Audio and Connectivity
The device features a loudspeaker and retains the traditional 3.5mm headphone jack, the preferred standard for audio enthusiasts who value wired connections. Communication features include Wi-Fi 802.11 b/g/n, Bluetooth 4.1, GPS for navigation, and FM radio—a nice add-on for radio listeners. However, it lacks NFC, which limits its function with certain wireless payment systems. The inclusion of microUSB 2.0 with OTG capabilities is adequate for the device's needs.
