The reasons are as follows:
1. I don't own a LG G3.
I have two Android smartphones Samsung Galaxy S3 / Note3. I switched from iPhones.
2. I favor Samsung smartphones because the Galaxy S3 is the first Android smartphone which includes a native USB audio feature.
3. I also favor Samsung flagship smartphones because Samsung is the biggest Android smartphone maker: biggest smartphone maker, biggest number of smartphone owners, biggest potential number of votes for the Goggle issue "24614: Add support for USB Audio".
I don't track custom USB audio implementation because most people use stock devices.
I don't have time to track every Android device.
4. I also favor the Android L-powered Google Nexus 5 / 7 because their native USB audio would become the reference USB audio implementation in the USB DAC industry: USB audio will be included in every USB host-featured Android device, the dominant computing device.
BTW, I did inform people about your LG G3-based setup.
