Samsung J2 is a good phone . Many of my friends are using it . Since it is a normal budget phone there is not much functions compare to other samsung then too this phone is quite satisfying phone for people who need a normal budget phone .
It screen quality is good . With good sound quality and no issues of hanging .so overall its a good phone . It depends on the user that how he use phone . You should update software time to time and should not keep the memory full to be safe from hanging issue .
