According to Chinese website CNMO, ZTE intends to unveil the Nubia Z7 in March or April. The new device will be significantly larger than the 5-inch Z5S, allegedly sporting a 6.44-inch display of unknown resolution. So it is a phablet. Or maybe we should consider it a smartphone, since Sony dares to include its 6.44-inch Xperia Z Ultra in the smartphone category.
Classifications aside, CNMO reports that the Z7 could feature a new UI with a flat, minimalist design on top of Android 4.4 KitKat. An image allegedly showing the new UI’s notification center can be seen above (click to enlarge). The Chinese website assumes that the Z7 might look like the device seen in this image, but that may be just a reference design.
Rumor has it that the ZTE Nubia Z7 features a quad-core 2.3GHz Qualcomm Snapdragon 800 MSM-8974AB processor, a rear camera with flash, and 128GB (not a typo!) of internal memory. We don't know if ZTE is planning to release the new device globally. but we'll let you know when we find out.
