Connectivity
In terms of connectivity, the BLU Studio 5.3 II supports Wi-Fi 802.11 b/g/n with Wi-Fi Direct and hotspot capabilities, Bluetooth 3.0, and GPS for location services. Unfortunately, it lacks NFC, which was becoming a useful feature for contactless transactions and data exchange during its release. However, the phone does include an FM radio, a feature that's been phased out from many modern smartphones, yet remains popular among some users.
