Caution
FlexCam requires OBS Studio to be installed. It uses the OBS Virtual Camera driver to expose your phone as a webcam. Install OBS once — you don't need to keep it open.
What it is
FlexCam streams your Android phone's camera to your PC and exposes it as "OBS Virtual Camera", so any app (Zoom, Teams, Discord, your browser, OBS) can pick it as a webcam. It works over USB (via ADB) and WiFi, and switches between them automatically if one drops.
- Hybrid USB + WiFi with automatic failover
- Auto-connects when your phone is ready — no manual steps
- Front / back camera switch
- Auto portrait/landscape (follows the phone's rotation)
