When connecting an external device to a mobile phone or a tablet, please keep an eye on the power supply status, and confirm whether the format of the external device (USB Type-C) is exFAT / FAT32.
Currently, the external device (USB Type-C) format that most mobile phones and tablets natively support is exFAT / FAT32.
As a result, you cannot directly use the NTFS external device (USB Type-C) on these devices.
