Sony Xperia Z
The Sony Xperia Z is a touchscreen enabled Android smartphone designed, developed and marketed by Sony.
The phone was announced by Sony at CES 2013 and was released on 9 February 2013 in Japan and 1 March 2013 in Singapore and the UK. The Xperia Z was initially shipped with the Android 4.1.2 operating system. The smartphone has Ingress Protection Ratings of IP55 and IP57, making it dust protected, low pressure water jet protected, and waterproof, which allows for immersion under 1 metre of water for up to 30 minutes, and features a 13.1 MP Exmor RS camera sensor as well as a full HD display, encompassed in Sony's 'Omni-Balance' Design.
Alongside the Xperia Z, Sony unveiled a variant called the Sony Xperia ZL, which uses the same hardware as the Xperia Z, but sacrifices water resistance for a smaller frame, a physical camera button and an infrared blaster.
In June 2013, Sony unveiled a phablet version of the Xperia Z called the Sony Xperia Z Ultra.
Its successor, the Sony Xperia Z1, was released on 20 September 2013.
Design
The Xperia Z is a rectangular slab that marks a departure from Sony's 2012 design. The design is "Omni-Balance", which is focused on creating balance and symmetry in all directions, according to Sony. The Xperia Z has subtly rounded edges and reflective surfaces on all sides, which are held together by a skeleton frame made from glass fiber polyamide. The aluminum power button is placed on the right-hand side of the device, which is said to make one-handed operation easier.Hardware
Dimensions, design and battery
The phone's dimensions are stated to be 139 x 71 x 7.9 mm and its weight is 146 grams. It comes with a non-user-replaceable lithium-ion battery, rated at 2330 mAh.The phone is covered on the front and back by tempered glass, where the front is Dragontrail Glass from Asahi Glass Company resin-bonded to the LCD, and the back is Corning Gorilla Glass.
Camera
It includes a 13.1-megapixel rear camera with an Exmor RS IMX135 image sensor, flash, image stabiliation, HDR, face detection, Sweep Panorama, scene recognition and 16x digital zoom, and a 2.2-megapixel front camera with a Sony Exmor R sensor. Both cameras record video at 1080p.The rear camera is one of the first mobile phone cameras with HDR video.
The camera software is equipped with a quick launch feature, also known as fast capture, allowing the optional automatic capture of a photo or record video immediately after launched from the lock screen.
The burst shot mode of the Xperia Z has three speed settings of high speed, middle ans low. For unknown reasons, the resolution at the lowest speed setting is lower than the medium speed setting. At the highest speed setting, the device is able to capture 1000 photos within 68 seconds.
Tests suggest that poor image processing in the automatic camera mode leads to a quality loss that photos captured through burst mode appear at a higher quality in comparison.

Reception and sales
The Xperia Z has received mostly positive reviews from critics. Damien McFerren of CNET gave the phone 4 and a half stars out of five and said "The Sony Xperia Z combines looks, power and connectivity to supply one of the most impressive Android experiences we've seen in quite some time. The lack of Android 4.2 at launch is unfortunate and that 5-inch screen isn't going to suit everyone, but there's little room for complaint elsewhere. This is easily Sony's best phone yet, and one of the best Android phones ever released".Android Central gave the phone a positive review, saying "For Android fans, the Sony Xperia Z was one of the highlights of a fairly quiet CES. A 5-inch, 1080p phone with a bold new design language and fancy new camera technology, the Xperia Z was probably the most compelling phone of the show. And just a couple of months later, it's now available to buy in the UK. Without a doubt Sony Mobile's new baby is one of the largest, specciest Android phones around".
Audience reactions to the phone have also been positive. At CES 2013, the Xperia Z won the ‘Best Smartphone' and ‘Best of Show' awards. According to a Sony executive, Mcdougall, early Xperia Z sales have been strong. He states, "It sold over 150,000 units in its first week in Japan, taking a 24 percent market share straight away." "It may be a bit too early to say but the first signs are very positive."
