I bought many different brands of mobile in my lifetime along with Samsung The Other brands start giving problems within a year that is within warranty period or just after a year ends but that was not the case with Samsung mobile . I bought Samsung tab and resell it after 2 years without any problems . In the same way another Samsung mobile I resell after 1 years without any problem and now I have Samsung J2 Core and j7 Core with me and working smoothly without any error from last more than one year. I recommend Samsung mobiles even though little expensive than other brands.
