The chrome band around the screen is plastic, the screen itself is plastic, the back is mate rubberized plastic covered with pattern on the bottom. Overall the quality of materials is very much Samsung like nice. The phone comes in any color as long as its Black.
The assembly quality is excellent: nothing is squeaking, crackling or feeling loose. In fact, the panels fit so tight, it is a pain in the butt to take off the battery cover and you need to do it to get access to SIM card.
Measuring 4.33 x 2.08 x 0.51 (110 x 53 x 13 mm) and weighing 3.08 oz (87 g), Sunburst can be called a perfect phone size. It is however not very comfortable for use with a single hand of an average male size due to the UI buttons located very low relative to the center of weight of the phone.
On the front, besides the screen serving as a main UI control, we have three buttons: Pick Up, Hang Up and Back/Cancel. On the top and on the bottom we do not see any controls. The back side features a 2.0 MP camera without a flash as well as a speaker; the right side is used for a camera button, proprietary charger/headphones jack and Lock/Unlock button, when the left side takes care of the microSD card slot and the volume controls.
