I have a Droid 4. I have about 94 pictures taken with the camera. When I plug the USB to my phone, there are a couple folders. One is "pictures" This folder has nothing. The other is "Saved Pictures" This one has 5 pictures. I clicked through the rest of the folders but did not find the other pictures. When I take pictures with my camera phone, am I suppose to save this pictures as something or move them?
