Vivo has confirmed that its folding mobile device tech is going clamshell for the first time, in the form of the inaugural X Flip. The presumably ultra-portable Android smartphone is now officially tipped to launch with Zeiss-tuned rear cameras, a larger-than-average cover display with useful second-screen functions and three different colorways. Its processor and TUV Rheinland-certified hinge integrity are also now official ahead of its impending launch.
