Design and Display
The Asus Zenfone 4 featured a distinctive build with dimensions of 124.4 x 61.4 mm and a variable thickness ranging from 6.3 to 11.2 mm, allowing for a somewhat tapered look. Weighing just 115 grams, it was lightweight and pocket-friendly. Its design was accentuated by bold color options like Charcoal Black, Pearl White, Cherry Red, Sky Blue, and Solar Yellow, appealing to consumers interested in personal expression through technology. The phone sported a 4.0-inch TFT display with a resolution of 480 x 800 pixels, delivering a pixel density of approximately 233 ppi. While not high-definition by today's standards, it provided sufficient clarity for various daily tasks. Furthermore, the display was protected by Corning Gorilla Glass 3, affording some measure of resistance to scratches and drops.
