The 5.2-inch Xperia z2 has all the ingredients that a high-end device should offer; premium looks ably supported by high-end hardware and a rich, vibrant display. With the Z2, Sony has worked on the finishing of the glass body panel.  Dubbed as Sony’s most powerful flagship smartphone, Xperia Z2 is selling in US for $699.99. Also Sony’s US-based online store is offering a discount of $50.

The Display has Changed for Good:
Xperia Z2's predecessors Sony Xperia Z and Z1 offered lackluster display quality of the said devices. The primary reason for the washed out look of display was owing to TFT panels being used which have been given away for IPS panels since Xperia Z1 Compact. The change has made some impressive impact on the display of Z2. It looks a lot brighter, its outdoor readability has improved and the viewing angels have become prominent.

Best in Class Hardware:
The Xperia Z2 packs quad-core Snapdragon 801 chipset clubbed with 3 GB RAM, a first for a 5-inch device in the market. Xperia Z2 is the only high-end device in the market right now which offers 3 GB RAM making it future-proof. Normally, one doesn't expect heating issues with the high-end devices, but if we compare HTC One M8, Samsung Galaxy S5 and Sony Xperia Z2, then Z2 warms up the least. The UI experience on the Z2 with its Xperia UI is extremely smooth and quick, just like M8's Sense UI, which is not what we can say about the S5.

The sensors in the Z2's 20.7-megapixel camera has been upgraded, which vastly improve the photo quality one gets in both daylight and low-light conditions. In fact, this upgrade even allows you to shoot 4K resolution videos. The only catch here is that these videos can only be stored on 128 GB microSD cards. This feature also makes the Z2 future-proof for now; you will have to shell additional money to purchase the high-capacity microSD card to benefit from this functionality. While shooting 4K video, the device does tend to heat-up a lot which makes it a rather unpleasant experience. Images clicked in low-light conditions without flash tend to look flimsy and artificial in nature. However, the noise levels are on the lower side. The phone's 3200 mAh battery gives up to 10 hours of video playback and during the real time usage, the device manages to last well over a day.

With Xperia Z2, Sony has managed to refine its deficiencies like better display, improved camera and some future-proof features that go in unison with water and dust resistant features.
