The 4.0-inch WVGA screen at 480×800 pixels with a pixel density of 233 PPI, is decent for the price. The viewing angles are just average and the sunlight legibility could be better. Since the phone uses a capacitive touch screen, the display is sensitive and the touch response is good. Since the display is glossy, it is prone to fingerprints. Samsung has changed the egg-shaped design from the Galaxy Star to a better design. Even though the Star Pro has curves sides, this looks more like other mid-range Galaxy smartphones.
Above the display, you have an earpiece with chrome finish. You can see the Samsung and Duos branding below the earpiece. Lack of a front-facing camera is acceptable considering the price tag, but Samsung did not include an ambient light sensor or a proximity sensor in the phone. When you make a call, the screen doesn’t turn OFF to save the battery, but actually locks itself. Due to the lack of ambient light sensor you have adjust the brightness of the screen manually in brightly lit conditions to view the display content properly.
You have Samsung’s signature hardware home button below the display with a chrome finish around it. On either sides, you have the menu and back buttons. These are not backlit and doesn’t offer haptic feedback when pressed. These touch buttons make Samsung’s signature water drop tone when pressed. This could be turned OFF from the sound settings.
