The TF card needs to be formatted as FAT32 on the computer by yourself! ! ! (or format the TF card in Android),
Please back up the TF card data before formatting!!!
It must be formatted in FAT32 format to be recognized. NTFS format and exFAT format cannot be recognized. After connecting, you can operate the TF card like a USB flash drive.
