Xperia SP leaked back pictureXperia SP leaked front picture

We've already heard plenty about Sony's upcoming mid-ranger, the Xperia SP (codenamed "HuaShan") -- said to be a dual-core mid-ranger packing a 720p screen. And although there's no Sony press conference at this year's Mobile World Congress, we're expecting to see it next week in Barcelona.

Today new reports hint at some interesting build quality details for the SP, including an apparent aluminum-framed chassis (with plastic back) and customizable clear element, similar to the Xperia U. These latest details come from XperiaBlog, which cites a "trusted source" with knowledge of the device, and if accurate it's interesting to see Sony revisiting the transparent element as a design feature.

The screen size is also reported at 4.6-inches, which would put it on par with Sony's late 2012 flagship, the Xperia T. And the rear camera is reportedly a 8MP Exmor RS unit -- a lower megapixel count than the Xperia T, but with a more advanced sensor. Storage is said to clock in at 8GB internal, expandable via microSD. Other stats include measurements of 130.6 x 67.1 x 9.98mm and a fairly hefty weight of 155 grams.

MWC is traditionally where Sony shows off its mid-range devices, so we'll hopefully learn more about the Xperia SP in Barcelona in the days ahead.
