I used this phone from 10 days. I bought this from online shopping site amazon. advertised this phone by quoting that this is the slimmest phone ever and this is the only good thing about this phone. Other than this fact there is nothing good about this phone. This phone has terrible sound output and the interface is not at all good. This phone starts to give you problems after an year. Major problem which frequently occurs with this phone is that it always keeps on hanging. Sometimes it becomes very difficult to figure out the problem because of its complicated interface. Other than this the camera quality of this phone is atrocious. Other tan the looks of this phone there nothing in this phone that you should even think of buying this phone. It is a total waste of money. You can get better deals than this on phones of other brands. Do not buy this j7 prime.
