Designed with the mission to showcase Acer's most advanced technology with its 9.9 mm slim form factor, Acer S500 is also styled with Acer's “Sleeve” DNA that wraps the device with soft and contoured surfaces and enhances handheld experience. The stainless steel receiver in the front and the Dolby speaker plate in the back are processed with micro perforation holes, which reflect the premium style and quality of the design. Attention to details are also paid on the volume button that provides both visual and tactile indication of its control functions, as well as the 3D texture on the back of the phone that creates a unique tactile sensation.
