I am using galaxy J7 from last one year.it is such an unsatisfying phone for me
It has only 1.5gb of ram due to which phone does not work smoothly
It has a flash in front facing camera due to which photos becomes blur sometimes
Auto focus also doesnt work properly abd colour balance is too bad in both camera
( Front and back)
Speaker sound was good at starting but now it became less automatically , so I want to use headphones for listening music, which causes problem and irritation
It has ultra data saving mode which is totally useless, it reduces speed of internet
Battery backup is not so good and brightness
Of screen makes irritation in eye
Design of this phone is so smooth that many times my phone fells down from hand due to such smooth surface and holding grip is not so good
Finally I advice you not to buy this phone at such a high cost
