Τher concept TechConfigurations, which we are accustomed to in similar videos, shows how it could be a flexible Xiaomi Mi Mix Flex!
The device looks impressive, with me bezel-less design, 6,2 ″ screen, 95% screen-to-body ratio and a 25MP pop-up selfie camera that is needed0,8 seconds to get out of her "case". At the back there is a 3 secondary screen with Always-On feature, located "around" the vertical, triple camera module and occupies the upper half of the "back" of the device.
Of course the device has in-screen fingerprint sensor and can folded in half, completely hiding the main screen and leaving only it exposed 3", while a durable, synthetic link allows this process. Finally, the Mi Mix Flex, if released in 2019, would make sense to have 6 / 8GB RAM and Qualcomm's newest chipset, as it is called Snapdragon 855, or 8150.
