For starters, the ZUK Z2 Pro comes with a smaller 5.2-inch display, as opposed to the 5.5-inch Z1. It also makes a switch from IPS LCD to AMOLED, but resolution remains FullHD.
On the inside we find the latest Snapdragon 820 chipset - while ZUK settled with the aging S801 for the Z1, the Z2 Pro gets the proper flagship treatment. And in line with this concept, you'll find 6GB of RAM and 128GB of storage on board, from day one. Later on, a downgraded version will be made available with still plentiful 4 gigs of RAM and 64GB internal storage.
As for imaging, we're looking at a 13MP ISOCELL rear camera with 1.34μm pixels, F/1.8 aperture and phase detection autofocus. 4K video recording, is supported, of course. Selfies aren't just an afterthought either - an 8MP front-facer with 1.4μm pixels and a reasonably bright f/2.0 lens sounds promising on paper.
The list goes on though. The Z2 Pro has a fingerprint sensor in the home button, but then so did the Z1. This one, however, offers better resolution and will also improve the more you use it. The Z2 Pro is big on all kinds of sensors too, and packs in a heart rate sensor, UV sensor and an altimeter, for all you outdoor types.
All-round excellent connectivity is to be expected, and the Z2 Pro does indeed deliver. ZUK says the smartphone supports 23 cellular network types, and comes with 4G LTE and VoLTE support too. Wi-Fi ac, Bluetooth 4.1 and a GPS receiver are also part of the package. Wired connectivity takes place over USB Type-C, proper USB 3.1 too.
The smartphone measures 145.4 x 70.5 x 7.5mm and weighs in at 145g. That's enough room to fit in a 3,100mAh battery, which you can top up fast thanks to Quick Charge 3.0. The ZUK Z2 Pro ships with Android Marshmallow too.
The top-specced 6GB/128GB version of the Z2 Pro is available in China starting tomorrow for CNY 2,699, or just under $420. The 4GB/64 variant will make it to stores on May 10, and while price will logically be lower, the precise number hasn't been announced.
