Today Sony Mobile officially announced the Xperia Z4 on their Japanese website. The Xperia Z4 will be the company's flagship smartphone for 2015, sitting alongside Sony's flagship tablet which is called the Xperia Z4 Tablet. Based on the specifications provided by Sony, it certainly looks like they've done everything possible to make it fit that role with regards to its hardware. Thankfully, Sony's launch page gives pretty much every specification one could be interested in, and I've organized them in the chart below.

Sony Xperia Z4
SoC MSM8994 2/1.5 GHz A57/A53 Snapdragon 810
Memory and Storage 32GB NAND + MicroSDXC, 3GB RAM
Display 5.2" 1920x1080 IPS LCD
Cellular Connectivity 2G / 3G / 4G LTE (Qualcomm UE Category 7/9 LTE)
Dimensions 146 x 72 x 6.9 mm, 144g

20.7 MP Sony Exmor, 1/2.3" Rear Facing, 25mm focal length
5.1MP Front Facing

Battery 2930 mAh
Other Connectivity 2x2 802.11 a/b/g/n/ac + BT 4.1, microUSB2.0, NFC, GPS/GNSS
SIM Size NanoSIM
Operating System Android 5.0 Lollipop

The specifications for the Z4 are certainly appealing. Potential speed and thermal issues relating to Snapdragon 810 aside, the Z4 packs what is basically the best internal hardware available for smartphone manufacturers at the moment. Snapdragon 820 won't be available until the second half of this year at the absolute earliest, and so MSM8994 paired with 3GB of RAM is the fastest you'll see in an Android smartphone that isn't the Galaxy S6.

What may be notable for some is the decision to stay with a 1920x1080 LCD. Given the issues with power consumption and brightness with current 2560x1440 LCD panels, and the relatively limited improvement to sharpness at this display size, I think that staying with a 1080p display was the right decision to make with the Z4.

The Xperia Z4 comes in White, Black, Copper, and Aqua Green

Design wise, the Xperia Z4 bears a great deal of similarity to its predecessor, the Xperia Z3. While it's not a full metal unibody design, it does have a metal frame surrounding the outside of the device. At 6.9mm it is as thin as the iPhone 6 which is impressive. Sony has also been able to include one of their 20.7MP sensors without introducing a camera hump, although the compromise is its 25mm focal length. Like most of Sony's recent products, the Xperia Z4 has an IP65 / IP68 rating for dust and water protection, which is something that now differentiates it from the flagship devices offered by other manufacturers.

At the moment, Sony hasn't provided any information about when an international release of the Xperia Z4 can be expected. It follows that the price is also unknown, although one can guess that it will be around the same price as this year's other flagship devices.

    Even the Moto X 2014 don't have the Galaxy S5 generation AMOLED. They use the S4/Note 3 gen 1080p AMOLEDs. Are you aure it's the same as S5?
  • kspirit - Monday, April 20, 2015 - link

    YES, sorry, I meant S4. But it was launched nearly over a year ago, so at the time they would have been much more expensive than they are today, kind of like how this year someone puts out a phone with an S5 screen. Clearly they can't be *that* expensive.

    Most any non-samsung AMOLED display plain SUCKS. Completely off colours, low brightness. You won't find an S6 quality panel on any other smartphone, not even S4 quality.

    *on any other smartphone from a major brand

    Samsung is basically the only company building AMOLED panels for smartphones in Bay meaningful capacity. They don't give other OEMs access to their latest tech, hence AMOLED displays on phones from other companies that don't stack up to Samsung's latest and greatest.

    in *any* meaningful capacity. Stupid autocorrect.

    Reading stuff like this makes me really sad. Because it's mostly true. I just want to have stock android with good hardware. But it's not possible.

    Low brightness? Bad quality? You must be unfamiliar with the Lumia 930.
  • nikaldro - Tuesday, April 21, 2015 - link

    400 nits, which is OK. grayscale and saturation accuracy of about 4 are NOT good. If I remember correctly, anandtech called it a "mixed bag".
    You must be unfamiliar with it too.

    I actually prefer Sony to use an LCD screen instead of an AMOLED
