    Does anyone get artifacts/bands when trying to use a solid color for wallpaper?

    Here's an unedited screenshot: You can sort of see the bands up top below the time and then in the lower half above the dock.

    It's a lot more noticeable on the actual iPhone so I brightened the screenshot I took:

    I'm using this image as wallpaper and it's basically a solid blue image.

    I can view the wallpaper in photos without any artifacts.

    Simple.

    The OS applies a downward transparent-to-black gradient on any background image you set. This is presumably to make the 4 dock icons stand out a bit from the rest of the home screen.

    When you apply a gradient to a solid color, you get what appear to look like "artifacts" because the gradient is transitioning from one color to the other.

    You could try applying a manual gradient yourself in Photoshop or another program, which may make the effect less drastic.

    That was actually one of my first thoughts because of the stripes in the lower half. But how does that explain the stripes at the top of the image? If it was a gradient then the top would be solid.
