If you separately record video of a session by a WiFi camera using a 3rd- party application, does it cause RC to go slow or not work properly? It's the best workaround for not having a tablet blocking your view, or a GoPro, even if you need to link the video later to see the result on the screen. Linking a video is not difficult, after you try it a few times, but you might miss the parts that aren't in the track layout. There are apps like USBCamera and CameraFi, that can record from USB, since Android does not make that easy.
