Android devices come with a variety of different messaging apps, but there is one that is always in the background and can be easily accessed without having to open the app: WhatsApp. If you want to change the message background on your Android phone, there are a few steps you can take. First, open WhatsApp and sign in. Then, under “Settings,” select “Message Background.” Under “Backgrounds,” choose which app you would like to have your message background displayed on. If you only want to display messages from WhatsApp, select “WhatsApp.” If you want to display messages from other messaging apps as well, select “All Apps.” Once you’ve selected your app’s message background, hit “Save Changes.” Now your message will be displayed in the same color as your WhatsApp chat badge.
