As a J5 user I have many complains about this phone but first let me give its a little review.
I bought Samsung J5(2016) last year and its the worse budget phone ever. Considering its alot expensive price which is 13k in India and 25k in Pakistan the specifications under the hood is alot worse than what it looks from outside.This phone is just for looks and glamour and nothing else as expected from samsung. Samsung mostly ditches features and sensors in its budget phones whereas many companies like xiaomi or huawei provides much better specs in lower price.
Below is the specification of this Phone:
A 5.2 inch 720p AMOLED display(282 PPi)
Aluminum frame but plastic body
Snapdragon 410 Quad-core clocked at 1.2 GHz Cortex-A53 with Adreno 306 GPU
2GB RAM and 16GB ROM
A primary 13 MP(f/1.9, 28mm) camera with LED flash and a secondary 5 MP, f/1.9 also with a LED flash
WLAN:Wi-Fi 802.11 b/g/n
Bluetooth:4.1
microUSB 2.0, USB On-The-Go
sensors:Accelerometer, proximity
And a removable Li-Ion 3100 mAh battery
The things that I loved in this phone:
AMOLED screen on this device is very crispy and to the point but having a 720p display ruins it all.
The metal Frame around the phone makes it look very premium and it feels good while holding it.
The flash on the front camera is nice but it doesnt work with 3rd party apps
The things that I didnt love:
As this phone has an entry level processor its performance is poor and lags alot in most applications.
The 720p display is old fashioned and should have gone for 1080p like xiaomi did with redmi note 3.
No fingerprint reader, and most of the sensors are missing like gyro etc.
Camera is alot noisy specially in low lighting but its just fine in day lighting.
It has a single speaker at the side of camera lens which doesnt produce very loud sound and is very average.
The battery is average but sometimes it doesnt even stay for a whole day, battery timing while surfing is 10 hours but while watching any video or movie is 5 hours.
Benchmarks:
As it has snapdragon 410 it performed poor and scored 27k on antutu benchmark considering its not a 10k phone.
Final word: I wont recommend this phone as its performance is not that much special and there are many other great phones in xiaomi or huawei to go for then this phone.
