I used to have no problem connecting my phone to my laptop to transfer photos and music, but recently I cannot get my phone to connect for that at all. It will charge when plugged into the USB port with a charger cable, but I can't do anything else with it. I have it unlocked, and I open the notifications scroll down like I'm supposed to, but the USB connection options button never appears. I've tried three different cables and all four USB ports on my computer but none of them have worked. My computer doesn't make the recognition sound at all yet it still charges without issue. But given that, I can't tell if it's the computer or the phone that has a problem. It's very frustrating though, I have a lot of new music I want to add but my phone won't connect.
