I was really disappointed after purchasing Galaxy J7 and realised that many other brands like Meizu Coolpad and LeEco provides smartphones with great specification and lower price than that of galaxy J7. It has a low pixel per inch density which is 221 ppi and does not have a full HD display which one can easily find in other smartphones within this price segment. The quality of the speaker is bad.
One may miss the call if kept in other room and the the sound is not pleasureable to hear on full volume. It does not have a LED notifiaction, noise cancellation and ambient light sensor. And it also does not have back light keys. Its better to invest in other smartphone.
