The popularity of Android Apps has gone from being initially centered around Smartphones to several other hardware types [Android Tablets, and streaming boxes like the NVIDIA Shield and Amazon Fire TV/Stick] and is now built into a number of famous brand televisions.
Apart from running on Android the Apps are now also available on other operating systems including ChromeOS {Chromebooks & Chrome Boxes} and Linux laptops and desktops.
Consequently the App Help information provided by these Help sites was spread, and occasionally duplicated, over different places so to simplify things the information is now centralised to App-Info4U that can be referenced by the other Help sites as necessary.
If your smartphone runs Android 14, or later, simply connect it to your chromeOS system with a suitable USB cable that must be of reasonable quality and importantly support data transfer as well as just a basic power connection.
Check your notification tray and click the option labelled Charging this device via USB.
At the bottom of the bottom of that menu, you’ll find the new Webcam option.
Once you have it enabled, your device will see your phone as an external webcam, with the option to swap between front and rear cameras, and adjust zoom levels.
You can even lock your phone to save battery, and when you’re ready to go, your phone’s camera will still be waiting.
Apps like Discord, Zoom, and Google Meet on your computer will recognise your Android phone as the “Android Camera”, so when you select that option for your video input, it will just work. It’s that simple.
