Samsung Galaxy J7 6 model is far better than older model of Samsung Galaxy J7. Previous version it has 1.5 GB Ram, but in new version it has 2 GB Ram. In previous version it has 3000 mah battery, but in new version it has 3300 mah battery. Previously it has 1.5GHz Octa Core processor and now it has 1.6GHz Octa Core processor. This phone is also lighter than previous version. It also looks good from previous version. The price is slightly high of Samsung Galaxy J7 6 model from older Samsung Galaxy J7 model. But I expect that after few months the price will drop down. So if you have budget then you go for Samsung Galaxy J7 6. Otherwise wait for few months for droping down it’s price.
