Audio and Connectivity

For audio needs, the device retains a 3.5mm headphone jack, which is gradually becoming scarce in modern smartphones, and offers a loudspeaker for media playback. Connectivity features are comprehensive, supporting Wi-Fi 802.11 a/b/g/n/ac with dual-band capabilities, Bluetooth 5.3 for efficient energy use and extended range, and support for key navigation systems such as GPS, GLONASS, GALILEO, BDS, and QZSS. However, the phone lacks NFC capabilities and a radio but compensates with USB Type-C 2.0 and OTG support for external devices.
