How to tell whether a Samsung mobile phone is a parallel product or a refurbished machine?

Dear Samsung users, due to the large number of knockoffs, parallel imports and cloning machines on the market, it is impossible to accurately identify the authenticity of mobile phones by serial numbers and IMEI numbers. 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 be repaired if it has performance failure within the warranty scope. If it can be repaired, the machine is a genuine Samsung licensed product. For the specific location of Samsung Service Center, please click the following link:.
