I can see all of my photos in Gallery but since the JB update I can only view about a 1/4 of them when viewing from my pc, which is running Win7. I've tried it on a couple of pcs with the same results. I've got over 18 GB of space available, so it is no a matter of being overstuffed (not that that should matter).
I installed QuickPic on the Nexus, thinking maybe that would do the trick but no luck. Any thoughts?
