If your device fails to detect the memory card, please follow these steps:
Step 1: Verify Card Specifications Confirm your memory card capacity and current format. For 64GB and 128GB cards, you must use a formatting tool to convert them to FAT32 format — standard system formatting may not work properly.
Step 2: Format Your Memory Card For 64GB/128GB cards, use a third-party formatting tool to ensure the correct FAT32 file system is applied.
