Reviews Word on the street

Xperia Z3 Compact  vs Galaxy Alpha 

It fits in any pocket, is easy to use one-handed, has a lovely screen, a top notch camera and it's fast.
Xperia Z3 Compact

Despite getting a larger, 4.6” screen, the Z3 Compact remains just as petite and single-hand-use-friendly as the original, and it’s got an even faster processor and longer-lasting battery.
