The V20 Pro is the Snapdragon 765G-powered flagship for Vivo's latest smartphone series that the OEM now pitches at "various regions". The devices run on Android 10; however, they were also linked to a planned upgrade to its successor. They also all have the same 6.44-inch FHD+ AMOLED display, but differ otherwise in terms of specs.
