J7 duo is one of the best mobile by samsung though it is not so perfect .
I’ve done a comparision of thiz phone with mi a1 . of the camera ofcourse and this mobile is very good this mobile come’s with bokey mode or potrey mode wich you would probably expect the mode is available both in front came and in back. battery also last easyly for 5-6 hour while you are using youtube battery is good i’ll say it has 4 gb ram and 32gb internal memory which is not much. I got it from electronic shop in gangtok at 15k and its a fair price for mobile with this function
