Hello friends today im talking about samsung galaxy star advance duos. In this mobile phone I face many problems. In starting this mobile phone give very nice response to me but day ay after day I realise its problems like low RAM very low space in ROM and the problem of hang. After 1 year samsung galaxy star advance is very much hang many times while Im chatting and doing work in this mobile phone. So that it is why I suggest you friends dont purchase samsung galaxy star advance because I have very bad experience with it.
