Display
Equipped with a 2.2-inch TFT display, the S5500 Eco provides a modest visual interface with support for 256K colors. The resolution of 240 x 320 pixels results in a pixel density of approximately 182 ppi, which was standard for entry-level phones of that era. While the screen is adequate for basic tasks like messaging and calls, it falls short of delivering the high-resolution experience that modern smartphones offer.
