My friend bought samsung j7 before one year ago. And it’s main drawback is hanging problem. Sound quality is poor while speaking the person and low quality sound. Loud speaker also same problem. Back camera 13megapixel is average and front camera 5megapixel is capturing good images. Design is looking stylish. Mobile body material is very delicated. So handle with care while using the phone. Processor is good. But heating issue while playing the heavy gaming apps. Other wise its budjet phone under 15000/-. Over all it’s average performance, so go for samsung galaxy prime.
