Display
Equipped with a 2.0-inch TFT screen capable of displaying 256K colors, the S81 offers a modest visual experience. Its resolution of 176 x 220 pixels results in a pixel density of approximately 141 ppi, which was quite typical for the period but clearly lacks the sharpness and clarity expected in modern smartphones. The screen occupies roughly 24.1% of the body, indicating a design focus that's more on functionality than screen dominance, which differs greatly from today's design trends.
