I have a S4 model # SCH-R970 ver 4.4.2, and I am having issues when I transfer photos,(via USB cable) that I have downloaded on the phone, to my PC, the files are not veiwable (just shows camera icon) Facebook, Twitter, Messenger photos are fine, just the downloaded ones don't show. And now I'm have issues saving some Facebook photos to the phone (error saving photo) comes up.Is there an update that I missed, because I didn't have these problems before.Can someone please help me.Thanks
