I think every mobile is good but mobile; s RAM is lower than samsung galaxy j7 because this has1.5GB RAM.The reason of mobile hanging is RAM.if RAM is lower nearly 700MB RAM mobile will hang.but believe me friend this will not hang.this mobile goodness who know that master of internet.you can do enything in internet technowlgy.nearly every mobile not sopport everything.but this mobile will sapport every function of programme.buy this mobile if you want to know everything as like enternet, study, art programming, online business etc but don, t buy if you only want get entertainment only from this mobile because this has many function.
