The camera on my D1 is having issues. I'm not rooted. When I take a picture, it acts like it's taking it...flash goes off, little click sound, it focuses, etc. But when I look at the picture in the gallery, it's nothing but a blank square. The file size is 0. Does anyone know if there's anything I can do? Does a factory reset wipe all data off the phone? I really don't want to lose all my apps and have to re-download, if I don't have to. Thanks!
