Have had this LG phone for a couple of years and used to plug it into the USB port on my Win 10 laptop, opened File Explorer, clicked on the phone and downloaded the photos to the PC. A couple of days ago when I tried to go this the LG phone shows in File Explorer but when I click on it the right column says "This file is empty". ??? I've tried a couple different USB cables and also tried a different USB port... still the same problem. Everything it up to date and it used to work. Anyone know what's wrong???
