It is the worst mobile I have ever bought.This phone hangs too much.I can’t operate any application smoothly.When I bought this mobile for at least 4 months it work nicely but as the Months passes It became impossible for me to access the applications.I was using samsung knox application and whenever I used to open that application mobile used to hang every time.My J7 was worst than my brothers J5.Then it became very important for me to change my mobile.
When the mobile was new it worked very smoothly.but afterwards everything goes worst.
