So this is it. After a series of leaks and rumours, the Sony Xperia Z4 has been officially announced today in Japan, but we are sure that it will be launched throughout the world in the coming weeks. So, how different is the Xperia Z4 from its predecessor, the Sony Xperia Z3? Well, nothing has changed except the processor and the front-facing camera. The device is now just 6.9 mm thin, and weights 144 grams, with improvements to the metal used in the frame of the device.
The Sony Xperia Z4 features a 5.2-inch FHD IPS LCD display, 2.0GHz Snapdragon 810 processor, Adreno 430 GPU, 3GB RAM, and 32GB internal memory with an option to expand it using a microSD card slot. There’s 20.7-megapixel primary camera with a 1/2.3-inch sensor, similar to what was found in the Xperia Z1, Xperia Z2, and Xperia Z3, with autofocus, single-LED flash, and 4K video recording.
The front-facing camera has been upgraded, and now it comes with a 5-megapixel Exmor R sensor with 25mm wide-angle lens.
