Is it can open the camera to scan qr code ?

✅ YES — but only with a paid Genymotion Desktop license. The camera is provided through the Media Injection widget, which is not available in the free edition. Camera resolution is fixed at 1280×720 and OBS virtual cameras are not supported; if your webcam doesn’t work there are troubleshooting steps in the support docs.

Short steps (high level)

• You need a paid Genymotion Desktop license (Media Injection widget enabled).
• Open the Media Injection (camera) widget in the running virtual device and select your webcam or a media file as the device camera.
• Point the emulated device camera at the QR code and use your app’s scanner normally.
