TENAA has certified a new phone from the Vivo sub-brand iQOO. Its specifications are nearly identical to that of the Neo, a 2019 gaming phone. However, it has what appears to be a Snapdragon (SD) 855 processor rather than the older device's SD 845. Therefore, it seems the 2 phones are an original and refresh respectively.
