I have an LGG3 and I've had no problems with it until the recent marshmallow update. I didn't notice it until a few days after I updated it, but to folders of pictures that I had in my gallery just turned to a gray screen with a triangle in it. Everything is saved to my device, I've tried backing up my pictures on the cloud, putting them on my computer and it just doesn't work. These pictures wean a lot to me and it makes me angry how they're all gone now. If anyone can help that would be greatly appreciated.
