Samsung galaxy j7 is a very good phone it is having a 13 mp camara best than other phones it comes with lolipop android version it is having volte so you can use jio sim in it and believe me it’s front camara is better than iphone 6s it never hangs & lags I mistakely throw it from about 6 feet but it does’nt break and its touch is superior it is 4g phone so you can use fatest internet .
thanks
