Well, Kim Hyun-joon confirmed that Samsung will release a duo of top-end devices in the upcoming months, one with a big screen (which is, beyond a reasonable doubt, the Galaxy Note 4) and one made from “new materials”. This seems like a pretty serious evidence that the company is indeed working on something really interesting, and it's most probably the Galaxy Alpha. The latest rumors suggest that Samsung will unveil said device on August 4, which is even earlier than the heavily rumored mid-August announcement.
Well, according to the most recent portion of rumors and speculations, it will have little to woo us with in the hardware department – a 4.7-inch display with a resolution of 720 x 1280, 32GB on-board storage, and a fingerprint sensor. The alleged exterior, however, will be the strongest aspect of the device, as it will be the first metal Samsung device.
