I think the problem is related to the difference between front and back camera. I re-tested with the test app using both cameras. Here's the result:

1. Open getUserMedia app > Select Back Camera > Open Camera app > Overlay appears.
2. Open getUserMedia app > Select Front Camera > Open Camera app > Blank camera preview appears (no overlay).

Since the Loop app uses the front camera, I was unable to get the overlay when I opened the Camera app, which has the back camera as default. Both 2.1 and 2.2 display the same behaviors.

--- More Notes ---

1. The logcat shows the Camera app preview failing to start, which due to the pre-init camera hw (which opened!) shows up in the DOM-layer as a setConfiguration() failure, for which there is not callback/promise/event. This needs to be mapped to a suitable onError callback/promise/event. This is why the screen stays black with no error.

2. Shortly after the Camera app preview fails to start, the following occurs in the logcat:

So the "DAEMON DIED" failures are propagating to the WebAPI, but due to bug 1097835, aren't getting seen/handled.
