There are many previous questions asking about how to use the phone as camera and microphone for PC. For example:
- Use my Android phone as the camera and microphone for PowerPoint slide recording
- Using Droid as a computer microphone via USB?
However, all the answer involve installing an app in the phone. In my experience, DroidCam and IP Webcam are way too lagged. I cannot use them for online conversations, like using with Zoom. I think if there is a way to do that via ADB, then it will be much faster. We have such solutions for projecting phone's screen.
Is there a way to do so? If no, then why is that?
My Android version is 7.1 (SDK 25).
