I tell about galaxy j7after seconds day of buy. J7 is very stylish smart phone, there is no lags on this high performance phone. 1.5gb ram is recommendation for smoothly performance. 16gb internal storage is very useful for app & high range game installing. It has 13mp camera which is too good overall it take full hd recording & 5mp front facing camera is awesome for selfie.
Battery backup is upto 15 hrs talktime and web surfing 8-9hour.I not check 4g connection because of our area have not in 4g coverage, 3g performance of this phone is awesome. Overall this phone is very good for purchase.
