Sony Xperia Z4 Unveiled In Japan

Sony Xperia Z4 Unveiled In Japan

The Sony Xperia Z4 was launched in a quiet manner in Japan today. Following the Z series design philosophy, the Z4 is Sony’s next attempt to capture the Flagship Throne of the World.

Design wise, the Xperia Z4 feels like an incremental upgrade over the previous Z series with just a few adjustments done. The Z4 is thinner than the Z3, with a 6.9mm thickness over the Z3’s 7.3mm. This has helped made the phone lighter too, with it tipping the scales at just 144 grams, 8 grams lighter than the Z3. The speaker grills have been moved flush towards the top and bottom edge, and they are longer than the Z3. For the display, the Z4 sports the same 5.2-inch 1080p display in the same dimensions as the Z3, so there is little to tell apart in the two devices. The Z4 also sports the waterproof but open micro-usb port, as found on the M4 Aqua.

As far as what’s under the hood, Sony has opted for the infamous Qualcomm Snapdragon 810 octa-core processor. This is a surprising move as a lot of manufacturers are distancing themselves from the 810, if leaks are to be believed. There is also 3GB of RAM onboard, along with 32GB of internal memory with microSD support of up to 128GB. The device is powered by a 2930 mAh battery, and comes with Sony’s custom UI on top of Android 5.0 Lollipop.


The other point of interest in the Z4 is the camera. While the rear camera is the same 20.7 MP snapper found on the Z3, the front camera has received an upgrade. It now boasts of a 5.1 MP camera with a wide angle lens and digital image stabilization. There’s also improvements on the camera on the software end.

For accessories, Sony has released color coordinated cases for all the color options.

Xperia Z4 Case

The Xperia Z4 comes in 4 color options: Black, White, Copper and Aqua Green. The device will launch in Japan this summer, but there is no official word yet on a global release.

There is little to get excited over on this device, especially if you are satisfied with the Xperia Z3. Sony is playing safe with the design, but as seen with manufacturers, design can make or break a product, even if it does not really change at all over the years.
