Under gallery, I've tried setting wallpaper from images stored. I'm experiencing two problems: 1) When using the green border to select the part of the image I'd like, it never stretches to the full size of the image. It maxes out at about half the size of any image. 2) Once cropped after clicking set as wallpaper, the wallpaper shows way too zoomed in and I lose at least half the image I cropped. Please help!
