The Xperia Z1F handset may just be for Asian markets. As for other markets, it's going to be called the Xperia Z1S instead. Same phone, different name.

According to Evleaks, who posted the snap to his Twitter feed, this looks identical to the Z1F, and is expected to be made globally available. It's going to get some impressive guts - Qualcomm Snapdragon 800 processor and Sony G Len 20.1MP camera system.

There's no official confirmation just yet to this. And no release date. Stay tuned. [EvLeaks]
