  1. Greetings Bestusefultips,

    I just purchased a OnePlus 8T and it came with Netflix pre-installed, when I open the App, it states that it needs to be updated and takes me to the App Store.
    In the App Store it states “This App isn’t compatible with your device anymore. Contact the Developers for more info”.

    I contacted Netflix ,and they said I need to allow the “Unknown Sources” for the App.

    I followed your instructions above and Netflix is not listed.

    Any suggestions?

    • Uninstall the Netflix app and restart your phone. Now, download the Netflix app again and install it.

      To enable unknown sources: Settings > Apps & notifications > See all apps > Select Netflix app > Toggle on Allow unknown sources

  2. Gb whatsapp no still install

  3. Still cannot toggle to allow installation permissions for any app.

  4. Toggle switch for installing unknown apps doesn’t work 2020 moto g stylus
