Sorry, the mobile phone model you inquired about is not listed in Chinese mainland for the time being. There is no information about this machine.
At the same time, in order to ensure the rights and interests, it is recommended to buy Samsung genuine licensed products listed in China.
If you need to buy a Samsung mobile phone/tablet, it is recommended to buy it in a regular mobile phone shop.
For example: Samsung designated stores, Samsung shopping malls, large shopping malls and so on.
