So , after updating the system a few days ago on my S20 Ultra , i now discovered that I can not access anything on my SD card. I tried USB tethering by a cable connecting to my PC and notice its not working either . I access the Connection setting , and it appears like this Screenshot below ( no USB devices cennected ) , although the phone is said as charging by the cable.
Here's things i tried but not work :
_ Tried 3 cables ( Usb to usb C ) , meaning the cable is not the problem.
_ Restart , Power off / on multiple times.
_ Take the Sd card out and insert again.
Please fix the issue.
usb tethering is hot spot connection using cable.

go back 2 times, at the bottom, there is new option, developer options
scroll down and find 'Default USB configuration'
click transgerring file.
then try reconnect to your pc again
