Good Display, Good Performance, FRONT FLASH, Good Camera, Good Battery, Wonderful Headphones

Sound is Average, look is Decent (Not Cheap, Not Premium), No Auto Brightness Sensor.

In Short, Go for it. TOTAL VALUE for the price

Display 10/10
Speed 9/10
Camera 9/10 (Though not as good as other 13 mp camera from high range samsung phone)
Battery 8/10 Battery Back up is average though no hitting issue

Over all performance 9/10

I have used this phone. Look wise it is good but my concern to buy this phone was camera and brand value of samsung. So i will say that i am not fully satisfied with the back camera performance. Front is excellent but back camera is not good as compare to other 13 mp camera phones it looks like 8mp only. battery backup is 1 day with normal usage. I just say that it is good phone but not the best one from samsung.

pros:

DISPLAY 5/5 : display is very sharp ...FHD videos looks quite good.
SPEAKER 4/5 : speaker is not so loud, but its a decent one....
PERFORMANCE 5/5: response is pretty quick....high end games run smoothly without lags.
BATTERY 5/5: battery is really good nd no heating issues while playing games...on normal usage it will last 1 whole day( or even more days on stand-by) nd it charges up quickly.
CAMERA 4/5: front cam is really good with front led flash. rear cam is just ok. pictures ar...

Excellent

I am using from August 2015 to till now.
I didn't find any Complaint in this phone.
Now after updating the software to Marshmallow it's been little slow but that is too ok.
Cheap and best

Pretty nice phone with good features and does not discharge soon on internet connectivity,
didn't find any heating issues as of now but there are plenty of auto updates running during initial connectivity to internet

Samsung J5 I bought 7 months back works well except for the 8 GB internal memory. This internal memory 8GB is so inadequate that even the regular updates (apart from the app updates) cannot be made. Even after deleting many of the apps provided by Samsung, it always shows "storage space running out". Worst memory management by Samsung. Except for this downfall, all other features are good.

The main draw back is getting memory full easy all the apps are installing on Phone memory and the size of the Apps are very high as compared to other mobiles ..Facebook consuming 300mb memory while installing itself..
