The Samsung Galaxy A7 is the latest phone to arrive and it completes the A series with a large-screen device. The Galaxy A7 features a 5.5-inch phablet-sized display, but the big highlight – as with all of the A series – is its sleek all-aluminum body. And now that the Galaxy S6 has gone official with a glass back, the Galaxy A series remains the only choice for lovers of metallic smartphones.
