Can't Change Wallpaper?

[AC Question]

i have samsung galaxy s5 and i recently updated it to version 5.0

after i updated i noticed that some pictures i cannot use it as my wallpaper for home and/or lock screen while others are still fine

for some picture it's normal and the whole crop the image to fit the wallpaper thingy comes up

but for some other the crop thingy is still there but the image is black and when i click save it says unable to save cropped image


there's no difference between the pictures, and the pictures that doesn't work now worked perfectly fine before i updated

does anyone else have this kind of problem? and does anyone know how to fix this??

Are they all the same file type - jpg, png, whatever? Or is there a difference?

hi, im the original poster!

some pictures are jpg and some are png, but i dont think its the type that matters because some png works, and some doesnt, same with the other types.
