It turns out that this was already fixed since Chrome 59.
The problem is that I was testing with a Canary based on 57.

Have you tried a pixel XL? I can not make this work.

Reopening as per #3.

I don't current have a Pixel XL available for testing.
What Chrome version are you running? How does it fail?

59 on 7.1. It fails in that it doesn't honor the facingMode constraint.

How does it not honor it?
Do you always get the front camera, always the back camera, always the opposite of what you request, a random one?

I just got access to Pixel XL running Chrome 59 and Android 7.1.1 and the facingMode constraint works as expected, just like every other model I have tested.

I just tested with https://jsfiddle.net/8e1cLn1j/10 and https://jsfiddle.net/8e1cLn1j/11

Can you provide a jsfiddle that fails on your phone?

cgfarmer4@gmail.com: Please also try with the latest Chrome stable, which is Chrome 60.

1. Chrome 60 is not available in the Play Store yet. Its only on the beta
channel.
2. Your code works fine on 59. It doesn’t make sense to me why you call
getUserMedia 2x though. This is what allows it to work. The API should only
have to fire once.

cgfarmer4@: 
The script is just a minor variation of the script for  bug 746534 , which you also reported. That bug involved two calls to getUserMedia and I did not bother removing the first call.

Please also try with https://jsfiddle.net/guidou/9k41rg0b/2 and https://jsfiddle.net/guidou/9k41rg0b/3 which contain a single call and also work fine on the Pixel XL I'm using for testing.

Chrome 59 stable or later should work fine. I asked you to run 60 just in case you were inadvertently running an early development version of 59.

Also, can you provide a script where gUM fails on you Pixel XL to see if it also fails for me or to check if it's a bug in the application?

It does appear this has been fixed since Chrome 59.I had last tested all of
the use cases in 57 so that would coincide with your findings.

Thank you for all your help and exhaustive testing with these couple bugs.
