Connectivity
While the Oppo A3x lacks NFC and radio functionalities, it makes up for these omissions with robust connectivity options, including Wi-Fi 802.11 a/b/g/n/ac (dual-band), Bluetooth 5.3 with advanced codecs like aptX HD, and comprehensive satellite navigation systems like GPS, GALILEO, GLONASS, BDS, and QZSS. The USB Type-C 2.0 port with OTG support enhances connectivity, allowing for easy data transfer and peripheral connections.
