Hey guyz I m personally using this phone so I faced many problems in this phone.Ok lets start Many users faced the problem of screen binkling with yellow light when u decrease the brightness level and when I consult about this to someone he told me that many j7 users facing this problem and dont think the original screen is going to be cheap!. SECOND It has 1.5 gb ram which is not suficient for 16gb rom in my opinion. Due to this my phone hang many times. Third- If you r purchasing it u should purchase a gud earphones first because sound quality in j700 is not so good.
