When I plug my Samsung Galaxy S4 into the computer to move photos over, I end up with all kinds of junk photos that I didn't actually take. I thought they might be from websites I was visiting, but there are all kinds of weird photos....food, lipstick, people I don't know, puppies....it's crazy. I only have about 100 pics on my phone and when I plugged it in this morning, it was trying to download 500+ pictures. What is this and how do I stop it?
