Sony Unveils Xperia Z2: 5.2-Inch Screen, 4K Video Recording

BARCELONA — Sony has unveiled the Xperia Z2, the company's new flagship smartphone, a mere four months after introducing Xperia Z1 and one year after launching the first phone in the series, the Xperia Z.

If it weren't for the difference in size (the Z2 is a 5.2-incher while the Z and Z1 have a 5-inch screen), one could easily confuse them to be the same phone
