Display
A hallmark feature of the Nokia 6600 Fold is its OLED screen, measuring 2.13 inches with a resolution of 240 x 320 pixels, resulting in a decent 188 ppi pixel density. The display, though small by today's standards, was quite impressive with its ability to render 16 million colors, providing vibrant and clear visuals. It also includes a second external hidden OLED display (1.36 inches) with a resolution of 128 x 160 pixels, which was quite a clever addition, allowing users to view notifications, time, and call details without flipping open the phone.
