Audio and Connectivity

For audio, the phone includes a single loudspeaker and a 3.5mm headphone jack, catering to traditional wired audio users. Connectivity options are robust, with support for Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 5.1 with aptX HD, and various satellite positioning systems including GPS, GLONASS, and others. Notably, NFC is not available, which could be a downside for those who frequently use contactless payment systems. The USB Type-C port supports OTG, providing additional flexibility for connecting peripherals.
