I love this phone, but cracked it (really easy to do - it's big and skinny, and cracks with just moderate flexing). Unlike other phones, the touch-screen does not work with cracks. The price to fix a cracked screen is more than the phone costs.
Ultra-huge. 6.4 inches, Full HD resolution and a Qualcomm Snapdragon 800. These are the impressive specs for the combination of a smartphone and a tablet. We are not concerned that the Xperia Ultra Z is not powerful enough to handle all upcoming tasks - but we are not so sure about about the ergonomics. Operating the device with just one hand can be a real challenge.
