Audio and Connectivity
The Vivo Y21s includes a loudspeaker and retains a 3.5mm headphone jack, ensuring compatibility with a wide range of audio accessories. Connectivity options are robust, with Wi-Fi 802.11 a/b/g/n/ac providing dual-band support, Bluetooth 5.0 for reliable device pairing, and comprehensive positioning systems including GPS, GLONASS, GALILEO, and BDS. Notably, NFC functionality is included but varies by market and region—a point to verify if this feature is crucial for your usage. FM radio and a USB Type-C 2.0 port with OTG further enrich its connectivity suite.
