The Sony Xperia Z is Sony's flagship mobile device for 2013. The model is adorned with a 5-inch display with a resolution of 1920x1080 pixels. The phone also has a 13 megapixel camera, a quad core processor at 1.5 GHz from Qualcomm, and 2 GBs of RAM. The Xperia Z comes with Android 4.1 (Jelly Bean). The internal memory size is 16 GB, but the possibility exists to add an SD card. Like many of Sony's mobile phones, the Z is dust resistant and waterproof to one meter. With a sturdy device like this, dropping the device in the toilet does not need to cost you anything, other than your dignity.
