The J7 set is very smooth to operate.both the Camera, processor, battery back-up are wonderful. Good worth for money. Only set back of the set, what I feel, is too much heating problem.
After 5-6 minutes of continuous operation, the set will start heating. Also Ring Tone sound is also very low.
One major issue, I purchased J7 on mid April-2016. After 2 weeks, it was notices that the 1st SIM slot is not working with a particular mobile operator. Rest are working. When I was visited my nearest Samsung Service Center, they also surprised about the problem. NO SOLUTION FROM THEM. I can put 3.5 out of 5
Budget smartphone from Samsung with latest android marshmallow 6.0.1 best part of this phone is that it doesn’t heat up during extended session of gaming like many other phones in this price segment do overall very good package in 16k with good after sales service from Samsung as we all know.
