When I deployed on my own server, the android runtime called the front-facing camera.

I think I have a solution to the camera preference when using mobile.
The `na… vigator.getUserMedia` function is deprecated and you should instead use the newer `MediaDevices.getUserMedia` function. The [link](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) for the docs.
in your [Threex.ArToolkitSource.js file](https://github.com/jeromeetienne/AR.js/blob/master/three.js/threex-artoolkitsource.js) at line 143 should then be changed to
```
var constraints = { video: {
facingMode: "environment"
mandatory: {
maxWidth: _this.parameters.sourceWidth,
maxHeight: _this.parameters.sourceHeight
}
};
```
And if someone wants to instead use the 'selfie' camera they change "environment" to "user". You can even make a button to choose between the two.
However this might result in you changing a lot of code possibly
Here’s the solution
How can I change it?
Hi @chuxinhao ,
I think your code is correct, the issue may be a combination of browser/device that isn’t supporting the getUserMedia constraints given.
Facing mode is the preferred starting camera but it won’t always guarantee that would be the case. This isn’t specific to AR or Playcanvas, but how getUserMedia() is implemented and supported on each browser/device.
