I am using j3 pro during 3 months
The sound quality of j3 pro is not good
It is also very hard to use
It remain hang some times
The power of j3 pro is not enough so the battery drain fast
The body shape of j3 pro is not too good
It is very slippery .
It is not easy to use j3 pro
So this smart phone is not durable
And it is costly that its features.
