What's the difference between hard covers and soft silicone covers?
Fatorder.com sells covers both hard and soft cases for Samsung r355c offered by Straight Talk, NET10, and Metro PCS.
The main difference between the hard and the soft covers is the material. In principle, they serve the same purpose however some people prefer either the soft rubber (silicone) feel over the hard plastic or the other way around.
Each case is designed to fit the Samsung r355c perfectly and offers the same openings and functional buttons so your phone can be used without interruption.
