As we know samsung is a good company. Some time its good or sometime it is bad. talking about j2 6 yes it gives 6.0.1 Marshmallow, 5 inch display, 1.5 GB RAM, 8 megapixel in rare and 5 megapixel in front camera. it has good photo quality. but the primary cant record videos in full HD. NO USB OTG support. Does not come with first charging. sometimes it got hang at the time of playing YOUTUBE video. I personally suggest dont buy this phone. As compare to price it does not give much specification and most of the time it got hang.
