Sony Xperia Z4 32GB Black
Display
The Xperia Z4 display isn't overstretching itself in terms of display features. With a 5.2-inch LCD 'Triluminos' screen, and a pixel resolution of 1920 x 1080, the Xperia Z4 will find itself comfortably competing with most flagships, barring the QHD offerings from Samsung and LG.
Spec
The Xperia Z4 specs are directly comparable to those of the HTC One M9, which features the same octa-core 64-bit Snapdragon 810 chipset, and 3GB RAM. Provided Sony's UI works as smoothly with Snapdragon and Android Lollipop as HTC's, this means that the Xperia Z4 should deliver powerful flagship performance to match its rivals.
Camera
The new 21 MP sensor is expected to bring better performance in HDR mode, and also a higher level of detail in HD videos. Capable of recording at 30 FPS with 4K resolution (4096 x 2160), the stacked CMOS image sensor will capture videos much like it would take a normal photo.
