Android's working on its own Continuity Camera to turn your phone into a webcam

Google has supported external USB cameras in its mobile OS since Android 4.3 Jelly Bean, so you’ve long been able to plug a webcam into your phone or tablet and use it for video calls. Third-party apps have also managed to make the reverse possible, giving you the option to connect your device to a computer and use it as a webcam — however, it appears Google is now working to make this a built-in feature of Android, similar to Apple's Continuity Camera that allows iPhones to function as webcams for Macs.
