It also comes with Wi-Fi 802.11 b/g/n, Bluetooth 3.0 with A2DP, NFC for easy pairing and transactions, and GPS with A-GPS assistance, making it quite capable for connectivity on the go. The inclusion of USB On-The-Go via microUSB 2.0 is a bonus, enabling the device to connect with other USB peripherals.
