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)
Keeps streaming with the screen off
10 languages, dark UI, tray support
Runs fully on your device — no data leaves your computer

Quick start

Install OBS Studio (once).
On the phone: install release/FlexCam.apk and open the app.
On the PC: run FlexCam and it auto-connects.
In your video app, choose the camera "OBS Virtual Camera".

USB needs USB debugging enabled (Developer Options). WiFi needs no cable — just type the IP the phone app shows.
