Why buy Original?... Samsung Original Parts...This is an original Samsung Battery cover...Why Original?.. The battery cover is made from a strong plastic, however, the outer surface is specially treated with a rubberised finish. This is the main difference between the non originals (fakes or copies) and the originals. The non originals are black plastic ONLY and the original version has a rubberised matt finished. If you don't fit an original battery cover to your phone then it may look a little odd or shiny. If you want your battery cover to last and look as it should then always buy original, there really is a huge difference.
