The Sony did a safe bet with their Xperia Z2: maintained differentiated characteristics of Z1, upgraded hardware and let the lighter design. The top of the line cell can still bothering those who are not used to an appliance glass, but is an elegant and robust smartphone. Check out our review of the Xperia Z2 below.
Design
The Xperia Z2 keeps the features of its predecessor, the Xperia Z1: it is square, with tempered glass on the back and front, without the presence of physical buttons and a large screen. The similarities, however, end there. The Z2 is wider, with 73.3 mm, but thinner, with its amazing 8.2 mm.
The result is a very good grip, whereas the cell has more gray and rounded edges. But not everything is perfect: the rear glass is slippery and unfortunately gets tagged digital after continuous use. The weight 7 g lighter than the Z1, Xperia makes a difference in Z2. The 163 g are well distributed and you have the impression of carrying a smartphone lighter than it really is.
Excess glasses bring two problems plus marks in your digital appliance: it scratches more easily and also heats up quickly. The heating can become a problem which is repeating of the same of history Z1.
Screen
The Z2 has 5.2 inches of display with a respectable resolution of 1920 x 1080 pixels, resulting in a density of 441 ppi. The screen is a LED Triluminos, with the same technology of Sony TVs, and it's really impressive. The user printing the displayed image is more "enlightened" than similar devices, with vivid colors and great contrast. The screen also responds well to commands, even when the user makes use of multitouch.
The three buttons at the bottom - back, home and screens - are integrated into the rest of the display. Thus, one of the problems is the use bump into one of these commands while you use the application.
Performance
The Android 4.4.2 smartphone in KitKat is native and works fluidly with the peculiarities of the adaptation of Sony. At the time of its international launch at MWC 2014 in Barcelona, the system came with a desktop background in honor of the World Cup in Brazil. In the national version of the phone, it came with a standard background of the Japanese manufacturer.
The differences of the system outside its speed, are minimal. This version of Android, for example, is the one that allows connection with SmartBand Sony bracelet. It makes it possible to account information such as the number of steps you take in a day and receive notifications from social networks directly on the wrist. The phone includes such data transmission.
The processor of the Xperia Z2 is a new model of Qualcomm, Snapdragon called 801. Circuit is a quad-core 2.3 GHz frequency. This speed allows fast startup, and take pictures in a few seconds without crashing. The Adreno 330 graphics processor makes for a compelling performance for images. The RAM is 3 GB, accompanied by an internal standard 16 GB space. Unfortunately, this internal memory there is only 11.57 GB votes to be occupied by applications and programs.
The expansion via microSD is quite satisfactory: the Xperia Z2 can get to have 128 GB of space, enough to have a large collection of apps. Moreover, the model has Wi-Fi, DLNA, GPS / GLONASS, NFC, Bluetooth 4.0, MHL 3.0, USB OTG and USB 2.0 Micro-B port with USB and charger.
Apart from all the features, the Z2 is waterproof, a large gap with rivals within or outside the Android ecosystem. To use it in the water, like the Z1, you need to close the side entrances. With everything closed, it supports 30 minutes submerged in up to 1.5 m deep.
The hype of Xperia Z2 theme was the Michael Jackson’s "Slave to the Rhythm.". The song, along with seven others, was released with Xscape album, which is being offered along with the new phone from Sony.
This investment led to a change in the hardware of Z2. Sony implemented a function called Clearaudio + to enhance the stereo sound of the instrument. The sound output of the smartphone is quite good, and is located at the bottom of the smartphone.
The headset has a baffle 98% of the room volume. In our tests, in fact, not very noticeable external noises above 60% of the volume of the cell. That is, if you love listening to your favorite compositions with your headphones, this may be the right smartphone for you.
With 3,200 mAh battery, the Xperia Z2 lasted a day and six hours, mainly using social networks. It is greater than the average income market. Viewing videos constantly, lasted between five and six hours on battery. Most disturbing, however, was warming it inside the smartphone.
The benefit of the Xperia line from Sony is that despite the battery is well protected inside the cell, it maintains that benefit for about a year. It is a gadget that is worth investing the quality of its components.
Camera
It's nice to shoot with the Z2. Its great advantage is that it makes videos in 2160p, 4K quality, 30 frames per second. This results in filming with a greater degree of realism and detail. Moreover, the photos are made with 20.7 megapixel sensor on the rear camera. Have the front photography, selfies, is performed with a capacity of 2.2 megapixels.
The result of the photographs clicked outdoors under natural light, is quite satisfactory. The camera captures details such as the flaws of painting in the image below. Nevertheless, the application of Sony camera has a high delay to set the focus, which can cause the user to lose a few clicks. Clicks in low light environments, such as the second picture of the sequence, tend to become granulates. The result, however, is higher than most smartphones in the market.
In automatic mode, the color balance is far from ideal indoors. In low-light photos, images tend to get "yellow", but nothing that a setting in the application itself can not solve.
The flash keeps it simple, with LED technology, but enough to help in very dark or night scenery. The increase of image capture sensors, compared to the Z1, resulting in more crisp and sharp photos.
Values
The Xperia Z2 is a sophisticated model and suitable for those who have large hands. Comfortable and more rounded, seems like a natural evolution of the Z1. There is a revolution within the line of Xperia phones from Sony, but it certainly continues the good work of the manufacturer.
