Samsung j7 is a damn bad phone because even if it has android marshmallow , its RAM is only 1.5 GB which does not support android marshmallow so the chances of hanging are more and battery is only of 3000 mAh which is not good and will have short term battery life .
The secondary camera is also poor with 5 megapixel . So the phone does not fulfil our needs and therefore it does not have good value for money.
