The Sony Xperia Z2 sports a new 5.2-inch 1920×1080 Triluminos IPS LCD with Live Color LED, which gives the Z2 the widest color gamut on a mobile device.
When viewed in person, the Z2 does indeed have a very attractive display, with good contrast and color fidelity, immediately distinguishing it from the mediocre screen of the Z1.
Just a few days I was wondering why Sony, a company so good at manipulating pixels on the big screen, is so bad at it on mobile displays. I guess Sony got its act together with the Xperia Z2.
Sony: The camera subsystem seems to be quite capable too: 20.7 megapixel 1/2.3 Exmor RS CMOS image sensor, G Lens, BIONZ image processing engine, and 4K (3840×2160/30p) video capture capability.
