The Samsung Galaxy S Duos model, which was first released in 2013, is different from its competitors at the time. It is made without using any metal materials in its case.

Another striking point in the body structure of the Samsung Galaxy S Duos model was the rear. The matte-coated back thus showed no fingerprints or hairline scratches. The openings in the back cover were also extremely important as it is a model that can be put on and taken off the cover. Through painstaking work between the openings in the lid, it was able to withstand pressure by leaving exactly the required space.
