Samsung announces Galaxy Alpha with metal body and 12MP camera

Samsung has announced the Galaxy Alpha - the first Galaxy smartphone with a metal frame. With its 4.7-inch 720p AMOLED screen the Galaxy Alpha is similar in dimensions to the Galaxy S5 Mini but 6.7mm thinner. The device comes with a 12MP rear camera which is unusual in that no other current high-end Samsung offers this sort of megapixel-count but no information on sensor size and technology is currently available.
