I need your help, MacRumors! All of a sudden after a year or two of use, my iPhone 5 will not take any pictures. The camera app will open, but it will be a blank black screen. I cannot move the little slider over to video, panoramic, etc. Also, when I try to take pictures in Instagram and Snap Chat, I also cannot take any pictures. I have 4.3GB of space available on my 5, so photo storage isn't an issue; however, I've been getting messages lately that my phone cannot be backed up on iCloud because I don't have enough space, but clearly I do. I'm running iOS 7.1.2. Thank you in advance!
