I am having the same issue i moved all my pictures to the external storage card to free up space but now the pics are in limbo i cant find them i just have the triangle where they use to be. the same thing holds true for apps
I am having the exact same issue and it is frustrating as hell. Especially when I get a great picture, then I go to show someone and it is ****ING GONE.. The only way that I can seem to save them if is when I take them, I immediately share them. After doing extensive research, I have narrowed it down to 2 possible issues.
1) The SD card is somehow corrupted, I purchased a 64GB SD card from eBay and I just recently read about an SD card scandal that was going on which could be the culprit. To test this, I am first going to try with a smaller card that I know works. If that doesn't work, I am going to have the pictures stored on the phone and see if that keeps them.
2) This problem really started to show itself after I downloaded an app called OneGallery, I don't really know if that has anything to do with it, or if it is completely coincidence. If replacing the SD card doesn't work, deleting this app will be the next step.
I love the phone too much to just turn it in or swap it out.
