Audio and Connectivity
The audio experience on the Sharp GX15 was quite basic, with polyphonic ringtones and vibration alerts being the primary means of notifications. While it didn't feature a loudspeaker or a 3.5mm headphone jack, users could rely on downloading additional ringtones for personalization. Connectivity options were limited but included Bluetooth 1.1 and an infrared port, allowing for short-range wireless communication, which was typical before the era of ubiquitous smartphones. However, the lack of advanced positioning systems and WLAN highlighted its role as a phone focused on communication rather than a multi-use device.
