A number of smartphones from the Samsung Galaxy Alpha series along with their specifications, features and price structures have been leaked online ahead of their official launching.

According to SamMobile, a Samsung community website, an internal document that provides details on the Samsung Galaxy Alpha devices has been obtained; these include devices such as the A3, A5 and A7.

In terms of their prices, the Galaxy A7 has been rumored to be the most expensive with which its price is likely to come between $450 and $500 without a contract. As such, it has further been speculated that Samsung will only be making the A7 available in selected regions because of its premium price.

Meanwhile, the A5 has been expected to come with a price of at least $400 and may further go beyond it while the A3 is priced from $350 to $400.

As a premium model, the A7 in the Galaxy Alpha series will be incorporated with special features such as a 5.5-inch screen with full HD (1080p) resolution, although the A7 that will be released in other countries may only feature a 720p display.

The Galaxy Alpha A5 will reportedly be comprised of a 5-inch HD display, 13-megapixel rear camera, 5-megapixel front camera, Snapdragon 400 series processor and 3200 mAh battery.

The A3 device will be including a 4.8-inch qHD screen with 960 x 540 resolution and will run on the Android 4.4.4 KitKat OS. Powered by a 1.2 GHz Snapdragon CPU, the phone is also integrated with an Adreno 306 GPU, 8-megapixel rear camera, and a 5-megapixel front camera.

All of these devices in the Galaxy Alpha series sport metallic frames that follow the design of the recently unveiled Galaxy Alpha. While the A5 and the A3 phones have already been somehow introduced in a brief video and a leaked photo shoot, details about the A7 remain uncertain.
