition, given the slightly larger dimensions of the frame than those seen in the Galaxy S4, the image may indicate the implementation of a larger display.
While it cannot be said for sure whether this is indeed a part of the next Samsung phone, the source of the info, Nowhereelse.fr, has proved quite reliable in the past.
