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.
