Samsung galaxy j7 is a mid range budget phone, its camera is very good, front flash is very good, you can take selfie in night also.If you are a hardcore gamer then you should go for it. It does not get more heated up while playing heavy games like asphalt 8, dead trigger etc.
display is very good and viewing angle is very nicebut the sound quality is not good and it also has not basic sensors like ambient light sensors.overall it is a good phone
