I am trying to transfer my pictures/videos from my Motorola Razr M to my computer. I was able to do this in April, but since then have been unsuccessful. My computer doesn't seem to be recognizing that I have a connected device. I know it's connected because the phone is charging through the computer's USB port.
I have tried to follow the instructions below, but I am stopped at number 2 because there are no portable devices listed in my computer. I've gone through all sorts of things on my phone to try to make it a USB computer connection, but I'm thinking there is some sort of easy transfer button I used in April that just doesn't exist anymore.
My phone is completely filled up and the memory is already used. I do have a micro SD card in it, but that is also filled so I need to replace that. I just got the stupid phone earlier this year. I should have returned it when I had a chance but now I'm stuck with it for another year and a half.
