Display
The Nokia 603 features a 3.5-inch IPS LCD screen, a size quite common for entry-level smartphones from that era. Despite its modest screen-to-body ratio, it offers vibrant visuals thanks to the Nokia ClearBlack display technology, which enhances screen visibility outdoors by reducing reflections. The resolution of 360 x 640 pixels delivers a pixel density of about 210 ppi, providing a sharp enough experience for everyday use.
