The USB disk was able to be used before, and now it doesn t respond when it s plugged in to the phon

This is because the file system of this USB flash drive is wrong.

Mobile phones, by default, can only recognize the file system of FAT32, if the USB flash drive is formatted as NTFS or EXFAT, it will not be recognized.

Workaround:

1. Set the U drive to FAT32.

2. Or install the ntfs mount plug-in after rooting the phone. This trouble, not as good as the first one.

The format is not recognized, export the file, the computer reformattes the USB disk, and then copies the file to the USB disk.

The mobile phone supports the OTG function, but the quality of the OTG cable used is problematic, resulting in the inability to recognize the U disk and not display the content of the U disk; You can try to reconnect it with a *** OTG cable. 3. Poor contact between the mobile phone and the OTG cable, the OTG cable and the USB flash drive will also cause the mobile phone to fail to display the contents of the USB flash drive, so you can try to plug it in again.

4. If there is a problem with the mobile phone system, the connected USB flash drive is not displayed, you can restart the mobile phone to solve it; If necessary, you can consider restoring the phone system to factory settings or upgrading to the latest version.

5. The hardware failure of the mobile phone causes the connection to the USB flash drive to not be displayed, such as the failure of the charging port, the failure of the motherboard chip, the failure of the processor, etc., which needs to be repaired by contacting the after-sales service of the mobile phone to solve it. 6. Check whether the U disk format is FAT or FAT32, if it is FAT32 on the phone, it may not be displayed, sometimes you need to format it as FAT.

The mobile phone plugged into the USB flash drive does not respond to the solution.

The mobile phone needs to support the OTG function, but this does not mean that you can directly insert the hard disk into the mobile phone to read the data, and you have to connect the mobile phone and the hard disk through a special OTG data cable for data transfer.

You need to prepare an OTG data cable, plug one end into the hard drive, and plug the other end into the mobile phone. You can transfer data to each other.
