Full Screen Not Working

In an app I was on, I was able to activate Fullscreen with the f11 button, but now it says that block camera and mic mode will be turned off/on instead. Is there any way to activate Fullscreen without needing the f11 button

    Hi. I'm David, and I'm happy to help you.

    It looks like your keyboard's function keys have been toggled to their secondary hardware actions. This is why pressing F11 currently controls your camera and microphone privacy modes instead of triggering the traditional full-screen mode.

    This behavior is usually caused by a feature called Fn Lock (Function Lock), which inverts the action of the F1–F12 keys.

    As a quick workaround, you can try pressing Fn + F11 at the same time to see if it triggers full-screen. Holding the Fn key forces the keyboard to register the classic software command.

    To help you disable this permanently, so you only have to press F11:

    Could you please reply with the manufacturer and model of your PC? (e.g., Dell Inspiron, Lenovo ThinkPad, HP Pavilion).

    Different brands use different keyboard shortcuts (like Fn + Esc or Fn + Caps Lock) or specific built-in software to toggle this lock, and knowing your specific model will allow me to give you the exact steps.

    Looking forward to your reply.

    On Windows, full screen can be toggled in several ways without using the F11 key directly.

    1. If the app is a browser (for example, Microsoft Edge) and F11 is remapped to camera/mic control on the keyboard, use the app’s own menu:
      • Look for a menu option such as View > Full screen or a full-screen icon (often in the top-right of the window or video player).
      • Many video players inside the browser also have their own full-screen button (a square/diagonal arrows icon) that doesn’t rely on F11.
    2. If the app is a Windows Store/UWP app that supports full screen, the developer can provide a full-screen toggle in the app UI. Internally this is typically implemented with ApplicationView.TryEnterFullScreenMode() and ExitFullScreenMode(), so the app may expose a button or menu item to switch modes without needing F11.
    3. Some apps and environments (for example, Visual Studio) have their own keyboard shortcuts for full screen that don’t use F11. In Visual Studio, for instance, Shift+Alt+Enter toggles full screen mode instead of F11.
    4. In Windows 11 gaming scenarios using the full screen experience (FSE), full screen is controlled via:
      • Windows logo key + F11 to enter/exit the full screen experience.
      • Windows logo key + G to open Game Bar and use the on-screen controls.
      • Windows logo key + Tab to use Task View and switch between apps. On touch devices, swiping up from the bottom opens Task View, from which full screen apps can be managed.

    If the physical F11 key is permanently remapped to camera/mic control, the only options are to:

    • Use the app’s built-in full-screen button or menu command, or
    • Use an alternative shortcut the app provides (like Shift+Alt+Enter in Visual Studio), or
    • Remap the key at the keyboard/driver level (if the keyboard software allows) so F11 is available again.
