Sound and Connectivity
The phone is equipped with a loudspeaker, and users could indulge in downloadable polyphonic and MP3 ringtones, which was a popular feature back in the day. However, the lack of a 3.5mm audio jack could be considered a drawback, especially for users who relied on conventional headphones.
On the connectivity side, the A780's support for Bluetooth 1.1 was forward-thinking, allowing for file transfers and wireless headset connectivity. GPS positioning was another significant inclusion, aiding navigation tasks, though the absence of WLAN limited its Internet accessibility to GSM networks using GPRS and EDGE. The proprietary USB connection was standard for this period, albeit less flexible compared to later micro-USB or USB-C standards.
