Audio and Connectivity
The OPPO A78 doesn't skimp on audio capabilities, incorporating stereo speakers that enhance the overall media consumption experience. For those who prefer wired audio, the inclusion of a 3.5mm headphone jack is a highly appreciated feature. In terms of connectivity, the phone supports Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 5.0, and GPS systems, which include GALILEO and GLONASS. NFC is included but may depend on market availability.
