Samsung D428 Sound and Connectivity

Sound and Connectivity

Audio capabilities of the D428 included downloadable polyphonic ringtones and a built-in ringtone composer, but it lacked a loudspeaker and a 3.5mm headphone jack, which restricted sound output options. Connectivity was typical of early 2000s devices, with support for GSM 900/1800/1900 2G bands and GPRS Class 8. Notably, it did not feature Bluetooth, WLAN, or GPS positioning, reflecting the limited connectivity options available during that period. An infrared port was provided for data exchange, which was somewhat useful for its time.
