J7 Pro is one the best mobile that I have used before. I bought it INR 20700 last month. It comes with a 5.5 SUPER AMOLED FULL HD display which is a superiour quality of viewing and enbeled with Samsung own produced Micro Chip Exynos 7870 a 1.6GHz octa core processor which make it more power efficient with 3GB DDR3 RAM makes it more powerful. Nice balance of Hardware with MALI T830 a powerful GPU. It can be upgraded with 256GB external storage and 64GB of internal storage. About the primary camera it comes with a 13MP f/1.7 lens sensor makes it more workable in low lighting condition throug a accurate focus and videos. And the 13MP secondery camera also comes with a LED Flash with a shuttering focus which provide us a instant selfie with good colour balance. It has all the mecessary sensor that are used in daily life. The finger print is improved than j7 prime and new gyroscope sensor enabled it with VR headset. At the last about the battery backup the 3600MAh battery can be used for atleast over a FULL DAY USE backup easily. I have enjoyed a good experience with no heating and No lagging issue.
