The Xperia Z3 Compact on the other hand could be rather more enticing. The Z1 Compact is still one of the best small-screen phones around and the Z3 Compact should be a substantial upgrade, with rumours suggesting a 4.6 inch 1080p display, a 2.5GHz quad-core Snapdragon 801 processor, 3GB of RAM and a 20.7 megapixel camera.
