Hi, Does anyone have any idea why I cannot connect my Nexus 5 to my computer via USB? Before 'upgrading' to Android 6, and whilst on 4.4.4, I could connect using a USB cable and, for example, transfer photographs to my computer. It appears that I can no longer do this. In fact, when I connect it, the phone shows up on 'This PC' alongside the C: drive, but when I click it, it shows as being 'empty'. Despite this, there are certainly photographs on the phone. In order to transfer one to my computer, I was obliged to send it via e-mail! Hopefully, it is some sort of setting that has changed due to the upgrade. Can anyone please offer any advice? If I cannot solve the problem, is it at all possible to revert to Android 4.4.4?
