The Xperia Z3, which lands alongside a new tablet and mini phone to complete the family (the Xperia Z3 Tablet Compact and the Xperia Z3 Compact), is a really good phone that does it all, on paper at least.
Sony told me that the reason these flagships are coming thick and fast is simply because it wants to start making waves in the high-end smartphone market, and the way to do that is always offer the best innovation.
