I plugged in my iPhone (5s) to my laptop and all it wants is to save my photos to the photo app and I did that. But when I go to iTunes to backup my whole phone it doesn't show up. The little phone icon doesn't show up and when i go File>Devices-Everything in the devices tab is grey like my phone isn't plugged in (my name is also grey when I go to account). It may be that I don't know how to work the latest iTunes (which I have). I've tried plugging in my phone when iTunes is opened and closed, I've tried restarting my computer and trying to see if my iPad would work (and it doesn't). What am I doing wrong?
