After so many disappointments from Samsung, the all new galaxy J7 is the best in its class
Comes with 5.5 inches Super AMOLED capacitive touchscreen, I am using my J7 on android 6.0.1( Marshmallow) and it runs very smooth on this device, thanks to Octa-core processor and 2 GB of ram, graphic unit is Adreno 405 which is very good for gaming
Played heavy games on it ., it supports microSD, up to 256 GB, coming to the camera its also amazing, front camera is too good with front flash which is a much needed feature for selfie lovers, led flash is also very powerful best for low light images and low ligh video recording.
Yes the speakers should be more powerful as compared to other phones like mi note 3, leeco and other this budget mobile phones, it comes with 3300 mah battery. And gives amazing battery backup guys far better than many android mobiles.
