What to do if the phone cannot recognize the SD card?

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.
