Samsung SCH-X430



The Samsung Anycall SCH-X430 is a high-end flip phone released by Samsung specifically for SK Telecom in 2002. It is one of the early Samsung phones with a colour screen, boasting an active-matrix TFT display with a resolution of 128x160.

The SCH-X430 is commonly seen in silver or white, although the plastic casing of the white model is prone to yellowing due to age and the type of plastic used.

Being a high-end phone in 2002, it boasted a heavy feature set for the era, which included a TFT colour screen, 40-note polyphonic ringtones, mobile wallet, roaming mode, and much more.
