Design and Display
The BenQ-Siemens SF71 is designed to be straightforward and practical. Measuring 96 x 48 x 23 mm and weighing 118 grams, it fits comfortably into the hand and pocket. The phone uses a Mini-SIM and is encased in a classic black finish, offering a sleek and understated look. It features a main TFT display that showcases up to 256K colors, offering decent vibrancy and clarity for that era. The 2.0-inch screen, with a resolution of 240 x 320 pixels, ensures a fairly sharp image display at approximately 200 pixels per inch, making it adequate for viewing basic media, messages, and applications. The SF71 includes a second external OLED display with 65K colors, providing essential information like time and caller ID without needing to unlock the main screen.
