Samsung j7 is the mid range phone that was launched in 2015.The phone has a good 5.5 inch amoled display that is quite good for movies and games etc.The phone has 13 mp rear and 5 mp front camera.The image quality is nice probably one of the best at that price.
There are certain features added in this phone like theme support and ui good till now didnt found major lag.Most games on the phone is playeable but highend games like nova 3 and gta lags.The problem is that it is much big for single hand operation and also slippery.So there is a chance of dropping it.The battery also works fine.It will work for a day for casual users.
