Here we go again, folks. Samsung is reportedly gearing up to release its first metal flagship next month under the Galaxy Alpha moniker.

That’s according to Korean-language reports based on “industry sources” picked up by the usually reliable Korea Herald.

Samsung is reportedly trying to preempt the release of larger iPhone models this September with a premium metal-built device of its own. The device may be called Galaxy Alpha, claim the Korean sources, though you may know it better as the Galaxy F, a name that appeared in several leaks and reports so far.

For the record, Samsung trademarked the “Galaxy Alpha” name at the beginning of last month, suggesting that may be the commercial name of the device.

The Galaxy Alpha will reportedly feature a 4.7-inch Super AMOLED display, a “premium metal” body, and an Exynos 5 Octa processor. The device is said to be just 6 millimeters thick, which would be substantially thinner than the Galaxy S5 (8.1 millimeters) and the iPhone 5s (7.6 millimeters).

Samsung refused to comment on the rumors, but a source claims the company calls the Galaxy Alpha “card-phone” internally, for its slim profile. The device could launch next month according to ETNews.

It appears that Galaxy Alpha will be the first in a new lineup, independent of the Galaxy S line. The smaller screen may be a transparent way for Samsung to counter the new iPhone, which is rumored to come in two sizes, 4.7-inch and 5.5-inch. That would make the Galaxy Note 4 the second hit in Samsung’s one-two punch against Apple.

It remains to be seen if this report is accurate. In particular, the ultra-slim profile of this fabled Galaxy Alpha raises eyebrows. In addition, previous rumors put the screen size of the Galaxy F at 5.25-inch, and this is the first time we’ve heard about a smaller screen. However, if Samsung’s motivation here is to counter the iPhone before it’s even released, it would make more sense to go for a smaller size.
