Im using a Moto X sencond gen eunninf on 5.1. I have a problem where some of my vacation photos are showing in the gallery and Photos as blank. When you open the thumbnail it is still blank. Photos taken before and after appear fine. I know this used to periodically happen with other versions of the OS but those solutions haven't solved my problem. My battery was low and I was in a remote rural area that had no service but I don't think this should matter. Any ideas?
