PC not connecting GS9+ using usb cable
The problem seemed to be not from the cable nor the PC. I think I will try factory reset the GS9+. Since the cable is not working, I cannot use Smart Switch to backup the phone. Can I use data backup to a sd card instead?
After I do the factory reset and restore the backup back to the GS9+, will the "bad stuff" whatever it is just go back to the phone?
