Photo crashing and continuous updates?

[Angela Smith1]

So, generally speaking, I love my phone, however,,, whenever I try to take a picture, it shuts down. The gallery deletes half a photo before it's done loading. Which directly connects to my second problem, my phone has spent the past 4 hours saying it's searching the SD card for backup assistant. Has anyone else experienced this extreme issue with backup assistant, and if so, what is the solution? Thanks!
