The Samsung Galaxy J6 (2016) was made official last month, however we had no idea when they will be available outside of China. There were some reports, but all of them were unconfirmed.
Samsung Spain has the device listed on its official website for €299.
The phone specs looks like this:
fullHD display
3 GB RAM.
Which is strange that on the Spanish website the specs looks diffrent: only HD resolution and 2 GB of RAM. On the other hand, we have Marshmallow. Maybe it is just a bug that will get fixed on the site.
