Audio and Connectivity
The Vivo V21 provides satisfactory audio experience through its loudspeaker, although it lacks a 3.5mm headphone jack, which might disappoint audiophiles. Connectivity options include dual-band Wi-Fi, Bluetooth 5.1, and USB Type-C with OTG support. While it supports GPS, GLONASS, GALILEO, and BDS for precise location services, the absence of NFC and radio might be limiting for some users.
