I personally using this phone.It never hangs it never lags. It comes with a 3GB RAM and professors are fabulous. Gaming experience is nice.Now a days battery life is a big factor it comes with 3300mAH it lasts for 1.5days.its comes with a slim design and its best part is its black mirror finish on its black variant.Samsung Galaxy J7 Prime was able to handle almost everything we threw at it. The octa-core processor performed really well and we had no complaints. It handles games like Dead Trigger 2 with ease. Multi-tasking on the J7 Prime was fine and apps launched quickly.
