Here are some things to check and how to possibly fix the issue:\n\n---\n\n### Why It Happens\n\n1. **Aspect Ratio & Screen Size Differences**  \n   Phones vary in screen size and shape. The aspect ratio (ratio of width to height) might cause WhatsApp\u2019s camera view or video call window to not stretch the full screen. Some phone models display letterboxing (black bars) if the app doesn\u2019t adjust to that aspect ratio. ([carisinyal.com](https://carisinyal.com/en/how-to-fix-whatsapp-camera-not-full-screen/?utm_source=openai))\n\n2. **WhatsApp or OS Version Lagging Behind**  \n   If either WhatsApp or your phone\u2019s operating system is outdated, features like landscape mode or full-screen video may not work properly. Article sources show that full-screen and landscape support was added in newer versions. ([androidcentral.com](https://www.androidcentral.com/apps-software/whatsapp-gains-screen-sharing-landscape-video?utm_source=openai))\n\n3. **Bug or glitch**  \n   Sometimes bugs in the app cause display issues. Cache buildup, corrupt files, or specific device bugs canstop WhatsApp from rendering video full screen. ([carisinyal.com](https://carisinyal.com/en/how-to-fix-whatsapp-camera-not-full-screen/?utm_source=openai))\n\n4. **Display Settings, Camera Permission, or Phone UI Limitations**  \n   - Sometimes the phone's display settings (e.g. zoomed view or display scaling) limit how apps can use the space.  \n   - The camera permission might be restricted, especially if background camera use is limited.  \n   - Features like **auto-rotate** might be turned off, preventing the screen from switching to landscape for video calls. ([androidponsel.com](https://www.androidponsel.com/kamera-whatsapp-tidak-full-screen/?utm_source=openai))\n\n---\n\n### How to Try Fixing It\n\nTry these steps. One might solve your issue:\n\n- **Update WhatsApp & your phone\u2019s OS**  \n  Check for updates in the Play Store/App Store, and update to the latest system version available. Often updates include display-mode fixes. ([techcult.com](https://techcult.com/fix-whatsapp-video-call-not-working-on-iphone-and-android/?utm_source=openai))\n\n- **Clear the WhatsApp cache and app data (if using Android)**  \n  Sometimes corrupted cache or stored data messes with how the camera/view appears. Clearing cache might help. ([androidponsel.com](https://www.androidponsel.com/kamera-whatsapp-tidak-full-screen/?utm_source=openai))\n\n- **Make sure display settings are correct**  \n  - Turn on **Auto-Rotate** so the phone can switch orientations.  \n  - Check any display zoom or full-screen app modes in your phone\u2019s settings.  \n\n- **Check app permissions, especially camera & display access**  \n  Make sure WhatsApp is allowed to fully use the camera, and if there are any special screen or overlay permissions (especially on Android), enable those. ([fone.tips](https://fone.tips/whatsapp-video-call-not-working/?utm_source=openai))\n\n- **Restart the app or phone**  \n  Quit WhatsApp fully, reopen it. If that doesn\u2019t work, reboot your device. Bugs often get fixed this way.\n\n- **Try turning your phone landscape *before* starting the video call**  \n  Some users report that calling while already in landscape helps WhatsApp initialize the video in full-screen widescreen mode. If you start in portrait it may lock into that aspect ratio with bars.

Want me to walk through that with you?"
