A 4.4-inch Sony D2403 revealed, set to compete with the Moto G?

Before getting into the rest of the similarities, the still mysterious D2403 differs in one very obvious way: it's got a 4.4-inch 540 x 960 pixel (qHD) display, in contrast to the 5-inch M2. That said, the D2403 appears to be powered a very similar hardware configuration, including a 1.2GHz quad-core Qualcomm Snapdragon chip with an Adreno 305 GPU (likely the Snapdragon 400 MSM8926), 1GB of RAM, and an 8-megapixel rear shooter (0.3MP at the front). The only other clue we have is that the device that was tested seemingly sported 16GB of on-board storage, which is rather healthy in this class.

On the software side, the Xperia phone in question ran on the latest Android 4.4.2 KitKat, which, if the D2403 ever becomes an actual device, is likely to make an appearance with Sony's skin on top.

Of course, such a configuration would make the Sony Xperia D2403 a worthy competitor to the seemingly unbeatable Motorola Moto G, though that may not be what Sony is going after -- especially if it adopts Xperia M2-like pricing. With that in mind, it wouldn't be overly surprising to see the D2403 materialize into an M2 mini of sorts. Time will tell.
