@jeromeetienne I'm having the same issue. The Hiro demo is cool but on a Nexus 6p it defaults to front facing camera pointed at me, not the rear camera making the demo sorta pointless. My main day-to-day phone is an iphone so idk how to switch front-facing camera for rear-facing in chrome on android.

Thanks for the quick reply @jeromeetienne. First and foremost, I appreciate your effort on trying to bring web ar to the world faster :). I really want to engage with AR.js, if for me it constantly just defaults to front facing camera I'm not sure what else I should be doing. Any tips? I'm continuing developing an AR.js demo for myself as well but am presuming I'll hit the same issue where it only uses front facing camera.

You to change the facing mode into environment if you want change the camera

Actually the issue is more likely to be that facingMode isn't available in the version of Chrome for Android that you might be using. I happen to have two Galaxy S8's for development but mysteriously one worked (Chrome v59) and the other one I just received did not (Chrome v56). I tracked it down to issue #290161 in Chromium bug tracker which is now marked as fixed. So, it's just a chrome version issue.

Thankfully that means you have two easy fixes:

• Use a polyfill, https://github.com/webrtc/adapter. I can confirm this poly worked for me in Chrome v56. Particularly useful if your app is already out in the wild and living in production.
• Upgrade Chrome on your device (better if you have control over your environment like I do).
