The Problem

Q: How do you set a solid color wallpaper on your Android device?

A: You use a tiny 1x1 pixel image with the pixel set to that color (Black, Pink, or #FF5678). Simple, fast, and memory-friendly.

This works on most Android devices (including Nexus devices and others that run stock Android). The system knows how to fill the entire screen with that one pixel, giving you a full solid color wallpaper.

However, there are some Android devices that give errors immediately after setting the 1x1 pixel image wallpaper: Unfortunately, System UI has stopped or Unfortunately, Home has stopped. Trying slightly larger image sizes (2x2, 3x3, 4x4) also fails. For some devices, you need a 32x32 pixel image to finally get your color wallpaper working.
