The screenshots you see below are believed to be of the Xperia Z3 Compact. However, if this is indeed the case, the handset is different to the previous supposed Xperia Z3 Compact leak that had the front-facing camera towards the edge of the handset. This leak shows a front-facing camera in a different position, so we could be looking at two different handsets here.
Anyway, according to the source, this model is reported to have a 4.6-inch 1080p display, Qualcomm Snapdragon 801 chipset, 3GB RAM, 20.7MP Exmor RS rear camera and stereo speakers. Take a pinch of salt with these specs as always.
