I bought this before 2 months ago.and recently I sold it in half price of it.do you want to know why? here is my 60 days experience with j7 prime.
First of all its no for game or performace lover.because its hanging too much without any cause.the second thing camera is not as I was expected.battery quality is poorest.
Sound reception is quite good.
Its not user friendly at all.
I really dont like its style and design.it is really like old style.
I dont find any special other features on it.
It looks really poor and I dont feel comfort when I using it.
If you really love performance on phones and loves to captures moment on camera then it is not your value for money.
