Sony Xperia Z2 is the next-generation model of the Xperia Z1. Introduced at the Mobile World Congress 2014, this stunningly powerful device is Sony's new flagship and boasts advanced specs as compared to its popular predecessor. In terms of design, the Z2 offers a sleek 8.2mm thin unibody aluminium construction that's about 12g lighter than Z1. It showcases a bigger 5.2-inch TRILUMINOS touchscreen with a Full HD screen resolution. The display comes with Sony's X-Reality picture engine, designed to provide superior color reproduction. 

The phablet comes with IP58 certification, just like its predecessor. This makes it dustproof as well as waterproof up to a depth of 1.5m and 30 minutes of submersion. You can take it along on the beach or to the pool without worrying about splashes of water. Powered by Google's Android OS v4.4.2 (KitKat), the device features Qualcomm MSM8974AB chipset. A 2.3GHz Quad-core processing unit is housed inside along with a massive 3GB RAM for much quicker multitasking even with heavy multimedia consumption.

Sony Xperia Z2 also improves on the image sensor of its predecessor's camera. The camera now boasts 20.7MP Exmor RS sensor capable of 4K video recording, a first for any Sony smartphone. 4K video recording means that you can capture movies at 30fps or 2160p (whereas regular Full HD recording captures at 1080p). A BackGround DeFocus function is part of the camera app and allows much clearer close up photography. Moreover, you can capture HD 720p slow-motion videos as well at 120fps. Some other notable camera features include HDR, 8x digital zoom, Image Stabilization, tracking, smile shutter, touch focus/capture, panorama mode and face detection.

The amazing handset offers Face Unlock for quick access and understands gesture input as well. Its connectivity options include Bluetooth 4.0, DLNA, MHL/USB tethering, NFC and Wi-Fi connectivity (with Wi-Fi hotspot as well). Other key specs of the Xperia Z2 are - microUSB interface, Smart Connect, GPS, 10-point multitouch, STAMINA mode for battery conservation, SyncML/ActiveSync, Facebook/Google/Twitter integration, Miracast, 3D gaming, PS certified, SensMe integration, 3D surround sound with built-in stereo speakers/xLOUD audio technology and a 3000mAh battery with up to 830h talk time/110h music playback/ 400h video playback.
