At the end of October, the Nubia X smartphone was featured with 2 screens. One of these displays will be colored and the other on the reverse is made using electronic ink technology like what we could see on YotaPhone. Its main accent will be two monitors, the theory is similar to the Russian phone YotaPhone and the last Nubia X from the Chinese ZTE. The back panel also has a color OLED screen.
The new inside information shows that the Chinese company Vivo will also release a 2-screen device. The main display, 6.26 inches, occupies 93.6 percent of the front panel, and a 5.1-inch display on the back of the case.
The main screen is used with OLED technology and will get a diagonal of 6.4 inches with Full HD + resolution. The diagonal of the second OLED screen is unknown.
It is assumed that NEX 2 may be given in vivo next month.
