Hello, I bought today from Evomag a Samsung galaxy j4 and a Samsung galaxy j6. All good until we released j4 and found that absolutely all the information and menu of the phone are set in Chinese lb. Well, I'm sorry but I do not know this language and I'm wondering there should not have been any instructions to set a lb as much as known, for example, at least English. I tried to contact the company and nothing. Hard to find
How do we do? How do I use the phone do not mind?
