Before taking drastic measures, perform these initial checks to determine the cause of the failure:
- Check the wire: Connect your phone using another USB cable that you know works well.
- Try another USB port: If you are connecting your phone to a computer, try different ports to rule out any faults.
- Check the mobile USB port: Make sure there is no visible dirt or debris that could prevent connection.
Reboot the devices
Un reboot may resolve temporary software issues on your phone or computer. Restart both devices and try connecting the USB again.
