Its a nice phone available in 15k range. Samsung has put their efforts to reach every person to get a best and bigger smart phones at affordable price.
I was using samsung S2 before which stopped working last year and I didnt have much budget to buy any expensive phones. The only phone came to my mind is j7.
According to me, this is the best phone one can get in this range. After I bought this phone, most of my family members and friends bought this phone. Here are few pros and cons :
Display : 5.5 inch super amoled display which is really good for watching videos and movies. The viewing angle is really good.
Camera : 13 mp back camera and 5 mp front camera with led flash on both sides is really good for taking selfies and photos even in the dark.
Battery: 3000 mAh battery is really good enough to use it for 2 days along with the data usage
Memory: 16 gb internal memory and it can be extended upto 128 gb
Simple user interface
Comes with 1.5 gb ram and 1.5 ghz octa core processor which is good enough for gaming.
Cons:
Speaker is not good enough.
Some sensors are missing like magnetic sensor etc.
