I am using Samsung Galaxy J5 since year 2016 and till now I founded that its a nice product which offers a 5 inch Amoled display, 1.5 GB Ram, Dual Sim Support, Snapdragon 410, Adreno 306 GPU, Micro SD Support up-to 256 GB, 13 MP rear Camera with f1.9 aperture and 5 MP front Camera with f2.2 aperture, Dual flash etc. The phone feels nice and Stylish in hands and also its very light in weight only 146 grams but it skimps in certain sensors such as Step-counter, pedometer, GYRO sensor etc. Other than this the most annoying thing which I found is the internal storage that is only 16 GB which I think is not satisfactory considering the price point of the product, also the battery life is very less i.e. only 2600 Mah so every now and then I have to run to find my charger or power banks, sound quality is also poor and very low . Hence I would recommend the viewers that if you are planning to buy this product than please dont go for this one rather than you can buy other good mobile phones such as MI NOTE 4 in the same price point.
(NOTE; Here I dont favor any of the Brands such as REDMI but this is my personal review so please dont take it as a bias review)
