Although samsung is very gud brand but mobile are too expensive regarding their specification j7 prime has only 3gb and 16 gb internal and many other brands give this at half price so I dont think it is gud choice to buy at this price if u compare it with brands like mi oppo vivo u get too much better phone than this lets take example of 3s prime whics has 3gb of ram snapdragon processor 430 32gb internal and gyroscope sensor at half price than j7 prime if I compare battery than 3s has 4100 mah and j7 prime has only 3300 mah battery
So I dont think it is gud choice but if ur a fan of samsung than u can buy this
Gud luck
