sony-xperia-z4Last week Sony unveiled their latest smartphone in their home country of Japan. It was done without the usual excess of hype and endless rumours and speculation and it took a few by surprise. There are rumours that when the Z4 launches internationally, it will be known as the Z3+ however these are unconfirmed as yet so at the moment we will still refer to it as the Xperia Z4 for the moment. So what can we expect from Sony's newest handset?

With a similar design to its predecessor the Z3, the Xperia Z4 features a very shiny metallic frame and is dust and water resistant. Sporting a 5.2-inch 1080 x 1920 resolution display, the new Xperia Z4 is slimmer at 6.9mm and lighter at 144 grams than the Xperia Z4.

On the rear of Sony's new flagship smartphone is a camera which is also very similar to the one which featured on the Z3, a 20.7-megapixel camera featuring a Exmor RS sensor, an LED flash and of course autofocus. The camera on the front of the Z4 has been upgraded to a 5.1-megapixel, wide-angled camera complete with digital image stabilisation. The trend for improved front-facing cameras for mastering those flattering selfies certainly shows no sign of abating.

There has also been a make-over on the inside of the Xperia Z4 as it comes with the powerful Snapdragon octa-core 810 processor which boasts 64-bit technology. The 3GB of RAM is on a par with the Z3 however the Xperia Z4 has 32GB of built-in storage which is expandable up to 128GB with the microSD slot. The 2930mAh battery is a little bit smaller than the 3100mAh found in the Z3 however with a faster and more efficient processor, it's unlikely to have any impact on the battery life.

Initially the Sony Xperia Z4 will be available in Japan in a range of four colours which include Black, White, Copper and Aqua Green. It's thought that the Z4/Z3+ will be rolled out to other countries soon so keep an eye on our blog for more information as we have it.
