HAI FRINDS., The one of the waste and worst mobile is samsung galaxy grand prime. This is the my 1st mobile which I was use. the cost of the mobile is too much but it will not works properly. the sound reception is to bad in this mobile. this molie is easy to use but its take the too much time to open the applications. its works only 3months properly after we buy the mobile. there is no better features in in this mobile. for this cost we get the good mobile in the market.
