Someone just posted one on a thread in this forum. I think it's the "Wallpaper of the day" thread or something like that.

Have you tried the app called Backgrounds? Get it and check in the Patterns category.

 

By the way ... all you have to do is save a 10x10 pixel black square jpeg in any of the media folders on your sdcard and you're all good.

 

Hold your finger of choice over the camera, snap picture, set as wallpaper? Usually turns out quite black.

 

This is what I did except I rested the lense aginst my jeans.

 

Haha yea that prolly the easiest way to do it..

 

Try the Simple Droid Tools' "Remove Wallpaper" from Google play.

It replaces the current wallpaper with a entire black picture.
