From what we understand, this special edition of the Xperia Z3 will also come with several custom Disney themes, including one for the box office hit animation Frozen. Apart from that, the Purple Diamond Edition Z3 is actually identical to the standard model – we're just looking at a new color, and one that is pretty much synonymous with the flagship Xperia line. With the Z3, Sony decided to axe purple from the list of options, but it would appear that it's still fond of the color.
In case you're unacquainted with the Sony Xperia Z3, it's a 5.2-inch dust- and water-resistant smartphone with a Qualcomm Snapdragon 801 processor, 3GB of RAM, a 20.7-megapixel Exmor RS sensor, and Android 4.4 KitKat with Sony's proprietary Xperia theme perched on top. At 0.29 inches (7.3 mm), the Xperia Z3 is among the thinnest flagships currently available on the market and we reviewed it favorably back in 2014.
