Xiaomi 4 has been on the market for some time, but the official retail version, whether Unicom, Telecom or Mobile 4G, is only white for the time being. Lei Jun, CEO of Xiaomi, said on his microblog recently that the 16G black mobile version of Xiaomi 4 will be launched on October 28, while the 64G black mobile version is expected to be launched in mid November.

There is no difference in the configuration between the black version and the white version of Xiaomi 4, but the back cover of the black version is matte coated, and the frame is also sprayed with dark gray paint, which makes it more textured.
