WhatsApp is a messaging app with over 1 billion active users. It’s also one of the most popular video calling apps on the market. If you want to make a video call with someone who uses WhatsApp, but their background is different from yours, there are a few things you can do. First, open WhatsApp and select the person you want to call. Next, tap on the three lines in the top left corner of the screen. This will open up your chat window. Next, tap on the “Background” option in the bottom left corner of your chat window. This will bring up a new window where you can choose between several background options. If you want to change your background completely, tap on “Choose Background Image.” You’ll then be able to browse through your photos library and select an image that matches your new background color. Once you’ve selected an image, tap on “Set Background.” Finally, tap on “Call.” Your call will now use your new background image! ..
