Unfortunately I can’t run Cyanogenmod on all of my Android devices (more on that tomorrow), but if you want to save some memory and CPU cycles and, depending on your device’s display, perhaps even increase your battery life by a few dozen minutes, there’s an option.
The Cyanogenmod No Wallpaper feature is available as a small app in the Play store. Simply download it, then tap and hold your home screen and you can select No Wallpaper.
Besides the benefit of decreased memory usage and increased battery life, I found the minimalist look quickly grew on me.

Do you know if using this app saves more cycles than creating a solid color (say, black) background image?
I’ve heard that suggestion, and I’m not certain if it’s truly displaying nothing, or just displaying a single, solid color background image.
That would be a good thing for me to test, once I get a few other projects behind me. I’ve spent all week trying to get a custom ROM loaded onto the world’s weirdest Samsung phone.
