Galaxy J7 is a typical samsung device however its comparitively low priced, breaking the samsung tradition.Galaxy J7 has an amazing battery life, of upto 8hrs of usage, a good call quality, excellent and speedy camera, neat interface and a good build.
However its only suitable for those who prefer to call and watch video( or games) only.
Considering its competitors, they are offering a bettee device around Rs5000 cheaper.Like Redmi Note 3.J7 also lacks fingerprint sensors, while Note 3 has it.Note 3 also has a bettee life.
J7, however of its cons, performs well in its pros section.Its fluid, has a good memory speed, vert fast camera and a good display.But instead of getting J7( 2015 edition) I recommend to opt in for J7( 2016 edition), as its more updated.
