Yes, there are counterfeiters of any big brand mobile phone. Pay attention to the authenticity when buying.

1. Look at the trademark logo: The OPPO mobile phone trademark is an artistically designed English letter, as shown below:

Any OPPO logo on the mobile phone packaging box, manual, warranty card, charger, battery and mobile phone case that does not match the trademark is a counterfeit and infringing product.

Special reminder: All OPPO mobile phones currently sold by our company use this trademark in English letters and do not use Chinese character trademarks. Moreover, no words or fonts are ever added, deleted or changed in front or behind the trademark in English letters. There will be no changes. Those mobile phones with trademarks such as "CPPO", "OPPC", "OPPQ", "appo", "QPPO", "QPPQ", "oppa", etc. are all infringing products.

2. Check the manufacturer’s name, address, and phone number. The manufacturer's name marked on the OPPO mobile phone packaging box and manual is: Guangdong Oppo Mobile Communications Co., Ltd. (formerly Dongguan Oppo Mobile Communications Co., Ltd.); the factory address is: No. 18, Wusha Haibin Road, Chang'an Town, Dongguan; Customer Service Hotline: 400-7799-666.

Any product that is not marked with the manufacturer’s name, address, or phone number, or does not match the above name, address, or phone number, is a counterfeit and infringing product.

3. Check whether the warranty card is stamped. The OPPO mobile phone warranty card that comes with the machine is stamped with a red seal that reads "Guangdong Oppo Mobile Communications Co., Ltd. Warranty Seal" (originally "Dongguan Oppo Mobile Communications Co., Ltd. Warranty Seal").

Any warranty card without the red seal or with different text on the seal is a counterfeit and infringing product.

Note: The warranty card is separate from the instruction manual. The warranty card is a separate booklet with the address and telephone list of the nationwide warranty points for OPPO mobile phone products.

4. Check whether the "OPPO" trademark appears on the startup screen. OPPO mobile phones will display the "OPPO" logo on the screen when they are turned on; while some counterfeit and infringing products do not display it.

5. Check whether the machine has an IMEI number. OPPO mobile phone series products have the same set of IMEI numbers pasted on the packaging box, mobile phone body and warranty card. Each mobile phone corresponds to a unique IMEI number. The IMEI numbers of different machines are different; anything that does not match the above characteristics is Counterfeit and infringing products.

6. Check whether there is an electronic warranty card registration function. All OPPO mobile phones have an electronic warranty card registration function. Any OPPO mobile phone without this function is a counterfeit product. Consumers can also log in to the mobile phone authenticity verification website of the Ministry of Industry and Information Technology to verify the authenticity of the mobile phone: END
