Samsung galaxy j7 nxt is not much good phone. there are lot of problem you faced after buying of 5 to 7 month. some time phone going to be hang very badly and not working fluently untill you restart the phone. camera quality is good enough but sound reception quality is not so good. phone volume is very low. this phone is not much user friendly. some time this phone gives a lot of heats during charging process and uses of internet. its design is also not bad. ram of phone is very low that’s why it takes a long bit of time to process the higher version apps.the battery backup is also not good.
