How to check the origin of Samsung on the Internet?

Dear Samsung users, the origin of Samsung mobile phones listed in Chinese mainland is: Tianjin, Huizhou and Shenzhen. Because there are knockoffs, parallel imports and cloning machines on the market, it is impossible to accurately identify the authenticity of mobile phones by serial number, IMEI number and mobile phone origin. If you want to identify whether the machine is a licensed machine listed in Chinese mainland, please take the purchase invoice, warranty card and the machine to the nearest Samsung service center and ask the service center staff whether the machine can enjoy the warranty. If the machine can be guaranteed, it is a genuine licensed Samsung machine. It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order. Please bring your machine, invoice and warranty card to the service center you booked on time. If you have any comments, suggestions and comments, please click: support.samsung.com.cn/survey.
