Sony's much awaited Smartphone is in news these days. Sony has done pretty good job in the phone.
If you dont already know about the phone let me give you some information about it.
A 4K camcorder and a 20.7 MP camera, combined in a smartphone
The Xperia Z2 combines 4K video capture with a large 1/2.3(1.10cm) 20.7 MP Exmor RS™ for mobile image sensor, Sony’s award-winning G Lens and the intelligent BIONZ™ for mobile image-processing engine. This unique combination means the Xperia Z2 has the same quality and performance as a real compact digital camera. The result is images that are delivered with a superior sharpness, clarity and brightness – always.
Motion detection for blur-free images
Are you living life in the fast lane? Just keep moving – with the best camera phone at hand, your pictures will always come out sharp. The bright F2.0 lens and high sensitivity sensor enable you to take photos with a higher shutter speed. The BIONZ™ for mobile image-processing engine has Motion Detection – it chooses a higher shutter speed to capture blur-free images when your subject is moving. The Superior Auto mode does all the hard work for you.
Slow down the moment with Timeshift video
Clear and loud. With Sony’s audio technologies, you can be sure to experience the best sound, always.
Digital noise cancellation
Block out the world around you with digital noise cancellation that reduces up to 98% of all ambient sounds. Based on a technology referred to as Active noise control, this technique removes the lower-frequency portions of the noise, preventing high-frequency noise from ever reaching the ear. Since noise-cancelling technology is built into the smartphone device, you can enjoy noise-free sound with the sleek MDR-NC31EM headphones. These headphones sample surrounding noise through a microphone. When compensated by the DNC circuit in the Xperia device, the resulting output is a clear, noise-free sound.
