AT&T Avail - I choose the picture I want to view full screen and the only options I have available at that point are "save" and "discard". I just want to keep the pic full screen and go to the next picture in the folder. I've tried swiping and tapping and the only result I get is the zoom changes. To view another picture I have to hit the back button and choose another pic. What do I have to do to view full screen pics in a series?
