Hi, friends. I bought Galaxy J2 6 in March 2017. It is still reliable, comfortable and handy.
It is having super AMOLED full HD capacitive touch screen with 16 million colours and 294 PPI pixel density.
It works on Android OS version 6.0.1 Marshmallow. I found no hazziness while running this smartphone as it works on SC 8830 Spreadtrum processor which is not new processor like Snapdragon but still works very good. Its battery backup is not so good as it has Lithium ion 2600mAh which get down in a few hours .
The other thing which I do not like about this Smartphone is its heating it heats up while running heavy apps. So, I would recommend it only for those who searching a smartphone for business purposes.
