Dear all Samsung Galaxy j2 ace product better h depend karta hai ki ap use sahi se kar rhe hai ya nhi nhi to this product buy few day after purchased right no problem and always good battery backup and iski diplay bhi 5 inch ki hai hd hai. Main kahta hu ki samsung ka koi ek hi esa products hoga jo ki client ko problem face karni pad rhi hogi. Nhi to mere pass bhi Samsung Galaxy j2 2015 model hai 1year ho chuka lekin koi problem nhi a rhi hai. Battery back up bi best hai. I suggest you ap Samsung purchased karo lekin shop se because online mai mediator pta nhi kya bo sahi products de rha hai ya nhi. So dear all please my thought that ki apke paise vashul ho jayegi jab ap ise chalayenge. Thank you
