There is no official info about the hardware of the phone, but of course, there are some speculations. The ZTE Nubia 5S is expected to take advantage of the Qualcomm Snapdragon 800 SoC, clocked at 2.2GHz. The Nubia 5S is also expected to come out with 2 GB of RAM, 5-inch 1080p display, 13 MP rear and 5 MP front cameras, which is pretty close to the current standard for high-end smartphones. It is currently unknown if the device will get the same Konica-Minolta lens from the Nubia 5. It might get a dedicated camera button and IR blaster, though. Although the speculated ZTE Nubia 5S specifications sound excellent on paper, the device will face some very rough competition from its local peeps Xiaomi, Oppo, Meizu etc.
It is currently unknown if the device will be available outside of China.
