For most people, the standard background or theme display on WA feels very boring. WA allows users to change the background or theme according to the user's wishes. You can change the background or default theme of the application with various images, including your own photos or other images you want. You can also try using the WA Wallpaper Package which can be downloaded before use. Even more fun, WA has improved the background changing feature by allowing users to install different themes or backgrounds on different contacts, and they can also replace the WA background with their own photos. Hope it is useful
