I used samsung galaxy j2 from 2015 and I still using it approx 2017 and after that my mobile was out of order and then I through it in dustbin.
It sound quality too bad because when I was listened song in this mobile then its started making noise and very irritated sound was hear with song. And you talk with anyone suddenly its started snort.
It behavior is so bad because after 2-3 months its started hanging. Because of this you can not run your mobile properly.
Its body is so fatty because of this its weight is very heavy and because of this its looking so bad.
It is so worst mobile. Its battery backup is so bad its only run 1-2 hours after fully charged thats why its battry backup is so poor.
If you buy this mobile then you waste your mobile. This mobile is fully wastage of your money.
