Unfamiliar contacts in a notebook

Unfamiliar contacts in a notebook
Contacts were lost completely, instead of them people from all over the world who were unfamiliar with me, indicating their addresses, phones, mail sonymobile.com ... What the ...? I'm not familiar with them!

Незнакомые контакты в записной книге

Пропали контакты полностью, вместо них незнакомые мне люди из разных стран мира с указанием их адресов, телефонов, почты sonymobile.com ... Что за ...? Я с ними не знаком!

My phone is new. I need warranty.

Well, it looks like you were giving the phones with the demo mode activated, that's why I asked you to type that code to disable it.

Did you accept the warning message?

I've been using this phone since February 2018. The problem only appeared yesterday.
The same problem with the son's phone. He has sony xperia xz. I don't think that both phones xz1 and xz became with demo mode activated in one day.
