Connectivity and Additional Features:

In terms of connectivity, the A40 offers Wi-Fi 802.11 b/g/n, Bluetooth 2.0, GPS, and an FM radio. However, it lacks NFC, which is not surprising for a phone from its price bracket and era. The microUSB 2.0 port is used for charging and data transfer, a standard feature at the time. The phone also includes an accelerometer and proximity sensors, allowing for basic motion detection and screen functionality.
