• Switch to Wi-Fi: A strong and consistent internet connection is required for error-free WhatsApp video or audio calls, so if call quality is an issue, try switching to Wi-Fi rather than mobile data. This will help with poor video quality and voice problems.
• Make sure your cameras are clean.-Believe it or not, many times the blurred image of video calls is caused by filthy camera lenses, not by a bad internet connection. To avoid this, use a cotton swab or disposable tissue to clean your smartphone's front and back cameras.
• Select a well-lit location. When making a video call, many people make the mistake of standing behind the light or windows, which causes their image to appear dark and indistinct. Choose a white background with a lamp in front of you, and your selfie camera will automatically adapt to provide the best image.
• All downloads will be paused. This advice will assist you in avoiding overcrowding during video -conversations. To make your smartphone work faster, you must pause any downloads on your mobile device; once the call is completed, you can resume everything as it was.
• .Shut off any apps that are running in the background.-To prevent your phone from overworking or even depleting its battery quickly, shut all programs that are open in the background and that you are not using before initiating the video conversation.
