While Micro SD cards 128GB or lower are supported, some manufacturers may not follow the same standards for file storage and transfer. Below are several troubleshooting steps to resolve this issue:
- Remove and then re-insert the SD card.
- For a new SD card, please make sure that it is formatted (there will be on-screen instructions).
- If this does not work, try another SD card.
- If the issue occurred only after a specific app was installed, uninstall the app and try to use the SD card.
