Samsung galaxy j2 ace is not bad . But its ram is very lowv. Its ram is 1 gb.and also I got some problems with is speaker . The person from other side cant understand what we are talking. And also its internal memory is too low for its price. Cool pad have the better feutures can have the better feutures then this. And its ram also 3 gb.and aslo the mobile struks sudenly , then we have to switch of the mobile and restart . Display quality is very poor. And this mobile is not for online users because inthis mobiles network is not good.
