One second they were there and the next second they weren't! When I click the Gallery icon, my gallery appears blank and it says "No items." I accessed the storage via USB and was able to save all the photos to my computer, but now my problem is that I can't take any new pictures - they just don't save. When I try to screenshot something, it says "Unable to save screenshot. USB storage may be in use." Other photos I try to take just disappear right after I take them. I'm glad I was able to recover all the photos I had, but I'd like to be able to take some too! Would a factory reset help? Thank you in advance!
