Vivo has hinted that it will launch a premium mobile device called the X Note at some point in 2022. This event might occur sooner rather than later, as the flagship has now reportedly leaked onto a Chinese retail site. It seems to reiterate a number of the phone's more interesting specs, its larger-than-average screen included. Despite its size, it might still be in line for some of the latest panel technology.
