Android App on Avaya Vantage K175

[CamilleOLLIE]

Hi,

we have a bunch of Avay K175v3 Vantage.

I tried to setup 3CX App on those Android tablets. But i'm facing an issue : the only triggered camera is the rear one. And it seems to be hardcoded in the application.
The screen stay black. Process is cancelled a few moment after.

Is there a way to register with the front cam ?

Please note that the 3CX Mobile App for Android can only access the cameras that are exposed and allowed by the device's OS.

With a device such as the Avaya K175 Vantage, this behavior may occur if the rear camera is the one exposed to third-party applications. In that case, the app will be unable to access the front camera, which would explain the black screen and the cancelled process you are experiencing.

For this kind of behavior, I would recommend contacting the device vendor to confirm how the cameras are exposed at the OS/firmware level, as there is no option within the 3CX app to force the use of an unexposed camera.

The front camera is working well with every other apps : qrcode reader, teams… only 3CX is not working.

My researches get me into an information where the camera id can be enforced, according to this code :

private int findFrontFacingCameraID() {
int cameraId = -1;
// Search for the front facing camera
int numberOfCameras = Camera.getNumberOfCameras();
for (int i = 0; i < numberOfCameras; i++) {
CameraInfo info = new CameraInfo();
Camera.getCameraInfo(i, info);
if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
Log.d(TAG, "Camera found");
cameraId = i;
break;
}
}
return cameraId;
}

The current behavior might also be related to a compatibility behavior between the device itself and the app. Could you please mention which is the 3CX Android App version and the current Android OS version installed?
