I think samsung company is making phones so that they can only complete their warranty period . I had two samsung phones and one of those was samsung core2 and after the completing 2 years that battery was totally destroyed . It was not able to work when it was not charging and this created great difficulty for me . And at last I bought an apple product which was comparatively much better than samsung product . Hence I am warning you from buying such bad phones. It can also happen with you so please be careful and dont fall in these traps.????????????????????
