@IKS, thanks for the reply. Of course you were correct, the camera and microphone are showing up as USB and I was [somewhat] able to access them using a USB camera app. Actually, I tried 10 different apps all with less than hoped for results. Very frustrating; lots of crashing and freezing.
I'm beginning to wonder if the RPi is right for my project. While for the most part I am impressed by the EmteriaOS, from what I can tell the RPi doesn't seem powerful enough. Is there another Android-ready SBC that I should consider?
