    Hi Dragutu

    Thank you for your asking. Are you asking phone-USB cable-PC issue? Kindly try some stay-at-home troubleshooting tips below:

    1. Check your USB Preference settings

    Settings>Connected devices>USB>file transfer

    2. Make sure that the USB configuration fits your device

    3. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

    # How to enter and exit "Safe Mode"

    4. Please try "the Factory Reset" 

    Settings>System>Reset options>Erase all data(factory reset)

    Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
