I have titled this review as my best friend because it is a budget smartphone and has all ( lump sump) necessary features. You can check the link below for description : http: //tinyurl.com/samsungj2specifications
I have been using this phone since 8-9 months and I have not yet got any of the negative feedback from my side. Its fast and smooth. One of the thing I will advice after buying the phone is, never install any RAM cleaning app which claims that it will make the phone faster. Those are just false statements. Manually what you can do is Go to Setting > Storage > and clear the Cache. This is far more better option than installing the application. I will recommend this phone because on the whole its a good phone.
