Thank you for contactig Honor Customer Support.
Magic 6 PRO was not launched officially in Greece and most likely, the shop you bought the device from, brought the phone from another country in which the phone was released.
We recommend you to contact the shop for details regarding warranty and service, as warranty and service are available only in the country the phone was brought from. Αυτή η απάντηση μου ήρθε από την επίσημη αντιπροσωπεία. Άρα δεν έχει εγγύηση στην Ελλάδα;
