[DETAIL] AFTER-SAlES ISSUES: * The mobile terminal cannot recognize it. Check whether the OTG function of the phone is turned on, then plug it in and use it. If you still have questions, you can contact the seller's customer service and they will provide you with a better solution. *The memory capacity received does not match "for example, if you buy 64GB and insert it into the computer, it will show 58GB" The difference in product capacity is explained in detail in the detailed description, which can be browsed carefully to avoid misunderstandings. This is a calculated difference between the manufacturer and your computer, please google "memory card capacity"for more information. Your PC means 1GB = 1073741824 million bytes, while the market defines 1GB = 1 billion bytes. There is a certain difference between the displayed capacity and the nominal capacity of flash memory products. Therefore, the 64GB USB flash drive does not actually reach 64GB, and most of them are around 58GB. This is within the normal range. * The PC version cannot be used Please try switching the USB format to NTFS format. First plug the USB into the computer, then right-click, select Format, and switch the format to NTFS. If you still have questions, you can contact the seller's customer service and they will provide you with a better solution. * Slow reading and writing speed The reading and writing speed of a USB flash drive is related to the USB interface of the computer, the size of the copied file, the format of the USB flash drive and the computer operating system. Under different usage conditions, the reading and writing speed will vary. This is a normal phenomenon during the use of USB flash drives. KIND TIPS: If you encounter any problems, you can contact the seller's customer service first, and the customer service will provide you with a better solution.Thanks [ATTRIBUTES] - Hign-concerned Chemical: None - Application: High Speed Read and Write,MOBILE PHONE,Tablet,NOTEBOOK,Tachograph,Camera,Monitoring,Speakers,Digital Devices,Robot,UAV,File Storage,others - Application Performance Class: A1 - Hign-concerned Chemical: None - Application: High Speed Read and Write,MOBILE PHONE,Tablet,NOTEBOOK,Tachograph,Camera,Monitoring,Speakers,Digital Devices,Robot,UAV,File Storage,others - Application Performance Class: A1 - Video Speed Class: V10 - UHS Level: U3 - Class Level: C10 - Package: Yes - Read/Write Speed: 60x - Type: SD Card - Brand Name: SHANDIAN PAY - Origin: Mainland China - Application: High Speed Read and Write,MOBILE PHONE,NOTEBOOK,Tachograph,Monitoring, - Read/Write Speed: 10MB/S - Maximum write speed: 12MB/S - Maximum reading speed: 30MB/S - RAM: 8GB 16GB 32GB 64GB 128GB - Colour: White flash card
