Hii friends after looking for many phone I admire j7 and bought it since january 2016. J7 it function very well as some romours said samsung defect is hang . till now nothng happn to my phone , compare j7 better thn iphone 4s because the function is more which are dual sim in j7 , 13 mp camara with flash , secoundary 8mp with flash too . But one advice do not upgrade software as your ram may be lowered . This j7 come with 16 gb internal storage and ram 1.5 gb . its excelent phone ever recived happy and satisfied with the product of j7 . Suggested phone to those who want to buy mobile phone and are still confused
