This is not an original Samsung S3 Battery. This is evident, however, only at accurate comparison with the battery of S3. The inscription of the battery, for example, differs in the row "MADE IN CHINA / FABRIQUE EN CHINE" - here is when you original battery supplied "MADE IN KOREA, ASSEMBLED IN CHINA". In addition, the inscription on the printed image slightly anderst looks (coarser the resolution). Also, I could firmly tellen that the fit is not the original corresponds to because you have to press the battery purchased here a little harder in the mobile phone so that it is used.
