I have bought this phone in last month since then this phone is running good. Camera Quality is good.Actually Front camera is much better than the other J7 series.Battery Performance is at par level, usually last for 8 hours on running.But the main problem is the processor.
It is not a snapdragon processor like another phone like Lenovo, Mi, etc.So If you are a gamer than I would not recommend this. For gaming phone you can opt for Lenovo p2, Mi Note 4, Moto g5 plus.I am using this phone for its camera quality.
