Samsung Galaxy S Duos 2 S7582 is not goof mobile phone and in this phone battery backup is not good . Its features are not so good as compared to now a days smart phone devices since it becomes old one it worked very fluent and flexible at the new condition. But after 5 months of use battery problem and over load problem occured due to less space provided with less RAM. This phone battery backup is not satisfied and its display also very poor quality. Many applications are not supported in this phone.
Overall this phone is not worthy.
