The KEYone featured a distinctive design‚ combining a 4.5-inch IPS LCD display with a 35-key physical keyboard below. The anodized aluminum frame and textured back provided a premium feel and enhanced grip. The inclusion of a capacitive touch sensor on the keyboard itself allowed for scrolling and other gestures‚ adding an extra layer of functionality. While the device was relatively thick and heavy compared to contemporary smartphones‚ this contributed to a robust build quality‚ often described as "built like a tank."
