When it comes to its smartphones, Sony has been a tough company to understand. On the one hand, they’ve made good quality handsets with solid specs, great battery life and waterproofing. But on the other, they’ve been behind on Android updates, software and key design points. Last year’s Xperia Z and Z1 tidied up some of these issues, for the most part, except that the screen quality and camera performance needed upgrades to compete with the best on the market. Enter the Xperia Z2, quite possibly the most complete smartphone Sony has produced.
