If your phone cannot recognize an external SD card and you cannot see any data on it, please follow these troubleshooting steps:
1. Try using a different SD card or place the SD card in another phone to see if it is recognized, which helps rule out issues with the SD card itself;
2. Ensure that the phone’s system is updated to the latest version. If not, please update the system and check if the issue persists;
3. Check if you have made any recent changes or actions before the issue occurred, such as updating the system, installing certain applications, rooting the phone, or downloading a third-party security APP;
4. If you have made any of these actions, it indicates a local system issue. Please restore the system to factory settings and retry. If this does not resolve the issue, please contact the local after-sales service center for further assistance.
Note:
It is recommended to purchase the SD card from a reputable manufacturer to ensure data security.
